Audi SQ7- electric turbocharger

To be honest I'm not really bothered about the car (or should that be truck?), but I find the switch to a 48V system and an 'electric turbo' interesting. It seems there are lots of positive advantages so I'm not sure why it has taken so long to happen.

Hopefully Audi will develop a petrol V8 and drop it in a R8 next then expand 48V architecture to the rest of the range soon.

They need a new name for this tech - a turbocharger is a blower driven from the exhaust gases, a supercharger is a blower driven from the crank, perhaps an electrocharger!

Sounds interesting and is an obvious development

Isn't an electric blower technically known as a fan?

Technically, a turbocharger is a gas driven supercharger, so what Audi have is an electric supercharger.

Depending how much power it needs (and the 48V system they've had to design might explain this) surely it's a wonder no one thought of it before. Surely an electric motor is much more energy efficient than the power lost from and engine to run a supercharger.

They are hardly new. One of the guys I used to race against installed a split ram air system to his Caterham with a sealed airbox and he fitted a fan in one of the inlets. He reckoned it resulted in a good improvement in lower speed torque.

Not quite the same as an electric turbo but the same thinking.
