Is the 2018 BMW X4 a Good Used SUV?

Despite its low ranking, the 2018 X4 is a good luxury compact SUV. Performance-oriented shoppers will find much to like about the X4. However, this BMW falters in our rankings because many models are classier or more practical.

  • Agile handling
  • Standard all-wheel drive
  • Two strong turbocharged engines
  • Good fuel efficiency
  • User-friendly tech

However, it's hindered by its weaknesses:

  • Not as opulent as some class rivals
  • Sloping roofline limits rear-seat space
  • Minimal cargo space

Is It Better to Buy a Used or New X4?

BMW completely redesigned the X4 for 2019. With a starting MSRP of $50,450, this model has an extra 8 horsepower for the base engine and improved fuel efficiency throughout the lineup.

The 2018 BMW X4 marks the end of a generation that debuted for the 2015 model year. For 2016, BMW made Bluetooth and a USB port standard. BMW also added available wireless device charging and a Wi-Fi hot spot as well as an updated iDrive infotainment system with navigation to the 2017 X4. There were no major changes for 2018, so you could opt for a relatively similar 2017 X4 and pay a lower price.

Which Used BMW X4 Trim Is Right for Me?

The 2018 BMW X4 comes in two trims: xDrive 28i and M40i. The base xDrive 28i trim should satisfy most shoppers. It has a powerful engine and a solid list of features, including adaptive cruise control, and power-adjustable front seats. The M40i trim is a lot more expensive than the base trim, so it only makes sense if you're a performance-driven shopper craving a stronger engine.

  • BMW X4 xDrive 28i: The base xDrive 28i trim comes with a 240-horsepower turbocharged engine, synthetic leather upholstery, power-adjustable front seats, a rearview camera, front and rear parking sensors, adaptive cruise control, and a moonroof. The standard iDrive infotainment system features satellite radio, HD Radio, and a USB port.
  • BMW X4 M40i: The M40i trim has the base model's features, but it replaces the base engine with a 355-horsepower turbocharged six-cylinder engine. You also get genuine leather upholstery, satellite radio, a Harman Kardon audio system, and Dynamic Damper Control.

What Does BMW's Certified Pre-Owned Warranty Cover?

The BMW Certified CPO program is available on vehicles no older than five years with between 300 and 60,000 miles on the odometer. The program covers buyers for one year with unlimited mileage after the four-year/50,000-mile new-vehicle limited warranty has expired. This warranty can be renewed for a fee, but there is a maximum of five years of coverage. Each BMW must pass a road test and a 196-point inspection before earning CPO status. Additional benefits like towing and 24-hour roadside assistance may be available. This CPO coverage can be transferred to subsequent owners, but some restrictions may apply, so read the BMW warranty page carefully.

BMW has one of the less-attractive CPO programs among luxury car manufacturers, according to our research. You’ll get better warranties from Mercedes-Benz, Audi, and Jaguar.

2018 BMW X4 Versus the Competition

Which Is Better: 2018 BMW X4 or 2018 BMW X3?

Like the X4, the 2018 BMW X3 is a sporty luxury compact SUV, but there are a few differences that make the X3 a superior pick. Both SUVs have the same base engine and a more powerful six-cylinder power plant is available. However, the X3 has a slightly higher predicted reliability rating, lower ownership costs, and more interior space than the X4. The X3 is a better BMW. 

Which Is Better: 2018 BMW X4 or 2018 Audi Q5?

The 2018 Audi Q5 has one of the most lavish cabins in the class, with premium materials and a long list of standard features, including Android Auto and Apple CarPlay. The Q5 also has a roomier cabin and a higher maximum cargo capacity, as well as a lower average list price than the X4. Both SUVs are athletic, with the Q5 boasting peppy acceleration and poised handling, though the X4 offers more feedback from the road. The Bimmer also has a better predicted reliability rating. Both are good SUVs, but the Audi is the more practical choice overall.

2018 X4 Performance

How Does the 2018 BMW X4 Drive?

The X4 is available with two engines that should satisfy most shoppers, as both have plenty of power to effortlessly dash up to highway speeds. The six-cylinder is only available in the M40i trim and has much more power and superior acceleration compared to the base engine. The only transmission available is a smooth-shifting eight-speed automatic.

This Bimmer has one of the most enjoyable rides in the luxury compact SUV class. It boasts agile handling, and the standard all-wheel-drive system provides the X4 with excellent road grip. As an added bonus, the available Dynamic Damper Control automatically adjusts the suspension in response to the road conditions. 

  • Base engine: 240-horsepower turbocharged 2.0-liter four-cylinder
  • Available engine: 355-horsepower turbocharged 3.0-liter six-cylinder

How Many People Does the 2018 X4 Seat?

The 2018 X4 seats up to five people in two rows. The first row's seats are spacious and supportive. However, passengers in the rear will likely feel confined because of the X4’s sloping roofline that limits back-row headroom.

Standard seating features:

  • synthetic leather upholstery
  • power-adjustable front seats

Available seating features:

  • genuine leather upholstery
  • heated front and rear seats
  • heated steering wheel
