General Motors' Buick brand will launch its first electric model based on the Ultium platform in China next week, in what could be one of the most anticipated EV offerings from a foreign brand here.

Buick will launch the Electra E5, a large five-seat all-electric SUV, in China on April 13 and will be offered in standard, long-range and Avenir four-wheel-drive versions, SAIC-GM, GM's joint venture in China, announced today.

The Electra E5 features the Pure Design concept, the new generation Virtual Cockpit System (VCS), and Buick eConnect network connectivity technology, SAIC-GM said.

The model will feature exclusive battery cells with a CLTC range of up to 620 km and can consume as little as 13.5 kWh per 100 km.

Its Avenir 4WD version will feature the Ultium 8-in-1 electric drive system with a permanent magnet synchronous motor in the front and an induction asynchronous motor in the rear.

The Avenir version uses a battery pack with a capacity of 80 kWh, offering strong performance and range, SAIC said.

China's Ministry of Industry and Information Technology released a list of models that will be allowed to be sold in China for public comment last November 16, and the Buick Electra was included.

The Electra E5, which entered the catalog at the time, has a single electric motor with 180 kW of peak power and a top speed of 180 km per hour.

The Buick Electra E5 measures 4,892 mm in length, 1,905 mm in width and 1,655 mm in height, and has a wheelbase of 2,954 mm, the filing data show.

Its power battery is a ternary lithium battery, and the supplier is a joint venture between Chinese power battery giant and SAIC.

The battery pack has a capacity of 68.4 kWh and will give the vehicle a CLTC range of 545 km.

Last December 19, Buick began warming up for the Electra E5, saying the model would be launched soon.

On December 28, Buick saw the first pilot vehicles of the Electra E5 roll off the line at the Ultium plant in Wuhan, Hubei province, central China.
