⚙️ Engine Specifications
Primary Engine
Engine Type:
V8 (various displacements and configurations across models)
Engine Displacement:
Typically 6.75 Liters (6750cc) for most models, with variations in aspiration (naturally aspirated, turbocharged).
Engine Block Material:
Aluminum alloy or cast iron, depending on specific engine variant. Often featuring a robust, oversquare design.
Valvetrain:
Overhead valve (OHV) with hydraulic lifters. Timing is typically chain-driven for durability.
Performance
Horsepower Range:
Approx. 180-300 hp (naturally aspirated) to 300-400+ hp (turbocharged) depending on model and year.
Torque Range:
High torque output, characteristic of large displacement V8 engines, often exceeding 400-500 lb-ft, especially in turbocharged variants.
Fuel System
Fuel Injection:
Bosch K-Jetronic (CIS) or later electronic fuel injection (EFI) systems, depending on model year and specific engine variant.
Fuel Type:
Unleaded gasoline (Premium unleaded recommended).
🔧 Transmission
Standard
Transmission Type:
Hydraulic Automatic Transmission (e.g., GM TH400 or proprietary variations).
Optional
Optional Transmission:
Rarely offered manual transmissions, primarily for specific Bentley models or very early production runs.
Features
Transmission Features:
Smooth, powerful shifts, often with a torque converter lock-up feature for improved efficiency.
📐 Dimensions
Exterior
Wheelbase:
Varies by model, typically over 120 inches (e.g., Silver Spirit/Spur ~121.9 inches).
Overall Length:
Varies by model, generally large sedans and coupes, often exceeding 18 feet.
Body Styles:
Saloon (Sedan), Coupe, Convertible.
Weights
Curb Weight:
Typically in the range of 4,500 - 5,500 lbs (2040 - 2500 kg) due to robust construction and luxury appointments.
🛡️ Safety Features
Ratings
Safety Ratings:
No standardized crash test ratings (e.g., NHTSA/Euro NCAP) typically available for vehicles of this vintage; safety features focused on passive protection.
Active Features
Active Safety Features:
ABS (Anti-lock Braking System) became standard on later models.
Basic for the era, typically analog gauges, cassette players, or early CD players. Cooling system monitoring relies on temperature gauge and warning lights.
Driver Assistance
Driver Assistance Features:
Limited by modern standards. Cruise control standard on most models.
Connectivity
Connectivity Features:
Not applicable by modern standards; focus on mechanical systems.
🔧 Maintenance
Service Intervals
Cooling System Service Interval:
Coolant replacement typically every 2-3 years or 30,000-50,000 miles, depending on coolant type and manufacturer recommendation.
Fluid Specifications
Coolant Type:
Ethylene glycol-based antifreeze/coolant, often a specific blend recommended by Rolls-Royce/Bentley for corrosion protection. Consult manual for exact specifications (e.g., OAT or HOAT).
Coolant Capacity:
Approx. 10-14 Liters (10.5-14.8 US Quarts), varies by model and engine. Refer to manual for precise capacity.
Coolant Mixture:
Typically a 50/50 mixture of antifreeze and distilled water for optimal freeze and boil-over protection. Manual will specify exact ratio.
Known Issues
Common Cooling Issues:
Degradation of coolant hoses leading to leaks, failure of viscous fan clutch or electric fan motor, thermostat sticking, radiator corrosion, water pump seal failure, heater matrix leaks.
Corrosion Risks:
Potential for corrosion in aluminum components (radiator, engine block) if improper coolant or water is used.
