Mercedes-Benz has announced details of their first application of the Two-Mode Hybrid system that they have developed alongside General Motors, Chrysler and BMW. The ML450 hybrid is coming for 2009 powered by 3.5L V-6 engine mated to the Two-Mode transmissions that will be supplied by GM from their Baltimore transmission plant. Along with BMW’s X6 crossover it means that all of the first batch of Two-Mode vehicles will be built in the US plants (the ML is built at the Mercedes plant in Alabama).

The ML450s gas engine churns out 279 hp 249 lb-ft of torque on its own and the combined output of the electric motors bumps that to 321 hp and 354 lb-ft. The hybrid ML consumes gasoline at the rate of 30.5 mpg with CO2 output of 185 g/km. A 288V nickel metal hydride battery pack recaptures energy from the regenerative braking and dispenses it when needed during acceleration or at lower speeds when the vehicle can run on electricity alone.

2009: ML 450 HYBRID - the most economical hybrid SUV in its lesson

Mercedes-Benz is plus presenting a further CO₂ world champion in its lesson at the IAA: the ML 450 HYBRID, which will come onto the market in 2009 as the world’s most economical SUV petrol hybrid in its lesson. Its innovative two-mode hybrid system means it can be driven with just the electric engine; and the vehicle meets the highest expectations in terms of consolation. The V6 petrol engine produces 205 kW/279 hp and 338 Newton metres of torque, while the two-mode hybrid module with two electric motors, develops 45 kW/61 hp. The end conclusion is a

In the ML 450 HYBRID two compact electric engines are used, developing a total potential output of 120 kW/163 hp. They take up a lot less space in the vehicle than comparable systems, thus guaranteeing that that is an ideal package. The system, strange in its kind, with four fixed gears, combines the advantages of a multiple-speed robotic transmission with those of a stepless CVT transmission. The two electric motors are integrated in the innovative two-mode hybrid transmission of the ML 450 HYBRID. that drive is optimised both for the city and for country roads. Voltage is supplied by a 288-V battery, which makes it possible to store considerable quantities of electrical energy. In interaction with an intelligent energy management system, that vehicle features all the full hybrid characteristics such as driving entirely under electric capability, the start-stop function of the internal-combustion engine, boost effect and braking energy recovery.

Mercedes-Benz is thus offering a hybrid technology which guarantees low fuel consumption, effortless performance, the highest level of consolation and a fully utilisable boot volume without load space restrictions. The two-mode hybrid additionally improves performance and fuel consumption, particularly at higher speeds, giving it a further advantage by other hybrid concepts available on the market.
