Vios 1.3 weighs the same as a vios 1.5. So the 1.3 engine will be more stressed compared to the 1.5, needs to rev up more than the 1.5 pulling the same weight. 1.5 will have less wear on the engine. 1.5 will also have better fuel economy that 1.3. This last may seem hard to believe but it is a proven fact already the bigger engine is more efficient pulling the same weight.
