The drivetrain in the new Mercedes-Benz S-Class “Hybrid” develops a maximum power of 241 kW/340 hp – a new record for cars with hybrid drive systems. The V8 CDI diesel engine develops 191 kW/260 hp and 560 Nm of torque. The two electric motors, which have a combined output of 50 kW/70 hp, make for optimized ride comfort and acceleration. Thanks to the second electric motor, the diesel can be started at any time without transition, independently of driving mode. The electric motors are powered by a 1.9 kWh nickel-metal hydride battery in the trunk of the S-Class vehicle. Energy is recovered during braking, and the V8 diesel engine recharges the battery while the vehicle is in motion.
The S-Class Hybrid accelerates from 0 to 100 km/h (62.1 mph) in 7.6 seconds.
