The Chevrolet Bolt, General Motors' electric hatchback for the masses, will be able to go 238 miles on a single charge.
The car beats the base rear-wheel-drive Tesla Model S, which can go 210 miles per charge but costs about $28,500 more.
The Bolt goes on sale later this year for about $37,500 before a $7,500 federal electric vehicle tax credit.
GM says the Bolt's range was determined in testing by the U.S. Environmental Protection Agency.
Tesla's lowest-cost Model S is $66,000 before the credit.
Late next year Tesla plans to start selling the more affordable Model 3.
At $35,000 before the credit, it will cost less than the Bolt and is expected to go 215 miles per charge.
