Porsche reveals extreme 911 GT2 RS

Porsche has revealed its most powerful and arguably most extreme road-going 911 to date: the GT2 RS. The new rear-wheel-drive road rocket will debut publicly at the Moscow auto show in late August and will go on sale in the United States in October. The GT2 RS, to be built in a limited run of 500, is powered by the latest evolution of Zuffenhausen's 3.6-liter, twin-turbocharged, horizontally opposed six-cylinder engine, tuned to deliver a Le Mans-grade 620 hp.

BMW i3 EV: More than 8,000 ordered already

The BMW i3 EV already has 8k orders BMW has invested heavily in their new ‘i’ range of electric cars – as much as £2 billion it’s estimated – with the ‘i’ cars being developed from scratch rather than based on an existing BMW model. The first BMW i to be launched is the compact city car BMW i3, revealed in production form in July, which costs from around £30k for the regular EV and an extra 10 per cent for the i3 with a range extender engine. Despite being revealed in July BMW has not yet officially put the i3 on sale, but that hasn’t stopped potential buyers lining up to palce a reservation, with more than 8,000 already signed-up for an i3.

Concept Car of the Week: Saab Aero X

In January 2005 Bryan Nesbitt, then-executive director of GM Europe Design, charged the 15-strong Saab Advanced design team in Gothenburg, Sweden, to create the "ultimate vision of the brand". The design team – led by head of Advanced Design at Saab, Anthony Lo – worked on a number of sports car proposals, which were considered 'the jet fighters of the road.' The chosen proposal by Alex Daniel was for a large, front-engined sports car that would become one of the most universally acclaimed concept cars of recent times. Of course the Aero X's door arrangement – complete with huge, forward-hinged canopy – is its party trick, but even without the theatrics the car's proportions, surfacing and graphics are exceptional.
