Elon Musk rips Mercedes' electric vehicle goals, Mercedes hits back

After Elon Musk expressed disappointment with the electric vehicle investments of Daimler, the parent company of automaker Mercedes-Benz, the company shot back at Musk with its grander electric ambitions. 

On Sunday, a USA TODAY Money tweet reported Daimler's commitment of $1 billion dollars to upgrade an existing Mercedes factory and build a new battery plant in Tuscaloosa, Alabama, where Mercedes plans to produce its futuristic, all-electric SUVs. Musk, however, was not impressed with just a $1 billion dollar investment from such a massive, legacy automaker.
