One Lap of the Web: A Miata ninja, classic race cars and the world's most vintage-car-friendly city

We spend a lot of time on the Internet -- pretty much whenever we're not driving, writing about or working on cars. Since there's more out there than we'd ever be able to cover, here's our daily digest of car stuff on the Web you may not otherwise have heard about. -- If you (or your children) love the smartphone and tablet app Fruit Ninja, you will get a kick out of Motor Authority's photo gallery from the Donington Historic Festival.

Mercedes S65 AMG (2013) first official pictures

By Ollie Kew First Official Pictures 08 November 2013 08:01 Bring on the ‘too much is never enough’ comments: this is the new Mercedes S65 AMG – the top dog of the S-class range. Set to be more than twice as expensive as an entry-level S350 BlueTec, which starts at £62k, the S65 AMG borrows its powerplant from the SL65 AMG, and comes close to embarrassing the SLS supercar in a drag race. Whereas the new S63 makes do with a piffling 5.5-litre biturbo V8 developing 577bhp, the S65 squeezes in a twin-blown V12 good for 621bhp – that’s only one horse fewer than the Mercedes SLS Black Series manages.

Citroen C4 Cactus revealed in production guise ahead of Geneva Motor Show Debut

The Citroen C4 Cactus (pictured) revealed in production spec The Citroen C4 Cactus could probably not have been conceived by anyone other than the French, and the concept we saw at Frankfurt last year was certainly original. Now, Citroen are putting the C4 Cactus in to production and, surprisingly, not a huge amount has changed from the concept. That means the C4 Cactus – with a wheelbase the same as a C4 but with a footprint more the size of a supermini – weighs in at just 980kg, so even though its engines are small and frugal it will have acceptable performance.
