So which is your greatest performance car?

CAR took eight of 2010's best sports cars to France to test for the best in our Performance Car Of The Year test. After six days, 2500 miles and much toil (honestly), we anointed the Ferrari 458 Italia as the finest performance car of last year. But do you agree with the result?

Mercedes GLA 45 AMG (2014) first official pictures

By Ollie Kew First Official Pictures 07 January 2014 10:00 This is, at last, the Mercedes GLA 45 AMG. We’ve seen Visions of the GLA, and a ghastly stickered-up ‘concept’ version, but this is the surprisingly handsome production version of Merc’s super-crossover. Prices are expected to top £43k, outpunching the Audi RSQ3’s ask, and Merc’s other four-pot rockets, the A45 and CLA 45, which start at £38,190 and £42,265 respectively.

A heavy key chain may deactivate the airbags in your Chevy Cobalt or Pontiac G5

GM is recalling 788,000 Cobalt and Pontiac G5 sedans for a potentially deadly problem with the ignition system. When the vehicles' keys are connected to heavy key chains (or, say, key rings laden with a dozen extra keys), a sufficiently extreme jolt or impact could shift the ignition out of the "run" position and into the "off" position. Cuts electrical power to the vehicles' systems, in turn deactivating the airbags.
