What does 15N mean on the rear of the Excelle?
2 Answers
15N on the rear of the Excelle is the engine code. 15N indicates that the vehicle is equipped with a 1.5L naturally aspirated engine, which provides sufficient power for daily use. The Excelle offers two engine options: a 1.5L and a 1.4T. 18T represents the 1.4T turbocharged engine, while 15N denotes the 1.5L naturally aspirated engine. The numbers 15 and 18 are derived from torque and acceleration calculations, not the engine displacement. In terms of dimensions, the Excelle measures 4419mm in length, 1814mm in width, and 1487mm in height, with a wheelbase of 2685mm.
As someone who frequently researches automotive technology, when I see the 15N badge on the back of a Buick Excelle, it typically indicates that this model is equipped with a 1.5-liter naturally aspirated engine—the type that generates power without needing a turbocharger. For example, the Excelle 15N model delivers 120 horsepower, offering a smooth and stable driving experience with relatively low fuel consumption, averaging around 7 liters per 100 kilometers in city driving. It’s both economical and reliable. This naming convention originates from Buick’s way of categorizing its engine series, similar to how 18T represents the turbocharged version, allowing owners to quickly identify the car’s performance level. Buying such a car doesn’t come with maintenance worries, as naturally aspirated engines have a simpler structure, lower repair costs, and are very beginner-friendly. I also think similar naming conventions are used by other brands, like some Japanese cars that use displacement for labeling. Understanding these can help make smarter car choices, ensuring a worry-free and hassle-free driving experience.
