Mercedes start the tease for the 2014 S63 AMG

Mercedes are teasing the arrival of the new S63 AMG (pictured) The 2014 Mercedes S Class has already made its debut, at least in ‘standard’ guise, but there’s a lot more to come. There’s the S-Class Coupe – which will replace the current CL – and there’s the new S-Class Pullman – which will replace the Maybach. But the next instalment for the new S-Class will be the performance S63 AMG, which we’re expecting to arrive at Frankfurt in a couple of months, and ahead of that Mercedes is starting to tease its arrival.

The European Institute of Design (IED) in Turin will unveil its new Gloria concept, developed in collaboration with Alfa Romeo Style Center, at next month's Geneva motor show. These renders of the sports sedan concept, which is 4,200mm long, 1,920mm wide, 1,320mm high sitting on a wheelbase of 2,900mm, show a traditional Alfa grille that feeds into the hood's prominent V-shaped character lines. Two leather hood straps in front of the windshield are a nod to the brand's older models.

New Porsche 911 GT3 (991) technical highlights (video)

Ahead of its arrival with customers, Porsche has delivered a new video of the GT3 designed to make it clear just how some of its technical highlights work to make the GT3 swifter and more nimble than ever before. Power is of course the key to the GT3 – 468bhp and 324lb/ft of torque – but the power is no good unless the GT3 can put that power down as efficiently as possible in all circumstances. Porsche assert that the GT3′s chassis is engineered for Motorsport, and key elements of the new GT3 make it even more able.
