Subaru Impreza WRX STI A-Line released in Japan

To bring its flagship performance sedan to the masses, Subaru has released the Impreza WRX STI A-Line in Japan. The A-Line swaps-in a traditional five-speed automatic transmission with Sportshift in place of the six-speed manual. Paddle shifters and a blipping control system that automatically raise engine revs during downshifts are standard.

Mercedes CLS (2011) first official pictures

After months of speculation and spyshots, we can finally bring you the first pictures of the new 2011 Mercedes CLS. Due to bow in at the Paris motor show in September 2010, the new CLS continues the theme set by the 2003 original, offering four doors in a low-slung, coupé-like shape. If the new Mercedes CLS stirs your memory somewhat, that would be because it draws heavily on the Shooting Break concept which we saw earlier in 2010 at the Beijing motor show.

First look: 2014 BMW M3 and M4

The BMW M3 is back, faster and more powerful than ever before -- but only as a four-door sedan. For its iconic 3-series-based performance model, BMW will dispense with a 26-year tradition of high-revving naturally aspirated engines in lieu of turbocharged six-cylinder power. Revealed here in production-car guise for the first time, the new 425-hp M3 sedan will be joined at the outset by its sister model, the M4 -- a mechanically identical but stylistically sleeker two-door coupe previewed in lightly veiled concept-car form at the Pebble Beach concours in California last August.
