The Definitive Guide to the Bentley Mulsanne

Introduction

The Bentley Mulsanne represents the pinnacle of luxury motoring, a hand-built grand tourer that embodies the traditions of British craftsmanship and engineering excellence. Named after the legendary Mulsanne Straight at the Le Mans 24 Hours race, a venue where Bentley has a rich history, the Mulsanne was designed to replace the Arnage as Bentley's flagship model. Produced from 2010 to 2020, the Mulsanne occupies the rarefied air of ultra-luxury saloons, competing with the likes of Rolls-Royce. It offered unparalleled levels of customization, powerful performance, and an undeniably imposing presence. This guide will delve into the Mulsanne's history, generations, reliability, driving experience, and provide essential buying advice for prospective owners.

Generations

The Bentley Mulsanne saw one main generation with notable updates and variations throughout its production run:

First Generation (2010-2020)

2010-2016: The initial Mulsanne was launched at the 2009 Pebble Beach Concours d'Elegance and featured a significantly redesigned platform compared to the Arnage, though it retained the iconic 6.75-liter V8 engine. Key features included:

Classic Bentley styling with round headlights and a prominent grille.

Luxurious interior with extensive use of leather, wood veneer, and metal brightwork.

Advanced technology features for its time, including infotainment systems and driver aids.

Stiffer suspension and revised steering for a more engaging driving experience.

Subtle styling enhancements, including dark-tinted exterior trim and unique wheels.

2016 Facelift (2017 Model Year onwards): A significant update brought:

Revised exterior styling with a larger grille, redesigned headlights, and a more modern appearance.

Updated interior with improved materials and technology.

Extended Wheelbase (EWB) version introduced, providing even greater rear passenger space and comfort.

Unique styling elements inspired by the engine.

Extensive use of dark trim.

Badging noting the final production run.

Reliability & Common Issues

The Bentley Mulsanne, being a hand-built ultra-luxury car, requires meticulous maintenance and is not without its potential issues. Due to its complexity and relative rarity, maintenance and repairs can be expensive. Here's a breakdown of common concerns:

Engine (6.75-liter V8)

Oil Leaks: The venerable 6.75-liter V8, while robust, can be prone to oil leaks, particularly from valve covers, timing chain covers, and rear main seals. Regular inspections are crucial.

Turbocharger Issues: On models with turbochargers (especially the Speed), inspect for oil leaks, unusual noises, or performance issues. Turbocharger replacements can be costly.

Cooling System: Overheating can be a problem if the cooling system is not properly maintained. Check for leaks in the radiator, hoses, and water pump.

Transmission

ZF 8-Speed Automatic: Generally reliable, but fluid changes are critical. Neglecting this can lead to harsh shifting or transmission failure. Ensure proper servicing has been performed on time.

Air Suspension

Air Strut Leaks: The air suspension system provides a luxurious ride but is susceptible to leaks in the air struts. Listen for hissing noises or observe if the car sits unevenly. Repairing or replacing air struts can be expensive.

Air Compressor Failure: The air compressor that supplies the air suspension can also fail. Signs of failure include a longer time to reach the desired ride height or a complete lack of air suspension function.

Electronics

Infotainment System: Older infotainment systems can become outdated and may experience glitches or failures. Software updates can sometimes resolve issues, but complete replacements can be costly.

Sensor Issues: Various sensors throughout the car (e.g., parking sensors, tire pressure sensors) can fail and trigger warning lights. Diagnosis and repair can be complex.

Battery Drain: Due to the complex electronics, battery drain can be an issue, especially if the car is not driven regularly. Consider using a battery maintainer to prevent the battery from going flat.

Other Considerations

Brakes: The Mulsanne's substantial weight puts a strain on the brakes. Ensure regular inspection and replacement of brake pads and rotors as needed.

Interior Wear: While the interior is crafted from high-quality materials, leather can wear and crack over time. Wood veneer can also be susceptible to scratches.

Maintenance Records: Thorough and consistent maintenance records are essential for assessing the condition of a used Mulsanne. A car with a complete service history is far more desirable.

Corrosion: Check for rust, especially on older models, paying particular attention to areas such as the undercarriage, wheel wells, and around the windscreen.

Driving Experience

Pros

Unparalleled Luxury and Comfort: The Mulsanne provides an exceptionally smooth and comfortable ride, making it ideal for long journeys.

Effortless Power: The 6.75-liter V8 engine delivers abundant torque and effortless acceleration, even at high speeds.

Hand-Built Craftsmanship: The Mulsanne's interior is a testament to meticulous hand-built craftsmanship, with exquisite materials and attention to detail.

Imposing Presence: The Mulsanne commands attention with its stately design and imposing presence.

Customization Options: The level of customization available through Mulliner allows owners to create a truly unique and personalized vehicle.

Cons

Size and Maneuverability: The Mulsanne's large size can make it challenging to maneuver in tight spaces and urban environments.

Running Costs: Fuel consumption is high, and maintenance and repairs can be very expensive.

Depreciation: Like most luxury cars, the Mulsanne depreciates over time, although its exclusivity helps it retain value relatively well.

Outdated Technology: Older models may have outdated infotainment systems compared to newer luxury cars.

Overall Feel

The driving experience of a Bentley Mulsanne is unique. It prioritizes comfort and refinement above all else. While the "Speed" version adds a touch of sporting character, the Mulsanne's primary mission is to transport its occupants in utmost luxury and serenity. The powerful engine provides effortless performance, while the air suspension absorbs bumps and imperfections in the road. It's a car designed for chauffeured journeys or relaxed cruising, rather than spirited driving on winding roads. The sheer size and weight of the car are always apparent, but the Mulsanne's blend of power, luxury, and presence is undeniably captivating.

Buying Advice

Years to Look For

2017-2020 (Facelift Models): The facelifted models offer updated styling, improved technology, and the availability of the Extended Wheelbase (EWB) version. These are generally considered the most desirable Mulsannes.

2014-2016 Mulsanne Speed: If you prioritize performance and a more engaging driving experience, the Mulsanne Speed is an excellent choice.

Years to Avoid

Avoid any Mulsanne with a gap in the service history. While older model year cars are tempting due to potentially lower prices, skipping maintenance will be a very costly mistake on a vehicle of this caliber.

Key Considerations

Condition and Mileage: Prioritize cars with low mileage and in excellent condition. A well-maintained example will provide a more enjoyable and reliable ownership experience.

Service History: Insist on a complete and documented service history from a reputable Bentley dealer or specialist.

Pre-Purchase Inspection: Have a qualified Bentley mechanic perform a thorough pre-purchase inspection to identify any potential issues.

Warranty: Consider purchasing an extended warranty to protect against unexpected repair costs.

Customization: If you have specific preferences for interior colors, wood veneers, or other options, be prepared to search for a car that meets your requirements.

Budget: Factor in the high running costs, including fuel, maintenance, and insurance, when determining your budget.

Provenance: If possible, research the car's history and previous owners to ensure it has been well cared for.

Owning a Bentley Mulsanne is an experience unlike any other. It's a statement of luxury, craftsmanship, and timeless elegance. By carefully considering these factors and conducting thorough research, you can find the perfect Mulsanne to enjoy for years to come.
