The Harvey brothers dominated autocross in an obsolete Datsun a couple decades ago.
Who could forget this solid dime of a concept?
The idea was for it to have a nearly 200hp electric motor for each wheel and power came from a battery and a pair of onboard mini-turbines. I think those turbines were chosen more for artistic reasons than anything else, they did have their inlets open to the cabin after all. A prototype was built that used a heavily modified and even more heavily boosted EcoBoost I4 instead and had one electric motor per axle.
But the original concept was actually just one very slight change from a brilliant and practical setup. Off-the-shelf batteries are still heavy and expensive. Turbines are light and used aircraft units that are no longer fit to fly on paper are...less expensive. And they're much lighter on fuel than an ICE under constant load conditions. I'm surprised nobody's tried an AWD electric supercar with a small battery pack and a used aircraft turbine or maybe an aircraft APU for power. It makes a lot of sense right now. the Koenigsegg Regera has come close, I wouldn't be surprised if the next top-of-the-line Koenigsegg uses this setup.
I loved the idea of that concept with the microturbines. It does make a lot of sense. Maybe pair them with a supercap for rapid extraction of energy.
Supercaps and EVs are like chocolate and peanut butter! One just for compensating for turbine lag (in both directions) would be a great idea.
How are we not obsessed with the fact that Le Mans cars now have four digit horsepower levels thanks to their hybrid systems? I think it was Toyota that was basically planning to have so much power on tap that they'd be impossible to pass, and they were bragging about the energy recovery speed of the supercaps.
Because nearly all of us hear 'hybrids' and think...
The Le Mans P1 cars are amazing no two ways about it.
Thread resurrection: This kind of powertrain is now being tried in a series-hybrid semi truck:
