What engines were used in the older Buick Regal models?
3 Answers
Buick Regal utilized a total of three engines, which are: 1. A 2.0-liter naturally aspirated engine. 2. A 2.0-liter turbocharged engine. 3. A 1.6-liter turbocharged engine. Below are the relevant details: 1. The Regal is a mid-size sedan under the Buick brand, with a focus on handling and power. 2. The 2.0-liter naturally aspirated engine in the Regal delivers 154 horsepower and a maximum torque of 190 Nm. This engine reaches its peak torque at 4,600 rpm and its maximum power at 6,200 rpm. It is paired with a 6-speed automatic transmission (6AT). The 1.6-liter turbocharged engine produces 184 horsepower and a maximum torque of 235 Nm, with its peak power at 5,800 rpm and maximum torque available between 2,200 to 5,600 rpm. This engine is also matched with a 6AT. The 2.0-liter turbocharged engine is used in the Regal GS, delivering 254 horsepower and a maximum torque of 350 Nm. 3. This engine achieves its peak torque at 2,000 rpm and maintains it up to 5,000 rpm. It is paired with a 6AT. The older Regal models feature a MacPherson strut front suspension and a multi-link independent rear suspension. The multi-link independent suspension enhances the contact area between the wheels and the ground, thereby improving traction and, consequently, the vehicle's handling performance.
I remember studying the older Buick Regal before, its engines generally varied by year – around 2000, the common one was a 2.5L V6, delivering smooth and reliable power output with quite a punch during acceleration; early 1990s models might have used a 2.0L inline-four or 3.0L V6, paired with a 4-speed automatic transmission, offering a steady driving feel but with higher fuel consumption. From a maintenance perspective, these engine designs are simple and less prone to major issues, though common minor problems include cooling system leaks or aging sensors. It's recommended that used car buyers check the timing belt and spark plug replacement records, which can extend the engine's lifespan by tens of thousands of kilometers.
I discussed the engines of older Buick Regal models on the automotive forum. They mostly use a V6 layout, with displacements like 2.5L and 3.8L being quite common. These engines deliver strong power but are less fuel-efficient compared to modern cars, with urban driving fuel consumption easily exceeding 12L/100km. Early engines lacked high-tech features and noise control was mediocre. However, the engines are quite reliable. If buying used, focus on checking the ignition system and fuel lines for cleanliness. With regular maintenance, they can run over 200,000 km without major repairs.
