According to General Motors' general director-electrification, Tim Grewe, prototypes of the Chevrolet Bolt are exceeding 200 miles of electric range in internal testing.
Crewe spoke to media recently at GM’s Alternative Energy Center and confidently stated that the production Bolt will exceed the 200 miles of range that Chevrolet had originally announced.
EPA testing for the Bolt has not been completed, but GM is confident in the results from internal tests.
Additionally, Greg Smith, General Motors' engineering group manager-global EV battery packs, says that compared to the Chevy Spark EV, the Bolt's battery has twice the mass and triple the energy. Smith adds that the Bolt's battery actually increases the car's chassis torsional stiffness by 28% due to it being an integrated part of the Bolt's floorpan.
“A high-mass, large battery turned into a benefit that is a big factor in making the car fun to drive."
