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.

The Morris Ital - one of Morris Ital by Giorgetto Giugiaro's greatest (sort of) It’s probably a fair bet – or at least was and has been for some time – that Volkswagen would be in the frame to buy an motoring asset that comes on the market. Especially if that asset is in trouble and an iconic name can be grabbed for a song – or less.

Carbon-fiber parts and a software fix help create a lighter, faster Fiat

Chrysler Group's Mopar parts brand and Italian supplier Magneti Marelli have teamed up on a design exercise based on the 2012 Fiat 500 Abarth that shaved weight and added horsepower. The vehicle, called the Venom, has a number of carbon fiber components -- hood and side mirrors, for example -- that makes it about 200 pounds lighter than the 2,512-pound Abarth. The Venom uses software updates and additional exhaust components to boost the Abarth's standard 160-hp 1.4-liter turbocharged engine's output by as much as 25 percent.
