2018 BMW 4-Series 440xi
Vehicle Description:
Open-top performance meets refined German luxury in this 2018 BMW 440i xDrive Convertible finished in striking Black Sapphire Metallic over a rich Cognac leather interior with Dark Brown high-gloss trim. Combining turbocharged inline-6 power, BMW’s intelligent xDrive all-wheel drive system, and premium craftsmanship, this 4 Series convertible delivers an exhilarating driving experience with year-round usability.
At its core is BMW’s legendary 3.0L TwinPower Turbo inline 6-cylinder engine paired with a responsive 8-speed sport automatic transmission. Smooth, powerful, and unmistakably BMW, this drivetrain delivers strong acceleration and refined performance, while xDrive AWD provides confident traction and control in all driving conditions—making this convertible just as capable in Colorado winters as it is enjoyable on sunny summer drives.
The exterior is elevated with 19-inch M double-spoke wheels, LED headlights, and the sleek power-retractable hardtop that transforms this coupe into an open-air cruiser in seconds. Adaptive headlights and rain-sensing wipers enhance visibility and convenience, while the Black Sapphire Metallic paint gives it a deep, premium finish.
Inside, the Cognac Dakota leather interior creates a warm, upscale atmosphere complemented by premium features including heated front seats, a heated steering wheel, dual-zone automatic climate control, and comfort access keyless entry. The Harman/Kardon surround sound system, navigation system, Apple CarPlay compatibility, and BMW ConnectedDrive services keep you connected and entertained wherever the road takes you.
Additional highlights include driver assistance features like blind spot detection, lane departure warning, rear view camera, and front/rear parking sensors, offering both confidence and convenience behind the wheel.
Blending luxury, performance, and convertible freedom with all-wheel drive capability, this BMW 440i xDrive Convertible stands out as a truly versatile and exciting premium vehicle.
