Charles Gray one of the heads of the EPA HH program stated he could hold a 500 HP hydraulic motor in my hand.

Easily light enough for an in wheel drive.

A Virginia Tech Engineering school group that studied my design for one year, concluded that an in wheel drive would generate 35 HP per wheel (at the wheel itself) and 380 pounds feet of torque from 0 wheel speed, per wheel.

Thats energy density and high torque from 0 wheel speed with no large battery (read expensive) for storage.

Ths INNAS configuration (previously linked) used engine on operation less than 12% of the test cycle.

Same 0-60 in 8 seconds performance.

Half the fuel consumption

better than 50% reduction in emissions.

Now if you addressed engine design and optimized it for efficiency in the narrow range of BSFC, you could reduce the weight of the pistons and connecting rods, eliminate any throttle control or fuel delivery control, add a heat racovery system to the exhaust to operate the accessories and increase the efficiency. In fact you could use a smaller engine to further increase efficiency.

Reduce the fuel tank capacity to reduce weight.

While electrics could apply that same torque to each wheel, either system could reach the limits of the traction of the tires themselves, so performance becomes a function of actual traction.

Next time you feel like wasting some fuel, do a single panic stop from 60 MPH and measure the distance your car travels.

That same distance (and time) is exactly the same distance you would need to accelerate in a HH to 60 MPH, and only 20% of the energy would be from fuel consumption. The rest would be from the energy you accumulated in the previous stop.
