Sydney – The top-of-the-range luxury saloon from Mercedes-Benz is now available with a further-optimised version of the popular 3.0-litre turbo-diesel V6, the same power unit that has impressed with it prodigious torque, remarkable fuel economy and exceptional emission levels in other Mercedes-Benz passenger car models. The S 320 CDI is now available in Mercedes-Benz showrooms and is priced from $190,900 (excluding dealer delivery and statutory charges). This is the first time Mercedes-Benz has offered turbo-diesel power in the S-Class to Australian customers.
The newly developed CDI (Common-rail Direct Injection) six-cylinder engine will join the range of engines for the award-winning S-Class. It has an output of 173 kW, topping the figure for the engine in the preceding S 320 CDI (not sold in Australia) by 15 percent. Maximum torque has increased by eight percent, from 500 to 540 Newton metres which is available between a low 1600 and 2800 rpm. These remarkable values make the direct-injection diesel unit one of the most powerful in its displacement class. Combining this exceptional engine with the 7G-TRONIC seven-speed automatic transmission as standard equipment ensures the best possible use of its outstanding output and torque potential in any driving situation.
Lightweight construction as a factor in exemplary diesel driving pleasure.
The choice of materials, technical design, fuel injection and engine management system of the V6 diesel engine reflect the state of the art.
Mercedes-Benz has developed an aluminium crankcase with cast-in grey iron cylinder liners for this unit, which makes a major contribution to weight reduction. As a result, the new six-cylinder engine weighs a total of only around 208 kilograms (acc. to DIN) and achieves a remarkable power-to-weight ratio of 0.83 kW/kg; a major contribution to the outstanding agility and handling offered by the S 320 CDI by the new engine.
