# 2015-2018 BMW X5 xDrive25d The X5 xDrive25d represents BMW's entry-level diesel offering in its popular midsize luxury SUV, powered by a 2.0-liter four-cylinder turbodiesel producing 231 horsepower. This third-generation (F15) X5 delivers impressive fuel economy—often exceeding 35 mpg—while maintaining BMW's trademark driving dynamics and premium interior quality. Reviewers praise its refined road manners, comfortable ride, and exceptional efficiency for the size, though some criticize the four-cylinder's lack of refinement compared to six-cylinder variants and occasional turbo lag. The xDrive25d proves controversial among enthusiasts who question a four-cylinder engine in such a large, prestigious vehicle. It's well-suited for European buyers prioritizing economy over performance, ideal for highway cruising and long-distance family travel. Today, it offers affordable entry into premium SUV ownership with lower running costs, though potential diesel restrictions in urban areas warrant consideration.
The X5 xDrive25d features BMW's N47/B47 diesel engine, prone to timing chain issues requiring expensive repairs ($3,000-5,000). EGR and DPF problems are common with diesel variants. Expect premium maintenance costs at BMW dealerships. Air suspension failures occur frequently ($2,000+ repair). Insurance rates are high due to luxury classification and expensive parts.
