2014 Corvette Stingray rated at 455 hp

The 2014 Chevrolet Corvette Stingray's 6.2-liter LT1 V8 engine has been rated at 455 hp at 6,000 rpm and 460 lb-ft of torque at 4,000 rpm -- the highest standard-power rating ever for the Corvette. An available performance-exhaust system boosts the rating up to 460 hp and 465 lb-ft of torque. Chevrolet says the new LT1 with standard exhaust has 25 more horsepower than the current Corvette's base LS3 6.2-liter engine, which is rated at 430 hp, and 41 lb-ft more torque compared with the 2013 model's 424 lb-ft.

Preview: Porsche Panamera

After what has already been the most drawn-out model introduction ever (the initial Porsche sketches of the new model having been revealed in 2005), Porsche has finally released the first official rendering of its forthcoming Panamera sedan, set to be launched in 2009. Though the plan view doesn't show much of the new Porsche's design, the company says the features will 'include a wide and low body offering dynamic proportions and muscular design'. But while the grand tourer will have a 'compact overall look', the interior space is claimed to offer a brand-new experience of roominess, with two single seats and generous headroom at the rear allowing adults to sit in comfort.

Audi A6 (2011) first official pictures

Essentially an A7 fastback in its work clothes, the new Audi A6 saloon is lighter, greener and more tech-heavy than ever.  The mini-A8 styling is more evolutionary than revolutionary, but underneath the skin are some key key changes, including the addition of a hybrid drivetrain. Initially the A6 comes with a choice of five engines: a pair of petrols and three TDI units. And because all new A6 engines are linked to efficiency-enhancing systems like start-stop and energy recovery the average consumption across the range has been dropped by 19%.
