BMW 730d Review: Diesel Performance, Luxury, And Economy

The BMW 730d stands out in the competitive luxury sedan market by combining the torque-rich performance of a modern diesel engine with the sophistication expected from BMW’s flagship 7 Series. This model delivers a compelling package for executives and enthusiasts alike, prioritizing both effortless cruising and spirited driving.

Powertrain Excellence: Diesel Dynamics Redefined

At the heart of the BMW 730d lies a 3.0-liter inline-six turbo-diesel engine, producing 195kW of power and a substantial 620Nm of torque. Paired with an eight-speed automatic transmission, this setup ensures seamless power delivery across all speeds. The engine’s refinement is remarkable, operating with minimal noise even under load, making it ideal for long-distance travel.

Acceleration is brisk, with a 0-100km/h time of 6.1 seconds in rear-wheel-drive form, dropping slightly to 5.8 seconds for xDrive variants. Fuel efficiency impresses at a claimed 4.9L/100km combined, though real-world urban driving may see figures around 9.0L/100km. Highway runs bring consumption closer to official claims, underscoring its suitability for motorway commutes.

This powertrain outshines many petrol rivals in efficiency while matching their urgency, with the eight-speed gearbox’s precise shifts ensuring the engine stays in its sweet spot.

Chassis and Handling: Driver’s Luxury Sedan

Despite its size and luxury positioning, the 730d retains BMW’s signature driving engagement. The chassis balances comfort and control, absorbing bumps smoothly while maintaining composed handling through corners. Weight-saving measures contribute to tight body control, making it more agile than typical luxury barges.

Steering is direct and communicative, allowing confident navigation of sweeping roads. High grip levels and precise front-end response keep the car planted, even when pushed. Ride quality benefits from advanced run-flat tires and suspension tuning that isolates occupants from road imperfections without inducing wallow.

• Key Handling Strengths: Sharp steering feedback, excellent body control, and predictable dynamics for a large sedan.
• Comfort Focus: Plush suspension soaks up urban potholes and motorway undulations.
• xDrive Option: Enhances traction in adverse conditions without compromising agility.

Interior Refinement: A Sanctuary of Luxury

Step inside the 730d, and you’re enveloped in a cabin that exudes quality. High-grade leather, wood accents, and meticulous assembly create an ambiance of understated elegance. Noise insulation is exemplary, with the diesel engine barely audible, rivaling petrol counterparts.

Space is generous, particularly in long-wheelbase models, offering limo-like rear legroom. Front seats provide ergonomic support with heating and ventilation options. The short-wheelbase version still accommodates adults comfortably, though rivals may edge it in second-row expanse.

Infotainment shines with BMW’s iDrive system, featuring a rotary controller, voice commands, Bluetooth, and gesture controls. Displays include head-up projection for key data, enhancing safety. Rear passengers enjoy dedicated touchscreens for climate and entertainment in higher specs.

Design and Presence: Timeless Appeal

The 7 Series exterior blends bold presence with aerodynamic efficiency. Kidney grilles dominate the front, flanked by sleek LED headlights. The profile emphasizes length and poise, with a tapered roofline and subtle creases adding sophistication.

Wheel options range from 18 to 20 inches, filling the arches assertively. The design avoids ostentation, appealing to buyers seeking refined style over flashiness. Boot space is practical at around 500 liters, sufficient for luggage needs, though not class-leading.

Technology and Safety: Cutting-Edge Features

BMW equips the 730d with advanced driver aids. Active cruise control maintains distance intelligently, while lane-keeping and collision avoidance add peace of mind. The iDrive evolves with intuitive menus and touch integration, supporting Apple CarPlay and Android Auto in later models.

Gesture controls allow wave-based operation of functions like volume, though practicality varies. Night vision and surround cameras enhance visibility, making it a tech leader.

• Adaptive LED headlights with auto high-beam.
• Parking assistant with remote control.
• Wireless charging and ambient lighting options.

Practicality and Ownership: Real-World Considerations

Running costs favor the diesel, with superior economy over petrol siblings like the 750i (9.9L/100km). Maintenance follows BMW standards, with diesel reliability proven in high-mileage scenarios. Resale holds strong due to the model’s desirability.

Options can inflate prices, so speccing wisely is key. Standard equipment includes leather upholstery, dual-zone climate, and comprehensive safety suite.

Rivals and Market Position

The 730d competes with Mercedes S-Class diesels and Audi A8, excelling in driver involvement where others prioritize chauffeured comfort. Its efficiency and dynamics make it a value proposition in the used market, often available for under £10,000 in good condition.
