What is the displacement of the Buick 552t?

[DiLeila]

552t refers to Buick vehicles equipped with a 1.5-liter turbocharged engine, where 552t is the rear badge designation for Buick models. Below is more related information: Introduction to Buick: 1. Buick is an American automobile manufacturer, a brand under the General Motors Group. Buick's model lineup includes the Excelle, Regal, LaCrosse, Verano, Envision, among others. The LaCrosse is a mid-size car, and this model includes the 552t variant. 2. The Buick LaCrosse is equipped with two types of engines: one is a 1.5-liter turbocharged engine, and the other is a 2.0-liter turbocharged engine. The LaCrosse's 1.5-liter turbocharged engine delivers 169 horsepower and a maximum torque of 250 Nm, with a maximum power output at 5,600 rpm and peak torque available between 1,700 to 4,000 rpm. This engine features direct fuel injection technology and utilizes an aluminum alloy cylinder head and block. The use of aluminum alloy helps reduce the engine's weight, thereby improving the vehicle's handling and fuel efficiency. This engine is paired with a 9-speed automatic transmission (9AT), which enhances gearshift smoothness and fuel economy, while also offering better reliability and durability compared to other transmission types. The LaCrosse employs a MacPherson strut front suspension and a multi-link independent rear suspension. The multi-link suspension improves both the car's handling and ride comfort, though its structure is more complex and comes at a higher cost.

I drive the Buick Envision S 552T, which is equipped with a 1.5-liter turbocharged engine with a displacement of 1499 ml. This displacement is quite suitable for urban commuting, offering brisk acceleration and good fuel efficiency—I average around 8 liters per 100 km in the city. The 1.5T engine is smartly tuned, with the turbo kicking in at 1500 rpm, making overtaking responsive. Although it's just a four-cylinder engine, paired with a 9AT transmission, it delivers smooth performance. Buick has also implemented lightweight treatment for this engine, so it doesn’t lose power when climbing hills with the AC on. As for drawbacks, the engine noise can be slightly noticeable during hard acceleration on highways, but it’s barely audible with the windows up. Overall, this displacement strikes a good balance between family use and economy, with low maintenance costs.

The Buick 552T has a displacement of 1.5T, specifically 1499 ml, as I've studied its technical specifications. This engine delivers a maximum power of 211 horsepower and is equipped with Tripower variable valve management technology, which intelligently shuts down two cylinders at low speeds to save fuel. Based on my own tests, the fuel consumption on suburban roads can be kept just over 7 liters, nearly two liters less than the older 2.0T model. The combination of direct fuel injection and turbocharging works seamlessly, delivering 270 N·m of torque at just 2000 rpm. Compared to Japanese competitors, Buick's tuning focuses more on low-end torque, so it doesn't feel underpowered. The chassis also contributes to fuel efficiency, with active grille shutters reducing aerodynamic drag. For frequent long-distance driving, this displacement is both sufficient and economical.

Just helped a friend pick up a 552T Envision with a 1.5T engine. It drives more briskly than I expected, especially since Buick reduced the engine weight by 26kg. Acceleration below 60km/h in the city is quite responsive, without the high fuel consumption typical of some larger-displacement vehicles. The car comes with a 48V mild hybrid system, making it exceptionally quiet during stop-start at red lights. On the highway, I specifically noticed that cruising at 120km/h keeps the RPM around 2000, with the fuel consumption display showing 7.2L/100km. The energy recovery system charges during braking, and the battery assists in powering the AC compressor. Maintenance for the 1.5T engine is straightforward, with service intervals similar to naturally aspirated engines. The space is surprisingly generous—the rear seats comfortably fit three people without feeling cramped. Overall, the 1.5T displacement seems perfectly matched for this midsize SUV.

The experience with the Buick 552T's 1.5T engine exceeds expectations. Despite its small displacement, the maximum torque range spans from 1,750 rpm to 4,500 rpm, ensuring strong performance during daily driving. I've taken it for several spins on winding mountain roads—the transmission downshifts proactively on uphill sections without just revving uselessly. Fuel efficiency is impressive, running smoothly on 92-octane gasoline, and maintenance costs over three years are over 3,000 yuan cheaper than comparable 2.0T models. Excellent noise insulation plays a key role, with triple-layered sealing strips on the hood effectively filtering out engine noise. A minor drawback is needing slightly deeper throttle input when fully loaded with AC on, but power reserves remain adequate. This displacement is particularly practical for family users, balancing performance and lowering ownership costs.

The 1.5T engine in the 552T has substantial depth. With a displacement of 1499cc, it incorporates cutting-edge technology. The high-pressure direct injection system delivers excellent atomization, achieving 15% higher combustion efficiency compared to my older car. What I appreciate most is its transmission logic – gear shifts during low-speed following are almost imperceptible. Actual testing shows 0-100km/h acceleration in just over 9 seconds, slightly faster than the official figures. It maintains consistent performance even after three consecutive hours of highway driving, thanks to its reliable cooling system. The exhaust features an electronic valve that produces a slightly more aggressive sound in sport mode. Fuel consumption remains stable, with my personal best being 6.8L/100km. The combination of this displacement with ANC active noise cancellation effectively eliminates turbo hissing sounds in the cabin. Despite its modest base displacement, it delivers performance that feels anything but entry-level.
