Tier 1 Engineering unveiled the first battery-powered manned helicopter. The engineering firm retrofitted a used Robinson R44 helicopter with two electric motors powered by a large battery pack made by Brammo, the electric motorcycle maker turned battery pack manufacturer, fitted on the underbody of the aircraft.

The vehicle, which completed its inaugural flight just last month, serves as a proof-of-concept and test mule while Tier 1 Engineering develops a more advanced electric helicopter with its partners under the ‘EPSAROD’ development program. expand full story

Earlier this year, Polaris bought the electric motorcycle maker Brammo. A few weeks ago, we wrote about Vicotry, which is a Polaris brand, unveiling the Empulse TT. As we explained, the TT is pretty much just a rebranding of Brammo’s own Empulse R, but rebranding aside, last week, Polaris unveiled the first all-new electric vehicle resulting from the acquisition of Brammo : the RANGER EV Li-Ion Polaris Pursuit Camo. expand full story

Earlier this year, Victory Motorcycles bought Brammo’s electric motorcycle business and now Brammo’s Empulse R becomes Victory’s Empulse TT. Other than the badges and a light styling refresh, the bike is roughly unchanged. Going for $20,000 and with an advertised range of 140 miles, the Empulse could represent an interesting higher-end alternative to the very popular Zero electric motorcycles. expand full story
