Audi RS7 Sportback (2013) first official pictures

This is the new Audi RS7 Sportback, just unveiled at the 2013 Detroit auto show. It's an A7 Sportback given the hardcore RS treatment, meaning a 552bhp and 516lb ft 4.0-litre bi-turbo V8 that will sprint the RS7 to 62mph in 3.9sec. That's faster than the latest Porsche 911 – it seems life just got a bit harder for the Mercedes CLS63 AMG and BMW M6 Gran Coupe.

VW Golf GTI priced from £25,845 in UK

The new Mk7 VW Golf GTI is now on sale in the UK priced from £25,845. That's only a £195 rise over the old Mk6 Golf GTI, despite the extra power, performance, and a 2.2mpg improvement in economy. Hang on - nearly £26k for a VW Golf GTI is a bit steep, isn't it?  Actually, it's better value than the old Mk6 Golf GTI. For a start, the new Mk7 Golf GTI's 29E insurance group rating is five groups lower than the old model's, so you should save on premium renewals as well as road tax and fuel fill-ups.

New Range Rover & 2014 Range Rover Sport diesel hybrid at Frankfurt 2013

But Land Rover did tell us the 4.4 litre TDV8 will be joining the range later in the year and that a diesel-electric hybrid would be on offer too. And now we know that the diesel hybrid Range Rover Sport – and a Range Rover Hybrid – will both debut at the Frankfurt Motor Show in September. Stuart Frith, LR’s head programme engineer for the new RRS, has confirmed to Car Sales in Australia that the hybrid Range Rover and Sport will arrive in September – as will the TDV8 RRS – but that the 2.0 litre EcoBoost petrol engine for the RRS is still a way off, even though Land Rover are already running it and believe it still offers all a real Range Rover Sport should.
