Motorcycle helmet integrates head-up display, GPS and rear-view camera

Silicon-Valley start-up Skully Systems will ship its 'world's smartest' motorcycle helmet from next year. It costs $1,399, and draws together a host of technology features that are already becoming familiar to car drivers and makes them available to motorcyclists for the first time. The helmet's visor features the firm's 'Synapse' see-through head-up display system that shows information like navigation data, bike speed, and a 180-degree angle feed from the rear-view camera mounted on the back of the helmet.

Chevrolet Volt prices announced

GM has revealed that the Volt hybrid could cost $33,500 (£21,000) in the US after government tax credits, making it nearly £2000 cheaper than Nissan’s Leaf electric car. The Volt’s List price is $41,000 (£26,300) but qualifies for a subsidy thanks to its low emissions. A basic Volt comes with Bluetooth and sat-nav but buyers can add leather seats and steering wheel, heated seats, rear camera, polished wheels and park assist.

Audi TT Sportback concept – it’s a 5-door TT: Paris 2014

Audi TT Sportback concept – it’s a 5-door TT Audi has long been the master of the niche, so it’s no real surprise they’re looking for ways to ‘extend’ the Audi TT in to a series of new niche models. The latest take is this, the Audi TT Sportback concept, which has arrived at the Paris Motor Show as a big brother to the TT Coupe, with an extra pair of doors and an extra 290mm in length. Audi has also played with the look of the TT Sportback, with a new hexagonal grill, new headlights and a new bumper up front and the new tail lights and smaller back window give the TT Sportback an individual look (well, as individual as an Audi ever gets).
