Replacement Parts for the Mercedes Benz S Class Hybrid SedanWritten by Jenny McLane
The combination of electric drive with 7G-Tronic automatic transmission ensures that S-Class "Hybrid" constantly operates at optimum level. "This reduces fuel consumption by 15 to 25 percent depending on driving cycle, while at same time enhancing comfort," says Prof. Herbert Kohler, Head of Vehicle Body and Drive Systems Directorate at DaimlerChrysler AG.Combining a V8 diesel engine with latest generation of hybrid drive systems developed jointly by DaimlerChrysler and General Motors, Mercedes Benz introduces S Class Hybrid, which unlike many conventional hybrids, system dispenses with a torque converter; this is replaced by hybrid-specific components. The hybrid concept is based on 7G-Tronic automatic transmission in combination with P1/2 hybrid transmission, which thanks to its compact dimensions does not restrict interior space. "The use of 7G-Tronic automatic transmission makes for a comfort level that is unique in world of hybrids," emphasized Weber. "Shifting is even faster and more convenient in continuously variable mode." Setting a new record for cars with hybrid drive system, S Class has a maximum output of 340 horsepower. The two electric motors have a combined output of 70 horsepower. The diesel can be started at any time without transition, independently of driving mode. The V8 diesel engine recharges battery while vehicle is in motion while energy is recovered during braking.
