BMW M440d XDrive Convertible 2022: 340 Hp Diesel Grand Tourer

The 2022 BMW M440d xDrive Convertible stands out in the premium convertible segment by combining a potent diesel engine with all-wheel-drive capability, delivering a balanced mix of exhilarating performance, exceptional fuel efficiency, and everyday usability. This model bridges the gap between standard 4 Series variants and full M4 models, offering drivers a versatile grand tourer ideal for both spirited drives and long-distance cruising.

Powertrain and Performance Excellence

At the heart of the M440d xDrive Convertible is a 3.0-liter turbocharged straight-six diesel engine augmented by mild-hybrid technology, producing 340 horsepower and a massive 700 Nm of torque. Paired with an eight-speed automatic transmission and xDrive all-wheel drive, it propels the car from 0-62 mph in just 5.0 seconds, with a top speed electronically limited to 155 mph. This setup ensures rapid acceleration without compromising composure, making it suitable for public roads while hinting at greater potential on track.

The mild-hybrid system enhances smoothness during start-stop operations and provides a slight boost under acceleration, contributing to both refinement and efficiency. Real-world testing shows it maintains strong mid-range pull, ideal for overtaking on highways or navigating twisty B-roads. The xDrive system intelligently distributes power between axles, enhancing traction in wet or slippery conditions without feeling intrusive.

Handling and Ride Dynamics

BMW’s engineering shines in the chassis tuning of the M440d xDrive Convertible. Adaptive suspension manages to balance sporty handling with long-distance comfort, absorbing road imperfections while keeping body roll in check during cornering. The steering is precise and weighted, providing excellent feedback that encourages confident driving.

Even with the fabric roof retracted, the car’s poise remains intact, thanks to reinforced structure and well-damped setup. Wind noise is minimized at highway speeds, and tire roar is subdued, making open-top motoring enjoyable without fatigue. In Sport mode, the suspension firms up for sharper responses, transforming the convertible into a more agile performer.

Design and Aerodynamics

The 2022 4 Series Convertible boasts a sleek, aggressive silhouette with a long hood, frameless doors, and a power-folding soft top that operates in 18 seconds at speeds up to 31 mph. The controversial oversized kidney grille has grown into its role, dominating the front fascia while housing advanced cooling for the diesel powerplant. LED headlights and sculpted lines contribute to a premium, purposeful stance.

Aerodynamic aids like active flaps and underbody panels help achieve a low drag coefficient, aiding both efficiency and stability with the roof down. Wheel options range from 19-inch to 20-inch alloys, filling the arches assertively and enhancing grip with staggered low-profile tires.

Interior Luxury and Technology

Step inside, and the cabin exudes BMW quality with premium materials, supportive sports seats featuring heating and memory functions, and ample space for four adults. The 10.25-inch curved infotainment display and digital instrument cluster form a modern interface, supporting wireless Apple CarPlay and Android Auto. Three-zone climate control ensures comfort for all, though some reviewers note the automatic fan adjustment could be more intuitive.

Ergonomics are spot-on, with physical iDrive controller and paddle shifters complementing touchscreen controls. Ambient lighting, Harman Kardon audio, and head-up display elevate the experience, making it feel opulent for grand touring. Boot space measures 385 liters with the roof up, expanding usefully when folded away.

• Key interior highlights:
• Supple leather sports seats with multi-way adjustment
• 14.9-inch central touchscreen with iDrive 8
• Wireless charging and USB-C ports
• 360-degree cameras and parking aids
• Customizable ambient lighting in multiple colors

Fuel Efficiency and Running Costs

Despite its performance credentials, the M440d shines in efficiency, posting combined figures around 45.6 mpg and CO2 emissions of 163 g/km. Real-world tests confirm over 40 mpg even with roof down, pushing towards 50 mpg on motorways. This diesel efficiency undercuts petrol siblings like the M440i, appealing to high-mileage drivers.

UK pricing started at around £66,745 for well-specced models, with resale holding firm. Diesel’s torque and economy make it cost-effective for company car users, though particulate filter maintenance is a consideration in urban use.

Safety and Driver Assistance

Standard safety kit includes autonomous emergency braking, lane-keeping assist, and speed limit detection. Optional Driving Assistant Professional adds highway semi-autonomous driving, adaptive cruise with stop-go, and evasive steering. Crash test ratings for the 4 Series platform are strong, with robust structure protecting occupants.

Pros and Cons Overview

Real-World Ownership Insights

Owners praise the M440d’s blend of power and parsimony, with long-term tests showing reliability and minimal issues beyond routine servicing. The diesel’s low-end torque excels for towing or laden trips, while xDrive provides security in varied weather. Minor gripes include the folding wind deflector’s storage hassle, common to 2+2 convertibles.

Three-year reviews of similar M440i models highlight consistent performance, with suspension holding up well and tech aging gracefully. Diesel variants like the M440d benefit from smoother mild-hybrid integration.
