This is the new Porsche 911 GT3 RS 4.0, a 493bhp race car for the road. Think of it as the ultimate 911 – it brings together the brilliant chassis of the GT3 RS, the lightweight secrets learnt on the GT2 RS, and the stonking 4.0-litre six cylinder engine that powers the GT3 RSR racer. This Porsche 911 GT3 RS 4.0 sounds like quite a package… It is, and topping the list of impressive highlights is a new 4.0-litre flat-six engine.

Mercedes S 500 Plug-In Hybrid price & specs – costs from £87,965

The Mercedes S500 Plug-in Hybrid arrives in the UK It’s more than a year since the Mercedes S500 Plug-in Hybrid was revealed, and now it’s finally going on sale in the UK and, if your pockets are deep enough, it offers a perfect ‘cake and eat it’ car. Under the skin there’s a 3.0 litre V6 biturbo delivering 329bhp and an electric motor adding a further 116bhp which together give the S500 Plug-in the ability to blat to 62mph in just 5.2 seconds but return official economy of 100.9 mpg and emissions of a measly 65g/km. That combination means that you won’t have to pay Boris to drive through London, and your BIK rate will be a very modest 5 per cent, making the S500 plug-in Hybrid a perfect choice for every board member in the country currently paying 35 per cent on their petrol S500, BMW 7 Series or Audi A8.

Tomorrow’s world: Fiat's MultiAir engine tech

By Jesse Crosse Motor Industry 14 October 2009 16:50 Fiat this year launches what it claims is a big step forward in variable valve timing: MultiAir. It's the first time that a manufacturer has made a properly variable valve system a production reality, and will slowly be rolled out across most of Fiat's and Alfa's car ranges.How does Fiat's MultiAir vary from existing variable valve timing (VVT) systems?Current VVT systems rely on mechanical systems to open and close the valves. Engineers have long understood the benefits of changing valve opening and closing times to tweak an engine's power and emissions performance, depending on the need for power or parsimony.Valves are an engine's nose and mouth – it inhales through inlet valves and exhales through exhaust valves.
