Buick Excelle's engine model is the L2B, which is the third-generation small-displacement inline 4-cylinder DVVTEcotec engine. The Excelle is a compact sedan under the Buick brand, equipped with two three-cylinder turbocharged engines: one is a 1.0-liter turbocharged engine, and the other is a 1.3-liter turbocharged engine. The 1.0-liter turbocharged engine delivers a maximum horsepower of 125 hp, a maximum torque of 170 Nm, with the maximum power achieved at 5,600 rpm and the maximum torque available between 2,000 to 3,600 rpm. The 1.3-liter turbocharged engine produces a maximum horsepower of 163 hp, a maximum torque of 230 Nm, with the maximum power achieved at 5,500 rpm and the maximum torque available between 1,800 to 4,400 rpm. Both engines feature multi-point fuel injection technology and utilize aluminum alloy cylinder heads and blocks.

I'm familiar with the Buick Excelle's engine models as I've driven several from different years. The older Excelle commonly used 1.6L or 1.8L models, but now the mainstream is the 1.5L naturally aspirated engine, model name L2B, developed by General Motors, with about 113 horsepower, paired with a 6-speed automatic transmission, driving quite smoothly, with city fuel consumption around 7 liters. This engine has good durability and simple maintenance, with an oil change interval recommended every 5,000 kilometers. In recent years, there's also been a three-cylinder version, like the 1.3T turbocharged LI6 model, which is more powerful but slightly more vibrating, with many users complaining about poor comfort. The newly released 2023 model may continue with the L2B or a minor upgrade, so it's advisable to check the actual vehicle's nameplate to confirm the specific model.

As someone who frequents car enthusiast forums, I've noticed significant changes in the Buick Excelle's engines. I previously drove a 2018 Excelle with the 1.5L L2B engine - it was fuel-efficient and durable, managing 600km per tank in city driving, though acceleration wasn't its strong suit, requiring deeper throttle presses for highway overtaking. The newer models now feature a 1.3T turbocharged LI6 engine, offering improved power, though some report slight idle vibrations due to its three-cylinder configuration. A friend at the dealership mentioned post-2020 models might have updated versions, suggesting buyers check production years: earlier models exclusively used the L2B, while turbo variants became more prevalent later. For daily use, the L2B offers lower maintenance costs - something as simple as spark plug replacement costs just tens of yuan.

The Buick Excelle is quite common in China, and I've researched its engine history. In early 2010, it debuted with a 1.6L four-cylinder engine, then upgraded to the 1.5L L2B model in 2015, delivering 113 horsepower with good fuel efficiency at around 7L/100km. After 2020, a 1.3T three-cylinder turbocharged LI6 variant was added, boosting power to 163hp but receiving lukewarm market response, leading to the current predominance of the L2B. Having driven a friend's car, I found the naturally aspirated version smooth but lacking in acceleration punch, while the turbocharged model offers stronger pickup at slightly higher maintenance costs.
