General Motors China held an electrification workshop in Shanghai to showcase its new energy vehicles and advanced powertrains. The workshop also highlighted GM China’s long-term vehicle electrification strategy. GM China will hold similar electrification workshops in Beijing and Guangzhou.
In China, GM and its joint ventures currently offer light electrification technology with the Buick LaCrosse eAssist; full hybrid technology with the Cadillac Escalade Hybrid; extended-range electric vehicle technology with the Chevrolet Volt; and battery-electric vehicle technology with the locally produced Sail SPRINGO EV (earlier post).
The new Buick LaCrosse eAssist model, which will be launched in China next month, is powered by a hybrid powertrain that combines a 2.4L SIDI engine, a customized 6-speed transmission, a 15-kW electric motor and lithium-ion batteries. It consumes 5.2 liters of fuel per 100 km (45 mpgUS) at a constant 90 km/h (56 mph) and 7.2 liters of fuel per 100 km (32.7 mpgUS) under combined road conditions, giving it a fuel economy advantage of 20% over similar models with conventional internal combustion engines.
The Chevrolet Volt is the first extended-range electric vehicle offered in China. It can travel up to 80 km (50 miles) on electric power. When its battery is depleted, its range-extending engine kicks in to take the Volt another 490 km (304 miles).
The Sail SPRINGO EV is an all-electric vehicle that can go more than 130 km (81 miles) on a single charge, with less than 15 kWh consumed for every 100 km. It generates 510 N·m (376 lb-ft) of peak torque and has a top speed of 130 km/h (81 mph).
