Poll: Would you buy a Hyundai i20?

Last week we asked you if you'd be interested in a Nissan Micra, which is built in Mexico and is available in Canada and dozens of other countries, but not in the U.S. A substantial majority of our readers, 77 percent, voted that they would be interested in buying the $9,100 Micra if it was sold in America, a slightly lower percentage than for most of our past foreign-vehicle polls (which were all quite different, it should be noted). The Micra essentially offers the same engine and almost the same amount of interior space as the Nissan Versa Note at 2/3 the price of a stateside Note, which is already considered to be about as spartan as it gets despite a $14,780 price tag.

Volvo Flywheel KERS Hybrid cuts fuel consumption by 25%

Two years ago we reported that Volvo were testing a clever hybrid Flywheel KERS system for road cars and hoped it would prove to be a good way to make road cars more economical. And it seems it does. The Hybrid Flywheel KERS system Volvo has developed weighs only 6kg, has a diameter of just 20cm, is made of carbon fibre, sits in a vacuum and is located on the back axle and works by recovering energy under braking which is then stored for use when the car moves off.

Paul Walker to be recreated through CGI for 'Fast & Furious 7'

Paul Walker's character will make an appearance in the next "Fast & Furious" film thanks to scenes filmed before his death and computer-generated doubles of the actor. Several sources are reporting that at least four body doubles of Walker have also been involved in the film's ongoing production since filming resumed in late January, after several weeks of evaluations and rewrites by the studio. Approximately half of the photography involving Walker's character, Brian O'Conner, had been shot at the time of Walker's death in Porsche Carrera GT alongside Roger Rodas, his friend and business partner, over Thanksgiving weekend in November of 2013.
