What direction should IMSA take with prototypes?

There are two questions around the IMSA WeatherTech SportsCar Championship's top class. For 2019 the question is if IMSA should split the Prototype class into separate DPi and LMP2 classes. For the 2020s the question is if IMSA should align its top class with the FIA World Endurance Championship.

Should IMSA split the prototype class?

The idea of splitting DPi and LMP2 cars into separate classes gained traction after the early season was dominated by the DPi cars. However, the Sahlen's Six Hours of The Glen saw Oreca LMP2 cars achieving a 1-2 win despite the Pro-Am driver lineups JDC-Miller Motorsports and CORE autosport were running.

Watkins Glen may be the track best-suited to LMP2 cars after its repave some years ago. On such a smooth surface, the DPi cars won't benefit so much from the custom-made shock absorbers as opposed to the spec shocks of the LMP2 machines. Besides, on a flowing layout like Watkins Glen, the DPi machines won't benefit as much from any torque advantage they may have.

The DPis may be superior cars and the Balance of Performance is restricting them a lot. However, the idea of the joint DPi-LMP2 Prototype class was to use the best LMP2 car as the benchmark for the BoP and the DPi manufacturers should know it. If an LMP2 car occasionally beats a DPi car, it shows the BoP has allowed the inferior LMP2 cars to be competitive. That's the purpose of the BoP, to put cars of different performance on the same line. I'm sure IMSA is doing their best to make the BoP fair but it's not easy to balance different cars. Sometimes the LMP2 cars have the advantage, like they did at Watkins Glen, though most of the times the DPi cars have been the fastest.

A major reason for the better results of the DPi teams is that they are running all-Pro lineups as opposed to the LMP2 teams running mostly Pro-Am lineups. Last year's only win for an LMP2 car was achieved by the VisitFlorida-sponsored Sprit of Daytona Racing with an all-Pro lineup. Besides, Team Penske had a strong performance at last year's Motul Petit Le Mans with an Oreca LMP2 car while running an all-Pro lineup.

In a way, splitting the Prototype class could make the WeatherTech Championship more attractive also to LMP2 teams. Instead of being also-rans behind the DPi cars, the LMP2 teams would be racing for a class win behind the DPi cars.

Even if there was a separate podium for the Pro-Am LMP2 cars, I still don't see why the best LMP2 car couldn't be used as the benchmark for the BoP of the DPi cars as DPi needs a BoP anyway. If there's an LMP2 team that wants to go for overall wins with an all-Pro lineup, why shouldn't they be able to do it. If a WEC or ELMS team wants to race at Daytona or Sebring, it's very difficult to get a DPi car whereas currently they can use their own LMP2 car. As all the DPi cars are derived from the LMP2 cars, I don't see why the inclusion of the Gibson-powered LMP2 cars would make the BoP process that much more difficult.

The biggest problem in balancing the DPi and LMP2 cars may be the development of the DPis as opposed to the homologated LMP2s. However, a simple solution would be to limit the DPi cars development. They all are already faster than the benchmark LMP2 car so you could just freeze the DPis' development. That way the BoP process would be less of guessing game after the winter break.

In short, I'm all for a greater recognition of the top Pro-Am LMP2 cars. But I still hope LMP2 is used as the benchmark for the BoP of the DPi cars, allowing the LMP2 race for overall wins.

Should IMSA align the top class with the FIA WEC

The ACO has released details of the new top-class prototypes of the FIA World Endurance Championship. Like the DPi cars, the new top-class prototypes in the WEC will feature manufacturer-specific styling cues, though instead of the "LMP-look", the new cars will be reminiscent of the manufacturers' road-going hypercars and will be hybrid-powered.

The new prototypes are set to make their debut in the 2020-21 WEC season. IMSA will continue with the DPi cars until the 2021 season, however it may align its top class with the WEC for the 2022 season.

A global top class would have certain benefits. For the first time in decades, the same cars could go for the overall wins at Daytona, Sebring, and Le Mans. Besides, a global top class could be more attractive to manufacturers; for example Ford chose to enter GTE instead of prototype racing because it allows racing in both the WEC and IMSA. On the other hand, some manufacturers might choose to compete only in one series, like Corvette does in IMSA, and Ferrari and Aston Martin in the WEC with their GTE cars, entering only the marquee races of the other series.

However, the cost of the WEC's new top class may keep IMSA from adopting the rules. While the budgets will go down significantly from the LMP1-hybrid budgets, the WEC's new class will still be more expensive than the DPi programs are.

I'd happily see a common top class for the WEC and IMSA. But it shouldn't come at the price of the product IMSA has now. Maybe IMSA could gain a new manufacturer or a few of them. Then again, some of the current DPi manufacturers might deem the new top class to be too expensive. If a global top class would mean less manufacturers than DPi currently has, then I hope IMSA will go its own way.

Privateers could be the biggest losers if IMSA adopts the global top class. Although the OEMs will have to sell the hybrid system at a given price to private constructors, a privateer program in the new top class will likely by more expensive than an LMP2 program or a customer DPi program like Tequila Patrón ESM's Nissan program currently is. Plus there is no guarantee the privateers will have an access to winning cars in the new top class like they currently have in IMSA's Prototype class.

I'm not convinced the WEC's new top class would further enhance the competition in IMSA. If anything, it could turn the Prototype class into a playground of factory teams, forcing privateers and some of the current DPi customer teams into other classes. If there is a less expensive way attract a good number of manufacturers and privateers, IMSA should choose it over a common top class with the WEC. Maybe LMP2 like currently, instead of LMP1 or whatever the WEC's top class will be called, is a better base for IMSA's Prototype class. Once the current LMP2 regulations expire in 2021, maybe IMSA should create a new DPi class around the new LMP2 rules.

Sportscar organizations need co-operation, also in scheduling

The date change of the Fuji round of the FIA World Endurance Championship has left many drivers and fans disappointed as the new date will clash with IMSA's Petit Le Mans as well as Super GT's Autopolis round. While the new date will allow Fernando Alonso to compete the full season at the wheel of Toyota's LMP1 car, the date change creates a clash for many drivers who have a dual campaign in the WEC and IMSA or Super GT.

For sure it will be a boost for the WEC's attention to have a driver like Fernando Alonso contending for a world championship in another series besides F1. But after originally choosing the Fuji date exactly to avoid the clash with Petit Le Mans, the FIA and the ACO have betrayed the sportscar community with this date change, catering only to one star driver's needs.

Sportscar racing is a niche sport within all of motorsports and it is divided between multiple organizations. To help to grow the sport, the organizations need to co-operate in scheduling (as well as other things). Many drivers and even some teams compete in multiple series. I'm sure the WEC fans have happily seen drivers like Mike Conway in IMSA's endurance races and André Lotterer in at the wheel of GT cars at Spa and Nürburgring. Interestingly, Alonso's teammate Conway is one of the drivers affected by the date change since he's an additional endurance driver for Action Express Racing in IMSA.

As the WEC is changing to a winter schedule, it shouldn't be too difficult to create schedules with IMSA to avoid conflicting dates. Super Formula and Formula E already avoid clashes with the WEC. The two leading sportscar championships, the FIA WEC and IMSA's WeatherTech Championship, should do that for each other's schedules to enable drivers' dual campaigns. If the WEC tries to avoid conflicting dates with F1, it becomes more difficult as F1's schedule is only likely to grow and the FIA only requires it to avoid a clash with the 24 Hours of Le Mans. And anyway, an active F1 driver competing full-time also in the WEC will still likely remain very unusual despite Alonso's 2018-19 campaign.

It's not only the WEC to blame. Fortunately it hasn't been the case in last two years but there have been cases of an IMSA race in the same weekend with the Total 24 Hours of Spa, with drivers missing that weekend's IMSA race. The Spa and Nürburgring 24-hour races are the biggest GT races in the world where major manufacturers want to field the best drivers from their payroll. Blancpain GT Series had originally scheduled their Silverstone round in the same weekend with this year's Nürburgring 24 Hours, yet it did the right thing and changed the Silverstone date to allow drivers as well as teams to race at Nürburgring.

Having accepted Fuji's date change, the FIA and the ACO seem very ignorant towards sportscar drivers and other series, abandoning the original plan of avoiding a Petit Le Mans clash. The WEC organizers have obviously asked IMSA to change the Petit Le Mans date now to not clash with the WEC at Fuji, though IMSA should really not let fans down with a date chance at this point. Some fans had already booked a trip to Japan for the WEC, only to see the date changed now. IMSA must not do the same for the fans going to attend Petit.

ACO, IMSA need a shared vision of sportscar racing's future

The LMP1 class is set for an overhaul of its technical regulations for 2020 and beyond. A possible future direction is aligned LMP1 and DPi regulations, creating a common top class for the FIA World Endurance Championship and the IMSA WeatherTech SportsCar Championship.

While a common top class would be desirable, the differences in the ideologies of the WEC and IMSA may be problematic. LMP1 is more of a technology-driven class whereas the DPi class is aimed to be cost-effective. Some compromises would be needed to create a single class.

In a way, the WEC and IMSA are like Formula One and INDYCAR. In both cases, there are a FIA World Championship and its American counterpart. While it's good to have alternatives in open-wheel racing that complement each other, sportscar racing is a smaller sport and would do better without unnecessary division.

If anything, the LMP1-DPi division is like the CART-IRL split. Both are examples two different visions of the same sport. Just like the American open-wheel sport's recovery after the unification has shown, it would be better also for sportscar racing if its sanctioning bodies shared the same vision of the future of the sport.

The ACO and IMSA may have different goals for the top classes of the World Endurance Championship and the WeatherTech SportsCar Championship, however they have the same needs. In the best interests of the sport, those two organizations should put their own goals aside and concentrate on the common needs and create a common class structure. Instead of having manufacturers divided between two series, it would be better to see them all in both series.

Even if the WEC and IMSA adopted a common class structure, both series could still have their own identities. The WEC would have Le Mans, IMSA would have Daytona and Sebring. While the WEC goes to modern F1 venues around the world, IMSA has old-school road courses and even some street courses in North America. Even with a common class structure, the WEC and IMSA would compliment each other like F1 and INDYCAR do.

Different goals, same needs for top sportscar classes

With Porsche leaving the LMP1 class after the current season, Toyota is set to remain as the only OEM brand in the top class of the FIA World Endurance Championship. Meanwhile the IMSA WeatherTech SportsCar Championship will get its fourth OEM in Acura in the top Prototype class for 2018.

Both the ACO and IMSA would surely welcome new manufacturers into their top prototype classes. Yet instead of making the manufacturers choose between the two series, the two sanctioning bodies should unify their regulations to allow manufacturers to participate in them both.

When deciding for the future of top-class prototype racing, the ACO and IMSA should look at what makes GT3 maybe the best class in sportscar racing at the moment. Although GT3 was originally intended to be a class for customer racing, there are some de facto works teams. But also customer teams can succeed in GT3, and selling GT3 cars is a business for the manufacturers.

In a way, IMSA's Prototype class is reminiscent of GT3. The DPi entries are more or less works teams, yet also the privateer LMP2 entries can succeed there. IMSA has probably the healthiest prototype class at the moment; there will be four OEMs represented in 2018, though it's also an affordable class for privateer teams.

While Toyota is set to be the only OEM left in LMP1 in 2018, there are several privateer projects to join LMP1. However, the budget cap between Toyota and those privateers may be too big to provide close racing on track. And even if the privateers could match Toyota in lap times, the hybrid technology allows a better fuel mileage Toyota, putting them at an advantage.

The main goals for the future of the WEC's top class should be affordability and parity. IMSA has achieved that with the DPis and LMP2s, although the parity comes from the Balance of Performance.

LMP1 has featured some of the most advanced technology in all of motorsports. But maybe it would be better for the class to have more cars and closer parity than feature the latest technology. If the WEC got rid of hybrid technology, it might lose Toyota, though it might gain Cadillac, Mazda, Nissan, and Acura from IMSA. Hybrid technology doesn't anymore draw manufacturers; Audi and Porsche left LMP1 for Formula E.

IMSA has a top class that attracts both manufacturers and privateers. That's what the WEC would need. Develop IMSA's prototype class into a global top class and it could be the prototype equivalent to the successful GT3 class. It would be an affordable class for manufacturers and they could even sell cars to privateers who could succeed with them. I'd like to get rid of the BoP, though the rules should remain simple to ensure a close parity of the field.

An aligned class structure would enable the inclusion of Daytona and Sebring in the WEC calendar as co-sanctioned races with IMSA, not as a doubleheader with separate races. A World Championship is supposed to have the biggest races, those two are the biggest races in the USA. Even if the FIA's bureaucracy prevented co-sanctioned races, the same cars could participate in both organizations' races and sportscar racing as a whole would be the winner.

Of course, change takes time. The new LMP1 privateer entrants have entered under the assumption no OEM can enter with a non-hybrid car. Allowing non-hybrid factory cars would not be fair for the new LMP1 privateers. The DPis are designed for a BoP class; getting rid of the BoP would not be fair for those manufacturers.

It may not be the right time to align the class structure in the next few years, though it should be the aim for the near future. The ACO and IMSA may have different goals for their top classes, though the needs are the same; an affordable class for both manufacturers and privateers with parity. GT3 would be a good example of that, apart from the need for the BoP.

GTE vs. GT3 divides manufacturers

Just like prototype racing, also GT racing is divided in two top classes. GTE is the top GT class in the ACO's and IMSA's class structures, though it's GT3 cars that are racing for overall wins in races like the Nürburgring 24h and the Spa 24h.

While both classes are pretty healthy at the moment, the division feels a bit unnecessary. There are some manufacturers (Porsche, Ferrari, Aston Martin, BMW) represented in both classes, though GTE is more of a class for manufacturers with an emphasis on factory programs (Corvette, Ford) and GT3 for manufacturers with an emphasis on customer racing (Audi, Mercedes, etc.).

There are certain differences between GTE and GT3 machines. GTE cars don't have ABS and they are built to stricter rules than GT3 cars which rely more on the BoP to achieve parity. However, also GTE uses the BoP.

Because of the need for the BoP in both classes, I don't really see any reason to keep them separated. The BMW M6 is not built to GTE regulations, though IMSA allowed a modified GT3 car into the GT Le Mans class in the past two seasons. While I like the limited driving aids of the GTE cars, I don't really see the need for the stricter technical regulations given that it's a BoP class.

The ACO surely doesn't have much need for the GT convergence at the moment, given that GTE is a healthy class at the moment and has been gaining new manufacturers. But wouldn't it be great to see Bentleys or McLarens in the GT class at Le Mans, or Corvettes or Ford GTs racing for the Nürburgring or Spa 24-hour wins?

The SRO, the sanctioning body of the Blancpain GT Series, has been trying to preserve the pro-am nature of the GT3 class. That's understandable; as long as there's customer racing, the class is a more sustainable business for the manufacturers. If it gets predominantly factory racing, it's mostly spending for the manufacturers.

I'd like to see a top GT class where each manufacturer has a basic car intended for pro-am racing with an option to upgrade it for all-pro classes. That would be somewhat similar to what BMW has done with the M6 in IMSA. That would also make the factory programs more sustainable, given the customer racing business in GT3.

If all GTE cars were based on a GT3 car, we might see more manufacturers in the GT fields of the WEC and IMSA as well as in Blancpain. Instead of fighting for manufacturers against each other, the sanctioning bodies should try to create regulations that allow participation across different series. The sanctioning bodies may have different goals for their classes but their needs are the same. In a sport like sportscar racing, incompatible class structures do more harm than good.

Separate Sebring races highlight need for aligned WEC and IMSA rules

Among the changes the ACO has announced for the FIA World Endurance Championship was a return to Sebring, Florida for a 12-hour race for the first time since the series' inaugural season in 2012. However, unlike in 2012 when it was a combined race with the American Le Mans Series, the 2019 race will be run separately from 12-hour race of the IMSA WeatherTech SportsCar Championship in the same weekend.

The American Le Mans Series featured LMP1, LMP2, and GTE from ACO's classes with the addition of the PC and GTC classes. That made it easy to include Sebring in the 2011 Intercontinental Le Mans Cup schedule, the predecessor for the FIA WEC. All ILMC classes apart from GTE-Am had their counterparts in the ALMS class structure.

The classes remained the same from the ILMC to the FIA WEC for 2012, yet the class structure for Sebring was more complicated. LMP1, LMP2, and GTE-Pro were split to separate classes for the WEC and the ALMS teams, despite sharing common regulations.

2012 was the last race for the WEC at Sebring, though LMP1 machines returned for one more time in the 2013 ALMS race. In 2014 the ALMS merged with the Grand-Am Rolex Sports Car Series and LMP1 was dropped from the united series' class structure. WEC teams have still returned to Sebring from the LMP2 and GTE classes that remain in the IMSA WeatherTech Championship.

2019 will see the WEC and the LMP1 machines returning to Sebring. But the WEC and the IMSA series have grown too much apart to run alongside each other. WEC's LMP2 would fall into IMSA's P class and WEC's GTE-Pro would fall into IMSA's GTLM class, though there are some significant differences in the race procedures, like pit stops and caution periods, in the two organizations' rule books. And most importantly, IMSA's prototype teams could hardly race for the overall victories against WEC's LMP1 teams, so the two series will race separately.

I have mixed feelings about the WEC's return to Sebring. Back in the ALMS days when the Rolex 24 was for Daytona Prototypes in the Grand-Am series, Sebring was the second-most important race for Le Mans Prototypes, only behind Le Mans itself. As great as the re-unification was for American sportscar racing, Sebring lost the global top class prototypes. Sebring will get them back in 2019, though the separate races are only a poor compromise. When there are two races, which one will crown the overall winner?

The need for separate IMSA and WEC races showcases what I think is a big problem in sportscar racing, the conflicting regulations in different organizations. The competition between different organizations' series is already a bit destructive for the sportscar racing overall. Sebring and Daytona will probably never be as big as Le Mans is but a top class with limited international relevancy doesn't help either. Yet those two are bigger races than any WEC race outside Le Mans but the WEC's top class wouldn't be sustainable in IMSA competition.

The WEC needs all the classics of prototype racing. It needs Sebring and it would also need Daytona. And not as separate races for the WEC and IMSA but as combined races. The ACO needs to acknowledge IMSA controls the two biggest races after Le Mans, and the two organizations need to create a compatible class structure. Something that is affordable for privateers, what ACO is trying to achieve for LMP1, but not controlled by the balance of performance like DPi is. I wrote earlier about what I think the LMP1 class should be like.

I even go as far as suggesting the ACO and the SRO should align the GT regulations. While both GTE and GT3 are looking healthy at the moment, nobody benefits from the separation of such similar classes. GTE was initially the class for factory teams and GT3 for the privateers, yet there are factory teams in GT3 racing and privateer teams in GTE-Am. Who wouldn't like to see a Ford GT or a Corvette racing for the Spa 24 Hours overall victory, or a Mercedes-AMG GT3 or a McLaren for the Le Mans GTE-Pro victory? At the same time, the class must remain affordable for privateer teams.

Of course, aligning the classes isn't so easy because of all the ongoing projects. Privateers enter LMP1 assuming manufacturers can't enter the class with non-hybrid machines like DPis. Manufacturers have built their DPis for a BoP class so running them unrestricted wouldn't be fair. And a GT convergence wouldn't be fair for those manufacturers that have just launched a new car in either of the current classes.

I have some hope the WEC's return to one of IMSA's major events signifies the start of aligning the regulations of the two organizations. Yet March 2019 may come too soon to abandon the idea of the dual race in favor of a combined race at Sebring.

LMP1 needs a rethink following Porsche's departure

Porsche is about to leave the LMP1 class of the FIA World Endurance Championship and the 24 Hours of Le Mans, leaving Toyota as the only factory team in the class. Porsche will be the third major manufacturer in three years to leave the class; of the four manufacturers in 2015, Nissan ended its short-lived program after the first year, Audi ended its 18-year Le Mans involvement in 2016, and now Porsche is set to leave the LMP1 class in the fourth season of the program.

There are multiple privateer LMP1 projects so the 2018 grid may well have more cars than six this year at Le Mans. Another thing is if the privateer teams with more limited resources can challenge the only remaining factory team of Toyota. Also, privateer teams don't bring the publicity that a major manufacturer like Porsche or Audi did.

DPi machines from the IMSA WeatherTeach SportsCar Championship could be a way to get more manufacturers in the prototype classes at Le Mans. Cadillac, Nissan, and Mazda are already involved in the DPi class and Acura will join next year. However, DPis can't match the pace of the hybrid-engined factory LMP1 cars. Besides, the DPi class relies on the Balance of Performance. That's fine for IMSA where you don't want an expensive development war, though I prefer the top class of Le Mans is be free from BoP.

What the LMP1 class needs is competitive privateer entries but also factory teams. I'm not a fan of two-tier rules where the cash-strapped privateers have more open rules to be able to challenge the factory teams with bigger resources. Instead I'd like to see rules where it's affordable for privateers to build a winning LMP1 car or to buy one from a factory team and run independently.

The planned LMP1 hybrid rules for 2020 are very much opposite of what I'm hoping for. The hybrid technology will be even more advanced, featuring plug-in recharging during pit stops and running the first kilometer after the stop with electric power. As car manufacturers aim for better fuel efficiency and develop hybrid and electric vehicles, hybrid technology helps to attract manufacturers.

Still, expensive hybrid technology may also drive manufacturers away from the LMP1 class and prevent privateers from having success. LMP1 needs to be open for hybrid technology but it must not be mandatory.

The idea of hybrid technology is to improve the efficiency of the cars. My idea of LMP1 rules would be a maximum amount of fuel, hybrid technology allowed but not required. Set the minimum weight for a car without any hybrid systems; hybrid systems would add to the weight of the car but also to the fuel efficiency. As a result, we might see a manufacturer with an advanced hybrid system, another manufacturer with a less advanced hybrid system but also a lighter and more reliable car, and a light car with no hybrid system.

It would be up to the manufacturer to decide how much it wants to concentrate on the development of hybrid systems and how much it wants to concentrate on the development of a fuel-efficient internal combustion engine. It would be the most efficient technology winning, not the favored technology.

To make LMP1 more affordable, I think the rules in certain areas should be restrictive. In areas with road relevance, like engines, the rules must be open enough to attract manufacturers. But spending on areas with little road relevance doesn't make much sense. Limiting bodywork sets to one per season instead of current two is a welcome change in the planned 2020 rules. Advanced race car aerodynamics don't have that much relevance with most road cars, furthermore advanced aerodynamics only tend to hurt on-track racing.

No ruleset removes the issue of factory teams having more money than privateers. Yet if the rules made it harder to make gains in performance by overspending, privateers would be better able to challenge the factory teams of automotive giants. Making LMP1 less expensive would also attract more manufacturers. If privateers could build competitive chassis, a manufacturer might choose to supply (hybrid) engines to two privateer teams rather than run an own factory team.

To make privateers able to succeed in LMP1, I'd also like to see customer cars. The current LMP1 hybrid cars require factory support, having prevented privateer-run Audi R18s after Audi's departure. I'd like to see a rule where a manufacturer must sell a car of a previous generation to a potential customer at a maximum price. Five million dollars would be a good price for a car that would no longer have any use outside exhibitions, and the price should include the factory support needed. Customer cars would help to bring hybrid technology into privateer racing.

In short, the level of hybrid technology should not be determined in the rules, instead let the manufacturers choose it themselves based on their budgets. With a given amount of fuel, it's the most efficient car that wins, regardless of if it has advanced hybrid technology or no hybrid technology at all.

My vision of the future of IMSA's Prototype class

ACO, the organizers of Le Mans, announced the new rules for Le Mans P2 cars starting from 2017. Without going into details, ACO will approve four chassis suppliers and one engine supplier. IMSA, the sanctioning body of the Tudor United SportsCar Championship, is planning to adopt a modified version of the P2 regulations for their Prototype class. But IMSA and ACO have different needs. P2 will be IMSA's lead class with manufacturer involvement and all-pro lineups whereas for ACO it's a pro-am class with no manufacturer involvement. The proposed solution to that issue is allowing multiple engine manufacturers and manufacturer-specific bodykits in IMSA with also ACO-spec P2s being allowed there. ACO would allow multiple engine manufacturers only at Le Mans with their performance balanced and all cars using the ACO-spec bodykits.

Le Mans-compatibility is an issue here. Spec bodykits might make balancing the performance easier but it would also mean IMSA teams using engines that are designed to use with a different bodykit with different air intakes, etc. So probably the teams using ACO's spec engine would be at advantage. Also, ACO requires a pro-am lineup in the P2 class whereas IMSA allows all-pro lineups. That might be another issue for IMSA teams willing to race at Le Mans.

So, obviously racing at Le Mans wouldn't be so appealing for IMSA teams not using the ACO-spec P2. And the ACO-spec P2 with pro-am lineup wouldn't probably be winning against manufacturer-supported P2s with all-pro lineups in the Tudor Championship. How I would do it would be to split IMSA's Prototype class into two: Pro and Pro-Am classes. The Pro-Am class would use the ACO-spec P2s and those Pro-Am teams could get an invitation to Le Mans. In the Pro class, teams would be allowed (but not mandated) to use car manufacturers' engines and bodykits. If the car count is sufficient, then Pro-Am P2 could replace the Pro-Am PC class.

In my opinion that would be the sensible solution given ACO's and IMSA's differing needs for P2. IMSA needs manufacturers to their Prototype class and ACO doesn't want them to P2. A Pro-Am P2 class in IMSA would be an American route to Le Mans for privateer P2 teams. The Pro class would keep manufacturer involvement in IMSA's top class. And if the Pro class were based on the P2 chassis, the ACO-spec Pro-Am cars might be reasonably competitive against them.

Porsche win the 2015 24 Hours of Le Mans

Porsche have won the 2015 24 Hours of Le Mans. The winning no. 19 car was driven by Earl Bamber, Nico Hülkenberg, and Nick Tandy. Porsche also got the second place with the no. 17 car driven by Timo Bernhard, Brendon Hartley, and Mark Webber. The third place went to the dominant manufacturer of this century, Audi, with their no. 7 car, driven by the defending winners Marcel Fässler, André Lotterer, and Benoit Tréluyer.

Porsche were the dominant team in the qualifying but so were they also in the previous WEC rounds at Silverstone and Spa with Audi still winning the races. Being able to do quadruple stints with the same tyres was helping Audi but they were also facing some adversity. The #7 lost time early in the race when a slow puncture forced them to pit for full service at the beginning of the fourth stint on the same tyres. The #8 Audi lost lots of time when it damaged its front after losing control in a confusing incident with a GT Ferrari when some cars were obviously slowing down for a yellow zone. The safety car periods in Saturday evening gave the #17 Porsche a lead of over a minute, thanks to it having been in an earlier safety car queue compared to its rivals. Like in the previous WEC rounds of this season, Audi again had great race pace. Filipe Albuquerque in the #9 Audi was setting great lap times in the Saturday evening, breaking the old race lap record.

I think the race got decided in late Saturday evening after a safety car period that packed the leading cars. The #17 Porsche that had long been leading got a one-minute penalty for ignoring yellows. And as the #18 Porsche had a couple of incidents under braking to Mulsanne, it was the #19 Porsche racing against the #9 and #7 Audis in the lead. While being soft on tyres had helped Audi to make their tyres last longer, it was hurting them at night when Porsche got their tyres work better and Nick Tandy in the #19 was building a great gap in his stint.

Of course, Porsche's advantage in colder conditions was going to end after the night but I think the gap the #19 built at night would've been enough for them even if the Audis had a clean finish to the race. But the Audis didn't have. The #7 of the defending winners was again Audi's strongest contender in the Sunday morning but then its engine cover blew off and the time spent repairing it cost it the chance to race for win or even for the second place. And the other Audi in the lead battle, the #9, had issues with its hybrid systems so the win was pretty much decided before the final hours of the race, Porsche just had to bring their cars home for a 1-2 win.

Audi may have had the faster car in the race; its three cars were the only ones to go under 3:18 in lap times. But most of the time Porsche was controlling the race and maybe didn't need to go all-out in the race. Last year's WEC champions Toyota have been disappointing this year and they were far from winning pace at Le Mans, finishing 6th and 8th and couldn't have a lap under 3:20 in the race. Their budget is behind Audi and Porsche and that's why they fielded only two cars at Le Mans and possibly the smaller budget can also be seen from their performance this year. Toyota have already announced they will be switching from 6MJ to 8MJ hybrid system subclass for the next year and replace supercapacitors with batteries like Porsche does. I wonder what Audi will be doing as they are currently in the 4MJ subclass, using a flywheel.

Formula One driver Nico Hülkenberg was one of the winning Porsche drivers. He became the first active F1 driver since 1991 and Bertrand Gachot and Johnny Herbert to win at Le Mans. I think an F1 driver winning is great for the race, even though I have also seen opposite opinions fearing this to make the WEC look weak in comparison to F1. While some of the pay drivers in F1 would never become factory drivers in the WEC, you can't deny most of the world's best drivers are in F1 and it's great for the WEC to get them to do even one race. Hülkenberg winning doesn't mean the WEC drivers are bad drivers but it shows the world's best drivers want to do Le Mans. I like seeing IndyCar drivers like Bourdais or Dixon doing American endurance events and similarly I'd like more F1 and also IndyCar drivers joining WEC regulars for Le Mans. Unfortunately, if an F1 team is representing a manufacturer, it is hard to race for another manufacturer at Le Mans. That obviously prevented McLaren-Honda's Fernando Alonso driving for Porsche at Le Mans.

My report of the 2014 24 Hours of Le Mans

This year's 24 Hours of Le Mans is now behind. For me this was the second Le Mans I really followed. I followed as much of last year's race as possible and enjoyed it, and this time I wanted to see the entire race, and it was a truly great race.

This year marked the return of the works Porsche team to Le Mans. I was happy to see Porsche going to Le Mans; they are such an iconic brand in racing and one of my favourite car brands. I really hope they will have success at Le Mans, yet this year I was actually hoping them not to win. I didn't want them to humiliate Audi and Toyota in the first year after their comeback, especially as Audi is another of my favourite brands.

Audi has dominated Le Mans since 2000 winning all but two races, 2003 and 2009. That's why it is understandable many people wanted to have a new winner. Still, my sympathies were on Audi's side, partly because of their difficult week. The #1 Audi R18 driven by Loic Duval crashed badly in Wednesday's practice session. Duval didn't injure himself badly in the accident but was he had to miss the race and was replaced by Marc Gene. The #1 Audi also couldn't participate the first qualifying session on Wednesday. The qualifying wasn't too good for other Audis, too. The three R18s occupied the starting positions 5 to 7, behind the Toyotas and the Porsches.

Early in the race, #14 Porsche had some fuel system problems that forced it to pits being repaired. Then, with just under two hours of racing, it started to rain heavily and we had some drama. The #8 Toyota driven by Nicolas Lapierre seemed to spin by itself to barriers on the wet track, and at the same a GT Ferrari, driven by Sam Bird hit the #3 Audi driven by Marco Bonanomi. The Audi had to retire whereas the Toyota was able to continue the race but lost lots of time being repaired.

At night, the #1 Audi had to pit to get the fuel injector changed. Also the #14 Porsche faced again problems, being forced to have again a long pit stop. Meanwhile the #7 Toyota was racing with a comfortable lead of almost two minutes to the second-placed #2 Audi. Then, in early morning we had the most dramatic moment of the race. The leading #7 Toyota had been reported to have stopped at Arnage and the #2 Audi took the lead. An electrical problem had forced the Toyota to retire from the lead.

Now, despite all the struggles of the week, the Audi team found themselves having a one-two lead in the race with #2 in the lead and #1 second. The #20 Porsche was on the third place in front of the #8 Toyota and #14 Porsche who had lost lots of time in pits during the race. But the race was far from over, there was still more than the duration of a regular WEC race to finish. And it wasn't a comfortable finish for Audi. The #2 R18 dropped to third position because its turbocharger had to be changed. Now the #1 Audi was leading the race, after being heavily crashed on Wednesday's practice. One of its drivers was the record-winner of Le Mans, Tom Kristensen, aiming for his tenth win.

But nothing was predictable in this race. The #1 Audi also had to get its turbocharger changed, which dropped it to the 3rd place. Now the #20 Porsche was leading the comeback race of the manufacturer in Le Mans. But the #2 Audi was coming fast from behind and it got past during the pit stops. Eventually, the #20 Porsche couldn't even make the podium as technical issues forced it to retire. Also the #14 Porsche had to pit because of technical problems but it was sent back to track at the end of the race to cross the finish line.

In the end, the race was won by the #2 Audi R18 driven by Marcel Fässler, Andre Lotterer, and Benoit Treluyer. The #1 Audi R18 driven by Tom Kristensen, Marc Gene, and Lucas Di Grassi finished second and the #8 Toyota TS040 driven by Anthony Davidson, Sebastien Buemi, and Nicolas Lapierre finished third.

Many people must have found yet another Audi win boring but I was happy for them after all the difficulties they had this week. In some ways, I can understand the joy of Rafael Nadal's fans after his maybe the worst French Open-winning performance. In both cases, the old winner was vulnerable but nobody else had what it takes to win.

At the same time, I feel gutted for Toyota. They did everything right in the race but to win a 24-hour race, you must have the reliability and they didn't have. They were the fastest car this year and I hope they can win Le Mans soon, even though Toyota doesn't raise the same passion in me as Porsche or Audi.

Porsche had an excellent comeback race even though technical issues ended it. Before those issues, they had even one car racing for the win. I hope and believe they can have success in the next years and have tight battles for wins against other teams. While I was happy that Audi could win after the difficult week, I hope to get a new winning manufacturer as soon as possible. Despite Audi's win, at least this year the battle for the win involved three teams, so you can't say Audi winning was inevitable.

Besides the LMP1 class, I enjoyed the GTE classes. Especially the battle for the win of GTE Pro was exciting with wheel-to-wheel racing. The #51 Ferrari of AF Corse, #97 Aston Martin, and #74 Chevrolet Corvette were battling for the win of GTE Pro. Unfortunately first the #74 Corvette and then the #97 Aston Martin faced technical problems, ending the battle for the win before the race ended. I wanted Aston Martin to have a good result as their last Le Mans was a sad race because of Allan Simonsen's death in the GTE Am class. That's why I was really gutted about the power steering issue that took them off from battling for the GTE Pro class win. Every cloud has a silver lining, though. My countryman Toni Vilander was driving the winning AF Corse #51 Ferrari with Gianmaria Bruni and Giancarlo Fisichella. And Aston Martin could win the GTE Am class with the #95 V8 Vantage GTE; the same number that Simonsen had at last year's Le Mans. Unfortunately their #98 V8 Vantage GTE faced some technical issues while leading the GTE Am class; otherwise they could have had one-two in the class.

I really enjoyed the race, 24 hours of great racing and drama, and no artificial gimmicks like DRS or tyres designed to degrade like in F1. Le Mans and other WEC races aren't so hard to follow for an F1 fan, as there are many F1 drivers there. My motorsport interest is definitely moving from F1 to Le Mans and the WEC.
