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.

These were our favorite cars of 2022

Favorite cars is different than best cars. The idea of "best" can speak to value and overall competitiveness in a given vehicle segment. There's lots of objectivity involved and to do a "best" list right, one really must be very thorough and as scientific as possible. This is not that list. This is about our favorites, so objectivity be damned. If we liked a Challenger Hellcat because it made loud noises or a Honda Odyssey because it made for a particularly special family vacation, fair game. These were the cars that most spoke to our collection of editors and the ones that stayed in our minds and hung in our hearts long after they left our driveway. — Senior Editor James Riswick 2022 GMC Hummer EV Senior Editor, Green, John Beltz Snyder: I didn't particularly expect to like the new Hummer. I wasn't a fan of the Hummer H2 or H3, so I wasn't automatically enthusiastic about this electric reboot. Fast EVs aren't hard to come by — and, in fact, may be too easy to come by — so its performance specs weren't enough to win me over. Despite videos to the contrary, pickups aren't my favorite vehicular format. And its excessive size and weight turned me off ... until I finally got behind the wheel.  This thing is wildly entertaining to drive. Watts to Freedom launch control is a neat party trick, sure, but the novelty wears off quickly. The novelty of Crab Walk, however, has staying power. The rear-wheel steering makes this behemoth feel much smaller than it is — the maneuverability is incredible, and useful. The air suspension provides tons of clearance, including a ridiculously high-riding Extract mode. I can't wait for lesser versions of the Hummer to make their way to market. Give me less power (for less money), but keep the off-road tricks onboard, and I'll be a happy camper. Senior Editor, Consumer, Jeremy Korzeniewski: If I could afford to put one of these in my driveway, I would. Sadly, I can't, so I won't (What's that, Janet? I got the lyric wrong?). Still, I love the dumb thing. Thankfully, I have another choice down below. 2022 Porsche 911 GT3 Associate Editor Byron Hurd: Yeah, duh, Porsches are good. But there's good, and then there's GT3. This is the feeling every performance-oriented RWD tuner is trying to replicate. This is hard, precise, surgical and immensely satisfying. To begin to explore this car on a public road is by itself an admission that you believe yourself to be above the rules as they apply to normal drivers.

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.
