Bentley 4.0 Twin-Turbo V8 Engine Specifications

The Bentley 4.0 Twin-Turbo V8 is a modern petrol engine developed for luxury vehicles requiring a combination of high-performance output and smooth power delivery. Its twin-turbocharged configuration helps produce substantial torque across a broad engine-speed range.

General engine specifications:

Specifications vary according to engine version, vehicle generation, market and model year. These are reference figures, not guaranteed specifications for every engine offered for sale.

Compatibility / Fitment Notes

The Bentley 4.0 Twin-Turbo V8 engine is associated with several Bentley vehicle applications. However, not every 4.0-litre V8 engine is a direct replacement for every vehicle.

Potential vehicle applications include:

• Bentley Continental GT V8: Selected models from 2012 onwards, depending on generation and market.

• Bentley Continental GTC V8: Selected convertible models equipped with the 4.0-litre twin-turbocharged V8.

• Bentley Flying Spur V8: Selected models from approximately 2014 onwards.

• Bentley Bentayga V8: Selected models from 2018 onwards.

Important engine compatibility considerations

Before ordering a replacement Bentley V8 engine, verify the following:

1. Engine code: Confirm the original engine code and replacement engine identification.

2. Vehicle generation: Match the engine to the correct Continental GT, Flying Spur or Bentayga generation.

3. Model year: Check the manufacturing year and applicable production updates.

4. Transmission compatibility: Verify compatibility with the vehicle's transmission and drivetrain configuration.

5. Engine electronics: Check ECU compatibility, wiring harnesses, sensors and engine management systems.

6. Turbocharger configuration: Confirm that the turbochargers and associated components match the required engine version.

7. Mounting and accessories: Verify engine mounts, cooling connections, exhaust connections and auxiliary components.

Providing your vehicle VIN and original engine code is the best way to establish whether a replacement engine is suitable.

Engine Configuration

The Bentley 4.0 Twin-Turbo V8 uses an eight-cylinder V-engine configuration designed to deliver high performance while maintaining smooth operation.

Its V8 architecture combines two cylinder banks with a twin-turbocharging system. Depending on the specific engine generation, supporting technologies include direct fuel injection, intercooling and advanced electronic engine management.

The turbocharging system increases the amount of air supplied to the engine, supporting higher power and torque output compared with a naturally aspirated configuration of similar displacement.

These characteristics make the 4.0-litre V8 suitable for Bentley's luxury grand touring vehicles and performance-oriented SUVs.

Engine Displacement

The engine has an approximate displacement of 4.0 litres.

Depending on the particular engine version, the displacement is listed as approximately 3,993 cc or 3,996 cc. The exact specification should be confirmed using the engine identification number and manufacturer's technical information.

This displacement provides the foundation for the engine's combination of performance, torque delivery and everyday driving capability.

Fuel Type

The Bentley 4.0 Twin-Turbo V8 is a petrol (gasoline) engine.

It uses a petrol fuel delivery system, with specifications and recommended fuel requirements varying by engine generation and market.

When purchasing a replacement engine, confirm that the fuel injection system, fuel rail, injectors and related components are appropriate for the intended vehicle.

Aspiration / Induction

The engine features a twin-turbocharged induction system.

Two turbochargers supply compressed air to the engine, supporting increased combustion efficiency and power production under appropriate operating conditions.

Depending on the specific version, the induction assembly may include:

• Twin turbochargers.

• Intercooling components.

• Intake manifolds.

• Turbocharger plumbing.

• Boost pressure control components.

• Electronic engine management systems.

The exact turbocharger and intake configuration should be checked before purchasing an engine assembly, particularly when sourcing a used or replacement powertrain.

Power Output

Power output varies across Bentley 4.0-litre twin-turbo V8 applications.

Earlier Continental GT V8 versions produced approximately 500 bhp, while later performance versions increased output. Selected modern conventional petrol versions, including the Continental GT V8 and Bentayga V8, produce approximately 542 bhp (550 PS).

The precise output depends on the engine calibration, vehicle generation and model specification.

Buyers seeking an engine replacement should identify whether their vehicle requires an earlier, standard or higher-output version rather than relying on displacement alone.

Torque

Torque is one of the defining characteristics of the Bentley 4.0 Twin-Turbo V8.

Depending on the application, torque figures range from approximately 660 Nm in earlier versions to 770 Nm in selected later conventional petrol versions.

This substantial torque output supports acceleration, smooth power delivery and the performance requirements of Bentley's luxury vehicles.

For an accurate replacement, ensure the torque specification matches the intended engine version and drivetrain configuration.

Years / Generation

The Bentley 4.0-litre twin-turbo V8 was introduced into the Continental GT range in 2012 and subsequently expanded across other Bentley models.

Its applications include:

• 2012 onwards: Introduction of the modern 4.0-litre V8 in the Continental GT range.

• 2014/2015 onwards: Selected Flying Spur V8 applications.

• 2018 onwards: Bentayga V8 applications.

• 2021–2024: Later-generation Continental GT and Flying Spur V8 applications, depending on market.

• 2025 onwards: New-generation hybridised 4.0-litre V8 applications in selected Bentley models.

Note that Bentley announced the retirement of its previous-generation conventional V8 from the Continental GT, Continental GTC and Flying Spur ranges in 2024, while the engine continued in the Bentayga family. Newer hybrid powertrains are not automatically interchangeable with earlier conventional petrol engines.

Why Choose a Genuine-Specification Bentley 4.0 V8 Replacement Engine?

When replacing a Bentley engine, matching the original engine specification is important for maintaining the intended vehicle configuration.

A suitable replacement engine should be evaluated based on:

• Correct engine identification and displacement.

• Compatible engine management and electronics.

• Matching turbocharger configuration.

• Appropriate transmission and drivetrain compatibility.

• Verified engine condition and operating history.

• Availability of relevant accessories and installation components.

Whether you are sourcing an engine for a Continental GT, Continental GTC, Flying Spur or Bentayga, accurate vehicle information helps reduce the risk of purchasing an incompatible unit.
