Mercedes S-Class Plug-in Hybrid revealed for Frankfurt 2013

We’ve driven the new 2013 Mercedes-Benz S-Class already this year (and loved it), but now the ‘best car in the world’ has added another feather to its cap. The German firm has released details of a super-high efficiency version of its S-Class saloon called the S500 Plug-in Hybrid, ahead of the car’s debut at the 2013 Frankfurt Motor Show next month. It goes on sale in the UK in 2014, and its vital statistics are absolutely astonishing.

New BMW 3-series bows, performance-oriented 335iS joins the lineup

A new performance-oriented 335iS model endowed with an M-sport styling kit and unique chassis settings heads the list of changes BMW brings to its facelifted 2011 3-series coupe and convertible. Set to slot into the lineup between an upgraded 335i and the M3 when it goes on sale in March as an exclusive for North America, the 335iS runs a tuned version of BMW's N54 engine, as found in the recently unveiled Z4 sDrive35iS, coupled to either a standard six-speed manual or an optional Getrag-engineered seven-speed dual-clutch gearbox. The twin-turbocharged 3.0-liter inline six-cylinder engine of the 335iS adds a special software package to bump power to 326 hp and lift torque to 332 lb-ft--or to an even gutsier 369 lb-ft for short periods via an overboost function that unleashes added turbocharger boost pressure.
