The C70 only comes in one model, a hardtop convertible. It is powered by a 227-hp turbocharged 2.5-liter inline-five-cylinder engine matched with a five-speed Geartronic automatic transmission. Safety features include electronic stability and traction control and anti-lock brakes with brake force distribution. In addition to the front airbags, there are front side airbags, and air curtains which activate upwards from the doors, even with the windows rolled down. The Rollover Protection System, a pop-up rollbar, is activated by a "pyrotechnic charge", which will smash the rollbars through the glass if the roof is up.For 2012 two trims are added to the base; the Premier Plus and the Platinum. These trims get enhanced features like HomeLink, Keyless Drive and Park Assist.
