BEIJING (AP) — Global automakers and EV startups unveiled new models and concept cars at China’s largest auto show on Thursday, with a focus on the nation’s transformation into a major market and production base for digitally connected, new-energy vehicles.

Toyota and Nissan both announced tie-ups with major Chinese technology companies as they strive to meet customer demand for AI-enabled online connectivity in cars, from social media apps to autonomous driving features.

Electric vehicles accounted for about a quarter of all auto sales in China last year. Hybrids, which have trailed EVs, are expected to be a growing segment going forward.

China’s largest EV maker, BYD, showed off two “dual-mode” plug-in cars that can run either solely on electricity or as hybrids. The other is a hybrid off-road SUV from its luxury Yangwang brand in the 1 million yuan-plus ($140,000) range.
