General Motors will add a structural reinforcement and devices to prevent overfilling of the battery cooling system in the Chevrolet Volt hybrid sedan to prevent the possibility of a fire after a side crash. The changes come seven months after a Volt caught fire three weeks after being crash-tested by the National Highway Traffic Safety Administration. The government agency in November opened a defect investigation into the Volt because of the battery fire.

Ferrari shows next Enzo's HY-KERS V12 at Beijing

Ferrari stole a surprise march at the 2012 Beijing auto show when it announced a few details about its forthcoming Enzo successor. The powertrain you see here is essentially the hybrid supercar architecture which'll underpin the new hypercar being readied for launch later in 2012.

Bonus points for Nico Rosberg chucking a mike around like it's a hacky sack.
