GM has clearly not learned from their bankruptcy. For a few years they built solid well designed vehicles in different styles to satisfy many drivers. Now, however, they offer only SUV’s from Buick and seem determined to bury cars with gasoline engines. In my opinion these will prove to be fatal mistakes.
Unfortunately, Buick sedans (and sedans in general) aren’t nearly as popular as they used to be in the U.S. The last generation U.S. Regal's best sales year was only around 14,000 units and that included the wagon. The last generation U.S. LaCrosse's best sales year was only 20,000 units. Despite lots of competition in the crossover/SUV space, the Encore, Encore GX, Envision and Enclave all did notably better.
So far this year, U.S. Buick sales are up quite a bit versus same period last year. Overall U.S. Buick sales are up 68% with Envision up 153% Encore GX up 110%, and Enclave up 20%. The discontinued Encore's sales are down but the Envista (Encore replacement) is due out soon and should significantly add to Buick's sales numbers.
