Mercedes testing C-Class plug-in hybrid modes in Germany

Testing appears to be underway for what would be the first Mercedes-Benz C-Class with a hybrid powertrain. We can see a pair of the prototypes undergoing testing in Germany, with one, a C-Class Wagon, still heavily clad in camouflage and featuring a more noticeable outlet on the passenger side of its rear bumper.
There's also a more production-looking sedan, which features a not-so-discreet flap over its rear-bumper outlet. It's difficult to speculate on power outputs for this fuel-sipping C-Class, although our spies seem to think that this car will feature some combination of a four-cylinder gas engine with an electric motor, although just which four is unclear (note, we wouldn't mind if MB fit its 2.0-liter turbo with some batteries and motors). Regardless, the four-pot/electric motor seems like a pretty reasonable combo, although it probably means that Mercedes won't be challenging the six-cylinder-powered system of the BMW ActiveHybrid3 any time soon.
When the plug-in C-Class arrives later this year as a 2015 model, it will likely offer a full range of driving modes, including both gas or electric, only, as well as a more traditional hybrid mode.

Daimler exec hypothetically discusses 3-cylinder engines for small hybrids

Is three the magic number of cylinders for Mercedes-Benz parent Daimler and its efforts to build smaller powertrains for its compact hybrids? Potentially, yes, the German automaker could see the need for three-cylinder mills, Automotive News reports. The company doesn't have any plans for them as of yet, though. Daimler executive Bernhard Heil talked with Automotive News about the challenges of using four-cylinder engines in a front-wheel-drive setup and said that three-cylinder engines could work in transverse-mounted powertrains for hybrid cars. For now, though, the company doesn't actually have any plans to go in that direction, Mercedes-Benz spokesman Christoph Horn said in an e-mail to AutoblogGreen. Horn wrote that Heil "actually said that if ever MB would use a three-cylinder engine than [it would be] in a configuration where space is restricted, such as when using a hybrid power train in a compact car." Of course, the only compact "hybrid" that Mercedes-Benz has is the 2015 C-Class, but that refers to the "hybrid" body is made of 48-percent aluminum, up from the current nine percent, as well as steel. It has nothing to do with the powertrain. Beyond that, there's always the Mercedes-Benz S500 Plug-in Hybrid that the company unveiled at the Frankfurt Motor Show last fall, but that model, which will debut in Europe later this year and arrive stateside next year, has a 3.0-liter turbocharged V6 and an 80-kilowatt electric motor that propels the plug-in from 0 to 62 miles per hour in 5.5 seconds. Not exactly three-cylinder territory, that.

Daimler boss says fuel cell vehicles will be disappointing for at least 10 years

Daimler AG CEO Dieter Zetsche is pretty confident about the imminence of self-driving cars. Hydrogen fuel-cell vehicles? Not so much. He didn't even get into the possibility of self-driving fuel-cell vehicles, but we're okay taking future technologies one at a time. Zetsche, in an interview from the Detroit Auto Show last week, said the automotive industry is about a decade away from avoiding disappointing experiences with production fuel-cell vehicles, In Auto News says. Zetsche was quick to note that the Mercedes-Benz parent entered into a fuel-cell partnership with Ford and Nissan early last year in an effort to split costs and speed things along, with the expectation that the group would develop something together by 2017, but even that won't be able to smooth things out fully. Toyota and Hyundai have said they'd have their own production vehicles on the road sooner than that. Multi-corporation-partnerships notwithstanding, Zetsche bemoaned the high costs, lack of vehicle volume and minimal refueling infrastructure as the proverbial roadblocks to more rapid development and adoption of fuel-cell vehicles. As it is, the US has just 10 publicly accessible hydrogen refueling stations, eight of which are in Southern California, according to the US Department of Energy. As for autonomous automobiles, Zetsche was more upbeat. Daimler already has what it calls the "Distronic" cruise control system that includes an automatic braking feature and has successfully driven a car 60 miles with "with relatively modest adjustments to the existing onboard technology."
