TFL has published a write up on the Buick Envision, as well as an "Everything You Ever Wanted to Know" on the 2016 Buick Envision.
The Envision is powered by a 2.0-liter turbocharged four-cylinder engine that produces 252 horsepower and 260 lb-ft of torque. That engine is connected to a 6-speed automatic transmission. Start/Stop technology contributes to the engine's efficiency, and Buick's first active Twin Clutch AWD system will strengthen the crossover's performance in a variety of road conditions.
TFL has positive impressions of the interior, although it's worth noting that they haven't actually driven an Envision yet.
The Envision has a full slate of safety and driver's aid technologies. These include: 10 standard air bags, available Automatic Park Assist, available Surround Vision camera system and Lane Keep Assist (standard) among others.
