Replacement Parts for the Mercedes Benz E500 at PartstrainWritten by Jenny McLane
The award-winning Mercedes-Benz E-Class line will soon feature new 2006-model E350 sedan and wagon, both powered by a new-generation 3.5-litre V6 engine that produces 268 horsepower – a 20 percent increase over 3.2-litre engine.
The E500 stands at top of regular E-Class sedan lineup, which also includes V6-powered E320 and new-for-`05 E320CDI turbo diesel. The 3.5-litre V6 features four valves per cylinder; double-overhead camshafts and variable valve timing for both intake and exhaust valves. This is first time Mercedes-Benz has used double-overhead camshaft technology on its V6 engines.
One of most powerful engines for its size, 3.5-litre all-aluminum V6 produces 268 horsepower and 258 lb-ft of torque, with maximum torque available from 2,400 rpm all way up to 5,000 rpm. At only 1,500 rpm, new V6 already develops 87 percent of its maximum torque. E class models have hood, front fenders, trunk lid, and suspension sub frames are aluminum, as are numerous suspension pieces. There is increased structural use of high-strength steel as well. The design and construction helps ride comfort and handling of all E-Class models, but E500 and E55AMG have a special trick as standard equipment - Airmatic DC (Dual Control) semi-active air suspension, derived from that used in premium S-Class. The air springs and shock absorbers use electronic sensors and computer-controlled actuation to match suspension response to road conditions, driving style, and cornering force.The E350 and E500 rear-drive models come equipped with world’s first seven-speed automatic transmission. The seven-speed transmission improves acceleration from 0 to 100 km/h by up to 0.3 seconds and allows significantly quicker acceleration in highway passing situations. At same time, shifting is even smoother than with previous five-speed.
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.
