The Buick Envision is back with a second generation for the 2021 model year. Styling is much more attractive than in the past, and there’s a new Avenir model for those who want extra luxury and flair. In other news, Buick has eliminated the anemic base engine and now offers exclusively a turbocharged 2.0-litre four-cylinder engine that serves up 252 horsepower and 295 pound-feet of torque.
