Tomorrow’s world: Fiat's MultiAir engine tech

By Jesse Crosse Motor Industry 14 October 2009 16:50 Fiat this year launches what it claims is a big step forward in variable valve timing: MultiAir. It's the first time that a manufacturer has made a properly variable valve system a production reality, and will slowly be rolled out across most of Fiat's and Alfa's car ranges.How does Fiat's MultiAir vary from existing variable valve timing (VVT) systems?Current VVT systems rely on mechanical systems to open and close the valves. Engineers have long understood the benefits of changing valve opening and closing times to tweak an engine's power and emissions performance, depending on the need for power or parsimony.Valves are an engine's nose and mouth – it inhales through inlet valves and exhales through exhaust valves.

Brabus tunes Mercedes-Benz CLA 45 AMG to 394 hp

It was only a matter of time before German tuning house Brabus looked at the Mercedes-Benz CLA 45 AMG and said: nahh, it's just not powerful enough. Recall that the base CLA 45 AMG already produces 355-hp and 332 lb-ft of torque courtesy of its modestly sized 2.0-liter turbocharged inline-four (an impressive feat by itself, yielding the highest output of any production four-cylinder engine), which gives it the ability to get to 60 mph in just 4.4 seconds. Given its $48,375 price tag for stateside 4Matic all-wheel drive version, many would call that a bargain for the performance stats provided.

Peugeot EX1 electric concept car (2010) first pictures

This is the Peugeot EX1, a two-seat electric roadster concept car built to celebrate the French brand’s 200th anniversary. And the EX1 will let Peugeot usher in its bicentennial in style as it’s just notched up a number of electric car world records. It’s almost entirely carbonfibre, and the rear-hinged doors contain the seats, so you sit on the buckets before swinging your whole body into the metal and leather-lined cockpit.
