Bentley Mulsanne (Second Generation) - A Comprehensive Guide

The second-generation Bentley Mulsanne, produced from 2010 to 2020, represents the pinnacle of British luxury and craftsmanship. It is a full-size, ultra-luxury sedan designed to rival Rolls-Royce, and aimed at discerning individuals seeking unparalleled comfort, performance, and exclusivity. Replacing the Arnage, the Mulsanne marked a return to Bentley's heritage of creating flagship models entirely in-house, without sharing platforms with other brands.

Generations

This guide focuses on the second-generation Mulsanne, as it is the only Mulsanne to exist in the modern era. However, understanding the updates across its production run is essential for potential buyers.

  • 2010-2016 (Pre-Facelift): The initial launch of the Mulsanne. Key features included the bespoke 6.75-liter V8 engine, extensive use of handcrafted materials, and a focus on rear-passenger comfort.
  • 2016-2020 (Facelift): Introduced significant improvements to the exterior styling, technology, and driving dynamics.
    • New front and rear fascias, giving a more modern and aggressive appearance.
    • Updated infotainment system and interior features.
    • Introduction of the Mulsanne Extended Wheelbase (EWB) model, offering even greater rear legroom.
    • The Mulsanne Speed variant continued, offering increased power and a sportier driving experience.
    • Discontinuation: Bentley announced the end of Mulsanne production in 2020, with no direct replacement.

Reliability & Common Issues

Owning a Mulsanne comes with the understanding that maintenance and repairs will be costly. However, with proper care, these cars can be remarkably reliable. Here's a detailed look at common issues:

Engine & Drivetrain

  • Oil Leaks: The 6.75-liter V8 is prone to oil leaks, particularly from valve cover gaskets, rear main seal, and turbocharger oil lines (on Turbo models). Regular inspections are crucial.
  • Turbocharger Issues (Mulsanne Speed): High-performance variants might experience turbocharger problems, including failures due to excessive heat and oil starvation. Ensure proper maintenance and cooling.
  • Cooling System: Overheating can occur due to radiator clogging or thermostat failure. Regularly flush the cooling system and inspect the radiator for debris.
  • Transmission: The ZF 8-speed automatic transmission is generally robust, but occasional issues with shift harshness or hesitation can occur. Regular fluid changes are essential.
  • Air Suspension: Like many luxury cars, the air suspension can be a source of problems. Air struts can leak, and the compressor can fail. Listen for hissing sounds and ensure the car maintains proper ride height.

Electrical System

  • Infotainment System: The pre-facelift infotainment system can be outdated and prone to glitches. The facelift model's system is more modern and reliable.
  • Sensor Failures: Various sensors (e.g., parking sensors, oxygen sensors) can fail, leading to warning lights and diagnostic issues.
  • Battery Drain: Complex electronics can lead to battery drain if the car is left unused for extended periods. Consider using a trickle charger.

Interior & Body

  • Leather Wear: High-quality leather requires regular conditioning to prevent cracking and fading.
  • Wood Trim: Delicate wood trim can be scratched or damaged easily. Pay attention to the condition of the veneer.
  • Corrosion: While generally well-protected, check for signs of corrosion, especially in areas prone to moisture, such as around the windshield and door seals.

Driving Experience

The Mulsanne offers a unique driving experience, prioritizing comfort and refinement over outright sportiness. It is a car designed to be driven in, not just driven.

Pros:

  • Unparalleled Comfort: The ride is exceptionally smooth and quiet, thanks to the air suspension and extensive sound insulation.
  • Effortless Power: The 6.75-liter V8 provides immense torque, making acceleration effortless at any speed.
  • Handcrafted Luxury: The interior is a masterpiece of handcrafted leather, wood, and metal, creating a sense of opulence and exclusivity.
  • Presence and Prestige: The Mulsanne commands attention with its imposing size and elegant design.
  • Extended Wheelbase (EWB): The EWB model offers limousine-like rear legroom, making it ideal for chauffeured use.

Cons:

  • Size and Weight: The Mulsanne is a large and heavy car, which can make it feel cumbersome in tight spaces.
  • Fuel Consumption: Fuel economy is poor, especially in the Mulsanne Speed.
  • Running Costs: Maintenance and repairs can be expensive due to the car's complexity and the cost of parts.
  • Outdated Technology (Pre-Facelift): The pre-facelift infotainment system and driver-assistance features are less advanced than those found in newer luxury cars.
  • Limited Agility: While the Mulsanne is capable, it is not a sports car. Handling is focused on stability and comfort, rather than sharp cornering.

Buying Advice

Purchasing a used Mulsanne requires careful consideration. Here's some advice to help you make an informed decision:

Years to Look For:

  • 2016-2020 (Facelift Models): These models offer significant improvements in terms of styling, technology, and reliability. The updated infotainment system and revised suspension make them a more desirable choice.
  • Low Mileage Examples: Look for cars with well-documented service histories and relatively low mileage. This indicates that the car has been well-maintained and has not been subjected to excessive wear and tear.
  • Mulsanne Extended Wheelbase (EWB): If rear passenger comfort is a priority, the EWB model is the ultimate choice.

What to Avoid:

  • Neglected Examples: Avoid cars with incomplete service records, signs of neglect, or obvious mechanical issues. These cars are likely to require extensive and costly repairs.
  • Cars with Unexplained Warning Lights: Be wary of cars with warning lights illuminated on the dashboard. This could indicate underlying problems that require further investigation.
  • Modified Vehicles: Unless the modifications are professionally done and well-documented, avoid cars that have been heavily modified. Modifications can compromise the car's reliability and resale value.
  • Flood-Damaged Vehicles: Always check for signs of flood damage, such as water stains, corrosion, or a musty odor. Flood-damaged cars can be prone to electrical problems and other issues.

Pre-Purchase Inspection:

Before purchasing a Mulsanne, it is essential to have it inspected by a qualified Bentley technician. The inspection should include:

  • Comprehensive Mechanical Inspection: Check the engine, transmission, suspension, brakes, and other mechanical components.
  • Electrical System Check: Verify the functionality of all electrical systems, including the infotainment system, sensors, and lighting.
  • Diagnostic Scan: Perform a diagnostic scan to identify any stored fault codes.
  • Body Inspection: Inspect the body for signs of damage, corrosion, or prior repairs.
  • Interior Inspection: Check the condition of the leather, wood trim, and other interior components.
  • Test Drive: Take the car for a thorough test drive to assess its performance and handling. Pay attention to any unusual noises or vibrations.

By following this guide and conducting thorough research, you can increase your chances of finding a well-maintained Bentley Mulsanne that will provide years of luxurious driving pleasure.
