The Chevrolet Bolt hasn’t changed much since it was introduced in 2016, but there appears to be a significant update on the horizon.

As noticed by Car & Driver, the EPA says the 2020 Bolt will have an increased range of 259 miles (417 km). That’s 21 miles (34 miles) more than its predecessor and is significantly longer than rivals such as the Nissan Leaf Plus (226 miles / 364 km), Kia Niro EV (239 miles / 385 km) and Tesla Model 3 Standard Range Plus (240 miles / 386 km). The model even tops the Hyundai Kona Electric which has a range of 258 miles (415 km).

Despite the increased range, the model appears slightly less efficient than before as the 2020 Bolt has an MPGe rating of 127 city, 108 highway and 118 combined. That’s a slight dip from the 2019 model which was rated at 128 city, 110 highway and 119 combined. As a result, it costs an extra cent to drive 25 miles (40 km).

Little is known about the updated Bolt, but the publication believes the car has been equipped with a revised battery pack that features an improved chemistry. That sounds like a logical explanation, but nothing is official as of yet.

While the range sees a significant improvement for 2020, there doesn’t appear to be any other drastic changes. However, Car & Driver says we can expect a “few new features” and a revised color palette that swaps out Shock Yellow for Cayenne Orange Metallic and Oasis Blue. The publication also says the familiar 200 hp (149 kW / 203 PS) electric motor carries over.
