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.

The Technology Behind F1 Cars: Aerodynamics [w/Video]

Ferrari's latest video in its ‘Discover the technology of Formula 1' YouTube series sees Scuderia Ferrari's deputy design chief Simone Resta focusing on the chassis and side pods' design and its effect on the aerodynamics. This video follows two episodes, the first of which introduced viewers to the concept of aerodynamics – which is the subject of the series' first part – while the second took a look at the design and effect of the car's front wing and nose. The great thing about this series is you don't have to be a genius – or even know your way around an F1 car – to get to grips with the concepts or terminology.
