General Motors (GM) and China’s SAIC Motor have signed off on a 20-year extension of their Chinese joint venture (JV), pushing the partnership out to 2047.

SAIC-GM has been operating in China’s automotive sector since 1997, with cumulative production and deliveries surpassing 20 million vehicles.

The venture built out full-cycle vehicle development capability early on.

Under the renewed terms, SAIC-GM will narrow its brand focus to Buick and Cadillac in the Chinese market.

The extension also commits the JV to launching a minimum of 30 new energy vehicles by 2030, alongside wider deployment of China-developed technology tailored to Chinese buyers.

Central to this push is Electra, Buick’s premium new energy vehicle (NEV) sub-brand introduced in 2025.

It runs on the Xiao Yao super architecture, which the company positions as the first platform of its kind developed under Chinese leadership.

Within a year of debuting, the Electra range has grown to span sedans, SUVs and MPVs, spread across battery-electric, plug-in hybrid and extended-range electric variants.

The line’s strongest performer, the E7, moved more than 10,000 units in its debut month.

That model is now poised to lead SAIC-GM’s premium NEV push beyond China, with the E7 becoming the venture’s first premium NEV to enter overseas markets.

Rollout in selected international markets is scheduled to begin in October.

The JV news follows a run of updates from GM.

Late last month, the automaker raised its full-year 2026 earnings guidance for the second time this year, after second-quarter results showed revenue of $48.02bn.

Net income attributable to stockholders came in at $1.30bn for the quarter ended 30 June 2026, down 31.1% year-on-year.

Revenue itself rose 1.9% over the same period, while adjusted EBIT climbed 29.8% to $3.94bn – lifting the adjusted EBIT margin to 8.2%, up from 6.4% a year earlier.

That same month, GM also entered into a strategic customer agreement with Micron Technology, securing longer-term supply of memory and storage components the automaker considers key to vehicle manufacturing and high-volume deliveries.
