Buick Plug-in Hybrid Minivan Sets New Record

While Buick has streamlined its lineup to SUVs in North America, its “Bizarro” twin in China just achieved a feat that would make any road-tripper take notice. In late January 2026, the Buick GL8 LS PHEV officially set a new world record for the longest-range production plug-in hybrid (PHEV) minivan.

During an endurance test, the luxury hauler drove non-stop for 616.29 miles (991.79 kilometers). ^{Consequently, this performance effectively doubles the total range of most electric-only competitors and easily bests Western favorites like the Chrysler Pacifica Hybrid.}

The 1,000 km Challenge: Breaking the Record

The record-setting run targeted the “range anxiety” that still prevents many families from switching to electrified vehicles. By traveling nearly 1,000 kilometers on a single tank and charge, the GL8 LS PHEV proved that efficiency does not have to come at the cost of utility.

• The Route: A mix of highway and urban driving designed to simulate real-world travel.
• The Result: 616.29 miles (991.79 km) of continuous travel.
• Efficiency: Even after the battery hit 0%, the 1.5T engine maintained a steady fuel consumption of just 6.83 L/100 km.

Under the Hood: The “True Dragon” System

The secret to this record lies in Buick’s proprietary “True Dragon Plug-in Hybrid Pro” technology. This system utilizes a high-efficiency 1.5-liter turbocharged engine specifically tuned for the Miller cycle.

• Dual Motors: The P1 and P3 motor configuration delivers a combined 292 hp and 580 Nm of torque.
• Rapid Replenishment: The vehicle features 5C fast-charging technology, which allows the battery to surge from 30% to 80% in just 15 minutes.
• Smooth Transitions: A dedicated 2DHT (2-speed Dedicated Hybrid Transmission) ensures that the switch between electric and gas power is imperceptible to passengers.

Luxury on Wheels: The Avenir Experience

In China, the GL8 is not just a “soccer mom” van; it is a high-status executive shuttle. The 2026 Avenir trim level offers levels of refinement that rival private jets.

• The “Galaxy” Cockpit: A massive 30-inch curved 6K display powered by the Snapdragon 8775P chip.
• Rear Comfort: Second-row “Nappa leather” Captain’s chairs featuring 10-point massage, heating, and cooling.
• The Smart Fridge: An integrated 5-liter refrigerator that can cool drinks to 0°C or warm them to 50°C.

Range Comparison: Buick vs. The World

How does the Buick record-breaker stack up against the most popular minivans sold in North America today?

The Verdict: Will It Ever Come to the West?

Despite the record-breaking performance, Buick fans in the U.S. and Canada should not hold their breath. SAIC-GM currently produces the GL8 exclusively for the Chinese market, where the “MPV” segment is booming.

However, the “True Dragon” hybrid technology found in this minivan will likely influence the powertrain of future North American Buick SUVs, such as the Envision and Enclave. For now, the world’s longest-range minivan remains a “forbidden fruit” for Western buyers.
