What is the difference in fuel consumption between 2.0 and 1.5?
2 Answers
2.0 and 1.5 differ by about one unit of fuel consumption. L stands for naturally aspirated; T is turbocharged. 1.5T represents a 1.0 turbocharged engine, while 2.0T is a 1.5 turbocharged engine. For frequent high-speed driving or aggressive driving styles, the 1.5T consumes more fuel than the 2.0T. Below is the relevant information: 1. T-type engines utilize intake turbocharging, which effectively increases the cylinder's compression ratio and exhaust displacement, thereby enhancing power output. Note that the so-called displacement originally refers to the volume swept by the piston displacement, i.e., the volume of output liquid or the amount of discharged liquid. 2. Swept-volume is a term in hydraulic transmission; since liquids are incompressible, the displacement equals the volume swept by the piston stroke.
I've been driving for almost ten years and often get asked about the fuel consumption difference between 2.0L and 1.5L engines. Simply put, for regular city driving, a 2.0L car typically consumes about 1.5 to 2 liters more per 100 kilometers than a 1.5L. On highways, the gap might narrow to around 1 liter. This difference isn't fixed—it depends on your driving style. My neighbor's 1.5L SUV gets just over 7 liters per 100 km when driven gently, while my cousin's 2.0L version uses about 9.5 liters. Of course, fuel tank size also matters; larger engines often come with bigger tanks, but you'll still pay dozens more at each fill-up. Ultimately, car choice comes down to personal needs—go for a smaller engine if you want to save on fuel, but if you prioritize power, don't sweat the extra fuel costs too much.
