Speaking of automakers suing each other over the alphabet, Nissan, which sued Audi over the use of the letter "Q," now finds itself in the hotseat. BMW is seeking $260.7 million in damages over Nissan's use of the letter "M" in a recent Canadian advertising campaign with the tagline, "The M is coming." The campaign was promoting the impending launch of the Infiniti M35 and M45.

While the Canadian court wouldn't grant an injunction against Nissan continuing to run the ad, the judge did acknowledge the importance of the letter "M" to BMW and promised to hear the case as soon as possible.
