Mercedes AMG C 63 price & specs – costs from £59,795

Mercedes AMG C 63 price & specs – costs from £59,795 The pinnacle of the new Mercedes C-Class range – the Mercedes-AMG C 63 – had a reveal last month ahead of its public debut in Paris (and got a new name, with ‘AMG’ hyphenated with Mercedes and in front of the ‘C 63′ bit instead of after) and it’s now gone on sale priced from £59,795 for the C 63 Saloon to £67,745 for the C 63 S Estate. Power comes from a new 4.0 litre twin-turbo V8 developing 469bhp in the C 63 and a more potent 503bhp in the C 63 S, with 0-62mph times of 4.1 seconds for the C 63 (0.1 slower in the estate) and a modest 0.1 quicker in the C 63 S. Not surprisingly, the C63 gets a more than adequate spec including Nappa Leather AMG sports seats, COMAND, mechanical locking rear diff, dynamic engine mounts, unique tracks front and back, upgraded AMG brakes, quad tailpipes, new front wings to cover the wider track, rear spoiler and 18″ alloys.

Do Winter Tyres REALLY work? Oh, yes, say Volvo (+ video)

Volvo prove how effective Winter Tyres are in the Snowdome For some reason, the debate on fitting winter tyres in the UK continues to be a debate, even when those who’ve actually used a car fitted with winter tyres swear by them (an argument not helped by previous government advice). So Volvo – safety conscious as ever – decided to prove the point by taking the very good Volvo V40 off to the Snowdome indoor ski slope in Tamworth to see exactly what difference a set of winter tyres makes to the grip available in a regular, FWD, family Volvo. And the results should make every car owner go out and fit winter tyres.

Gordon Murray Design T27 crash tested

The original Smart car probably did more than its fair share to persuade us that small cars needn't necessarily be unsafe. But now Gordon Murray is on the same mission: to persuade us that his titchy T27 city car is as safe as houses too. Gordon Murray Design has just issued its first crash test results, showing a T27 electric car after a crash test at the UK's MIRA industry research lab.  The crash test in question was the European-standard 40% offset deformable barrier front high-speed impact.
