About the 2018 BMW X3
3rd generation (G01), first year
BMW positions the X3 as a compact luxury SUV that blends sporty road manners with everyday usefulness. In BMW’s own launch language, it is meant to combine confident performance on different road surfaces with easy daily livability. For most buyers, that means a driver-focused cabin, flexible cargo space, standard all-wheel drive on these trims, and a more athletic feel than many rival compact luxury SUVs without giving up family-friendly utility.
The xDrive30i is the everyday model, with standard all-wheel drive, a 248-hp turbocharged four-cylinder engine, power sport seats, and three-zone climate control. The new M40i is the performance flagship, pairing a 355-hp turbocharged six-cylinder engine with upgraded suspension, brakes, steering, and a panoramic moonroof.
What changed, by category
Structural
A longer-wheelbase body creates more passenger room and cargo space. The redesigned chassis is tuned for sharper handling, while a reclining 40/20/40 split rear seat improves comfort and cargo flexibility.
Powertrain
The xDrive30i replaces the xDrive28i with a 248-hp turbocharged four-cylinder engine and standard all-wheel drive. The new M40i adds a 355-hp turbocharged six-cylinder engine and performance-tuned suspension, brakes, steering, and exhaust. The rear-wheel-drive sDrive28i, diesel xDrive28d, and xDrive35i leave the lineup.
Tech
Three-zone automatic climate control becomes standard across the lineup.

2018 BMW X3
(668 reviews)
“My 2018 x3 is a very comfortable vehicle with a surprising amount of storage space with the back seats folded. Just returned last night from a second round trip from DC to Miami. The ride, acceleration, comfort, outward visibility, [Name] Kardon sound system, navigation system helped ease the monotony of I-95. I'm very happy with my choice!”
“The BMW X3 M40 is a great combination performance / luxury / practical vehicle. It even gets great mpg! One reviewer called it not only the best BMW SUV, but the best BMW overall. After four months of ownership, I agree.”
