Aston Martin V12 Vantage and DBS Carbon Black Editions: first official pictures

Aston Martin has unveiled rather aggressive-looking special versions of its V12 Vantage and DBS supercars, under the Carbon Black Edition banner. No prizes for guessing they're black and laced with carbonfibre trinkets.

Historic Roper steam-powered motorcycle at Las Vegas auction - Autoweek

In September we told you about one of the world's oldest four-wheeled machines going up for auction at an RM event. In January 2012, the perfect companion piece to that $4.6 million horseless carriage is being sold--a 1894 Roper Steam-Powered Runabout motorbike. The Roper bike is the second of two built by Sylvester Roper of Roxbury, Mass., and is regarded as one of the world's oldest, predating the earliest Orient, Indian and Harley-Davidsons.

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.
