It’s been a wild boxing match between the two satellite radio providers in the last year and while XM won the first round by being first to transmit, it seems that was XM’s only big hit. Sirius gave a mighty blow of its own last year when it announced that it would be getting Howard Stern and allowing the potty mouth DJ to say whatever he wanted. Sirius continued with what worked and got a great uppercut in the last week by stealing NASCAR from XM, its pride and joy.

And now continuing to drive home more hard-hitting punches, Sirius announced that it will be installed in Mitsubishi cars and trucks. This adds to the long list of automobiles equipped with Sirius such as Audi, BMW, DaimlerChrysler, Ford, Nissan, and Toyota. With the first six months being free and no activation fee, XM has to be wondering if Honda and GM will be enough to keep it in the lead.

Isn’t it great to see an underdog potentially win the fight?
