Cadillac customers in China will soon have a new powertrain option on two of brand’s SUV models. The luxury brand has revealed the 2021 XT5 and XT6 models with a new mild hybrid system. Due to strict emissions standards in China, GM has been aggressively adding electrifications to its local lineup.

Both the XT5 and XT6 will leverage a new 48-volt mild hybrid system that’s mated to a turbocharged 2.0-liter engine. Cadillac says the electrical assist boosts fuel economy in the XT5 by about 5-percent and 6-percent in the larger XT6. Based on the fuel economy estimates, both SUVs will be good for the mid-30 mpg range.

The mild hybrid system will be the predominant source of motivation when the SUVs take off from a stop. Otherwise, the mild hybrid will simply provide supplemental power during most conditions. GM has a similar system on other models in the Chinese market.

For those wondering, don’t expect to see these powertrain options arrive stateside. GM has already confirmed the powertrain is specifically for the Chinese market and there are no intentions of bringing it to North America. Both the XT5 and XT6 are built locally in China, which partially explains how they can have unique powertrains versus their U.S. counterparts.

An all-new Cadillac XT5 is not expected for at least a couple of years. The future of the XT6 is even less-known given it hasn’t been on the market long.
