Tesla Model S deliveries scheduled

It's been a big day for Elon Musk. First, his company, SpaceX, launched a rocket into space on a mission to resupply the International Space Station.

BMW Z4M? Sorry, it’s the Z4 M-Sport

BMW are testing a Z4 with an M-Sport package round the Nurburgring I suppose that at least this way you can have a Z4 that looks the part- with bigger wheels and bumpers and maybe even a suspension tweak or three – without having to bother with the big price ticket or the not inconsiderable running costs. To be fair, the Z4 sDrive35i is not particularly slow. It will manage to get to 60 mph in around 5.0 seconds; handles well and looks so much better than the Z3 did.

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.
