Executives from Mercedes-Benz haven't been coy about the company's EV plans -- it wants to go head-to-head with Tesla. As part of this strategy, Bloomberg reports that Mercedes is getting ready to introduce four electric vehicles, including two sedan models and two SUVs. The new fleet is said to be the starting point of a new sub-brand for Mercedes, although the German automaker still hasn't decided what that will be called. Last month, Mercedes' David McCarthy revealed that a concept electric would be shown sometime in September. In other words, it won't be long before we see what Mercedes has up its sleeve.
