What can give 202 HP, 300+ ft.lb., AND 39 MPG?

Opel Twin-Turbo Diesel

This is not a revolutionary design concept. It's evolutionary, and doable with minimal changes in the industry.

I'd love to see them scale it down even further for small vehicles.

I never understood how stupid turbo diesel engineers are in trying to solve the turbo lag problem.

At low rpm when the driver floors the accelerator, the turbo effect is slow to kick in, aka, the so called turbo lag.

Using belt driven supercharger is parasitic, sez the engineers.

The solution is so simple.

When the driver floors the accelerator, detect this using a computer system and then use the car battery powered electric motor supercharger to instantly compress the input air flow.

When the rpm of the engine goes up, gradually turn off the electric motor supercharger as the turbo compressor kicks in.

Turbo lag problem solved. Simple. As for charging up the car battery, you can use regenerative braking system.
