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.

Peugeot SxC concept

Peugeot have revealed pictures of its latest concept ahead of its Shanghai launch. Dubbed the SxC, the show car has been designed solely at the Peugeot Style Studios in China. Sitting atop 22inch wheels and weighing in larger in every dimension than a Range Rover, the Peugeot SxC is an 'impressive size' according to Peugeot, but also harks back to design elements of previous concepts such as the BB1, EX1 and SR1.

Lotus Exige S Roadster Official: Price (£52,800) and Specs

It’s the first properly good news from Lotus for a while, and looks a promising offering at the same price (£52,800) as the tin top Exige S and, remarkably for a convertible, actually weighing less than the hard top – although by only 10kg. The Exige S Roadster gets the same 3.5 litre V6 as the coupe which means 345bhp, 295lb/ft of torque and a 0-60mph of a very respectable 3.8 seconds, but it does lose the coupe’s rear wing and front splitter for better airflow. The folding roof on the Roadster is a manual affair, but Lotus say fresh air motoring is just ‘Two clicks and a roll away’, so the manual roof is probably the best – and lightest – option.
