Mercedes-Benz has laid out a long Road to the Future, detailing its efforts to create "fuel-efficient and environmentally-sustainable premium automobiles without the need to forgo the characteristic brand features." That's fancy talk for having your German chocolate cake and eating it, too.
The three areas on which the tri-pointed star wants to focus are fitting vehicles with the latest internal combustion engine technology, including smaller engines, gasoline direct injection, turbocharging, and BlueTEC; improving vehicle aerodynamics, weight, and energy management (BlueEFFICIENCY); adding more "hybrid" technologies like start/stop functions and a fully-electric-capable 2-mode hybrid drive; and creating zero-emissions vehicles.
Mercedes wants diesels as clean as gas engines, gas engines as efficient as diesels, diesel hybrids, lighter cars, better gas mileage, leprechauns, unicorns, and rainbows for everyone. Well, not those last three, but you get the picture. To understand the full sweep of Mercedes' efforts, follow the jump for the full press release.
The word came down yesterday from Auto Motor und Sport that the Volkswagen TDI hybrid Golf concept that debuted in Geneva wouldn't make the transition to production. According to the print edition of the German rag (translation courtesy of TTAC), the "forward-looking diesel-hybrid is already a thing of the past." That came as a surprise considering how well the concept was received and rumblings we heard from VW's people on the floor that the 69-mpg (European cycle) Golf was destined for the road. We shot off an email to a Volkswagen exec here in the States who responded by saying that, "It was just a concept. No plans to produce were announced." Too bad. Guess we'll have to make due with the gasoline-hybrid Golf that's due out in the next few years.
The Geneva Motor Show this week was riddled with diesel hybrid concepts from several manufacturers including Mercedes-Benz, BMW and Volkswagen. All of those systems seem destined for production in the next couple of years, particularly the VW Golf TDI hybrid. One company that won't be joining that party is Toyota. Speaking to Automotive News at the Geneva Motor Show this week, Toyota President Katsuaki Watanabe said the hybrid pioneer had no plans to introduce any diesel hybrids.
At the Detroit Auto Show, Watanabe announced that Toyota would offer a diesel engine in the Sequoia and Tundra in 2010. Toyota already offers a variety of diesels in the European market. However, according to Watanabe, the combination of diesel and hybrid doesn't yield enough of an incremental improvement in efficiency to justify the combined cost premium of both. At this point, the Toyota Hybrid Synergy Drive system is not suitable for use in the big trucks, which is why Toyota is following just the diesel path for now. Toyota USA VP Bob Carter told AutoblogGreen in Chicago that diesel hybrids are technically feasible and they are being developed (along with many other things as part of Toyota's $1million/hour in R&D spending), but Carter also said that the combination is not possible at a marketable cost.
One big difference between what was shown in Geneva and what Toyota currently has available is that the German hybrids were largely less expensive mild hybrids. These systems primarily provide start-stop capability and some electrical power boost. They also reduce parasitic losses by using regenerative braking energy to drive electrical accessories. One other thing should be kept in mind. Toyota Communications VP Irv Miller recently told us, "Flexibility is one of the beauties of Toyota."
When Mercedes-Benz premiered the new GLK compact SUV at the Detroit Auto Show in January, the styling struck most people as at best awkward. With the outward appearance of the full-size GL shrunk down to an Escape-sized vehicle, it still looks like a reject for a Chrysler Sebring crossover. Regardless of what you think of the exterior body work, the latest edition of the GLK that Mercedes is showing in concept form at Geneva next week seems to be capable of pretty serious mileage for an SUV/CUV. The Vision GLK BlueTec Hybrid is another in the series of models using the new mild hybrid system Mercedes is developing with BMW. In this case, Mercedes has combined it with the 2.2L four cylinder diesel for a total output of 224 hp and 413 lb-ft of torque. That's enough to move the GLK to 62 mph in 7.3 sec while getting 40 mpg (US). On the outside, the shell is covered in the same AluBeam paint that was on the anniversary edition AMG CL65 shown in New York last year, which looks absolutely stunning. The production version of the GLK debuts this summer and the mild hybrid system should start appearing in production BMWs and Benzes in 2009.
