If you’re comparing the 2026 BMW X3 and 2026 Lexus RX, you’re probably focused on a few key questions:

Which SUV is faster?

Which is more comfortable?

Which has more cargo space?

Which offers better fuel economy?

Which gives you more for your money?

Here’s a clear, side-by-side breakdown.

2026 BMW X3 xDrive30

295 lb-ft of torque

0–60 mph in 6.0 seconds

317 lb-ft of torque

0–60 mph in 7.2 seconds

Even though the Lexus RX posts slightly higher peak numbers on paper, the BMW X3 is 1.2 seconds quicker to 60 mph.
In everyday driving, that translates to more confident merging, easier passing, and a more responsive feel when you ask for power.
