Should IMSA split the prototype class?

Should IMSA align the top class with the FIA WEC

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.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.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.
