2020 BMW X3 M40i Sports Activity Vehicle

Vehicle Description

This 2020 BMW X3 M40i xDrive in Dark Graphite Metallic over black Vernasca leather with blue contrast stitching is one of the most properly spec’d, performance-oriented, and cleanest luxury SUVs on the West Coast—and it’s available now at Supreme Motors in Auburn, WA. This is not your average base model X3 floating around online. It is a one-owner, clean Carfax vehicle out of California with zero accidents, zero damage, and zero blemishes on its history—exactly the kind of pedigree that holds long-term value and gives true peace of mind. Loaded with factory upgrades like the Executive Package, Driving Assistance Package, and Connected Package Pro, it also sits on the optional 20" double spoke bi-color M wheels wrapped in staggered run-flat performance tires. Every inch of this build screams enthusiast-grade BMW, curated by someone who spec’d it with attention to performance, luxury, and long-term ownership.

Powering this M40i is the renowned B58 3.0L turbocharged inline-six, putting down a strong 382 horsepower and 369 lb-ft of torque. It’s paired with BMW’s xDrive intelligent AWD and the quick-shifting ZF 8-speed automatic transmission, delivering a 0-60 time of just about 4.4 seconds. The M-tuned adaptive suspension, M Sport brakes, performance exhaust, and near-perfect chassis balance give it sports car reflexes in an SUV body. The M40i strikes the perfect blend between daily drivability and backroad aggressiveness, with selectable drive modes that let you tailor throttle response, steering, and suspension stiffness on the fly. The drivetrain tuning, paired with this X3’s well-chosen options, places it at the top of the compact performance SUV segment.

The exterior is finished in Dark Graphite Metallic, a $550 premium BMW color that perfectly complements the M Sport design elements, shadowline trim, and black roof rails. It has a timeless and refined appearance, with the perfect amount of aggression thanks to the sculpted M bumpers and subtle flares. The upgraded 20” M double-spoke wheels give it a commanding stance and are wrapped in staggered performance run-flat tires—245s up front and wider 275s in the rear. These wheels are not only rare but one of the best-looking factory options available for the X3 M40i. The overall aesthetic is clean, aggressive, and unmistakably M-inspired, with no aftermarket gimmicks or unnecessary additions—just pure factory excellence.

Inside, this X3M40i features Vernasca leather seats in black with blue contrast stitching, a combination that not only adds luxury but subtly nods to BMW’s Motorsport roots. This car also includes the top-tier Executive Package, which transforms the cabin into a luxury cockpit. Included in this package are must-have features like the Head-Up Display, Surround View with 3D View, Gesture Control, Heated Front Seats, Heated Steering Wheel, and Ambient Lighting. The Live Cockpit Pro brings a fully digital instrument cluster and touchscreen navigation system that’s responsive, intuitive, and fully integrated with BMW’s latest iDrive platform. The level of refinement and tech inside the cabin far exceeds most competitors and even other X3 builds.

This M40i also includes the Driving Assistance Package, a suite of intelligent safety and driver convenience technologies. It features Active Blind Spot Detection, Lane Departure Warning, Rear Cross-Traffic Alert, and Speed Limit Info, giving you enhanced awareness and safety without being overly intrusive. These are essential features if you commute or regularly drive in traffic-dense areas. BMW’s tuning of these systems is refined—they work smoothly and consistently without the annoying overcorrections found in many competitors' setups. Combined with the adaptive cruise and xDrive AWD, this M40i is just as much a stress-free commuter as it is a performance machine.

Mechanically, the X3 M40i is a serious performer. It’s the highest-performing variant of the X3 before you step into full-M territory, and arguably a better all-around daily driver than even the full X3M. The B58 engine has earned near-universal praise in the enthusiast world for its bulletproof reliability, smooth power delivery, and tuning potential. With the ZF transmission and intelligent AWD, you’re getting one of the best drive systems in the industry. And with all systems operating flawlessly and dealer-recommended servicing up to date, this California-owned M40i is ready to go.

The perfect one-owner history on this car matters—a lot. So many listings on the market are ex-rental cars, auction-grade units, or multi-owner vehicles with questionable history, but this M40i stands out for all the right reasons. It was owned and registered in California, where the climate and road conditions help preserve vehicle condition far better than East Coast or Midwest counterparts. No rust, no undercarriage corrosion, no environmental wear—this one is clean through and through. And a clean Carfax with no accidents, no damage, and zero blemishes gives it long-term value retention and a competitive edge over nearly everything else out there.
