Porsche 911 GT3 R Hybrid race car revealed

Porsche will bring its latest hybrid know-how to the racetrack in the form of the new 911 GT3 R Hybrid, revealed here for the first time prior to a planned public premiere at the Geneva auto show in early March. Developed by a team of engineers at Porsche's Weissach R&D center, Porsche plans for the stripped-out race car to act as a rolling laboratory. The German carmaker wants to explore the potential of hybrid drivetrains in a racing environment before an expected announcement that it will return to the 24 Hours of Le Mans in a factory capacity, perhaps in 2012, with a race car boasting technology based on that used in the 911 GT3 R Hybrid.

Cadillac CTS Coupe (2010) first pictures

This is the new Cadillac CTS Coupe, a sleek two-door Caddy that will join the CTS line-up alongside the saloon and Sport Wagon estate when US sales start in spring 2010, and take on BMW's 3-series, Audi's A5 and Infiniti's G37 Coupe. It does indeed look like the concept, right down to the twin central exhausts and hidden touch-pad door handles. Yes, there have been some minor tweaks to the front and rear lights and bumpers since we saw the show car at Detroit in 2008, but the overall appearance is pretty similar.

The world's best-selling passenger car is…

UPDATE-Ford announced Tuesday the Focus nameplate sold more than 1,020,000 units in 2012 making it the best-selling passenger car in the world. Data supporting the claim came from Polk's annual vehicle-registration review, which, since it accounts for data from around the globe, comes out three to four months later than other 2012 recap results. In China, registrations for Focus vehicles were up 51 percent, accounting for nearly one in four global Focus sales, according to Polk.
