Mazda 6 (2012) revealed in teaser images

Mazda has released shadowy teaser images of its new 6 saloon, in anticipation of its world premiere at the Moscow motor show, running from 29 August - 9 September 2012. The car's nose is very similar to the Takeri concept of 2011, continuing the new Mazda family face first seen in production trim on the new Mazda CX-5 crossover. The new 2012 Mazda 6: all the details Like the CX-5, the new Mazda 6 will benefit from Mazda's 'SkyActiv' technology. SkyActiv brings a lightweight modular architecture and a range of cleaner petrol and diesel engines – which Mazda claims are nearly as frugal as hybrids without a bulky EV battery in sight.

New Range Rover tows Airstream 684 to Africa – and back

Land Rover has hitched the 2013 Range Rover to the luxurious Airstream 648 and towed it to Africa and back – 3,676 miles in 11 days. But nothing rams home the abilities of a car, even a luxury SUV, like a long-term challenge; the novelty wears off and what is left is the inherent abilities to judge. And it seems Land Rover has managed to demonstrate just how able the new Range Rover is with the sort of towing job few Range Rover owners will ever undertake.

Mercedes A 45 AMG goes off-road in the Desert (video)

The Mercedes A 45 AMG struts its stuff in the desert The Mercedes A 45 AMG is now starting to appear in small numbers on UK roads after buyers have been tempted to shell out nearly £40k for the quickest Mercedes A-Class there’s ever been. But it seems Mercedes don’t want us to think of the A 45 AMG as just a very hot hatch for the roads, but as a little hot hatch with some proper off-road pretensions. So they’ve taken the A 45 AMG off to West Africa to show it at play on the dirt tracks and sand dunes, and we have to say that Mercedes 4MATIC four wheel drive does seem to make a decent fist of coping with what’s thrown at it.
