2020 Chevy Bolt gets 259-mile EPA range

The current Bolt is rated at 238 miles.

[Updated with official confirmation] General Motors appears to have upgraded the Chevrolet Bolt's battery for the 2020 model year.

The Environmental Protection Agency lists an official range estimate of 259 miles for the 2020 edition, representing a modest 21-mile gain over the current model year.

The change bumps the Bolt above several rival EVs including the Hyundai Kona Electric with 258 miles, the entry-level Tesla Model 3 Standard Range Plus with 240 miles, and Kia's Nero and Soul EVs with 239 miles and 243 miles, respectively.

The 2020 Bolt presumably integrates a revised battery with slightly more storage capacity, likely adding 5-10 kWh to the previous 60-kWh module.

GM has promised to launch several models on the Bolt's platform architecture. The next offering is expected to be a small crossover, consistent with the Chevy 'Menlo' that recently appeared in China. A higher-capacity battery will presumably help keep larger models comfortably above the 200-mile mark.

Update: GM has confirmed that its battery engineering team tweaked the Bolt's cell chemistry to increase energy density. The changes were made without requiring any modification to the battery module.
