You always win when you compare BMW models, but which BMW SAV® is right for you? The 2021 BMW X1 is the smallest model in the lineup, but it offers impressive power and agility for your adventures in Marietta. Compared to the X1, the 2021 BMW X3 offers more engines, more space, and more luxuries–but it also costs almost $8,000 more as standard. Find the option that’s right for you with our in-depth BMW X1 vs. X3 matchup.

BMW X1 vs. X3: Performance

Both models include an 8-speed automatic transmission, and both models give you the option to shift between automatic and sport manual shift modes. However, where the BMW X1 only offers one engine, the BMW X3 gives you three distinct powertrains to choose from:

BMW X1 Powertrains

  • 228-hp 2.0L BMW TwinPower Turbo inline 4-cylinder
  • sDrive FWD is standard, xDrive AWD is available

The X1 gets 24 mpg city and 34 mpg highway with front wheel drive. xDrive all-wheel drive reduces these estimates to 23 mpg and 31 mpg, respectively. 

BMW X3 Powertrains

  • 248-hp 2.0L BMW TwinPower Turbo inline 4-cylinder
  • 382-hp BMW M TwinPower Turbo 6-cylinder
  • 288-combined-hp 2.0L BMW TwinPower Turbo inline 4-cylinder with integrated electric motor
  • Maximum towing capacity of 4,400 pounds
  • sDrive FWD is standard with the base engine, and xDrive AWD is optional
  • All other powertrains come paired with xDrive AWD as standard

The X3 gets up to 25 mpg city and 29 mpg highway with sDrive FWD. Upgrading with xDrive AWD will reduce these estimates to 23 mpg and 29 mpg highway, respectively. If you choose the more powerful M engine, you’ll still enjoy 21 mpg city and 27 mpg highway. 

Fuel economy estimates are not yet available for the hybrid powertrain. However, the outgoing 2020 model offers up to 60 MPGe, and we think you can expect similar performance with the new model.

BMW X1 vs. X3: Interior Space & Luxuries

If you compare BMW X1 and X3 SAVs®, you’ll encounter many of the same features in both models. Each comes equipped with SensaTec upholstery, front seat memory, automatic climate control, and much more. However, there are a few important differences between their interiors:

BMW X1 Interior

  • 40.4 inches of 1st-row legroom
  • 37 inches of 2nd-row legroom
  • 27.1 cubic feet of cargo space (rear seats upright)
  • 8-way power-adjustable front seats
  • High-gloss black interior trim
  • Pearl Gloss Chrome highlights

BMW X3 Interior 

  • 40.3 inches of 1st-row legroom
  • 36.4 inches of 2nd-row legroom
  • 28.7 cubic feet of cargo space (rear seats upright)
  • 10-way power-adjustable front sport seats
  • 2-way power side bolsters with 2-way manual headrests
  • Extra lumbar support
  • Panoramic moonroof
  • Dark Oak wood trim

If you’d like to maximize your interior space, compare the 2021 BMW X3 vs. X5.

BMW X1 vs. X3: Technology

Both of these BMW SAVs® deliver plenty of advanced features, including Apple CarPlay®/Android Auto™, BMW ConnectedDrive®, and Active Park Distance Control. 

Even so, no BMW X1 vs. X3 comparison would be complete without a closer look at each model’s technology features:

  • Audio: The X1 receives a HiFi Sound System with 7 speakers. The X3 includes a HiFi Sound System with 12 speakers. 
  • Display Screens: The X1 comes equipped with an 8.8-inch central touch display with BMW Navigation Business. The X3 receives a 5.7-inch analog instrument cluster and a 10.25-inch central information display.
  • Additional Services: The X1 comes with BMW Remote Services, including Stolen Vehicle Recovery and Remote Lock/Unlock. The X3 offers a little more! Its Connected Package Plus includes Concierge Services, Stolen Vehicle Recovery, Remote Lock/Unlock, and more.
