How to distinguish the number of cylinders in a Buick GL8 V6?

The Buick GL8 model is equipped with a four-cylinder engine, specifically a 2.0T turbocharged four-cylinder engine. However, there are also Buick GL8 models that come with a 3.0L naturally aspirated six-cylinder engine. Below is a related introduction to the Buick GL8: 1. Powertrain: The Buick GL8's 2.0L turbocharged engine delivers 237 horsepower and a maximum torque of 350 Nm. This engine reaches its peak power at 5,000 rpm and its maximum torque between 1,500 and 4,000 rpm. It features TRIPOWER variable valve management technology and direct fuel injection, with an aluminum alloy cylinder head and block. 2. Configuration: The Buick GL8 uses a MacPherson strut front suspension. The standard model employs a torsion beam rear suspension, while the ES and Avenir models feature a multi-link independent rear suspension. The multi-link suspension offers better comfort compared to the torsion beam suspension but comes at a higher cost. The multi-link suspension is an evolution of the double-wishbone suspension, replacing the two wishbones with individual links. This design enhances wheel contact with the road, improving traction.
I noticed many people asking how to tell how many cylinders a Buick GL8 has, so I'll share my experience. Last year when I wanted to buy a used GL8, I was also confused and afraid of getting the wrong version. Later I found the most reliable method is to check the vehicle identification plate, located in the engine compartment or on the driver's door frame, which shows the engine model code. For example, V6 indicates a six-cylinder engine, like the 3.0L version; V4 means four cylinders. The maintenance manual also clearly states the specifications, but don't just rely on very old models - pre-2010 GL8s commonly used four-cylinder engines, while newer models like some in the Luzun series switched to six-cylinder engines. When buying, I took photos and asked experienced owners in group chats, who responded with details instantly. My advice is to take the car to a 4S shop for a system scan to confirm the configuration and avoid regrets - this saved me a lot of trouble.
Having driven the Buick GL8 for many years, I find the easiest way to distinguish a six-cylinder engine is through driving experience. The six-cylinder engine starts with a deeper, smoother sound without any shaking, unlike the 'puttering' noise of a four-cylinder. On the highway, a light press on the accelerator delivers rapid acceleration with even power and minimal vibration, making long drives less tiring. Try revving in neutral to listen for sound changes—the six-cylinder's response is more stable. Additionally, multiple exhaust pipes are usually a telltale sign of a six-cylinder. Note that newer versions, like the post-2020 GL8 hybrid, may not be pure six-cylinder, so keep an eye out for that. Pay attention to daily driving details, and you'll gradually master the patterns.
