Does Buick Have a Hybrid?
As of the 2024 through 2026 model years, Buick does not offer a hybrid, plug-in hybrid (PHEV), or conventional gas-electric hybrid vehicle in its North American dealership lineup. While General Motors previously engineered mild-hybrid Buick sedans utilizing eAssist technology, the brand current domestic portfolio consists entirely of gasoline-powered turbocharged crossovers and SUVs. However, in international markets such as China, Buick manufactures and markets a diverse roster of plug-in hybrids and full hybrids, including the Buick GL8 luxury MPV. In North America, General Motors has strategically chosen to bypass traditional hybrids for the Buick marque, focusing resources instead on transition architectures and all-electric vehicles under the Buick Electra nameplate.
The History of Buick eAssist Mild-Hybrid Technology
While Buick currently lacks a hybrid powertrain in the United States and Canada, the brand was an early pioneer in mild-hybrid engineering with its proprietary eAssist system. Introduced on the 2012 Buick LaCrosse and Regal sedans, eAssist paired a 2.4-liter four-cylinder EcoTec gasoline engine with a compact air-cooled lithium-ion battery pack and a 15-kilowatt electric motor-generator. Unlike full hybrids manufactured by Toyota or Honda, eAssist could not propel the vehicle on pure electric power alone; instead, it provided electric torque assistance during heavy acceleration and enabled smooth start-stop engine shutoff at traffic signals.
The eAssist technology delivered a noticeable twenty-five percent improvement in city fuel economy, allowing a full-size luxury sedan to achieve up to thirty-six miles per gallon on the highway. Buick later reintroduced an updated version of eAssist on the 2018 LaCrosse paired with a 2.5-liter engine. However, as consumer buying preferences decisively abandoned traditional four-door passenger sedans in favor of high-riding crossover utility vehicles, General Motors discontinued its domestic sedan lineup, retiring the eAssist hybrid architecture along with them.
The table below outlines historical Buick mild-hybrid production models and their engineering specifications.
| Buick Model | Production Years | Powertrain Configuration | EPA Fuel Economy (City/Hwy) |
|---|---|---|---|
| Buick LaCrosse eAssist | 2012 - 2016 | 2.4L I4 + 15kW Motor (Mild-Hybrid) | 25 City / 36 Highway MPG |
| Buick Regal eAssist | 2012 - 2014 | 2.4L I4 + 15kW Motor (Mild-Hybrid) | 25 City / 36 Highway MPG |
| Buick LaCrosse eAssist (Gen 2) | 2018 - 2019 | 2.5L I4 + 20kW Motor (Mild-Hybrid) | 25 City / 35 Highway MPG |
| Buick GL8 PHEV (China Market) | 2024 - Present | 1.5L Turbo + Dual Electric Motors | Over 600 miles total combined range |
While historical mild-hybrids achieved respectable highway mileage, modern Buick buyers must look to standard turbo gas models or EV platforms.
Current North American Lineup and Future Electrification Strategy
Today, Buick North American showroom inventory is anchored by four distinct internal combustion crossover SUVs: the compact Envista, the subcompact Encore GX, the compact Envision, and the three-row midsize Enclave. Each of these models is powered by modern small-displacement turbocharged gasoline engines paired with nine-speed automatic or continuously variable transmissions. While these engines deliver competitive fuel efficiency in their respective classes, none feature hybrid battery assist or plug-in charging capabilities for North American consumers.
Looking forward, General Motors corporate strategy for Buick in North America has centered around full battery electric vehicles (BEVs) utilizing GM Ultium modular battery platform under the historic Electra moniker. Concept models such as the Buick Electra E5 and Wildcat show how luxury electric crossovers will redefine the badge. However, with shifting market adoption rates, GM leadership has hinted at potentially introducing plug-in hybrid options to bridge the gap between traditional combustion models and pure electric vehicles across North American brands.
