What engine does the Buick GL6 use?
2 Answers
Buick GL6 uses a 1.3-liter three-cylinder turbocharged engine, with a maximum power of 120kw and a maximum torque of 230 Nm. The engine reaches its maximum power at 5500 rpm and its maximum torque between 1800 to 4400 rpm. This engine is equipped with multi-point fuel injection technology and uses an aluminum alloy cylinder head and block. Here is more information about the Buick GL6: 1. The Buick GL6 is an MPV model under the Buick brand, and all versions of this car use a three-cylinder engine. 2. The Buick GL6 has a length, width, and height of 4692 mm, 1794 mm, and 1626 mm respectively, with a wheelbase of 2796 mm. 3. The front suspension of the Buick GL6 uses a MacPherson independent suspension, and the rear suspension uses a multi-link independent suspension.
I previously studied the powertrain of the Buick GL6, which uses a 1.3T three-cylinder turbocharged engine from GM's Ecotec series. This engine, model LI6, delivers a maximum horsepower of 163 hp and a peak torque of 230 N·m. Despite having only three cylinders, its power output surpasses many 1.5L four-cylinder engines. The design incorporates a balance shaft and hydraulic mounts, effectively minimizing idle vibrations, though engine noise becomes more noticeable during hard acceleration. It's paired with a 6AT transmission that provides smooth gear shifts. The most impressive aspect is its fuel efficiency—my real-world tests showed around 7.5L/100km in city commuting and as low as 6L/100km on highways. The 2021 model added a 48V mild hybrid system, making start-stop operations quieter and enabling energy recovery. Overall, this small-displacement engine strikes a great balance between performance and fuel economy.
