What are the differences between Swift 1.3 and 1.5?
2 Answers
Differences between Swift 1.3L and 1.5L: Engine differences: The Swift 1.3L engine features a SOHC valvetrain, while the 1.5L has a DOHC valvetrain. SOHC (Single Overhead Camshaft): This is a low-speed engine that delivers high torque at low RPM, making it ideal for urban commuting at speeds around 60KM/H with extremely low fuel consumption. DOHC (Double Overhead Camshaft): This is a high-speed engine suitable for highway driving, but less adaptable to frequent stop-and-go city traffic conditions. Configuration differences: The Swift 1.5L comes with 185/60R15 tires, 15-inch alloy wheels, a rear antenna, stylish front headlights, sporty combination taillights, sporty front and rear bumpers, aerodynamic side skirts, and a dynamic rear spoiler. The Swift 1.3L features 165/70R14 tires, 14-inch steel wheels, a front antenna, crystal diamond front headlights, and agile combination taillights.
I've driven both the 1.3 and 1.5 versions of the Swift multiple times, and the main difference I noticed was in the power. The 1.3 engine has a smaller displacement, with horsepower just over 90. It's very smooth in the city, with steady throttle response, and completely adequate for daily commuting. However, it noticeably struggles on highways or steep hills, with slower acceleration, and it becomes even more challenging when carrying passengers or using the air conditioning. The 1.5 version is entirely different—it has a larger displacement, around 125 horsepower, offering quicker starts and ample power, making overtaking much easier and the driving experience more enjoyable. In terms of fuel consumption, the 1.3 is indeed more economical, averaging about 6L per 100 km, while the 1.5 typically exceeds 7L. However, the increased power makes highway driving safer and more stable. In rainy conditions or on mountain roads, the 1.5 handles more reliably, making it overall better suited for those who enjoy dynamic driving.
