The Buick Electra-X concept shows off the upcoming Ultium-based EV.

Buick is developing an electric vehicle based on General Motors' Ultium platform and battery technology, and the Electra-X concept unveiled this week hints at future developments.

The Electra-X, which will premiere at a Buick-branded event in China in early June, follows Buick's Electra Concept (shown below), which was unveiled in 2020 and is described as an SUV styled according to the brand's latest design principles. According to Buick, these principles include clean, futuristic lines and a light and airy interior.

The concept will also feature Super Cruise driver assistance technology and a digital dash. No powertrain specs were mentioned, but previous Electra concepts have carried 583 horsepower and battery capacity for a range of over 400 miles.

The previous Electra Concept also used GM's Ultium Technology. Buick also introduced a self-driving minivan concept in 2021 that also used Ultium technology.

The new Electra-X concept is said to preview an electric vehicle specifically for China, but some aspects may also preview elements on Buick's EV that will be sold in the US. Buick has confirmed that two Ultium-based EVs will be in local showrooms by the end of 2023, both SUVs: one will be conventionally proportioned and the other will have more coupe-like proportions.

Don't be surprised if one or both cars bear the Electra name. The name had been a fixture in the Buick lineup for decades, first appearing in the 1959 model year and continuing through 1990.
