The Mercedes-Benz S 500 PLUG-IN HYBRID (earlier post) can cut CO2 emissions by some 43% when recharged using the European electricity mix and by up to 56% when using hydroelectricity compared to the conventional S 500 model on a full lifecycle basis, according to the environmental certificate awarded by TÜV SÜD.
TÜV SÜD awarded the life cycle assessment environmental certificate in accordance with ISO TR (technical report) 14062. (ISO/TR 14062:2002 describes concepts and current practices relating to the integration of environmental aspects into product design and development, and is applicable to the development of sector-specific documents. It is not applicable as a specification for certification and registration purposes.)
The award is based on a comprehensive assessment of the S 500 PLUG-IN HYBRID, taking into account ISO 14040 and 14044 regarding life cycle assessment (principles and general requirements, definition of goal & scope, inventory analysis, life cycle impact assessment, interpretation, critical review) and ISO 14020 (environmental labels and declarations – general principles) and ISO 14021 (criteria for self-declared environmental claims.) The certificate documents the model’s environmental performance from development through to recycling, across the entire lifecycle. (All three hybrid S-Class models—S 400 HYBRID, S 300 BlueTEC HYBRID, and S 500 PLUG-IN HYBRID—are covered in the TÜV SÜD document.)
Over the entire life cycle, comprising manufacture, use over 300,000 kilometers [186,411 miles] and recycling, clear advantages result compared with the S 500. External charging with the European electricity mix can cut CO2 emissions by some 43 percent (35 tonnes). Through the use of renewably generated hydroelectricity a 56 percent reduction (46 tonnes) is possible.—“Life cycle environmental certificate Mercedes-Benz S-Class including S 500 PLUG-IN HYBRID”
The Mercedes-Benz S 500 PLUG-IN HYBRID offers peak system output of 325 kW (436 hp) and 650 N·m (479 lb-ft) torque, accelerates from 0 to 100 km/h in a fast 5.2 seconds and can drive up to 33 km (20.5 miles) purely electrically. The certified consumption in Europe is 2.8 liters/100 km (84 mpg US)—lower than Mercedes initially suggested upon the vehicle’s unveiling in 2013—which corresponds to 65 g CO2/km emissions. Key elements of this performance are the V6 biturbo and the intelligent hybrid drive.
The 3.0-liter V6 biturbo comes from the M276 engine family and features the BlueDIRECT injection and combustion system. The hybrid transmission is based on the 7G-TRONIC PLUS 7-speed automatic transmission. The plug-in-hybrid system in the S-Class is based on the Mercedes-Benz parallel hybrid modular system. The common system-specific feature is the additional clutch integrated between combustion engine and electric motor. The 8.7 kWh high-voltage lithium-ion battery can be externally recharged via the charging socket in the right-hand side of the rear bumper.
Plug-in hybrids offer our customers the best of both worlds; in the city they can drive in all-electric mode, while on long journeys they benefit from the combustion engine’s range. In addition, hybridization not only makes the combustion engine lighter, it also brings with it a special type of dynamic performance—making driving an absolute pleasure.
The new S 500 PLUG-IN HYBRID is the spearhead of our hybrid strategy. It offers the power and performance of a V8, but runs on as little fuel as a compact model—and it is able to cover more than 30 km with zero emissions. The upshot is a unique combination of luxury, driving pleasure and environmental compatibility.—Professor Dr Herbert Kohler, Chief Environmental Officer at Daimler AG
The plug-in will be offered as the S550 PLUG-IN HYBRID in the US—the first hybrid model in the US for the new S-Class.
