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.

Legendary drag racer Don Garlits couldn't have been legendary without his wife Patricia, who recently passed at the age of 71; in a few more weeks, they would have celebrated their 61st wedding anniversary. She supported Don when he didn't think his racing would amount to anything, and she was instrumental in persuading Don to switch to rear-engined dragsters -- Don's eventual acceptance ended up changing the face of drag racing forever.
