2012 Mercedes SL Spied

2012 Mercedes SL caught testing When the fifth generation Mercedes SL hit the headlines back in 2002 it was a revelation, offering as it did the best of a coupe and a convertible and a completely bonkers performance version in the SL55.

And Volvo’s new Flywheel KERS system does look promising. Volvo are currently running UK tests of a KERS flywheel system developed by Flybrid Automotive, which takes kinetic energy generated under braking and stores it in a flywheel fitted to the back axle.
