Commercial vehicles with hybrid drive
In commercial vehicles, too, Daimler is pressing ahead with drastically reducing fuel consumption, CO2 levels, and exhaust emissions. These activities are grouped together in the “Shaping Future Transportation” initiative launched in late 2007. A key role in the quest for the drive system of tomorrow is played by hybrid technologies, which depending on the type of application are expected to bring about savings in diesel consumption of up to one-third.
With the Mercedes-Benz Atego BlueTec Hybrid, we are offering this particularly low-emission technology ex-factory for the first time in Europe. Its compact, lightweight four-cylinder diesel engine with a displacement of 4.8 liters develops an output of 160 kW (218 hp) and a maximum torque of 810 Nm. It also features a water-cooled electric motor, which has a peak output of 44 kW and a maximum torque of 420 Nm and is supplied by lithium-ion batteries with high energy and power ratings.
The electric motor is located behind the combustion engine and clutch, but in front of the transmission. In so-called parallel hybrid mode, the electric motor and combustion engine can power the truck either alone or in tandem. This architecture allows electric starting, regenerative braking, and boosting by
the electric motor and optimizes the characteristics of the diesel engine. This not only significantly reduces fuel consumption and exhaust emissions by up to 15 percent, but also makes for less noise emission. Use of the start/stop function during stops at traffic lights reduces fuel consumption, emissions, and noise to zero.
The first fifty Atego BlueTec Hybrid trucks were delivered to German customers from the goods distribution sector in early 2011. The Mercedes-Benz Atego BlueTec Hybrid received the “German Sustainability Award” in the category of “Germany’s most sustainable products/services” in 2010 and was voted
“Truck of the Year 2011.”
World leader in hybrid drive systems for commercial vehicles
Large numbers of buses and trucks of Daimler’s Freightliner and Mitsubishi Fuso brands are already in operation with customers in the United States and Japan. With more than 1,500 Freightliner vehicles, and over 1,100 light trucks and buses from Mitsubishi Fuso, Daimler is world market leader in hybrid drive systems for commercial vehicles. Together with the natural gas-powered Mercedes-Benz trucks, buses, and vans in Europe, the fleet of vehicles delivered by Daimler to its customers already numbers more than 15,500 commercial vehicles with alternative drive concepts in practical operation.
Buses are now being put to everyday use with customers in further product segments and regions. In North America, most of the 1,500 Freightliner M2 hybrid trucks have already been delivered to customers. Thomas Built Buses is now producing hybrid versions of the company’s legendary school buses. In Japan, the Fuso Aero Star Eco Hybrid is now already the second generation of hybrid buses to be launched on the market. In London, Europe’s largest fleet test with hybrid trucks was alreadyinitiated with ten Mitsubishi Fuso Canter Eco Hybrid vehicles in August 2008.
The Global Hybrid Center in Kawasaki, Japan, also opened in August 2008, now coordinates the worldwide hybrid activities of Daimler Trucks and is currently developing new systems. The first of a total of 30 Mercedes-Benz diesel hybrid buses have already been in regular everyday service since 2010.
This new vehicle concept is already shaping the technological shift towards the zero-emission vehicle.
