Aston Martin DBS Ultimate Edition mooted as run-out special

Aston Martin DBS Ultimate Edition planned The Aston Martin DBS is to be refreshed at the end of 2012 and AML look set to produce a run-out model – the DBS Ultimate Edition. There’s no doubt that Aston Martin likes a variation on a theme, and has a real penchant for a limited edition car whenever a suitable occasion can be found. So a run-out model for the current DBS is a given.

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.

Porsche 911 GT3 R Hybrid at the Nurburgring – Video

The Porsche 911 GT3 R Hybrid Nurburgring video below In February we reported that Porsche has developed the unthinkable – a hybrid 911. But this wasn’t a hybrid 911 with a bank of batteries and a fluffy-bunny conscience, but a rampant track 911 with a great big electro-magnetic flywheel and a KERS-like thump of an extra 160bhp – the Porsche 911 GT3 R Hybrid. The 911 GT3 R uses technology developed by Williams F1 and comprises of a pair of generators in the front wheels that shove energy to a composite flywheel (conveniently located next to the driver – not sure how well that would go down on a road0going version) which is the stored and can be thrown at the back wheels whenever the driver wants, in a way very similar to KERS.
