Discover the Bentley W12 Engine

Officially branded the Bentley W12 TSI, this iconic powerplant gets the W12 designation from its unique configuration: combining two VR6 cylinder banks in a compact W formation. This allows for a shorter, more rigid engine block and benefits vehicle dynamics and handling. The Bentley W12 has 6.0 liters of displacement and twin turbochargers, producing 552 to 700+ horsepower depending on the specific variant.

Bentley's brand has always been about ultimate performance and luxury; the Bentley W12 engine for sale here exemplifies this. From its distinctive sound to its effortless acceleration, the W12 engine embodies the very essence of Bentley , a blend of tradition and cutting-edge technology.

Understanding the W12 Configuration

The W12 is fundamentally different from a traditional V12 engine:

Traditional V12

• Two banks of 6 cylinders (each bank is a complete inline-6)
• Banks at 60° or 90° included angle
• Very long overall engine (often too long for most production cars)
• Used by Ferrari, Lamborghini (modern), Mercedes (older), Aston Martin

W12 (Bentley)

Two VR6 banks combined

Each VR6 is a narrow-angle V6 (15° between banks within the VR6) sharing a single cylinder head

The two VR6 banks combine at a 72° included angle

• Much shorter overall than a traditional V12 (~length of a V8)

Used by Bentley, Volkswagen Phaeton, Audi A8

W12 vs V8 Packaging Comparison

• Length: W12 is comparable to a V8 (significantly shorter than V12)
• Width: W12 is slightly wider than V8 due to the 72° angle
• Height: W12 is taller due to the cylinder bank arrangement

This packaging advantage allowed Bentley to fit 12 cylinders in chassis designed for V8 engines, providing the cylinder count and refinement of a V12 with the packaging flexibility of a V8.

W12 Engineering Features

The Bentley W12 engine for sale here features:

• W12 Configuration: Compact W formation combining two VR6 banks for smooth and powerful performance
• Twin-Scroll Turbochargers: Separate exhaust pulses to reduce lag and increase efficiency, two turbos total (one per cylinder bank)
• Active Cylinder Technology: Shuts off 6 of 12 cylinders at low load for better fuel economy without sacrificing performance when needed
• Integrated Exhaust Manifolds: Turbochargers mounted with exhaust manifolds integrated into cylinder heads, reducing weight and improving thermal characteristics
• Direct Injection (FSI): High-pressure fuel injection directly into combustion chambers for power and efficiency
• DOHC with Variable Valve Timing: Continuous valve timing adjustment for optimized performance across RPM range
• All-Aluminum Construction: Lightweight block and heads
• Premium Fuel Required: 93 octane mandatory for proper operation
