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.

GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.

Neil Young's 1953 Buick Roadmaster Skylark brings $400,000 at auction

Singer-songwriter Neil Young's extensive collection of model trains have fetched nearly $300,000 at auction, along with classic cars and musical equipment owned by the 72-year-old folk-rock icon. Young, a model train enthusiast for decades, offered more than 230 pieces at Julien's Auctions in Los Angeles from his collection of Lionel trains, including a custom-painted Commodore Vanderbilt 4-6-4 locomotive that sold for $10,000. Several cars that Young owns were also sold. A 1953 Buick code 76X Roadmaster Skylark convertible with a steering wheel hub that says, "Customized for Neil Young," went for $400,000, the auction house said on Saturday. Young, best known for his Woodstock-era songs as well as his work with the bands Buffalo Springfield and Crosby, Stills, Nash & Young has said the vast model train layouts at his California ranch helped him connect with his son Ben, who has cerebral palsy. Other items auctioned off on Saturday included some of Young's guitars, amplifiers and microphones. A portion of the proceeds will benefit the Bridge School in California, which Young's ex-wife Pegi Young co-founded in 1986 for children with severe speech and physical impairments.Reporting by Joseph AxRelated Video:
