Porsche Cayenne gets more power

Porsche Cayenne Turbo - Powerkit adds 40bhp A lack of power is not something you would normally complain about with the Porsche Cayenne Turbo. After all, despite weighing roughly the same as a grouse moor (unlike the previous generation which weighed slightly more than a small moon), it’s 500bhp V8 moves this SUV to 60mph in a chunk less than 5 seconds. But power under the bonnet is addictive, and even if you have 500bhp under your right foot there will always be occasions when you wish you had just that bit more.

Chevrolet reveals more details of Camaro ZL1

The 2012 Chevrolet Camaro ZL1 will not be anywhere near as rare as its 1969 namesake when it arrives during the first quarter of next year, but the most powerful production Camaro to date should deliver performance easily worthy of its model designation. Camaro engineers on Thursday offered media members a preview of the upcoming Ford Mustang Shelby GT500 fighter, and the tale of the tape is impressive, especially in terms of grunt. The 6.2-liter supercharged LSA V8 will make 580 hp at 6,000 rpm and 556 lb-ft of torque at 4,200 rpm, besting Chevy's original targets for the engine's output and bettering its efficiency in the Cadillac CTS-V by 24 hp and 5 lb-ft.

New BMW X5 gets a range of M Performance goodies

The new BMW X5 gets a range of M Performance goodies It wouldn’t be a BMW unless you could make it look like it can go faster, even when it can’t. So it’s good news for buyers of the new BMW X5 that they can opt for the cheapest, and least powerful, X5 sDrive25d and adorn it with enough goodies from the new X5 M Performance option list to make it look like it’d eat an X5 M50d for breakfast. But its not just the lowliest model in the new X5 range that can have any of the new M Performance parts bolted on; BMW will be happy for you to bolt on the extras to anything from the sDrive25d to the xDrive50i.
