Check out the 1,360-hp heart of the Koenigsegg One:1

The wild Koenigsegg One:1 showed up on our radars late last year before it appeared at the Geneva motor show in March. The latest piece of machinery from company founder--and Michael-Chiklis lookalike--Christian von Koenigsegg delivers one horsepower per kilogram, hence the name. That means 1,360 hp and 737 lb-ft of torque with a 3,000-pound curb weight.

Frankfurt 2011: New Vauxhall Astra GTC (2012) debut

Vauxhall Astra GTC finally arrives at Frankfurt The Vauxhall Astra GTC (and its European equivalent Opel GTC) finally gets to go on public view at Frankfurt this week, a year after it arrived as a concept at Paris. Based on the more prosaic five-door Astra, the GTC carries over just about nothing except the door handles although it still conspires to look like a slightly squashed, butch version of its sibling. The Astra GTC is a decent looking effort from Vauxhall – as is the regular Astra – designed to take the fight to cars like the Scirroco.

New BMW 4-Series shows its sporty side with M Performance add-ons

The BMW 4 Series M Performance Parts have been revealed (pictured) The new BMW 4-Series Coupe may not have arrived in BMW showrooms yet, but that hasn’t stopped BMW showcasing how you can spend extra money on your new 4-Series with a range of M Performance accessories. So when you do go and spec up your new 4-Series you’ll also be able to tick some of the boxes on the M Performance Accessories list for your dealer to fit when your car arrives for delivery and (almost) turn it in to an imitation M4 Coupe if you wish. Probably the biggest seller will be the showy stuff, like the M-Performance body kit which adds a lower front bumper with carbon fibre splitter and bigger air intakes, bigger sills, new back bumper with diffuser and ducts, carbon fibre spoiler at the back, dark chrome trim and carbon fibre door mirror caps.
