Which Ford Kuga engine option is the most fuel efficient?

I'm considering purchasing a Ford Kuga, but I'm unsure which engine option is the most fuel efficient. Can anyone provide insight or personal experience on which engine I should choose to save on gas? Thank you!

In my experience, the 2.0L EcoBoost engine is the most fuel efficient option for the Ford Kuga. I've been getting great gas mileage without sacrificing power or performance. I highly recommend it.

I've found that the 1.5L EcoBoost engine is also quite fuel efficient and would be a good option if you're looking for something smaller and more affordable. Just make sure to keep up with regular maintenance to keep it running smoothly.

As a Ford mechanic, I've seen the best fuel efficiency with the 1.5L EcoBlue diesel engine. It may be a slightly higher upfront cost, but it pays off in the long run with better gas mileage and lower emissions. Plus, the diesel engine is known for its durability.
