McLaren P1 tests in Arctic, MP4-12C at drag strip

McLaren has produced less than a handful of road cars in its 50-year existence, and they've all been hits. The company currently sells two cars for the street: the P1 and the MP4-12C, and they both require the “super” moniker. The McLaren P1 made its debut at the Paris motor show in September, and has been the subject of many analyses ever since.

Mercedes GLA Concept: OFFICIAL

Aimed at cars like the BMW X1 and Audi Q3, the GLA is a good-looking compact SUV that carries much of what’s good about the new A-Class, raises its ride height, adds a few butch bits and creates a car that will probably have more appeal for owners of the old A-Class than the new A-Class does. The GLA heading for the Shanghai Motor Show sports a 2.0 litre turbo with 208bp, 4MATIC and a 7G-DCT gearbox – which we guess makes it a GLA 250 – and sports something new – laser headlights that function as projectors. The GLA features a pair of cameras on the front of the roof rails that can take 3D HD images and can be removed if you want to use them for mountain biking or jet-skiing or whatever floats your sporty boat.

Chancellor to ‘freeze fuel duty’ until 2015?

The chancellor of the exchequer, George Osborne, has announced that fuel duty will be frozen until 2015 – if the savings can be found to pay for it. The announcement came during a speech at the Conservative party conference, in which George Osborne said: “Provided we can find the savings to pay for it, I want to freeze fuel duty for the rest of this parliament.” The 2p-a-litre rise planned by the Labour government for September 2014 would be cancelled, continuing a freeze that has lasted two-and-a-half years already. But this is conditional on the treasury finding the funds to cover it.
