Mercedes at 2013 Goodwood Festival of Speed – includes SLS AMG Black Series debut

The Mercedes SLS AMG Black Series (pictured) debuts at 2013 Goodwood FoS In case you hadn’t noticed, it’s the Goodwood Festival of Speed this weekend and car makers are out in force with their fastest supercars and classics. Mercedes always offer a decent show at Goodwood and this year is no different, with the UK dynamic debut for the Mercedes SLS AMG Black Series, which will be strutting its stuff all weekend up the hillclimb. At the other end of the performance range, the Mercedes A45 AMG is also in action showing the crowds just what 360bhp in a compact hatch can do with its runs up the hillclimb.

AMG Vision Gran Turismo concept shows off ahead of PS3 appearance

Mercedes-Benz has revealed a spectacular new virtual sportscar concept created by its in-house design team for inclusion in Sony's new PlayStation 3 game "Gran Turismo 6." Called the AMG Vision Gran Turismo, the brawny-looking gullwing coupe is to be revealed as a model at the opening of Mercedes-Benz's new research-and-development center in Sunnyvale, Calif., on the eve of next week's LA Auto Show. Yet despite the unveiling in 1:1 scale, the new two-seater is destined to remain a feature of the virtual world as the first in what Mercedes-Benz is billing as a series of Vision Gran Turismo vehicles to be unveiled in the near future. While the virtual properties of the AMG Vision Gran Turismo mean it will only ever see running as a high-resolution graphic within the new "Gran Turismo 6" game, this hasn't deterred Mercedes-Benz from providing it with detailed styling and mechanical data -- elements of which are said to provide solid hints to the upcoming GT AMG due to be unveiled in mid-2014 as a range-topping replacement for the SLS AMG.

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.
