Sounds like the Bolt has even less in common with the Gamma platform than I thought:
GM’s new electric-vehicle architecture is known simply as BEV II; it doesn’t have a Greek-letter name like the rest of the company’s platforms. Asked if it shares anything with the Gamma platform that underpins the Chevy Sonic, Tavel shrugs. “The liquid sound deadener,” he offers. The Bolt uses a MacPherson strut suspension in front and a torsion-beam arrangement at the rear. A handwritten sticker on the doorjamb suggests that this particular development car tips the scales at 3512 pounds—heavy for a car this small until you consider that hundreds of pounds of batteries cling to the underside of the floor.
