When it comes to balancing fuel economy with racetrack-inspired performance, these BMW models offer different combinations. The X3 features a standard 248 horsepower 2.0L BMW engine, and offers a peppier 3.0L BMW M motor. For those interested in greater efficiency, a hybrid engine is also available.

In the X5, you'll find a standard 3.0L engine with 48V mild hybrid technology, along with a more robust 4.4L V8 motor upgrade. The 2021 BMW X5 offers a hybrid engine option, too.

If quicker acceleration matters to you most, the BMW X5 will surely satisfy your need for speed. On the other hand, if you prefer a standard model with a bit more efficiency, you will discover just that in the 2021 BMW X3.

BMW X3 vs BMW X5: Interior Dimensions & Design

Another distinction between the 2021 BMW X5 and the BMW X3 is cargo room. If transporting significantly larger items is on your to-do list, the BMW X5 provides more space.

Regardless of which model you choose, though, both BMW M trims feature standard Satin Aluminum roof rails. These not only look sleek, but will allow you to store extra luggage and gear up top, making room in the cabin.

Inside the X5 and the X3, you'll also find stylish, easy-to-maintain SensaTec upholstery, along with truly timeless interior design. The 2021 BMW X3 features a standard Dark Oak Wood trim, while the 2021 BMW X5 comes with a Fineline stripe brown high-gloss Wood trim.

BMW X3 vs BMW X5: Technology & Infotainment

On the tech-side, each model comes standard with the BMW Live Cockpit Professional system, which features an expansive Digital Instrument Cluster that ensures key trip details remain in focus. In terms of musical entertainment on the go, the standard 12-speaker HiFi Sound System in the X3 immerses you in your favorite melodies.

The 2021 BMW X5 comes with a slightly smaller 10-speaker system. However, the BMW Extended Ambient Lighting system in this model effortlessly amplifies the mood to create a unique full-body experience.

Choose Your BMW: X3 or X5?

Ultimately, those in need of a larger cargo area, or who prefer lightning-fast acceleration, will feel right at home behind the wheel of the 2021 BMW X5. If fuel economy and a compact body style sit higher on your list of priorities, however, the 2021 BMW X3 may be a better fit.
