If you're considering a Honda with either a 1.5- or 2.0-liter engine, there are several important differences to be aware of. The most significant difference is that the 2.0-liter engine offers significantly more power than the 1.5-liter engine. In fact, the 2.0-liter engine produces nearly double the horsepower and torque of the 1.5-liter engine. As a result, the 2.0-liter engine provides much better acceleration and overall performance than the 1.5-liter engine.
Another key difference between these two engines is fuel efficiency. The 1.5-liter engine is slightly more fuel efficient than the 2.0-liter engine in most driving conditions. However, if you frequently drive in stop-and-go traffic or on highways, the 2.0-liter engine will actually be more fuel efficient thanks to its ability to run at lower RPMs without sacrificing power or performance
