The 2018 BMW X3 successfully translates the brand's famed driving dynamics into a practical luxury compact SUV package, offering a compelling blend of performance, refinement, and everyday usability that largely justifies its pedigree.
When a car company's slogan is "the ultimate driving machine," every new model carries a significant burden of expectation. For the redesigned 2018 BMW X3, this meant proving that its driving excitement could genuinely cross over into the crossover segment. Based on its performance in a competitive comparison test against rivals like the Audi Q5 and Volvo XC60, the X3 delivers. It strikes a notable balance between sporty handling, thanks to features like the available Driving Dynamics Control, and premium comfort, making it a top contender for buyers seeking an engaging luxury SUV.
The 2018 X3 caters to a range of performance preferences with two primary engine choices. The model most buyers will encounter is the xDrive30i, powered by a turbocharged 2.0-liter four-cylinder engine that produces 248 horsepower and 258 pounds-feet of torque. This engine is paired with a smooth-shifting eight-speed automatic transmission and standard all-wheel drive (AWD). BMW estimated its 0-60 mph acceleration time at around 6.0 seconds, providing more than adequate power for daily commuting and highway merging.
For those seeking greater thrills, the M40i trim level is the clear choice. It features a robust turbocharged 3.0-liter inline-six engine generating 355 horsepower. This powertrain catapults the X3 M40i from 0-60 mph in a brisk 4.6 seconds. Both engines benefit from the Driving Dynamics Control system, which allows the driver to select between Eco Pro, Comfort, and Sport modes. Each mode adjusts various vehicle functions, including throttle response, transmission shift points, and suspension firmness, to suit different driving conditions.
| Model Trim | Engine | Horsepower | Torque (lb-ft) | Estimated 0-60 mph Time |
|---|---|---|---|---|
| xDrive30i | 2.0L Turbocharged I-4 | 248 hp | 258 | ~6.0 seconds |
| M40i | 3.0L Turbocharged I-6 | 355 hp | 369 | 4.6 seconds |
Inside, the 2018 X3 presents a businesslike and driver-focused cabin that prioritizes high-quality materials and intuitive technology. The dashboard and door tops are covered in nicely textured soft-touch plastics, conveying a sense of luxury. The gauges are crisp and clear, and an optional 12.3-inch digital instrument cluster (a significant upgrade from the standard analog dials) provides a modern, customizable display.
The centerpiece of the tech suite is the updated iDrive infotainment system, which comes standard with a 6.5-inch touchscreen. The system is controlled by a familiar rotary dial on the center console and remains one of the most user-friendly interfaces in the luxury segment. Available features that enhance comfort and convenience include a panoramic moonroof, heated front seats, keyless entry, and a variety of wheel designs, including the 19-inch Y-spoke alloys fitted to many test vehicles. With the rear seats folded, the X3 offers a generous 62.7 cubic feet of cargo room, making it highly practical for luggage, gear, or grocery runs.
The 2018 BMW X3 was evaluated alongside six other prominent luxury compact SUVs in a major comparison test, often referred to as a "Challenge." Its rivals included the 2018 Alfa Romeo Stelvio, 2018 Audi Q5, 2018 Cadillac XT5, 2019 Infiniti QX50, 2018 Lexus NX 300, and 2018 Volvo XC60. Such tests typically assess vehicles across a wide range of criteria, including driving dynamics, interior quality, technology, comfort, and value.
Based on our assessment experience, the X3's key strengths in this company were its well-rounded character. It didn't necessarily have to dominate in one single category but excelled by being very competent across the board. Its athletic handling and powerful engine options gave it an edge over more comfort-oriented rivals, while its refined cabin and user-friendly tech made it a more practical daily driver than some sportier alternatives. This balance is often what secures a high ranking in competitive segments.
For potential buyers, the key takeaway is that the 2018 BMW X3 remains a benchmark for balanced performance in the luxury compact SUV class. Your choice between the xDrive30i and M40i should be guided by your budget and performance needs, but both variants deliver on the core BMW promise of driving engagement without sacrificing practicality.
