2014 Mazda 3 five-door revealed

Mazda has gained a fair amount of traction with its fuel-efficient Skyactiv technology, which was first fully implemented in production on the CX-5 compact crossover, followed by the 2014 Mazda 6 midsize sedan. However, unlike the CX-5 and 6, the Mazda 3, the company's best-selling vehicle, only enjoyed a mild Skyactiv makeover for the 2012 model year with the 2.0-liter Skyactiv engine and transmissions being made available on the second-generation model. This meant the 3 would have to wait until an all-new generation debuted to enjoy the entire suite of Skyactiv equipment, including the lighter-weight chassis, body and suspension.

Video: Fiat creates café racer 500 for SEMA

Fiat is preparing a café racer-style 500 for this week's SEMA show by stripping down an Abarth version to take it "down to the essence of what you need to drive a car." The café racer philosophy of ‘more speed, less comfort' was born around the 1960s British 'biker scene and while initially focussed on increasing performance, quickly developed into a culture as concered with 'the show' as 'the go'. "It takes something like this to really get noticed at SEMA," says Craig Buoncompago, Project Manager at Fiat Product Design. "The Café Racer is really going to be one special car that you guys should really come and see." The 500's roof has been chopped, while also shorn of its door handles and being fitted with hot rod billet rims.
