2009 Mercedes-Benz S Class

The Mercedes S Class has long been at the forefront of car technology. You can bet your boots that what we see on any new S Class will be where mainstream makers go in years to come. The S Class was first with things like inertia reel belts and air-bags, and the 2009 Mercedes S Class (perhaps we should call it the 2010 Mercedes S Class in deference to our US friends) – although an update rather than new model – follows this tradition.

Honda Micro Commuter Concept

The Honda Micro Commuter Concept is yet another sub-car personal automobility vehicle, adding to the scores presented over the last year.

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.
