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.

Meet the Buick Velite 7, the Chevy Bolt's Chinese cousin

The Buick Velite 7 has officially been revealed after having been leaked and spied a few months ago. The name derives from Buick's line of electrified models it sells in China, of course the design shows it's most closely related to the Chevy Bolt EV. Buick hasn't revealed many details about it, and only one photo, but we do get to see it and we also have a range estimate. The range estimate is 500 kilometers on the NEDC cycle, which translates to 311 miles. That's actually less than the NEDC estimate for the Bolt EV, which is 565 kilometers or 351 miles, which increased for the 2020 model year from 520 kilometers or 323 miles. Of course NEDC figures tend to be much higher than EPA numbers, which rated the current Bolt EV at 259 miles and the previous version at 238. As such, we would expect this Buick to have an EPA range closer to 210 to 220 miles. We don't know what resulted in the lower range, but it could have something to do with additional weight or slightly worse aerodynamics. It could be both. Design-wise, the Buick is clearly based on the Bolt, but has a more aggressive front bumper and a trendy partially floating roof. It also seems to have a slightly boxier, taller profile, mainly because of the nose. Buick hasn't released any other details about the crossover, preferring to save them for the car's launch later this year. Since it seems so closely related to the Bolt, it probably has the same drivetrain: a single electric motor sending 200 horsepower and 266 pound-feet of torque to the front wheels via a single-speed transmission.

2018 Buick LaCrosse gets a mild hybrid model, lower price

Update: Buick provided us with horsepower and fuel economy figures. The text has been updated to reflect this. Buick is rolling out a variety of updates for the 2018 LaCrosse, including a new mild eAssist hybrid. Like the previous generation LaCrosse and Regal eAssist models, this one features a small electric motor and an equally small battery pack that together augment rather than supplant the gasoline engine. The motor, attached to a 2.5-liter four-cylinder engine, helps to make takeoffs smoother and provide additional torque on demand. The gasoline engine still does the majority of the work, though. Combined, the powertrain produces 194 horsepower and 187 pound-feet of torque. It will also allow the LaCrosse to get 25 mpg in the city, and 35 mpg on the highway. While the electric powertrain doesn't provide primary propulsion, it does come with other benefits. The small battery means the LaCrosse maintains a folding rear seat. The battery also provides power to accessories when the engine shuts off at a standstill. This mild hybrid powertrain will be the standard engine for all 2018 LaCrosses, and they come with a lower base price. The 2018 model will start at $31,415, which is about $1,500 less than the lowest priced 2017 V6 LaCrosse. The V6 will still be available as an option, and Buick has updated it, too. The 2018 V6 models will also all come with a new 9-speed automatic transmission. The new LaCrosses will go on sale this fall. Related Video: Image Credit: Buick Green Buick Hybrid Luxury Sedan
