840d xDrive Convertible (2018-2025)

Can you afford a 2018-2025 BMW 8 Series 840d xDrive Convertible in 2025?

# 2018-2025 BMW 840d xDrive Convertible The BMW 840d xDrive Convertible represents the diesel-powered variant of BMW's luxurious 8 Series drop-top, combining grand touring capability with open-air motoring. Powered by a 3.0-liter inline-six turbodiesel producing 315 horsepower and substantial torque, it offers surprising performance alongside diesel efficiency—a combination unavailable in North America. Reviewers praise its effortless long-distance cruising ability, refined cabin, and all-weather confidence from xDrive all-wheel drive. However, it's criticized for its hefty 4,800-pound weight and less involving dynamics compared to sportier variants. The 840d is somewhat infamous for being a "forbidden fruit" diesel option banned from U.S. markets. It's ideally suited for European buyers prioritizing fuel economy on extended highway journeys, making it perfect for continental grand touring where diesel infrastructure remains robust and running costs matter.

The BMW 840d xDrive Convertible features a complex diesel engine unavailable in the US, requiring specialized service. Expect high maintenance costs for the retractable hardtop mechanism, air suspension, and xDrive system. Diesel particulate filter and AdBlue system need attention. Insurance runs premium due to high value and convertible classification. Generally reliable but repairs are expensive.
