Volkswagen e-Golf goes on sale – price from £30,845

The Volkswagen e-Golf (pictured) is now on sale in the UK The Nissan LEAF has almost had the market place for proper family EVs to itself until recently, but the arrival of the impressive BMW i3 -especially when specced with a range extending motor – threatens to make a dent in LEAF sales, and another dent could come courtesy of the new Volkswagen e-Golf, which goes on sale today in the UK priced from £30,845 (£25,845 after taxpayer bribe). In most of the ways that matters, the e-Golf is a regular Golf MK 7, but lurking under the familiar exterior lies a thumping great bank of batteries weighing 318kg (about the same as a car full of passengers) and an electric motor driving the front wheels and good for 113bhp. Range for the e-Golf is up to 118 miles from a full charge, a charge that will take 13 hours from a regular 3-pin socket, a more acceptable 8 hours if you use the optional 3.6 kW wallbox you can spec (for free from British Gas) and a quick charge of up to 80 per cent in 35 minutes.

Lamborghini Aventador J at 2012 Geneva motor show

There maybe other Italian sports car manufacturers looking to hog the limelight at the 2012 Geneva motor show (and Ferrari and its 730bhp F12 is one of them) but Lamborghini will vie for attention with the Aventador J. A two-seat, open top speedster based on the Aventador LP700-4, it has some intriguing bits of carbonfibre tech and highly individual design. Named 'J' after the FIA’s Appendix J that governs the tech spec of race cars in certain classes, it’s proper bedroom wall material – but little boys and girls are unlikely to ever see it on the road as it’s a one-off and will go to a lucky owner after its appearance at Geneva.
