Buick’s Electra GS plug-in hybrid sedan has appeared in China’s latest vehicle regulatory filing, providing the first detailed look at the fastback model’s design, powertrain and battery suppliers ahead of its expected market introduction.
China’s Ministry of Industry and Information Technology (MIIT) included three Electra GS variants in its 413th batch of vehicle filings, published for public consultation from November 4 to November 10. All three versions are manufactured by SAIC-GM, Buick’s joint venture with General Motors.
Three Powertrain Configurations Listed
The regulatory documents identify two petrol engine output levels paired with a common electric motor specification.
All three variants use an electric motor producing up to 165 kW (221 hp). Their 1.5-litre engines have rated outputs of either 72 kW or 115 kW, depending on the version.
Each configuration also uses a lithium iron phosphate (LFP) battery. One variant features cells supplied by Rept Battero Energy, while the other two use cells from Zenergy. SAIC-GM’s subsidiary manufactures the battery packs.
The filing does not disclose battery capacity or the vehicle’s electric-only driving range.
Fastback Design and LiDAR Options
Images released with the filing show a five-seat sedan with a coupe-like fastback roofline. Exterior features include slim headlights, a full-width rear light assembly, semi-hidden door handles and Electra GS badging.
The vehicle measures 4,979 mm in length and 1,914 mm in width, with a wheelbase of 2,865 mm. Its height varies slightly across the three registered configurations.
The filing images also show a roof-mounted LiDAR sensor, although the equipment list includes an alternative configuration without one. Other available options include different rear spoilers, brake calipers and exterior trim elements.
MIIT has not identified the driver-assistance system supplier or specified its capabilities. Pricing, final trim levels and launch timing have also not been announced.
Buick Continues Expanding Its China NEV Lineup
The Electra GS filing comes as Buick continues to refresh its new energy vehicle portfolio in China.
On September 23, the brand introduced an updated Electra E7 plug-in hybrid SUV, around five months after the model’s initial launch. The revision focused on its powertrain and driver-assistance equipment, with the Pro version combining a 1.5-litre turbocharged engine and advanced driver-assistance features.
The Electra GS will add a sedan option to Buick’s expanding electrified lineup, although its final specifications and market positioning remain subject to further announcements.
