Elon Musk says Tesla's new Semi trucks are BAMFs. Yes, for those of you at home, that's the widely known acronym for "Bad Ass Mother F***er." Musk playfully threw out the acronym as a "scientific term" Tesla's development team used as they designed the new big rigs. The name sounds ridiculous — but the specs, if they wind up being legit, are actually pretty impressive.

Once you add a load of freight, like the maximum U.S. highway-legal load of 80,000 pounds, truckers will be able to hit 0 to 60 mph in 20 seconds. Musk showed off an animation of the Tesla Semi in a race against a traditional diesel truck, and the wait for the diesel truck to finish became comical. Musk said the Tesla Semi can also achieve speeds of 65 mph up a 5 percent grade, compared to diesel trucks which can only achieve speeds of 45 mph. That goes along with a 500 mile range per charge, at maximum weight at highway speed. Musk says the company was able to achieve these performance number by designing the Semi after a bullet compared to diesel trucks that are more like "a barndoor." There you have it: Elon Musk says the Tesla Semi trucks are BAMFs designed to drive like bullets. You should probably give them room on the highway. Featured Video For You
