Mercedes chose to launch the all new CLS 53 AMG model separately to the rest of the range, because they new it's advanced technology deserved its own fanfare, and it's quite some kit. It uses a 48 volt electrical system to power an separate electric turbo that provides instant low down response while the bigger traditional exhaust gas turbo spins up so you get a huge amount of shove immediately, meaning an end to turbo lag. It's also got a clever combined starter/alternator called EQ-boost that functions also as a hybrid electric motor and whilst it cant run on electric power alone, it does provide immediate extra thrust off the line making the throttle response electric both literally and figuratively. As all new CLS isn't getting the 4.0 V8 63 AMG engine, then this new E53 model is set to be the range topper.
