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.

Ferrari shows next Enzo's HY-KERS V12 at Beijing

Ferrari stole a surprise march at the 2012 Beijing auto show when it announced a few details about its forthcoming Enzo successor. The powertrain you see here is essentially the hybrid supercar architecture which'll underpin the new hypercar being readied for launch later in 2012. Ferrari chief Amadeo Felisa told CAR the electric powertrain would lop 10% off the 0-124mph time - and its V12 is related to that in the F12, but with more power and 40% lower CO2 emissions.

2015 Ram ProMaster City to join commercial lineup

Ram has announced that it will add the Ram ProMaster City van to its commercial lineup for 2015, growing the range from six vehicles to seven. We've known that this vehicle has been in the works for years, but this is the first time a sales time frame has been released. Much smaller than the 2014 Ram ProMaster -- smaller even than that Caravan-based C/V Tradesman -- the ProMaster City will be based on the petite Fiat Doblo.
