Audi A3 Sportback e-tron price and specs – costs £34,950

Audi A3 Sportback e-tron (pictured) costs £34,950 If governments are going to base car taxation on Co2 emissions, then car makers are going to build cars that ‘game’ the official tests. A perfect example of which is the new Audi A3 Sportback e-tron plug-in hybrid. It’s expensive at £34,950 (although the government bribe for plug-ins does drop the price you pay to £29,950), but thanks to its ‘up to 31 miles’ range on battery power only it comes complete with official economy of 176.6 mpg and emissions of 37g/km.

Bugatti Veyron: A Quest For Perfection

It's easy to run out of superlatives when describing the Bugatti Veyron. Eclipsing every road car before it in terms of power, speed and price, it has been the benchmark supercar for almost a decade. ‘A Quest for Perfection – The Story of the Greatest Car in the World' by Martin Roach is a new book written in light of this redefinition of the supercar paradigm.

2013 Bentley Continental GT Speed Convertible: First Photos

We have the first photos of the 2013 Bentley Continental GT Speed Convertible ahead of a reveal at the 2013 Detroit Auto Show. Bentley hasn’t done the official reveal for the GT Sports Convertible yet, so all we have are the first photos in all their purpleness (although the DVLA thinks this particular Bentley is black). Under the skin we expect the same W12 with 616bhp and 590lb/ft of torque which is enough, certainly in the tin-top GT Speed, to get the monster Bentley to 62mph in 4.2 seconds and on to 205mph.
