The all-new 2021 Buick Envision compact crossover is just about to launch in the U.S., but the vehicle has been on sale in China for roughly half a year. In China, the new Envision is offered in five trim levels called, in ascending order of price, Elite, Deluxe, Luxury and Limited S Sport Edition, and Avenir. These names seem reasonable enough, but they are all preceded by the rather curious 652T badge.
What exactly 652T means is not clear, and GM China has not responded requests for more information. However, we’re going to step out on a limb here and say that it’s highly likely that the “652” is an arbitrary number in reference to what’s under the hood.
Like in North America, the Chinese-market 2021 Buick Envision is powered by the turbocharged 2.0L I4 LSY gasoline engine rated at 237 horsepower and 258 pound-feet of torque. Meanwhile, the “T” in “652T” likely denotes turbo-charging.
It’s worth noting that that LSY engine was not used in the first-generation Envision, which is no longer on sale in the Americas but is still on sale in China. To differentiate between the two models, the older model is known simply as Buick Envision, while the all-new one is labeled Envision S.
The first-gen Envision is offered with two turbocharged gasoline engines, the 1.5L I4 LFV SIDI Ecotec unit rated at 166 horsepower and 184 pound-feet of torque, and the 2.0L I4 LTG SIDI Ecotec producing 256 horsepower and 295 pound-feet. Curiously, Chinese versions of this Envision with the 1.5L engine are badged 532T, while those with the 2.0L motor are badged 28T.
Though this does not explain what the 652T figure refers to, as the figure does not appear anywhere in the specification of the LSY engine, it does make us feel we’re in the right area. It’s also worth noting that the 652T nomenclature is not a reference to the vehicle’s torque output, which is currently used by Cadillac.
The 2021 Buick Envision is based on GM’s E2 platform, also used by the 2016 and newer Chevrolet Malibu and its various derivatives from former GM brands Holden (Commodore), Opel and Vauxhall (Insignia). The vehicle is produced by GM China (SAIC) at the Jinqiao plant in Shanghai, and was launched in the Chinese market in July of this year.
