General Motors (NYSE:GM) said that its U.S. sales rose 4.6% in the second quarter on strong sales of its trucks and its all-new lineup of crossover SUVs. 

GM no longer reports its U.S. sales results on a monthly basis. But Automotive News estimates that GM's U.S. sales rose 5.7% in June, outpacing the overall U.S. market's 5.2% gain.

Year to date, GM's U.S. sales are up 4.2%.

High and low points from GM's second-quarter sales report

The high points:

  • GM's overall average transaction price (ATP) was about $35,500 in the quarter, up roughly $300 from the year-ago period.
  • That ATP gain was helped by GM's newest crossovers, the big Chevrolet Traverse and Buick Enclave. Both are all-new models that began arriving at dealers last fall, and both are selling well. Second-quarter sales of the Traverse and Enclave rose 30% and 25.4%, respectively, versus sales of their predecessors a year ago.
  • The new Traverse is selling at much better prices than its predecessor. GM said that its ATP was up almost $7,000 in the first half of the year, versus the year-ago period.
  • Sales of GM's crossovers as a group rose 5.8% from a year ago.
  • GM's big pickups, the Chevrolet Silverado and GMC Sierra, will be replaced by all-new versions for 2019. But sales of both remained strong in the second quarter, with the Silverado and Sierra up 15.7% and 20.4%, respectively, from a year ago.
  • GM's full-size pickup sales didn't quite outpace arch-rival Ford's in the second quarter, but they left FCA's Ram in the dust. GM sold 214,935 Silverados and Sierras in the quarter, versus 236,947 Ford F-Series and 129,575 Rams.
  • Cadillac sales rose 3%, and that wasn't just SUVs. Sales of the big XTS sedan, a popular "black car" fleet option that was overhauled for 2018, rose 36% in the second quarter. The well-regarded midsize CTS sedan gained 2.6% from a year ago.
  • GM's big truck-based SUVs are nearing the ends of their model lives, but sales of these highly profitable vehicles are still strong. Sales of the group rose 22% in the second quarter. Of note: Sales of the upscale GMC Yukon were up 17.5% year-over-year.

The low points:

  • While Cadillac's sales were up in the second quarter, the brand is still struggling. Its flagship CT6 sedan is a critics' darling, but GM sold just 2,427 in the quarter, down almost 19% from a year ago.
  • Buick sales fell 12%, hurt by one of GM's few crossover misses, the compact Envision. Sales of the made-in-China Envision fell 48% year over year.
  • Most of GM's sedans are struggling. That's no surprise given industrywide trends favoring crossovers over traditional cars. Sales of once-popular models like the Chevrolet Cruze and Malibu and the Buick LaCrosse were all down by double-digit percentages in the quarter.
  • Sales of the Chevrolet Camaro fell 36% to 13,588 in the second quarter. The Camaro was outsold by both of its traditional rivals, the Ford Mustang (23,264 sold) and FCA's Dodge Challenger (19,719 sold).
  • Sales of both of GM's vaunted electrified vehicles, the Chevrolet Volt and Bolt EV, fell 19.2% and 22.6%, respectively. GM said that global sales of the Bolt were up over 35% in the second quarter, but it hadn't yet released detailed figures as of press time.

The upshot: GM is executing well under the circumstances

There are some reasons for shareholders to be concerned -- notably the struggles of GM's upscale (and higher-margin) Buick and Cadillac brands. But there are more reasons to be encouraged: Most of GM's new crossovers are selling very well, at strong prices; full-size pickup sales were strong despite all-new models waiting in the wings; and demand has remained very strong for GM's hugely profitable big SUVs.

GM executives have said that 2018 should be a year of holding steady, with the crossovers generating strong profits while the company works to launch its new pickups (and after that, all-new versions of the big SUVs.) With the first half of the year now in the books, it looks to be playing out much as they expected.
