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.
