Nothing wrong with getting more interior space but if this is true, with a more aerodynamic body the Bolt could have more range.[T]he Bolt broke new ground. “It’s a bit of a segment buster,” Norris said. “We call it a C-segment interior on a B-segment platform.”
“When we designed the Bolt EV, we kind of had this image of the vehicle as the next-generation of family vehicle, a reinventing of what a family car would be,” Norris said. “So it’s got this big spacious interior volume, a ton of trunk space.”
They did not ignore aerodynamics, but chose to maximize interior space. The hatchback/small wagon form factor will by definition be less aerodynamic.” Norris’ design team incorporated a spoiler and sharply creased winglike canards along the tail edge of the car. Other tricks were underbody paneling, air dams and active grille shutters that close at certain speeds to streamline airflow. Designers even adjusted the radius of the A-pillar, modified the mirrors and fine-tuned tire coverage.
“No fewer than six full-sized iterations of the Bolt underwent wind-tunnel testing.”
“Small-car design has always been a challenging area because you’re trying to deliver more for less. This is a pretty unique execution.”
