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.

2020 Buick Encore, Encore GX set for Shanghai debut

Buick says it will debut the all-new 2020 Encore small crossover and new-for-China Encore GX compact crossover at the Buick Brand Night April 15 in Shanghai on the eve of Auto Shanghai 2019. They'll join the updated 2020 LaCrosse and LaCrosse Avenir sedans, which GM is discontinuing here in the U.S. Buick released a darkened teaser image of both vehicles in rear three-quarters view, though it's a little hard to tell which is which (we're going with the GX being the one on the right). It suggests the Encore gets more streamlined taillights that taper along the rear liftback, with some redesigned creases on the door panels and haunches. The latter don't appear to be present on the Encore GX, which Buick says is a new addition to the model series in China. Both will be offered with GM's new nine-speed Hydra-Matic and continuously variable transmissions, plus what Buick says will be "enhanced connectivity," including new technologies. They'll join the Envision and Enclave for China, which is Buick's largest market. First introduced in 2013, The Encore was last refreshed for 2017. It has been the top-selling Buick model in the U.S. for the past 3 years, with 93,073 sold last year, up 5.7% from 2017.

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.
