Rust can appear in common areas, particularly if the vehicle has not been garaged, and older rubber components invariably degrade, leading to various leaks and performance degradation.
1990 Bentley Turbo: Quick Overview
Engine Options:
- 6.75-liter (6,750 cc) Rolls-Royce V8 engine, turbocharged. This was the sole engine option for the Turbo R.
Horsepower:
- While officially "sufficient" by Rolls-Royce/Bentley tradition, power output for the 1990 model was estimated to be around 328-335 hp (245-250 kW). Earlier Turbo R models had lower official outputs, but by 1990, enhancements were made.
Torque:
- Significant torque figures, often exceeding 450 lb-ft (610 Nm), crucial for its effortless acceleration.
Fuel Economy:
- Not a strong point. Expect single-digit MPG figures in city driving, typically around 8-12 MPG (US) or 19-29 L/100km. Highway figures might reach 15-18 MPG (US) under ideal conditions, but this is a very thirsty vehicle.
0-60 MPH Times:
- Despite its substantial weight (around 5,300 lbs or 2,400 kg), the turbocharged V8 provided surprisingly brisk acceleration. 0-60 mph times were typically in the low 7-second range, often around 6.5 to 7.0 seconds, which was very quick for a luxury saloon of its size and era.
Towing Capacity:
- Towing was not a primary design consideration for the Bentley Turbo R, and official towing capacities are rarely published or recommended. Due to its luxury nature and sophisticated suspension, it is generally not considered suitable for towing, and owners typically avoid such use.
Trim-Level Features (Standard for Turbo R):
- Suspension: Advanced hydraulic self-leveling suspension with firmer damping than the Mulsanne, providing improved handling.
- Brakes: Four-wheel disc brakes with ABS were standard.
- Interior: Exquisite hand-stitched leather upholstery throughout (often Connolly leather), extensive wood veneer trim (usually burr walnut), deep pile wool carpets.
- Seating: Electrically adjustable front seats with memory function. Rear seats offered substantial legroom.
- Climate Control: Dual-zone automatic climate control.
- Audio System: Premium audio system for the era, often with a cassette player and later CD changer options.
- Power Features: Power windows, power mirrors, power steering.
- Wheels: Alloy wheels specific to the Turbo R, designed to accommodate larger brakes.
- Safety: Front airbags were not universally standard in 1990 but began appearing later in the production run. ABS was a key safety feature.
- Exterior: Subtle "Turbo R" badging, redesigned front air dam, and a slightly lower stance compared to its non-turbo counterparts.

What Problems Does the 1990 Bentley Turbo Have?
The 1990 Bentley Turbo R, while a magnificent machine, comes with a legacy of frequently reported problems and long-term reliability concerns, primarily due to its complexity and age. The most infamous issue centers around the high-pressure hydraulic braking and suspension system, often referred to as the 'Mineral Oil System' (MOS) or 'Green Blood System.' Leaks are common from pipes, accumulators, and hydraulic pumps, leading to costly repairs. A failing suspension sphere can result in a harsh ride, while a loss of pressure affects both ride quality and braking effectiveness, potentially creating a dangerous situation. These components are expensive to replace, and specialized knowledge is required for proper servicing.
Another significant area of concern is the electrical system. These cars are replete with intricate wiring, relays, and switches which, over decades, can degrade. Common issues include power window failures, erratic gauge readings, climate control malfunctions, and various dashboard warning lights illuminating without apparent cause. Tracing these electrical gremlins can be time-consuming and expensive.
Engine-related issues, while less common for the robust Rolls-Royce V8 itself, can arise from peripheral components. Oil leaks, particularly from valve cover gaskets and crankshaft seals, are frequently reported. The turbocharger unit itself is generally reliable but can fail if oil changes are neglected or if the engine is not properly cooled down after hard driving. Overheating is a potential issue if the cooling system, including the radiator and hoses, is not meticulously maintained.
Rust can be a problem, especially on vehicles exposed to harsh climates or inadequate storage. Common areas include wheel arches, sills, and around window frames. Interior components, such as wood veneers, can crack or delaminate, and leather upholstery can show wear, cracking, or fading. While not 'problems' in the mechanical sense, these require significant investment to restore.
As for recalls specific to the 1990 model year, major recalls affecting the entire Turbo R range over its production run typically related to minor safety components or regulatory compliance rather than widespread mechanical failures. For instance, some models had recalls for seatbelt components or lighting issues. However, the biggest 'watch out' is the general wear and tear of a complex, aging luxury vehicle rather than a single, universally applicable recall issue for the 1990 model. Prospective buyers should always check a vehicle's VIN for any outstanding recalls.

How long will the 1990 Bentley Turbo last?
A well-maintained 1990 Bentley Turbo R can last for many years and accumulate significant mileage, with examples often exceeding 150,000 to 200,000 miles. However, achieving this longevity demands exceptionally diligent and costly maintenance habits. Owners who treat these cars as disposable or neglect regular servicing will find their vehicle quickly becoming a money pit or completely unreliable. The long-term durability of the core engine and transmission is generally good, provided oil changes and fluid checks are performed religiously.
The weaknesses over time manifest primarily in the hydraulic system's components and the vast electrical network. Rubber seals, hoses, and wiring insulation degrade, leading to leaks, shorts, and system failures. Restoration of these elements is often necessary for long-term enjoyment and reliability. Ultimately, the car's lifespan is less about its inherent design and more about the owner's willingness to invest in its specialized care.

Driver-Assistance Features:
- Driver-assistance features as we know them today (e.g., adaptive cruise control, lane-keeping assist) simply did not exist in cars of this vintage. The primary 'assistance' came from robust engineering and a commanding driving position.
Safety Features:
- Anti-lock Braking System (ABS): A cutting-edge safety feature for its time, standard on the Turbo R, significantly improving braking control in adverse conditions.
- Driver's Airbag: While not universally standard at the start of the Turbo R's production, a driver's side airbag became an increasingly common, and later standard, feature for the 1990 model year in key markets like the USA. Passenger airbags were still rare.
- Reinforced Chassis: The car's sheer mass and robust construction offered a degree of passive safety.
- Seatbelts: Three-point seatbelts were standard for front and rear outboard passengers.
Optional Features:
- Beyond the standard extensive luxury, customization options were vast, allowing owners to choose specific leather colors, wood veneers, special paint finishes, and bespoke interior appointments. An upgraded audio system or early car phone integration might have been factory or dealer options.
Crash-Test Ratings:
- Modern independent crash-test ratings (like those from NHTSA or IIHS) were not conducted on ultra-low volume, hand-built luxury vehicles like the Bentley Turbo R. Therefore, specific crash-test ratings are unavailable. The vehicle's inherent structural rigidity and heavy construction would have provided a good level of occupant protection for its era, though it lacks the sophisticated crumple zones and multiple airbags of modern vehicles.

1990 Bentley Turbo Prices and Market Value
When new, the 1990 Bentley Turbo R commanded an astonishing price, often exceeding £100,000 in the UK and well over $150,000 in the US, adjusting for exchange rates. This placed it firmly in the ultra-luxury segment, making it exclusive to a very affluent clientele.
Today, the used market prices vary wildly based on condition, mileage, and service history. Well-maintained examples in excellent condition can fetch anywhere from $25,000 to $50,000, and exceptionally pristine, low-mileage examples or those with significant historical provenance might exceed $60,000-$70,000. Conversely, projects or cars with neglected maintenance can be found for as little as $10,000 to $15,000, though these typically require substantial investment.
Depreciation from its new price was astronomical, as is typical for most ultra-luxury cars. The initial owner bears the brunt of this decline. Factors affecting resale value now include the completeness and accuracy of its service records (especially regarding the hydraulic system), the cosmetic condition of the interior wood and leather, absence of rust, and overall mechanical soundness. A "running project" will always command a much lower price than a meticulously maintained example ready for concourse or regular driving.

1990 Bentley Turbo Cost of Ownership
Ownership of a 1990 Bentley Turbo R is far from economical; it is unequivocally a costly vehicle to maintain and operate. Insurance premiums will be high due to its value, performance, and the cost of parts, often requiring specialized classic car policies. Fuel costs are significant, given its 6.75-liter turbocharged V8 engine's thirst, consistently delivering single-digit to low-teen MPG figures. Maintenance is where the true cost lies. Routine servicing alone will be several times that of a mainstream car, and specialized Bentley technicians charge premium rates.
Repairs, particularly for the hydraulic suspension or complex electrical issues, can easily run into thousands of dollars for a single fix, often due to labor-intensive diagnostic work and expensive proprietary parts. Long-term ownership demands a substantial annual budget set aside purely for its upkeep. This car is a passion purchase, not an economical mode of transport.
