General Motors says the ’17 Chevrolet Bolt will travel 238 miles (383 km) on a single charge, making it the longest-range battery-electric vehicle on the market in its class and far-eclipsing original estimations.

“Chevrolet showed the world the production version Bolt EV earlier this year and in a few short months we’ve moved from that vision to a reality,” GM North America President Alan Batey says in a statement. “The Bolt EV is a game-changer for the electric-car segment and it will start to become available at Chevrolet dealerships later this year.”

GM said at the Bolt’s introduction in 2015 that the compact CUV would have a range of more than 200 miles (322 km) and cost about $30,000 after government rebates, but would not be more specific. Rival Tesla, which exclusively makes luxury EVs, answered with the promise of the Model 3, a car with a reported range of 215 miles (346 km).

GM also reveals today the Bolt will cost $37,500, before federal tax credits of up to $7,500. The Model 3, due late next year, is expected to cost $35,000. Both EVs seat five passengers.

The Bolt’s EV range is estimated by the EPA.

GM is banking on the Bolt to help transform its business. While not expected to be a volume-seller, the car will underpin new-mobility ventures for the Detroit automaker including car-sharing, ride-hailing and autonomous technology.

The Bolt has drawn the attention of EV lovers, including Apple co-founder Steve Wozniak who plans to trade in his six-figure Tesla Model S for one when it becomes available. Wozniak behind the wheel would be a ringing endorsement for the Bolt and a big marketing win for GM.
