Since it's "supercars" too, how about a Koenigsegg Jesko Attack?
5.0 liter V8 that makes 1280 hp on gas, or 1600 hp on E-85. 8,500 rpm redline. 1,100 ft lbs of torque at max. 9 speed "light speed" transmission. 3,129 lbs curb weight.
If you don't mind a hybrid, and want to take the family, there's the four seater Koenigsegg Gemera. They say there's as much leg room in the back seat as the front:
2,300 combined horsepower between the V-8 and the "Dark Matter" electric motor. All wheel drive.
