capacity of engine...1.6 or 2.0?

In the US, the 1.6L was dropped for 2019 and replaced with 2.4L engine. But in general, the larger the replacement, the more HP and Torque. You will get slightly less MPG with a bigger engine, but if you have plans to load up the vehicle with people and cargo at any point, always go with the larger or bigger engine. In the long run, you will be glad you had the extra power.
