Bolt EV — first generation (2017–2023)

2017, 2023 Factory-verified

2017: LT, Premier: S; the 2017 guide rates it 200 hp (150 kW) and 266 lb-ft (360 N-m); the 2023 lists file it as an automatic electric transmission; the vehicle has no other transmission code (GM prints MMF as an electric drive unit transmission and the car has no MF1, so it stays here rather than in Axles)
