Envision: The China-made compact crossover was freshened for the 2019 model year and repositioned with a starting price decrease of up to $2,000. The freshening gave the 2019 model Buick's updated grille with a winged emblem and new available LED headlights. Buick also enhanced the performance of the available 2.0-liter turbo engine by pairing it with a nine-speed automatic transmission and increasing torque by 35 pound-feet, to 295 pound-feet. A redesign is expected in 2020.

Enclave: A redesign of the large crossover for the 2018 model year and the addition of an Avenir trim are increasing sales and average transaction prices for Buick. Sales through June were up 15 percent, while ATPs have increased about $5,000, according to the company. Aside from some likely tweaks to trim levels, don't expect too many changes until a freshening of the vehicle in 2021.

EVs: Behind Chevrolet, Buick was expected to be GM's next brand to embrace all-electric vehicles in the U.S. However, due to a lack of domestic demand and the company's impending loss of federal tax credits , those plans may have been pushed back, if not eliminated, until GM's next-gen EV platform is released beginning in 2021. The brand is still expected to adopt several EV models for China, but a Chevy Bolt-based EV — previously expected as early as next year — may no longer show up in the U.S. If it does come stateside, it could be a Chevrolet, which already has an established network of dealers equipped for EVs.
