Audi RS5 TDI Concept gets electric turbo and 380bhp

The Audi RS5 TDI Concept (pictured) gets an electric turbo It’s two years since Audi revealed it was working on an electric turbo to be used in a twin-turbo setup, with the electric turbo able to offer boost pressure from much lower down the rev range than a normal turbo. That has turned in to the Audi RS5 TDI Concept, where Audi has replaced the normal RS5‘s V8 with a 3.0 litre TDI engine with a small electric turbo for low rev work and a bigger turbo to do the higher rev stuff. The electric turbo works from the off to provide maximum torque of 553lb/ft from just 1250rpm, before the bigger normal turbo takes over at 3,000rpm to continue the boost.

It's physics, people.

Audi A3 is the 2014 World Car of the Year

It’s the second time Audi has won the award – the Audi A6 won in 2005 – and probably holds up a mirror to the changing face of the world’s car landscape; more compact, ‘Premium’ cars are now the most favoured buy. But really, the Audi A3 isn’t just a single car.
