Land Rover Defender Harris Tweed (2012) prototype

Here's a curious mix of classic Britishness and modern modifications: a Kahn-tuned Land Rover Defender fitted with a butch bodykit, enormous multispoke wheels and knobbly tyres and - inside -tweed-trimmed bucket seats. It's like a Spitfire wearing a Damien Hurst-penned livery. This is, to give the car its full title, the Kahn Defender Concept 17 Wide Body - Harris Tweed Prototype.

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.
