About Buick Lacrosse

The third generation LaCrosse debuted at the 2015 LA Auto Show as a 2017 model using E2XX platform shared with the 2016–present Chevrolet Impala. The platform switch reduced its weight by about 300 pounds (140 kg), despite slightly growing in length and width. The weight reduction was achieved by use of high-strength steels and better sound-absorbing material. The car is powered by a GM Small Gasoline Engine and GM Ecotec engine in China for tax credit purposes and by a Fourth Generation GM High Feature engine in North America. Starting 2018, the LaCrosse comes standard with an eAssist drivetrain, consisting of a mild hybrid 20-kilowatt (27 hp) electric and 2.5-liter Ecotec gasoline engine sending power to the front wheels through a 6-speed automatic transmission. In order to make room for an upcoming new product in the Kansas City, KS facility, the production of the LaCrosse was moved from GM Fairfax Assembly to Detroit/Hamtramck Assembly.

The main difference between the North American and Chinese models sold is the drive system. Models sold in the Chinese market are front wheel drive vehicles compared to their American counterparts which are available in front wheel drive or all-wheel drive. (Source Wiki)
