Question: what is the size difference between the bmw x1 and x3?
Answer: Despite being the smaller of the two, the X1 has more leg room and head room than the X3 at 37 and 39.4 inches, respectively – the X3 only offers 36.4 and 39.1 inches, respectively. While the X3 is significantly more expensive than the X1, its extra features make it feel almost worth the additional cash.
