We still don't know the details about the engine. Even if it's a turbo V6 I still think the engine block, and rods should be standardized, let the manufacturers figure out the heads crank and pistons, and the lower block. Standardize the cam phasing mechanism and allow variable timing,but no variable lift profiles. Variable geometry turbo and exhaust. Standardized pneumatic valve system. This along with chopping the MGU-H should make the engines substantially cheaper, but still allow the manufacturers to put their own take on the concept. The engine should make roughly ~730hp or like the old V8 engines, the hybrid system should be good for 200+kw. Deployment and recovery should be controlled by the driver, the rate of both deployment and recovery should be variable.
One way would be to have two wheel mounted triggers which deploy through the front wheels. Or a push to pass with different settings, and a BBW which harvests at the rate the driver selects if the plan is to keep it RWD.
The height of cultivation is really nothing special. It is merely simplicity; the ability to express the utmost with the minimum. Mr.Lee
