Cummins is better known for its diesel truck engines, but the Fortune 500 company makes its money from also selling generators and alternative energy power sources.

So maybe, it shouldn’t come as a surprise then to learn today that Cummins has acquired Brammo, Inc. and its electric drivetrain business.

Before we should go further, we should point out that Polaris still owns Brammo’s motorcycle business, which it bought separately back in 2015, and that this purchase by Cummins applies only to the parts of Brammo that Polaris didn’t buy, including Brammo’s race bike, the Empulse RR.
