Red Bull do doughnuts on the Burj Al Arab Helipad to celebrate F1 title (video)

David Coulthard gives the thumbs up whilst doing doughnuts Sebastian Vettel may be cool, collected and composed behind the wheel of his Red Bull F1, but even an in-control German needs to let off steam when he’s just taken his fourth F1 drivers title in a row. So at last week’s Indian Grand Prix, Seb celebrated his title win by producing a series of doughnuts in his car on the finish line, much to the annoyance of FIA officials who fined him €25k for his celebrations. But the latest doughnuts by an F1 team won’t have the FIA up in arms (probably) even if the stunt Red Bull have pulled to mark their latest achievements will give anyone who’s afraid of heights the heebie-jeebies.

Hennessey opens up the LS9-powered Camaro

Hennessey Performance is introducing a convertible version of its limited-edition 2011 HPE700 Camaro. The tuning company will produce just 24 copies of the 2011 HPE700 Camaro, but it hasn't revealed how many will be hardtops or convertibles. “We have already sold several of our 2011 HPE700s in hardtop form, increasing the potential for the convertible LS9 Camaro to become an even rarer option than before,” said John Hennessey, president of Hennessey Performance.

Opel Ampera preview

Opel has released a teaser sketch of its new five-door extended-range electric car ahead of its public debut at the Geneva Auto Show in March. Based on the Voltec powertrain and chassis architecture of Chevrolet's Volt, the Ampera promises to surpass that car in terms of style by some margin. The body appears to be nearly identical between the A- and C-pillars, but the deformed horseshoe-shaped headlamp design and two-bar grille come straight from the 2007 Flextreme concept, as do the car's tree-branch alloy wheels.
