The Buick Envision got a handful of small updates for 2019. The styling was updated to bring it in line with the remainder of Buick's vehicles. The available turbocharged engine upgrade gets a remarkable increase in torque along with a 9-speed automatic transmission. Drivers can also now deactivate the automatic stop and start system. The 2019 Regal acquired a range-topping Buick Avenir trim level. For 2019, the Encore's various trims were reduced. The Preferred II and Premium were also discontinued. The Buick powertrains remain consistent for the 2019 Encore. The 2019 LaCrosse added a blacked out grille. The LaCrosse comes with the existing V6 engine but gained 19-inch wheels and subtle exterior trim details. The 2019 Buick Enclave remains consistent with last year’s model, as it was entirely redesigned for 2018. The Enclave keeps its whisper-quiet cabin and luxury three-row layout along with several features that come standard.
