The company has sold 12,249 Bolts since the EV first arrived late last year in select markets.

General Motors has announced that the Chevrolet Bolt is now available by order or in stock at showrooms nationwide.The company has sold 11,670 Bolt EVs this year and 12,249 since the start of sales in December, slowly expanding across the country from an initial launch limited to California and Oregon.

The Bolt was billed as the "first affordable long-range electric car," with an entry price of $37,495 and an EPA-estimated 238 miles of range on a single charge.

Bolt sales this year are only slightly ahead of the Nissan Leaf's 9,685 US-market deliveries through the end of August. The Japanese automaker presumably expects the next-generation Leaf -- unveiled this week -- to retake the throne when it arrives early next year with a longer 150-mile range and cheaper price tag of $30,875.

The Bolt also faces pressure from the Tesla Model 3 next year as the California-based automaker begins to ramp up production volume to clear a backlog of nearly a half million pre-orders.
