John Hennessey unwinds modified Chevy SS

Perhaps it's not as impressive as John Hennessey's recent 200mph blast down Houston's new Grand Parkway in a warmed-up Stingray, but we figured we'd show you his latest run down the same road in a Chevrolet SS equipped with his company's HPE600 Supercharged package. Thanks to GM's engineers, the four-door hits its top speed of 163 in 5th, rather than 6th, but what impressed us the most was watching the numbers climb on the VBOX — the car pulls John-Bonham-hard all the way up to its top speed. Hennessey hasn't released details of the mods performed on the SS yet, but we're anxious to see what this anodyne-looking monster will do on the top end once the gearing nag's sent off to the glue factory.

BMW X6

BMW rolled the dice with the original X6, but soon realized its problem would be lack of production capacity at its plant in Spartanburg, SC than a lack of customers - over 250,000 X6s have found homes since it arrived in 2008. It comes as no surprise that a second-generation model has now arrived, but as much as the first was revolutionary, establishing an entirely new SUV sub-genre, the new X6 appears much more evolutionary. At 4,909mm long, 1,989mm wide and 1,702mm tall, the new car grows by just 34mm in length, 4mm in width and 12mm in height.

Kimi may quit again

KIMI RAIKKONEN has revealed he will likely quit Formula One again once his current deal with Ferrari expires at the end of 2015. Raikkonen dropped the bombshell at Silverstone ahead of the British Grand Prix this weekend, and just eight races into his second coming at Ferrari which has so far been a bitter disappointment. Struggling with a car not to his liking, the hotly-anticipated scrap with team-mate Fernando Alonso has failed to materialise as the Spaniard has comfortably out-qualified and out-raced the Finn.
