Despite rumors of Daimler and Renault collaborating on a four-door Smart model, no official tie-up between the two companies has been announced. That could change next year when Daimler will reportedly decide who its small-car partner will be. Daimler is getting even more heavily into the development of small cars, both with its Smart brand and the Mercedes-Benz A- and B Class offerings that might one day make it to America.

Renault is planning a line of ultra-cheap small cars and is putting together a range of electric vehicles that will certainly feature new, small platforms. Like Daimler, the French automaker is talking to other companies about joining forces to save money on developing small cars, so a Daimler-Renault alliance isn't a fait accompli. According to Automotive News, Daimler CEO Dieter Zetsche says the company will announce its chosen partner by the middle of 2010.
