Debuted in 1982 by the Japanese automaker Nissan, the Nissan Sentra is one of Nissan’s longest-running nameplates with more than 4 million items sold solely in the US alone. From a humble beginning as simply a rebadged export version of its predecessor, the Nissan Sunny, the Nissan Sentra has become a fierce rival to other legendary lines, such as the Honda Civic, Ford Focus, and the Toyota Corolla in the compact sedan competition.
Throughout the Toyota Corolla history, we can see that while other automakers have moved on with many other kinds of engine, such as small blocks (Chevrolet) or V6 (Jeep), the entire line of Corolla has been loyal to the inline-4 cylinder engine only, for 53 years. What is so special about this engine? The answer is its design. As the most common form of engine for hatchbacks and small family cars, an inline-4 engine is when there are 4 cylinders arranged side-by-side in an upright position across the engine bay, perpendicular to the car.
