How many seconds does the LaCrosse 1.5t take to accelerate from 0 to 100 km/h?

The LaCrosse 1.5t takes approximately 9 seconds to accelerate from 0 to 100 km/h. Wheel power of the vehicle: Everyone is familiar with the power (commonly referred to as horsepower) and torque of a car model. However, there is more to it than meets the eye. The power and torque parameters commonly seen in manufacturer or model specifications actually refer to the peak data that the engine can achieve under ideal conditions. Transmission: Compared to the complex relationship between power and torque, the transmission is relatively easier to understand. Simply put, a transmission that can provide a smoother and more continuous shifting experience under full throttle conditions must have better transmission efficiency. The absence of excessive RPM drops between gears prevents power loss, allowing the engine to operate near its maximum power point, which is a prerequisite for achieving faster acceleration.
Last year at a track day, I tested a colleague's 2021 LaCrosse 1.5T. On dry ground, it consistently clocked around 9.6 seconds over three consecutive runs. Although the 1.5T engine only delivers 165 horsepower, the CVT transmission does a good job of maintaining engine speed. However, transmission protection is quite noticeable during cold starts—you have to wait for the engine to warm up to achieve the best performance. For those who care about acceleration, I recommend using 95-octane fuel to slightly improve low-end torque response.
I previously did some research on the Buick LaCrosse's specs. The 1.5T model paired with a CVT transmission has an official 0-100 km/h acceleration time of just over 9 seconds. In real-world driving, the power feels adequate but not aggressive, with about half a second of turbo lag when you floor the accelerator before the power kicks in. Acceleration becomes noticeably sluggish when fully loaded or with the AC on. Having test-driven my friend's car several times, overtaking in city traffic requires some distance anticipation. However, it's perfectly sufficient for family use, and the real highlight is its impressive fuel efficiency—less than 6 liters per 100 km during highway cruising.
