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.
