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.

2012 Mazda CX-5 - Frankfurt Debut Mazda has been touting its SKYACTIV Technologies for some time now, and the new 2012 Mazda CX-5 – which Mazda will debut at Frankfurt next month – is the first Mazda to come endowed with a complete raft of SKYACTIV stuff. The clever stuff includes Mazda’s new modular platform that can be used for everything from the Mazda3 upwards, and which is said to give the CX-5 not just car-like handling but proper sporty and stable driving dynamics too. The SKYACTIV technology comes in to play with the engines too on the CX-5, with the new 2.2 litre diesel delivering 173bhp and a remarkably low 120g/km in standard guise.
