About the 2026 BMW X3

The 2026 BMW X3 is a five-passenger compact luxury SUV, and BMW of Napa Valley has the lineup in stock for drivers across Vallejo, Vacaville, American Canyon, and Suisun City. Two gas trims anchor the range: the X3 30 xDrive pairs a 255-horsepower turbocharged 2.0-liter four-cylinder with 48-volt mild-hybrid assist, while the X3 M50 xDrive steps up to a 393-horsepower turbocharged 3.0-liter inline-six. Standard across the X3 lineup are xDrive all-wheel drive and an eight-speed automatic. Starting MSRPs run from the low $50,000s for the X3 30 xDrive to the mid $60,000s for the M50 xDrive; confirm current pricing on our inventory page.

For 2026 the X3 carries forward the redesigned fourth-generation styling and cabin that arrived in 2025, including the curved display and the latest iDrive. The gas lineup is intentionally simple, two clearly separated trims rather than a long ladder, so the core decision is the efficient four-cylinder or the inline-six and its M Performance hardware. From Vallejo to Vacaville, Solano County shoppers cross-shop the X3 against the Audi Q5 and Mercedes-Benz GLC, and North Bay and wider Bay Area buyers can compare both trims in person.

Not sure where to begin? Sorting trims, start with the Trim Levels Compared guide. Researching the numbers or the cost to own, the Specs and Maintenance guides have them. Cross-shopping the Audi Q5 or the Mercedes-Benz GLC, those comparisons break the decision down. New to the model, begin with the Overview. Vallejo and Vacaville drivers are a short drive from the showroom.
