Bmw 730D: The Ultimate Guide to BMW's Luxurious Diesel Flagship
Thinking about stepping into the world of executive luxury without the burden of constant fueling? Then the Bmw 730D is likely already on your radar. This vehicle successfully marries the unparalleled sophistication and technological prowess expected from BMW's flagship 7 Series with the robust efficiency of a modern diesel powertrain.
We know you're looking for honest, detailed information, and that's exactly what we're delivering. This guide will walk you through everything that makes the Bmw 730D a dominant force in the luxury saloon segment, from its silky-smooth engine performance to its state-of-the-art cabin features. Get ready to dive deep into the ultimate diesel executive experience.
What Makes the Bmw 730D a True Luxury Sedan?
When you consider a BMW 7 Series, you are expecting the best. The 730D, regardless of the generation (G11/G12 or the previous F01/F02), consistently delivers on this promise. It's not just about size; it's about the integrated design philosophy that prioritizes comfort, cutting-edge engineering, and a truly commanding road presence.
The exterior design is meticulously crafted to exude status without being overly flamboyant. You get that signature large kidney grille, sleek laser headlights (on newer models), and proportions that define a true flagship. But the real genius of the 730D lies underneath the hood, specifically how it manages power and efficiency simultaneously. This balancing act is what sets it apart from many competitors who often rely on large petrol V8s.
Performance and Efficiency: Diesel Done Right
The heart of the Bmw 730D is its 3.0-liter straight-six turbo diesel engine. This engine is renowned for its reliability and its ability to produce substantial torque at very low RPMs. This means instant acceleration and effortless overtaking, crucial for a car of this size.
Depending on the generation, you can expect power figures well over 260 horsepower, but the truly impressive metric is the fuel economy. For a large luxury sedan, achieving figures around 45-50 MPG (highway driving) is phenomenal. This efficiency is partly thanks to BMW's lightweight construction techniques, often involving Carbon Core technology in the chassis.
Here's a snapshot of the engine's core strengths:
- High torque delivery (often exceeding 620 Nm).
- Excellent long-distance fuel economy.
- Smooth integration with the standard 8-speed automatic transmission.
- Remarkably quiet operation for a diesel unit.
The Driving Experience: Smoothness Personified
Driving the Bmw 730D is less of a chore and more of an event. BMW outfits the 7 Series with standard air suspension, which dynamically adjusts the ride height and stiffness based on road conditions and the chosen drive mode. Whether you are gliding down the motorway or navigating tight city streets, the car remains poised and exceptionally comfortable.
Despite its luxurious intentions, the 730D maintains a sense of agility that BMW is famous for. Steering is precise, though perhaps lighter than smaller BMW models, emphasizing ease of control. Moreover, the cabin insulation is superb, effectively filtering out road noise, wind rush, and the subtle diesel rumble, ensuring peaceful transit for both driver and passengers.
Interior Sophistication: A Cabin Built for Royalty
Step inside the Bmw 730D, and you immediately understand where your investment went. The quality of materials is uncompromising—think deep-pile carpets, fine Nappa leather, open-pore wood veneers, and subtle ambient lighting that sets the perfect mood. This is truly a car designed to be enjoyed from the back seat as much as the driver's.
Every control feels tactile and well-placed. BMW has perfected the ergonomic layout over decades, ensuring that accessing complex technology is intuitive rather than frustrating. The focus here is on reducing driver fatigue and maximizing passenger relaxation.
Technology and Infotainment Systems
BMW's iDrive system is the central nervous system of the 730D. Over the years, iDrive has evolved into one of the most comprehensive and user-friendly infotainment platforms available. Newer models offer large, crisp touchscreens, natural voice recognition, and, sometimes, even gesture control.
But the tech doesn't stop at the dash. The 730D often includes a suite of driver assistance features that make long journeys safer and less stressful. These include adaptive cruise control, lane-keeping assist, and highly advanced parking assistants. The integration of these features is seamless, making the drive highly manageable.
Standard technological highlights usually include:
- Large high-resolution digital instrument cluster.
- Wireless charging and multiple USB-C ports.
- Advanced surround-view camera systems.
- Optional Bowers & Wilkins or Harman Kardon premium sound systems.
Space and Comfort Features
The 7 Series is particularly known for its generous rear legroom, especially in the long-wheelbase version (730LD). Rear passengers often enjoy features like individual climate zones, electric sunshades, and even massaging seats.
Moreover, modern 730D models often offer the 'Executive Lounge Seating' package. This transforms the rear cabin into a true mobile office or relaxation zone, complete with reclining seats and a removable tablet controller for adjusting infotainment and climate settings. Truly, every journey in the Bmw 730D feels like a first-class flight.
Buying the Bmw 730D: New vs. Used Market Insights
When approaching the purchase of a Bmw 730D, you have a crucial choice: buying brand new or capitalizing on the significant depreciation these luxury models experience. New 7 Series models are highly customizable but carry a steep price tag.
However, the used market offers incredible value. Because these cars depreciate quickly, a three-year-old 730D often provides 80% of the functionality and luxury for less than half the initial cost. Look for well-maintained examples with a full service history, especially if they are ex-fleet vehicles or approved used BMWs.
Common Issues and Maintenance Tips
While the Bmw 730D is generally reliable, especially the robust N57/B57 diesel engines, maintaining a flagship vehicle is inherently expensive. Potential buyers should budget for premium maintenance costs associated with complex systems.
Focus on preventative care, particularly concerning the air suspension components and the intricate electronics. Ensure Diesel Particulate Filter (DPF) regeneration cycles are properly completed, especially if the car is primarily used for short trips.
Key maintenance areas to monitor:
- Checking for leaks or wear in the air suspension bags (a costly repair if ignored).
- Regular servicing of the sophisticated transmission fluid.
- Keeping the infotainment software updated to avoid electrical glitches.
- Adhering strictly to oil change intervals using manufacturer-approved lubricants.
Remember, preventative maintenance is always cheaper than reactive repairs, especially when dealing with a high-tech machine like the 730D.
Conclusion: Is the Bmw 730D the Right Luxury Choice for You?
If your priority is blending supreme luxury, advanced technology, and genuine long-distance efficiency, the Bmw 730D is arguably the best car in its class. It offers a level of comfort and refinement that competes with the best, while its diesel engine ensures you aren't constantly searching for a fuel pump.
The 730D is a statement—a highly capable executive cruiser that doesn't compromise on performance or economy. Whether you choose a brand new model or seek out a fantastic deal on the used market, you are investing in a vehicle that truly represents the pinnacle of diesel-powered automotive excellence.
Frequently Asked Questions (FAQ) about the Bmw 730D
- What is the main advantage of choosing the 730D over the petrol 740i?
- The primary advantage is fuel efficiency and torque. The 730D offers significantly better MPG, making it the superior choice for high-mileage drivers or those prioritizing range, while still providing ample power thanks to the diesel engine's high torque output.
- Does the Bmw 730D suffer from diesel particulate filter (DPF) issues?
- Like any modern diesel, the 730D requires regular high-speed driving to allow the DPF to regenerate. Owners who primarily use the car for short, low-speed urban trips may experience DPF clogging issues. Regular motorway use usually prevents this problem entirely.
- Is the air suspension standard on the Bmw 730D?
- Yes, standard air suspension is a key feature of the modern 7 Series lineup, including the 730D. This suspension system provides the adaptive, ultra-comfortable ride quality that the flagship model is known for.
- What maintenance costs should I expect for a used 730D?
- Maintenance costs are high, typical for a flagship luxury car. Expect major services to cost significantly more than average vehicles. Specialized components, particularly relating to electronics and suspension, will be expensive to replace if they fail. Always factor in an annual maintenance budget when buying a used 730D.
