#GmcAcadia

Revealed overnight before its in-person, on-stage performance at the 2016 North American International Auto Show, the 2017 GMC Acadia will gain a new, 2.5-liter four-cylinder engine with start/stop tech and lose nearly 700 pounds of heft.

The former Lambda-based crossover also sees a significant realignment in size thanks to a switch to the new Chi platform that underpins the new Cadillac XT5. The Acadia’s wheelbase shrinks by over 6 inches, length by 7 inches, and width by 3 inches.

Nine years ago, General Motors began selling two different vehicles off its full-size Lambda platform, the GMC Acadia and Saturn Outlook.

Remember the Outlook? Of course you don’t.

By 2007, GM was also selling the Buick Enclave. By the end of 2008, GM added the Chevrolet Traverse.

Now it’s late 2015. GM is still selling the first generation of their Lambda platform crossovers. A lot of them.

GM also continues to sell the six-year-old versions of their Theta platform crossovers, as well. A lot of them. More than they’ve ever sold before.

During the summer of 2007, I worked for Enterprise Rent-A-Car, and it was my job to drive the cars between locations. This was an excellent job when I was approximately 17, because a) I got to drive all these cool cars, and b) what the hell else was I going to do? Read?

Back then, I remember that the very coolest car we had in our fleet was the Buick Enclave. This may seem odd to those of you out there reading this, but it was true: the Enclave was very cool. Not only had it just come out, but it was a luxury car, and by God it wasn’t some stupid General Motors fake attempt at a luxury car. It was an actual, decent, legitimately good luxury car. It was among the first signs of a “new” General Motors.

General Motors has sold 189,354 copies of its big Lambda-platform crossovers in the United States this year. Combined sales of the Buick Enclave, Chevrolet Traverse, and GMC Acadia have risen by a scant 137 units through the first nine months of 2014.

GM’s six full-size, body-on-frame, pickup-based SUVs, on the other hand, have collectively increased their U.S. volume by 22%, a gain of 32,652 sales, to 183,080 units in total.

These nine nameplates have generated 17% of GM’s 2.2 million year-to-date sales.
