Their GT3 cars are gone as well. WEC's new requirement that each manufacturer have a 2-car team + a 2-car GT3 team is making things VERY expensive. Plenty of manufacturers looking to get in though and, eventually, the grid will limit out. Lamborghini may not ever be able to re-enter. Iron Lynx who was running the Huracan GT3s has switched to Mercedes AMG GTs, which allows Mercedes to also run at Le Mans for the first time in many years. Can a M-B Hypercar be far behind?
We've also got Hyundai coming in and McLaren as a near certainty. The Golden Age of endurance racing.
I suppose this is all good for IMSA, as long as they don't implement a 2-car rule.
