Guys why are you being so specific? I totally expect any implementation, should we be so lucky, would be a fictional car. I understand that some people would prefer roof over open pit, but at the end of the day any prototype car would fill the void in LFS at the moment. Diesel, roof, lmp1, lmp2, r10, r8, radical, toyota, porsche, it doesn't matter! Anything eric would build would be a complete hybrid anyway, and tweaked to suit the sim, not a real-life counterpart.
