Mercedes AMG GT S hits the track in new HD video

The new Mercedes AMG GT S on track at Circuit of Americas The Mercedes AMG GT is the long-awaited replacement in the Mercedes range for the SLS AMG, but even though the new AMG GT (and GT S) offers performance almost the equivalent of the SLS, it’s price tag is a lot lower. In fact, at prices expected to start at around £100,000 – and an extra £10-15k for the GT S version – the new AMG GT is at least a third cheaper than the SLS, and aimed at cars like the Porsche 911 and Jaguar F-Type rather than the stratospheric supercars the SLS had in its sights. That also means Mercedes AMG are going to have to sell a chunk more GTs than they ever did SLS models, so you can expect more promos and more profile for the AMG GT than you’d ever have seen for the modest-run SLS – like the latest Mercedes has just released (below).

Alfa Romeo Mito TCT (2011) comes to the UK

Alfa Romeo's first twin-cluch gearbox is launching in the Mito - and the Mito TCT is now available in the UK. The MultiAir 1.4 is the launch engine for the TCT twin dry clutch transmission. Typically for Alfa, it's technically interesting: Alfa claims it enhances performance and comfort, gives a sportier feel and more importantly in the current climate, reduces CO2 emissions.

Spy Shots: Could this be the 2014 Porsche GT3 RS?

Brenda Priddy & Co. sent us the above photos in an e-mail with the subject line “BREAKING: 2014 911 GT3 UNCAMOUFLAGED!” So, we opened it and found a few shots of Porsche's new rear-engine, mini Panamera in “all black everything” but sporting very little camouflage. If this is indeed the 2014 Porsche 911 GT3 RS, the bodywork is either quite a bit more restrained than that of the outgoing 997.5 GT3 RS, or it's wearing bodywork that won't appear on the 2014 GT3 RS when it debuts at the Paris motor show in September.
