General Motors said it would launch a "record" 20 new or "refreshed" models in China in 2019 with an eye on "emerging opportunities in new energy vehicles (NEVs)".

About half of the models will be new nameplates for the Chinese range, developed using global vehicle design and engineering facilities. 

"China's vehicle market has entered a new era of high quality development, in which product and service excellence will be the key to sustained growth," said Matt Tsien, the president of GM China.

"[We] will continue to optimise our product mix, backed by our industry-leading technologies and adjacent services, and explore more opportunities in electrification and autonomous driving."

China has been GM's largest retail sales market since 2012. It is speeding product launches and brand upgrades and considering introduction of new technology such as Super Cruise and vehicle to everything (V2X) communications.

Infrastructure expansion continued in 2018 with a new campus at the Pan Asia Technical Automotive Center (PATAC), the SAIC-GM Battery Assembly Plant and a new joint venture with local partner SAIC in financial leasing services.

GM said it expected to exceed its five-year plan to launch 60 new or refreshed products between 2016 and 2020, including 10 NEVs. From 2021 to the end of 2023, the company will maintain momentum by doubling its number of China market NEVs.

GM delivered 3.64m vehicles in China in 2018, in the midst of a softening vehicle market. 

Cadillac sales surpassed 200,000 units for the first time in China as deliveries rose 17.2% year on year.

Cadillac plans one new model every six months to the end of 2020. 

Chevrolet's 2018 deliveries reached 523,395 units. Sales of the Equinox SUV rose by over half 50 percent and Malibu XL sedan volume rose one quarter year on year.

Buick sold more than 1m vehicles for a third year in its largest market. The Excelle GT sedan the most popular model.

Baojun booked sales of 839,612 units.

Wuling deliveries passed 1m for another year. GM claimed it maintained its dominant position in the contracting mini-commercial vehicle segment and continued to expand in passenger vehicles.
