Those hyper car hybrids are already out there from McLaren, Ferrari, Porsche and a few others.
The McLaren F1 was designed by one of the greatest F1 designers Gordon Murray with an engine designed by one of the greatest engine designers Paul Rosche. They ran an entire GT series in Europe including LeMans and Spa plus others and the engines ran the whole series without a rebuild!
McLaren has a hyper car as does Porsche, Ferrari and one or too others plus Koneiseeg which is noy hybrid. None of these cars could win LeMans in their first run. What is even more amazing is the F1 ran in the GT class which never wins LeMans because they are slower than the prototypes.
Here is the car and the amazing sound of that BMW V-12. I am more a Ferrari V-12 sound guy but this car is amazing. McLaren had more professional teams and this one was thrown together at the last minute and they won it. The main sponsor Ueno Clinic in Japan. They specialize in penis operations. LOL!
One reason why they won was JJ Letho of Finland was driving blindingly fast laps in the rain at night. This car was essentially the road car out of the box. Hypercars would be breaking down by the first 3 hours,.
