Audi Quattro concept (2013) at Frankfurt motor show

This is our first look at Audi’s new Quattro concept, the latest evolution of Ingolstadt’s plot to build a flagship super-coupe inspired by its Eighties all-wheel drive icon. However, it doesn’t just look a whole lot more aggressive than the original 2010 Quattro concept – it’s also massively punchier under the skin. What’s new exterior-wise for the 2013 Audi Quattro concept?

Infiniti Q50 Eau Rouge would get over 500bhp

Infiniti Q50 Eau Rouge would get over 500bhp The Infiniti Q50 Eau Rouge Concept was actually revealed in photos by Infiniti 10 days ago, but now it’s had a proper Detroit reveal and, although just a concept, it offers promise. Yes, the Q50 Eau Rouge is about Infiniti cashing some of the kudos they get from sponsoring Red Bull, so we get lots about the Q50 being inspired by F1, F 1 flappy paddles, F1 aerodynamics… But the fact is that the Q50 Eau Rouge does look promising and Infiniti has made a decent fist of adding go faster bits and bobs – including carbon fibre, inside and out – without making the Q50 look silly. But what’s most interesting is that the Q50 Eau Rouge perhaps has the potential to tackle cars like the Mercedes E63 and the BMW M5 if, and it’s still an if, it goes in to production.

Jaguar reveals 'brand-new' Lightweight E-Type

This is a brand-new Lightweight Jaguar E-Type, exactly as it would have been if it had left the Browns Lane factory gates in Coventry way back in 1963. It’s not a restoration, either, but a totally fresh, zero miles car that will make its world debut later this week at the Pebble Beach Councours d’Elegance 2014. Back in May, Jaguar announced that it would finally build the remaining six "missing" Lightweight E-Types (originally developed for racing) that it never got round to in the 60s – now they’re here.
