GM's MPG overstatement could affect 2 million vehicles

Late last week, GM admitted that three of its large SUVs fuel economy window stickers did not match their actual efficiency ratings, and so the vehicles couldn't be sold. The stickers on the 2016 Chevy Traverse, GMC Acadia, and Buick Enclave said their ratings were one to two miles per gallon better than they should have been. Officially, the number of affected vehicles sits at about 60,000. But Consumer Reports makes a good point: what's up with all of the previous model year SUVs that are basically the same vehicle? To wit: the 2016 model year vehicles are not substantially different than the 2015 or the 2014, or even going all the way back to 2007. On the EPA's fuel economy website, all of these older models will "have better stated fuel economy numbers than the new vehicles in GM's dealerships," Consumer Reports noted. CR's best point, and the one that makes the 60,000 number potentially grow to 2 million if all of the vehicles built on this platform are affected, is that "[i]t seems unlikely that the company would change the powertrain on these carryover models so late in their model cycles in a way that would cause a dramatic, negative impact on fuel economy." GM says that earlier model year SUVs are not affected and the EPA did not respond to CR's question about the potential for more discrepancies. We've seen automakers reverse course before, so if GM has to come out with a mea culpa soon, don't be surprised. GM is rushing corrected stickers to dealers so that the SUVs can be sold again, but a fix for the already-sold vehicles could be trickier to solve.

2018 GMC Terrain loses the V6 and gains a diesel for an all-turbo lineup

You may have noticed that compact crossovers are kind of a big deal these days. After eight years on sale, GMC is finally getting a new version of its littlest ute, the Terrain, for 2018. And it can't arrive a moment too soon. The 2018 GMC Terrain made its debut tonight on the eve of the 2017 Detroit Auto Show. The 2018 Terrain looks to be completely new, and is now built on GM's D2XX platform. It again shares a platform and major components with the Chevrolet Equinox; like the 2018 Equinox, the Terrain will offer three engines, including two turbocharged gas four-cylinders and a turbodiesel four. The base 1.5-liter gas four makes 170 horsepower and 203 pound-feet of torque, while the 2.0-liter inline-four puts out 252 hp and 262 lb-ft. (The 2.0 basically takes the place of the 3.6-liter V6 offered in the outgoing Terrain.) GM's 1.6-liter diesel four will also be available, making 137 hp and 240 lb-ft of torque in this application. Both gas engines will be paired with nine-speed automatic transmissions, while the diesel gets a six-speed auto. No fuel-economy claims have been made, but we expect the new models to outdo the current versions, with the diesel reaching around 40 mpg on the EPA highway cycle. View 14 Photos The new Terrain's design is equally fresh and does a good job of differentiating it from the related Equinox, with details very reminiscent of the new GMC Acadia. The lighting elements are even more intricate here, with LEDs used for the daytime running lights and taillamps. GMC designers gave it the floating-roof look, which is successful aside from the odd placement of a trim badge at the base of the D-pillar. Terrains will again be available in SL, SLE, SLT, and range-topping Denali trim, with the latter featuring the signature satin chrome grille, chrome accents, and monochrome paint scheme GMC uses on all of its top-trim models. The interior sees an upgrade in materials and a more-thoughtful layout, with a new version of GM's Electronic Precision Shift gear selector using buttons and switches instead of a lever to open up more space on the center console. Both front- and all-wheel-drive models get a Traction Select system that will tune the shift points and throttle points for specific driving conditions via a knob at the rear of the console. On models equipped with all-wheel drive, a front-drive mode disconnects the rear axle to improve fuel economy.

The GMC Hummer EV could spawn a smaller electric truck

Over 90,000 motorists have reserved a GMC Hummer EV, and the truck's relative popularity has convinced executives to consider launching a smaller and presumably more affordable model. While nothing is official yet, the Hummer EV's smaller sibling could be a midsize pickup. Citing "people familiar with the matter," Automotive News reported a smaller Hummer EV exists in the design studio that General Motors operates in California. There's no word on what it looks like yet, though it presumably borrows at least some of the rugged-looking styling cues that characterize the controversial, 9,200-pound truck. Interestingly, the smaller model could bring the Hummer name to Europe. It's too early to provide technical specifications. The model hasn't received the proverbial green light for production but Automotive News added that it's a "priority project" and that it has "a good chance of going into production." If and when it does, it's reasonable to assume the truck will use the Ultium battery technology found under the full-size Hummer EV, among other electric models from General Motors. GMC hasn't commented on the report, and it hasn't announced plans to launch a second Hummer-branded electric pickup. If the report is accurate, the baby Hummer is at least a couple of years away from hitting showrooms. First, the Hummer EV SUV will enter production. We've been here before: a downward expansion is exactly how the now-defunct Hummer brand was born. The military-bred H1 spawned the H2 for 2002 and the H3 for 2006. An even smaller off-roader previewed by the 2008 HX concept was planned but ultimately canned. Related video: This content is hosted by a third party.
