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.

New Hyundai Test Centre at the Nurburgring revealed

Hyundai’s new test centre at the Nurburgring If anyone had said, just a few years ago, that Hyundai would develop a test centre at the Nurburgring to help shake-down their cars, they’d have been laughed at. But Hyundai – and Kia – have come so far in recent years that it makes absolute sense for them to develop a full-time testing facility at the Nurburgring to test their cars for the road, along with just about every other car maker of note. James May may object to the Nurburgring factor in the suspension set-ups of many road cars (and we do have some sympathy for his point of view), but the sometimes extreme nature of the Nurburgring’s surfaces – and its endless twists and turns, uphill and down – do offer car makers an easily accessible place to test cars in the (almost) real world.

Citroën Cactus concept with Air Bump technology confirmed for Frankfurt debut [w/Video]

Citroën's Cactus concept featuring a mysterious sounding 'Air Bump' technology will be taking center stage at the carmaker's stand at this year's Frankfurt motor show. The carmaker has released just one image of the concept along with a 21-second video (see left) showing a spongy panel labeled ‘Air Bump' being poked. Although this doesn't really tell us much about what this new technology actually does, we suspect the panels featured in the video are inserted into the bumper and can protect it from the smaller-scale collisions that can happen in everyday life.
