For its first full sales year, the Chevy Bolt EV finished on par with a couple of the better years the Chevy Volt enjoyed, and fell just short from the Volt’s all-time high.

More specifically, the Bolt’s 23,297 sales for 2017 bridges the gap between the Volt’s 23,461 sales in 2012 and 23,094 sales in 2013, but is less than the gen-two Volt did its first year, last year, when it delivered 24,739 units.

That said, the Bolt surpassed the Volt relatively significantly for 2017, as the Volt’s 20,349 underwhelmed with a 17.7 percent decline.

Last month the Bolt also managed to raise the bar again with 3,227 deliveries versus the Volt’s 1,937 which was down 47.5 percent from 3,691 Volt deliveries last year. December is traditionally the strongest month for plug-in sales due to the closeness of the end of the tax year and ability to claim the federal tax credit,

The 238-mile EPA-rated range Bolt was launched last December with 579 sales in Oregon and California, and its staged rollout took place this year though early summer.

Chevrolet had said it would control the distribution better than the Volt’s rollout its first calendar year in 2011 had been. That promised car had left people in the lurch in cases and dealers unclear on the distribution timing, and 2011 saw a mere 7,671 Volt sales for this new kind of plug-in car with a Bowtie badge on the grille.

The Bolt benefitted from distribution lessons learned and from the Volt having prepped people on what to expect so its more than three-times the sales volume its first calendar year is the result.

It also appears to be benefitting from GM’s focus on it as the basis for 20 more EVs due by 2023 across GM’s brands as the Volt reportedly could be canceled after this generation runs its course.

A front-wheel-drive compact crossover, the Bolt is priced from $37,495 before incentives and has been in the top three best-selling plug-in list this year in the United States.

How it will do next year could be tempered by the arrival of the new Nissan Leaf, Tesla Model 3, and other vehicles on the horizon.

Analyst Alan Baum of Michigan does not project more than 25,000 for it next year, and until further notice thinks it has flattened out.

Of course that could change, and the Bolt could keep rising. Time will tell.
