If there was any doubt about the theme of Frankfurt 2007, it was vividly dispelled by Mercedes-Benz’s extravagant, Cirque du Soleil-esque floor show of twirling trees, dancing flowers and giant birds, emphasizing the firm’s commitment to eco-friendly, sustainable mobility.
Oh, and there were some new cars on hand, too — 19 of them, in fact — which Daimler chief Dieter Zetsche called “True Blue Solutions” to the seemingly contradictory goal of melding driving pleasure with social responsibility.
The star of the show was the striking F 700 research vehicle, joined by seven hybrids from five different model series; an E300 Bluetec version of the E320 that was voted “World Green Car of the Year 2007”; three Smart cars with electric, gas-electric and diesel-electric powertrains; an E350 CGI with second-generation gasoline direct injection; B-Class cars with natural-gas and fuel-cell drives; S300 and E300 Bluetec Hybrids; an S400 Hybrid; and the ML450 hybrid, which, when it comes to market in 2009, will be the world’s most economical gas-electric-powered SUV in its class.
The ML’s two-mode hybrid system allows it to be driven with just its two compact electric engines or in tandem with its V6 gas engine, the combined system boasting an output of 321 horsepower and 354 lb-ft of torque. A new four-speed transmission is said to combine the advantages of a multiple-speed automatic with the efficiencies of a stepless CVT gearbox. The ML will also be fitted with such additional energy-saving technologies as braking-power regeneration and the stop-start function found in the Smart hybrid. Expect stop-start to appear in many more models in the near future.
Also slated for 2009 European release is the S400 Hybrid, whose 279-horsepower gas-electric powertrain will make it, says Mercedes, the most fuel-efficient as well as the cleanest-running gas-powered luxury sedan. The S400 Hybrid’s compact electric module, which also functions as the starter motor and generator, is comprised of a disk-shaped electric engine that gets its power from a lithium-ion battery pack in the engine compartment. Under full throttle, the electric motor’s “boost effect” adds 118 lb-ft of torque to the gas engine for exemplary acceleration.
In 2010, Mercedes will release the E300 Bluetec Hybrid, combining a new four-cylinder diesel engine with a compact electric module for a maximum of 204 horsepower and an amazing 413 lb-ft of torque from only 2.2 liters of displacement.
Beyond 2010 will come a C300 Bluetec Hybrid, an S400 Bluetec Hybrid and, perhaps, the production version of the F 700 with its innovative DiesOtto powertrain, which combines the cleanliness of a gas engine with the power and efficiency of a diesel.
At the end of the presentation, the floor of the grandiose stand was cheek to jowl with new cars bursting with innovative technology, an impressive demonstration that Mercedes is leaving no stone unturned in its quest for sustainable mobility. -- Greg Brown, Contributor
