The so-called X76 electric drive unit powers the 2027 Bolt. It was designed in-house at GM. Chevrolet claims the X76 drive unit was “designed from the ground up to maximize driving range and deliver improved efficiency in cost and energy usage. The permanent-magnet motor uses minimal rare-earth materials for improved costs. Segmented magnets reduce heat build-up and energy loss, and silicon carbide inverter materials minimize energy loss between the battery and drive unit.”

The 2027 Bolt is the 10th GM EV model to use the X76 drive unit. Sharing this component across the GM EV lineup results in cost savings for the customer [In theory, not always in practice- AutoCrat]. The Bolt has a so-called “blended regenerative braking system.” Whether or not the driver employs One-Pedal Driving [11] mode, software in the Bolt prioritizes technology that returns braking energy back to the battery for improved range. “The braking system has been optimized for consistent pedal feel during both regen and friction braking, a key improvement over the previous Bolt,” Chevrolet said.
