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.

New Aston Martin V12 Vantage S quicker than Jaguar F-Type V8 S

The new Aston Martin V12 Vantage S (pictured) is Aston’s quickest car At the end of last month, as expected, and following the ending of production of the V12 Vantage, the new Aston Martin V12 Vantage S arrived. Aston proclaimed the new V12 Vantage S as the quickest production car they’d ever built (with the exception of the £1 million One-77) but declined to tell us exactly how quick it was. But now AML have finished playing with their stopwatch and declared the V12 Vantage S will get to 62mph in 3.9 seconds (0-60mph in 3.7s), an improvement of 0.3 seconds on the V12 Vantage and giving the V12 Vantage S the edge over the car we think it should be compared to – the new Jaguar F-Type V8 S.
