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.

McLaren P1 Geneva reveal confirmed & first instrument view

The McLaren P1 supercar has been confirmed for a Geneva Motor Show debut and we get the first peek at the P1′s ‘Race’ instruments. McLaren are certainly making the most of the reveal of the P1 and are still keeping the exact specifications close to their chest, although we do know that the P1 will get a modified version of the V8 in the 12C with a hybrid KERS type boost offering something north of 900bhp. But McLaren has thrown us a titbit of extra information with the Geneva confirmation in the form of two photos of the digital instruments in the P1 (inset above and in the main photo gallery for the P1).
