Porsche 911 Turbo (2010) unveiled

By Ben Pulman First Official Pictures 07 August 2009 10:14 This is Porsche’s new 911 Turbo, with an enlarged and twin-turbocharged engine producing more power, plus the option of a twin-clutch gearbox that features proper gearshift paddles. Unbelievably, it’s the first entirely new engine in the 35-year history of the Turbo. Essentially it’s the same direct-injection 3.8-litre flat-six that you’ll find in regular 911s, but now fitted with variable geometry twin turbos to give a healthy 493bhp, a 20bhp increase over the current car.

Mercedes-Benz SL

The next generation Mercedes-Benz SL – code name R231 – is the sixth model to wear the 'Sport Leicht' badge since the first back in 1954. Despite being 50mm longer (at 4612mm) and 57mm wider (1877mm) than its predecessor, the new SL is considerably lighter thanks to its aluminium construction. Its drag Cd figure of 0.27 also helps to increase efficiency.
