Modular new work, talk about 1.5T three-cylinder engine

This is the first time Volvo has released a three-cylinder engine in its 91-year history, and the first of its kind is the new compact SUV - the XC40. Domestic consumers may still be unfamiliar with the XC40, but we can briefly understand it through the Lynk & Co 01. The two come from the same CMA platform, with strong genetic consistency from the powertrain to the chassis architecture. Volvo's 1.5T three-cylinder engine will also appear on the Lynk & Co 01 (the current version is only 2.0T). What kind of new machine is this?
