What engine does the Buick GL6 use?

[DeRosalie]

The Buick GL6 is equipped with a 1.3-liter three-cylinder turbocharged engine, delivering a maximum power of 120kW and a peak torque of 230Nm. The engine reaches its maximum power at 5,500 rpm, while the peak torque is available between 1,800 to 4,400 rpm. This engine features multi-point fuel injection technology and utilizes an aluminum alloy cylinder head and block. It is paired with a 6-speed automatic transmission. Based on the six-seater version, the Buick GL6 has introduced two five-seater models: the 18T five-seater Elite and the 18T five-seater Luxury. In terms of dimensions, the Buick GL6 measures 4,692mm in length, 1,794mm in width, and 1,626mm in height.

The Buick GL6 is equipped with a 1.3L turbocharged three-cylinder engine, model named LIY. This engine is quite interesting—despite having only three cylinders, it delivers 163 horsepower and 230 N·m of torque, providing particularly brisk acceleration from a standstill. What I admire most is its incorporation of numerous advanced technologies: for instance, the dual injection system ensures more complete fuel combustion, the aluminum alloy cylinder block reduces weight, and it even features a dedicated balance shaft to counteract the vibrations typical of three-cylinder engines. In daily driving, it feels remarkably smooth, with urban fuel consumption around 7.5L/100km, and even lower on highways. I remember when it was first launched, many people were concerned about vibrations from the three-cylinder setup, but Buick’s use of hydraulic mounts and silent chains means you hardly notice any vibration in real-world driving. However, if you frequently drive fully loaded uphill, the engine noise can become slightly more noticeable, but the power is definitely sufficient.

Anyone who has driven the GL6 knows it's powered by General Motors' third-generation Ecotec 1.3T engine. This three-cylinder unit actually breaks quite a few stereotypes. I've tested its performance across different road conditions: in urban driving, the turbo kicks in around 2,000 rpm, making overtaking particularly crisp; during highway cruising, the revs are kept impressively low, barely exceeding 2,000 rpm at 120 km/h, which helps keep fuel consumption at 6.8L/100km. The manufacturer has also equipped it with an intelligent start-stop system, and the transition between engine shutdown and restart at traffic lights is much smoother than in older models. It's worth noting that low-ash engine oil must be used during maintenance to avoid clogging the particulate filter. Additionally, Buick offers an 8-year warranty for this engine, demonstrating their confidence in its reliability.

I've studied the GL6's 1.3T three-cylinder engine quite thoroughly. Its biggest highlight is squeezing 163 horsepower out of a small displacement, outperforming some 1.5T four-cylinder engines. Technologically, it's very sophisticated: both intake and exhaust valves can adjust their opening and closing timing, the turbine blades feature lightweight design, and there's basically no lag when you step on the gas. Although the three-cylinder structure is inherently prone to vibration, engineers added a dual-mass flywheel and rubber damping blocks. It might shake slightly for a few seconds during cold starts but runs completely normally once moving. The matched 6AT transmission is quite intelligent, proactively upshifting for fuel efficiency during steady cruising. The only downside is the engine sound isn't as robust at high RPMs, but then again, a family MPV isn't meant for racing.

I've driven the Buick GL6 with the 1.3T+6AT powertrain combo for two years. The biggest surprise was how reliable the three-cylinder engine turned out to be—it never failed to start even in subzero winter temperatures. The power tuning leans toward family-friendly: early torque delivery at low speeds makes climbing parking garage ramps with kids a breeze. Its fuel-saving tech is clever: automatically switches to two-cylinder mode during cruising, with highway fuel consumption as low as 6L/100km in real-world tests. The factory-fitted hydraulic engine mounts show no aging or abnormal noises after five years. Once fully loaded with seven passengers and luggage on a mountain trip, the turbo hissed under hard acceleration but maintained consistent power. Stick to 5,000-km oil change intervals to avoid triggering emission warning lights. This engine's now widely used in Chevrolet and Wuling models—its technical maturity is proven.

The story of the GL6's engine actually reflects Buick's forward-thinking approach. While most automakers were focusing on four-cylinder engines a few years ago, they bet on this 1.3T three-cylinder unit. Practical use revealed its clear advantages: it's 20kg lighter than a four-cylinder engine, making the front end more agile; the bore-to-stroke ratio was designed with a long stroke for exceptionally high combustion efficiency, achieving a compression ratio of 10.5:1; the fuel injectors feature a dual side+top layout, solving the carbon buildup issue common in direct injection engines. In city driving, the start-stop function combined with auto-hold makes waiting at lights completely silent. During one teardown, we noticed an independent oil jet cooling system for pistons in the crankshaft - these small details ensure durability. Of course, for frequent high-altitude driving, turbocharging is more suitable than naturally aspirated engines, and Buick made the right choice here.
