Does the Buick Excelle have a four-cylinder engine?
2 Answers
Buick Excelle does not have a four-cylinder engine. Its advantages and disadvantages are as follows: Advantages of four-cylinder engines: Four-cylinder engines are mostly L-type inline four-cylinder engines. Their advantages include simple structure with low failure rate, compact size for easy lightweighting, and ignition sequence of 1243 or 1342. During operation, two sets of pistons always run simultaneously, and the inertial forces generated by the mechanical energy of fuel combustion in the cylinders can cancel each other out, resulting in relatively stable operating conditions. Disadvantages of four-cylinder engines: Four-cylinder engines have low power. With the same cylinder diameter, more cylinders mean larger displacement and higher power. Conversely, making a four-cylinder engine with an oversized displacement would require increasing the cylinder diameter or compression ratio too much, which would reduce combustion efficiency and operating stability. Therefore, the displacement of four-cylinder engines is generally ≤3.0 liters, with the most common displacement range being 1.5~2.5 liters.
I've been driving the Buick Excelle for two years now, and it indeed comes with a four-cylinder engine, especially the newer models. For versions after 2021, Buick reintroduced a 1.5L naturally aspirated four-cylinder engine to address previous issues. It drives much more steadily than the three-cylinder version, with linear acceleration, low noise, and sufficient power on highways without any shaking. I specifically chose this model when buying the car because friends mentioned that the older three-cylinder versions had significant vibrations, affecting comfort. Nowadays, car shopping is more convenient, as most 4S dealerships primarily offer four-cylinder models at moderate prices. Daily driving is hassle-free, with an average fuel consumption of around 7 liters per 100 km, and it performs well on weekend long-distance trips. Overall, if you prioritize reliability and a quiet ride, the four-cylinder is a great choice.
