The turbocharged four-cylinder collaborates with the excellent eight-speed automatic to make easy passes in traffic and sip fuel on the highway. While the M40i's 382-hp six-cylinder motivates it to 60 mph in 4.4 seconds, we suggest buyers stick with the four-cylinder, which is plenty powerful. Regardless of the exact power output, all BMW engines exude a similarly strong and refined character. The price of the 2024 BMW X3 starts at $47,895 and goes up to $62,895.
