After selling 758,000 in the second quarter of 2018, GM is celebrating strong performances across its brands in the first half of 2018.

Even though the industry is performing well in general, both GMC and Chevy beat industry trends. The latter's sales grew 6% and the former's grew 7% in the second quarter, while the industry-wide trend was only a one to two percent rise.

Cadillac, too, beat industry trends, with sales rising 3% and GM's overall sales grew 5%. That means an estimated market share of 16.6%, which accounts for a 0.5% increase.

While the reasons for the sales momentum are varied, record crossover sales at Chevrolet contributed disproportionately to the increase there. The second quarter was the best-ever for both the Trax and the Traverse and it was the best ever first half for the Equinox.

Meanwhile, the pickups and SUVs did what pickups and SUVs do best and sold in a manner that could be described as hotcake-like. With more than 366,000 units moving in Q2, sales were up 18%, making this their strongest quarter since 2007.

"Customers are buying with confidence because the economy is strong and they expect it to remain strong," said Kurt McNeil, U.S. VP of Sales Operations. "GM is in a fantastic position with so many new crossovers at all four of our brands, the industry's only three-truck pickup strategy and clear leadership in large SUVs."
