Future products: Bentley reskins Continentals, works on convertibles

Bentley's sales have plummeted as its cars aged and the economy fell into recession. The launch of the Mulsanne flagship this year is cause for optimism, as is the coming reskin of the Continental range, which was introduced in the United States in 2005. Bentley will begin rolling out the new versions of the Continental next year, starting with the GT coupe.

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.

Subaru Stella Plug-in Electric Car (EV)

The Subaru Stella Plug-in EV goes on sale in Japan today Not designed to be anything other than a city car, the Subaru Stella has a range of around 55 miles on a full charge of its Li-ion batteries, which can be charged in about five hours from a standard socket (or in 15 minutes from a quick-charge outlet), and a has top speed of 62mph – so it really is a city-only car. Based on Subaru’s existing Stella mini-car the Stella EV is powered by a 60bhp (47kw) electric motor that delivers 125lb/ft of torque from the off. It also incorporates a regeneration system that tops up the batteries during deceleration to help the range.
