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.

Lexus LFA Nurburgring Edition Laps the ‘Ring in 7:14.64 +video

Lexus LFA Nurburgring sets a Lap Record at the Nordschleife The news that the Lexus LFA Nurburgring has lapped the track after which it is named in a remarkable 7:14.64 will bring a smile to the face of Hiromu Naruse, wherever he may be. Hiromu Naruse was considers by most whose opinion matters to be the ‘Godfather’ of the Japanese performance car’, and devoted most of the last decade of his life to honing and developing the LFA. He lost his life in an LFA Nurburgring Edition in the Summer of 2010 whilst testing the car near the Nurburgring itself, and it’s nice to think that if he’d still been with us, despite his age, it could well have been Naruse-san at the wheel.

2014 BMW M5 facelift leaked – by BMW’s own website

Fortunately, the BMW news specialists at BimmerPost were on the ball and managed to get some screen-grab photos of the new M5 before BMW realised their mistake, so we get to see what BMW has planned for the M5, and probably a guide to what the facelift for the rest of the 5-Series range will offer. The changes aren’t huge, and as far as we can see all that’s going on is a bit of influence from the M6 and 6-Series in general, with a new kidney grill that looks like the 6 Series, and a steering wheel looks like that on the new M6 too, together with the latest iDrive controller. The leaked images don’t tell us what BMW are planning under the bonnet of the facelifted M5, but it’s not too much of a stretch to expect a Competition Package for the M5 to give it similar clout to the new Mercedes E63 AMG S.
