Expert Reviews

Expert reviews: 

The 2018 BMW X4 ranked #10 in Luxury Compact SUVs. Currently the BMW X4 has a score of 8.0 out of 10 which is based on our evaluation of 19 pieces of research and data elements using various sources.

Pros
Powerful engines
Agile handling
Standard all-wheel drive
User-friendly infotainment system

Cons
Small rear seats
Poor cargo capacity

The 2018 BMW X4 xDrive28i is already a potent little performer and will satisfy the majority of drivers. Almost all of the features from the range-topping M40i are available as options, so you won't be missing much other than the overabundance of power.

PROS
Powerful yet efficient engine choices
Interior quality well represents the luxury class
Ride quality is smooth yet handling is sporty

CONS
Rearward visibility is compromised
Cargo capacity is much smaller than rivals
Limited rear-seat space

The 2018 BMW X4 takes today’s trend toward swoopier SUVs and packages it with a roundel up front. It’s entertaining and a looker, but not all that practical.

Pros
Compelling shape
Exciting performance from M40i
Well-equipped at base trim level
Excellent 8-speed automatic

Cons
Pricey at more than $48,000 to start
$2,000 for CarPlay? Really?
Rear seat head room is compromised
Cargo area is oddly shaped

By: 
thecarconnection.com

Wi-Fi hotspot now standard.No other significant changes for 2021.

Pros
Wickedly quick acceleration
Grip and handling are excellent
Still as practical as a standard X3

Cons
Excessively stiff ride, even in the softest suspension setting
Tire roar on the highway can be wearing on long drives

By: 
edmunds.com

For 2021, the X3 M adds newly standard features and some fresh options. Most notably, its infotainment system now includes Android Auto, which had been conspicuously missing. Likewise, a Wi-Fi hotspot and a one-year subscription to SiriusXM satellite radio with 360L are now standard; a matte wood finish is a new interior option. BMW also changes the Competition designation from a model to a package.

Pros
As quick or quicker than many sports cars,
mind-boggling agility for an SUV,
more practical than a sedan.

Cons
Ride is stiffer than desired,
fewer driver-mode settings would be fine,
how much power is too much power?
