Impressive power and fuel economy, race-track performance and functionality – certainly not contradictory terms for the CLS 63 AMG. Its AMG 5.5-Liter V8 Biturbo Engine combines an output of 410 kW (557 hp) and 720 Nm of torque with a combined fuel consumption of just 10.4-9.9 l/100 km and CO2 emissions of 243-231 g/km. The performance-oriented 4MATIC all-wheel drive developed by Mercedes‑AMG (optional extra) has a rear-biased torque distribution of 33:67 as well as light pre-lock torque, to combine optimum traction and hallmark AMG driving dynamics. The superior handling characteristics also come courtesy of the AMG SPEEDSHIFT MCT 7-speed sports transmission as well as the AMG RIDE CONTROL sports suspension. This can be manually adjusted to any of three settings, "Comfort", "Sport" and "Sport Plus", and includes a second, more direct, steering characteristic map in the two "Sport" settings – for use on the motorway or race track.
