A C8-based electric sports vehicle, in my opinion, would use the Rimac method. When the hybrid Grand Sport successor is publicly described, we should expect to see battery cells in the C8’s very high structural tunnel. In the Cadillac Celestiq, GM already stacks cells in a tunnel structure. However, without an engine or gearbox, there would be plenty of room at the back to stack batteries. Working out the positioning of the front motor for the base-level hybrid Corvette would also transition easily into an all-electric variant. Another engine would simply need to be put at the back, and GM has a large parts bin to select from.
Will lithium-ion batteries have enough energy density to make it all work? Corvette customers are unlikely to be interested in a short-range electric ‘Vette. The C8 is large for its class, but it’s hardly a Hummer EV with a 200-kWh, 3,000-pound acid mattress. GM has many patents on solid-state batteries, but commercialization is likely some years away.
