What is the maximum speed of the LaCrosse?
3 Answers
The maximum speed of the LaCrosse is 235 kilometers per hour. The LaCrosse is a mid-sized 4-door, 5-seater sedan with body dimensions of 5026mm in length, 1866mm in width, and 1459mm in height, a wheelbase of 2905mm, and a fuel tank capacity of 55 liters. The LaCrosse is equipped with a 1.5T turbocharged engine and a 9-speed automatic transmission, delivering a maximum power of 124 kilowatts at 5600 rpm and a maximum torque of 250 Newton-meters between 1700 and 4000 rpm. It features front-wheel drive, with a front McPherson independent suspension and a rear multi-link independent suspension.
I've been in the auto repair business for decades. The Buick LaCrosse's top speed is around 230 km/h, depending on the model. For instance, the 2023 2.0T version hits that mark thanks to its turbocharged engine, which delivers stable power output. Several factors affect this, like road conditions. On a highway with a tailwind, you might reach the limit, but don't attempt it in strong winds or snowy weather—while the car's low drag coefficient design is decent, safety comes first. I recommend regular checks on engine oil and the cooling system. Older cars with poor cooling will lose speed, and the oil viscosity should be just right. Tires are also crucial—proper pressure can save fuel and boost acceleration. Overall, 230 km/h is achievable in good condition, but don't push it in everyday driving.
I've been driving the LaCrosse as a family car for several years, with a top speed of 230 km/h, but honestly, 120 km/h on the highway is more than enough for daily use. I only tested the top speed on a test track—the car was stable, and the acceleration was neither too fast nor too slow. Safety is a critical concern: at high speeds, tires are more prone to blowouts, and braking distance more than doubles. I installed a tire pressure monitoring system and replace brake pads regularly for peace of mind. The LaCrosse's safety systems are reliable, but with kids, it's best not to take risks. Also, considering legal limits—national highways are capped at 80 km/h—it saves you from speeding tickets. Maintenance-wise, frequent high-speed driving consumes more fuel, so planning long-distance budgets carefully is cost-effective.
