The GM-athon continues unabated today and even though this isn't Maximum El Camino Day related, it is pretty damned interesting. The prototype supplier of the Li-ion batteries for the much anticipated Chevy Volt, Continental Automotive Systems, has just stated production by the end of this year for similar batteries in the Mercedes S400 BlueHYBRID. Interesting we say because we know that BMW, GM, and Chrysler were bosom buddies for hybrids until Cerberus broke up the party, and now yet another Deutschland partner may have emerged. Seriously, how many companies does it take to make a gasoline and electric powered car?[AutoElectronics via GMInsideNews]
