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.

Avista concept shows Buick's performance potential [w/video]

With names like Wildcat and Riviera in its past, Buick knows how to make a good-looking performance machine. It's just been awhile. But the Avista concept revealed Sunday night ahead of the Detroit Auto Show suggests Buick's sporting heritage might be more than relegated to grainy photos. The Avista is a 2+2 sports coupe running a twin-turbocharged V6 cranking out 400 horsepower through the rear wheels. Look familiar? It should, as it reprises many of the design cues from Buick's last show-stealer, the Avenir, which debuted a year ago in Detroit. "The Avista embodies the dynamic soul of Buick," said Duncan Aldred, vice president of global Buick sales, service, and marketing. "It is a modern expression of the brand's heritage of sophisticated performance, communicated with beautiful elegance." The front end features a prominent grille with Buick's newly colored tr-shield as the centerpiece. It's flanked by wings that stretch out horizontally and edgy headlights that portend the appearance of future Buicks. There's an aggressive fascia, chrome-trimmed vents, and it all rolls on 20-inch wheels. The Avista has a 110.7-inch wheelbase (which is the same as the Chevy Camaro), and the tracks measure 63 inches in front and 62.9 inches in back, which Buick says makes for a sporty stance. The B-pillarless cabin conjures the open layout of great boulevard cruisers of days gone by. It's done up in gray leather punctuated with carbon-fiber and aluminum accents. Yep, Buick does know how to do performance. In case you forgot, the Avista is a strong reminder of the past, and it offers hope for the brand's future. Watch the live unveiling in the video below. Buick Introduces Avista Concept Design elegance, performance heritage conveyed in turbocharged 2+2 coupe DETROIT – Ahead of its public debut at the North American International Auto Show, Buick today revealed the Avista concept – a 2+2 coupe that pushes the brand's contemporary design ethos and rekindles its historic performance roots. A sleek, sweeping proportion is the foundation for this vision of a contemporary grand tourer, with a 400-horsepower twin-turbocharged V-6 driving the rear wheels and a driver-focused cockpit offering a comfortable, connected center of control. "The Avista embodies the dynamic soul of Buick," said Duncan Aldred, vice president of Global Buick Sales, Service and Marketing.

Buick unveils new Verano hatchback in Guangzhou

This is a Buick Verano. We know, it doesn't look like a Verano – or at least not the version we get here. In fact it looks more like the new Opel Astra with a Buick grille. Which makes sense, because that's pretty much what it is. The vehicle you're looking at is the new Buick Verano Hatchback, unveiled just days ago at the Guangzhou Motor Show in China – arguably the only market that matters as much to the brand as the United States. Like the sedan revealed this past April in Shanghai, the hatchback is a newer model than the US-market version, based on the new Opel Astra, but with that signature waterfall grille. Otherwise, it looks virtually identical to the version sold as an Opel in Europe and a Vauxhall in the UK. Buick will be offering two versions of the Verano hatch in China. The base model pairs a 1.5-liter inline four good for 117 horsepower and 108 pound-feet of torque to a six-speed dual-clutch transmission. The sportier Verano GS packs a more potent version of the same engine, rated at 166 hp and 184 pound-feet and paired to a seven-speed DSG. That's enough to propel it to 62 in 8.8 seconds, but displacing less than 1.6 liters, both versions come in under the Chinese tax threshold so they're taxed 50-percent less. Between the Verano and Astra, we've now seen this new model in three different body-styles being sold in markets around the world. The sedans, hatchbacks, and wagons seem to be proliferating like so many jackrabbits, but keep hopping away just out of reach. So here's hoping that the next leap it takes will be to US showrooms.
