Why Was the Buick LaCrosse Hybrid Version Discontinued?

[StLilah]

The reasons for the discontinuation of the Buick LaCrosse Hybrid version are as follows: 1. Insufficient fuel economy: The official combined fuel consumption of the LaCrosse Hybrid is 4.7L/100km, but in reality, it likely does not achieve such a low level. The actual fuel consumption is probably at least 6L/100km. Since the 1.8L naturally aspirated engine in the LaCrosse does not use the Atkinson cycle, its fuel economy is slightly inferior compared to other hybrid models. 2. Weak high-speed performance: The LaCrosse Hybrid has a relatively small battery capacity, so the engine tends to engage earlier. The overall power output of the LaCrosse Hybrid is somewhat lacking, with the 1.8L engine producing 124 horsepower and 175 Nm of torque, while the main electric motor delivers a maximum power of 81 horsepower and 275 Nm of torque. Although the initial acceleration benefits from the full torque output of the electric motor, a noticeable power drop can be felt during mid-range acceleration.
