2012 Jaguar XK debuts at New York +video

The gently tweaked 2012 Jaguar XK It’s not as big an overhaul as the 2012 Jaguar XF, but Jaguar has sensibly had a play to freshen up the XK and keep it looking crisp for a while longer, rolling out the 2012 Jaguar XK at the New York Motor Show. Changes to the XK for 2012 are pretty much as we predicted, although not quite as close to the Jaguar XKR-S as we’d thought likely. The main change on the nose is the arrival of the new headlights we saw on the XKR-S with integrated LED running lights.

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.

In fact everyone, from Ferrari to Rolls Royce, will do pretty much whatever you want to your new car if your pockets are deep enough, and it’s a game – and a cash cow – McLaren are keen to make the most of. That’s why we had the extreme McLaren X-1 project a couple of years ago, but that went a lot further than most Mclaren buyers want to go with their new car.
