Tesla remains the brand with the most sales of plug-in cars in the U.S. but General Motors is close and experienced more year-over-year growth to date.

Last month, GM’s two best sellers, the extended-range Chevrolet Volt and Bolt EV plus the discontinued Cadillac ELR, Cadillac CT6 PHEV, and discontinued Spark EV helped it edge out Tesla with 4,742 sales to 3,550 estimated of the Model S, X and 3.

For the year, Tesla retains a lead with 40,720 estimated sales to GM’s 38,692 – and these are all pure EVs whereas GM sells EVs and plug-in hybrids.

Although Tesla is expected to turn on mass Model 3 production that will leave GM in its wake, at this time stamp in history, GM has had a relatively better year in terms of sales growth.

Last year at this time, GM had sold just 24,597 of its Volt, Spark and ELR – far below the 38,692 count from more cars this year. By contrast, this time last year Tesla had delivered an estimated 38,584 Model S and X units through November and was heads above GM.

Leading GM’s charge is of course the much-discussed Bolt EV, the 238-mile range compact crossover purpose built to lead GM’s charge into the next decade with 20 new spinoffs across its model lines projected by 2023.

That GM succumbed to revealing even this much is a bit of informational extravagance from the automaker best known to say “we don’t discuss future product.”

But since others like BMW, Daimler, Tesla, VW Group, Nissan, Mitsubishi, and more are rushing to hype future product, perhaps it was not a breach of State Secrets for GM to say it will be right there too in the deferred near future of the 2020s.

By then regulations will be very strict in Europe, Japan, the biggest market of China driving the most development, and the U.S. possibly as well – assuming things are not sidetracked by lawmakers pulling the teeth from rules set under the Obama administration and now being reviewed.

Coming back to GM, its portfolio is still but a placeholder, and certainly it is not as gung ho as Tesla which is all-in, fighting for its future, and dedicated to pure EVs.

The Chevy Volt has actually had a very off-note year, and is down with 18,412 sales through Nov. 2017 versus 21,048 in Nov. 2016, and during the first year for the redesigned 53-mile EV range car.

The discontinued Spark EV is also all but gone, replaced by the Bolt and it added just 21 sales this year to GM’s tally. The axed Cadillac ELR also contributed but 17 leftovers likely at screaming discounts, and the Chinese-imported CT6 PHEV has helped with only 172 sales this year. Really, it is the Bolt’s 20,070 and Volt’s 18,412 sales this year that are holding down the GM fort.

Tesla meanwhile is swinging for the fences, but not as well as it would like. Down from last year, the Model S has delivered 21,700 units estimated through Nov. 2017, versus 23,856 through Nov. 2016. The Model X is up with 18,300 this year versus 14,728 last year and is therefore responsible for the 2,028-unit estimated year-to-date lead over GM because certainly the Model 3 is not helping much.

Sales of the Model 3 are estimated at 720 for the year, and it had its best month in November with 350 estimated deliveries. In an updated projection, CEO Elon Musk has said production is to ramp into the thousands in the first quarter of next year.

GM on the other hand is not expected to have any sales dynamos of the caliber Tesla is still predicting for the Model 3. It also does not advertise the Bolt and Volt much to speak of – less so the Volt, which rumors have said could be replaced with a crossover.

Whether this speaks of a willful act on GM’s part because it 1) may lose money on its plug-ins, or 2) does not really wish to threaten its gas-burning bread and butter cars, is an open question. Those allegations are floated regularly in articles and reader comments, but the official line is GM is all in.

And as for today’s snapshot in the first decade of plug-in growth, the main takeaway is GM is plugging away, has released more models, albeit less successful and indeed the Spark and ELR were canceled after their first couple years.

Compared to other makes, GM and Tesla are otherwise heads above. Nissan is the other big name in the ring but down this year, and its new Leaf will be here early next year and has been selling very well in overseas markets.

Other brands are also due to pour it on, and the trading of places will continue.

GM has been in on the ground floor with a slightly concealed implicit rivalry with Tesla – doing things very differently, but at this stage it is well up and says it will be there going forward as well.
