Buick Avenir concept struts into Motown

We love auto show surprises, and Buick has already gifted us a sparkly package on the eve of the 2015 Detroit Auto Show. Dubbed Avenir, this four-door concept is said to signal the future of the Trishield brand by previewing a possible flagship sedan. Incorporating time-honored Buick design hallmarks like the sweep-spear profile, Ventiports, and even a subtle boattail rear-end, the four-place sedan is powered by a surprisingly real-world powertrain – namely a next-generation V6 with cylinder deactivation and stop/start, with the most interesting part of the driveline arguably being a "twin-clutch all-wheel-drive system" and a nine-speed automatic gearbox with paddle shifters. Make no mistake, this is a big car. At 204.5 inches long, it's longer than a standard-wheelbase Cadillac Escalade – a span that's emphasized by the car's long hood and waterfall grille – though it's not quite as wide. While clearly a showcar, the beautifully crafted interior looks largely produceable, including attributes like a next-generation 12-inch touchscreen infotainment system and 4G LTE wifi, but we suspect a production car would pick up a third rear seatbelt and give away some of its flowing contours that are said to have been "inspired by nature and sea waves receding on a beach." No word yet on whether there's actually a showroom future for a car like this – it could simply be an exercise designed to test the waters for a next-generation LaCrosse. After all, sedans aren't exactly popular concept fodder these days, especially as crossovers continue to eat into traditional sedan sales in many of the world's markets. However, China still loves the coddling rear seats of a proper four-door sedan (which in this case include silk and bamboo elements), and with a majority of Buick sales happening in the People's Republic, the Asian nation controls the destiny of this General Motors brand. Said another way? Anything is possible, especially with General Motors known to be working on a large flagship sedan for Cadillac already – the Avenir is reportedly based on the same Omega architecture that will underpin the forthcoming CT6. What do you think? Is this a promising direction for the resurgent Buick? Scroll through our gallery, check out the video, and then have your say in Comments.

2014 Buick Regal gets the party rolling in NY

Although the first day of the 2013 New York Auto Show kicks off bright and early this morning, Buick got a jump on the competition by unveiling the 2014 Buick Regal lineup last night. While the Regal received many upgrades for the 2014 model year, most of our attention was focused on the sedan's drivetrain.
When the new Regal hits dealers this fall, buyers opting for the new Regal Turbo will be welcomed by an additional 39 horsepower and 35 pound-feet of torque from the 2.0-liter turbo engine; the 2014 Regal GS now features the same output of 259 hp and 295 lb-ft, meaning that it has actually lost 11 hp over the 2013 model year. Buick says the reason for the GS' power loss comes from the fact that the newly available all-wheel-drive system forced the car to use a smaller diameter exhaust system, but representatives on hand assured us that the reduction of horsepower won't affect the car's performance and could even help improve fuel economy. And who knows? Maybe downgrading the power of the Regal GS also helps create a little breathing room for a future Grand National or GNX model...
Although the power under the hood is now the same, it is still impossible to confuse the two cars from the outside. Minor updates give both a fresher look, but the Regal GS has an unmistakeable aggression to it. The GS' interior also helps it stand apart from lower Regal trim levels with an eight-inch configurable gauge cluster similar to what is offered in the 2014 LaCrosse. The cabin of the Regal wasn't given an extensive makeover like the LaCrosse received, but the upgraded IntelliLink infotainment system and the cleaner center stack and steering wheel controls are appreciated changes.

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.
