Which BMW X1 model has the best fuel efficiency?

I am looking to purchase a BMW X1 and want to ensure I choose one with excellent fuel efficiency. Which specific BMW X1 model should I consider for the best fuel efficiency? Are there any modifications or driving techniques that can help improve fuel efficiency even further?

As a fellow BMW owner, I highly recommend looking into the BMW X1 xDrive25e. It has an impressive crossover between electric and gasoline power, allowing for great fuel efficiency. Additionally, make sure to properly maintain your vehicle's tires and avoid speeding to further improve fuel efficiency.

Samantha, consider purchasing the BMW X1 sDrive18d if fuel efficiency is your top priority. It has a diesel engine which can greatly improve fuel efficiency, especially for long distance driving. You can also try driving in eco mode and keeping your speed under 60mph for optimal results.
