Rumors were recently confirmed  that, yes, Mercedes is planning on building an electric car or two and now some of the details are starting to be firmed up. In an interview with German business daily, WirtschaftsWoche, Thomas Weber, a Mercedes board member responsible for research and vehicle development, let it be known that the company is building what was originally meant to be the fuel cell-powered A-Class (and possibly B-Class) as an all-electric model. Because of its “sandwich” construction and pre-existing electric drivetrain, these cars should be the first to join the electric Smart in the e-Mercedes lineup.

Another magazine, Automobilwoche, as well as reporting 2010 as the year of the e-Mercedes arrival, states that the supplier of the battery for the cars would be none other than the American firm Tesla Motors. The source of their information was not revealed and since this has not been officially stated by either company, it’s still somewhat speculative. We know from talking with Tesla’s Elon Musk that something is going on between them and Mercedes and it’s definitely not a motor for the Whitestar, since Musk made it clear that Tesla products will remain gasoline-free. We also know that Daimler claims to have solved the thermal issues associated with lithium ion batteries of a certain chemistry by integrating battery cooling systems with that of the car. Then again, Continental has already been named a battery supplier for the Mercedes S 400 hybrid.

Mercedes is not slacking when it comes to building concepts and releasing cleaner vehicles. But, in a fairly standard automotive move these days, while the engineers are working, the executives are complaining about patchworks. Speaking in Switzerland, Daimler CEO Dieter Zetsche said that the variety of environmental regulations around the world are a big challenge to his company and all automakers. Automotive News (subs req’d) cites the EU’s goal of having new vehicles meet a 120 g/km limit of CO₂ while the U.S. is focusing its laws on fuel economy. Zetsche described the situation this way: “Our engineers sometimes feel as if they are forced to play European soccer on an American baseball diamond by Japanese sumo wrestling rules.” Zetsche singled out moving targets and different attribute qualifications as problems areas. “We’re not fighting against environmental regulations. Our ultimate goal is emission-free driving. It’s just that this ‘patchwork quilt’ of regulations doesn’t necessarily support us in getting there,” he said. Of course, Zetsche’s argument would be a lot more convincing if global automakers didn’t already sell different vehicles in different markets. They’ve been working within a patchwork for decades, sometimes one of their own design.
