Audi digs at Mercedes with the help of a pair of Spocks (video)

Audi likes nothing more than a bit of ‘celebrity’ kudos, which is why you’ll find endless celebs (and royalty) running round in Audis thanks to ‘enhanced’ lease deals and freebie cars. But it’s not just individual celebs that Audi loves, they also love a blockbuster film or two, which is why you’ll also see Tony Stark running around in a car with four rings in Iron Man 3 and, although there aren’t many Audis in space (or on the Enterprise), you’ll find Audi pitching in for a bit of PR on the back of the new Star Trek film – Star Trek Into Darkness. Audi has enlisted the services of Mr Spock in the guise of the original (Leonard Nimoy) and the new (Zachary Quinto) to highlight the benefits of driving an Audi, and getting a dig in at Mercedes in the process.

Malaysian Grand Prix: Hamilton quickest in Friday practice as McLaren & Mercedes dominate

McLaren quickest in practice for 2012 Malaysian Grand Prix Lewis Hamilton put the disappointment of Australia behind him to dominate Friday practice for the Malaysian Grand Prix. The opening F1 Grand Prix of the year in Australia last week saw McLaren take an impressive first and third with Jenson Button doing his best Alain Prost imitation to dominate proceedings, with team-mate Hamilton managing third after a poor start. But Hamilton’s grumpy face on the podium in Melbourne said it all – not a start to the new season McLaren’s ‘senior’ driver wanted.

Opel/Vauxhall Cascada [w/gallery]

The Opel/Vauxhall Cascada effectively replaces the Astra Twin Top, but attempts to move the model upmarket as a separate product line. It has moved up a size to reflect its prestige aspirations: at 4,697 mm long and 1,840 mm wide, it's longer than an Audi A5. Like many of the latest generation of convertibles, the Cascada ditches a folding solid hardtop in favor of a lighter, more space-efficient and cheaper soft fabric set-up.
