GM unveils nine-speed automatic gearbox in China
General Motors says it plans to install its new nine-speed automatic transmissions in a number of vehicles produced in China to meet the country's increasingly strict fuel economy standards.
By 2020, the transmission will be used in 13 Chinese models under the Chevrolet, Buick and Cadillac brands.
The first vehicle with the transmission in China will be the Chevrolet Equinox crossover, which will hit the Chinese market this year.
The transmission was tested in a variety of road conditions worldwide, including China. It improves fuel efficiency up to 2 percent from a six-speed transmission, GM says.
The transmission also is designed to accommodate start-stop systems, which further improves fuel economy.
Nearly 78 percent of GM models sold in China are equipped with start-stop systems, according to SAIC-GM, GM's passenger vehicle joint venture in China.
The central government requires automakers to cut their average fleet fuel consumption to 5 liters per 100 km (47 mpg) by 2020, from 6.9 liters per 100 km (34 mpg) in 2015.
