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.

The last punt we had after a tip-off – apart from the XF 2.2 diesel Jaguar denied when we ran the story – was that Jaguar were planning on building an XJ Supersport Diesel. But long before that we heard that, there were rumblings of a more powerful petrol XJ Supersport too, an XJR, perhaps, or maybe an XJR-S or XJ Supersport S.
