FYI: Bentley commemorates the end of an era as the final W-12 engine rolls off the production line, making way for a new V-8 plug-in hybrid powertrain.
Bentley Bids Farewell to Iconic W-12 Engine
Bentley has officially ended the production of their revered W-12 engine after two decades of innovation and performance. On Tuesday, the final unit was completed at the Crewe, U.K. plant, marking the end of an era for the luxury automaker.
The Last of its Kind
The last W-12 is also the most powerful ever built, boasting an impressive 740 horsepower. This engine will grace one of Bentley’s exclusive Batur models, a bespoke creation that not only celebrates the W-12 legacy but also hints at design cues for Bentley’s upcoming electric vehicle, set to debut in 2026. To honor the engine’s legacy, Bentley also released a series of Speed 12 special editions last year.
A Legacy of Innovation
First introduced in the original Continental GT, the twin-turbocharged 6.0-liter W-12 quickly became a symbol of Bentley’s engineering prowess. Over time, more than 100,000 units were produced, making it the most successful 12-cylinder engine of the modern era. The W-layout – effectively two V-6 engines on a single crankshaft – allowed the engine to be 25% shorter than a traditional V-12, enhancing its packaging and efficiency. This innovative design was also employed by Bugatti for their W-16 engine, which powered the legendary Veyron and Chiron hypercars.
Rigorous Testing and Exceptional Skill
Bentley’s dedication to quality was exemplified by the rigorous testing and skilled craftsmanship involved in producing each W-12 engine. A dedicated team of 30 specialists devoted approximately 6.5 hours to build each unit. The engine underwent extreme durability tests, including running at full throttle for 100 hours repeatedly, simulating 20,000 miles at 200 mph. Another test pushed the engine to redline 100 times within 30 seconds of starting at a frigid 14 degrees Fahrenheit, ensuring unparalleled reliability and performance.
A Green Future Ahead
As Bentley looks towards a greener future, the W-12’s replacement is a V-8 plug-in hybrid powertrain, recently debuted in the updated Continental GT Speed. This new powertrain delivers an impressive 771 horsepower and will be featured in the refreshed Flying Spur Speed. Anticipation is high as Bentley prepares to integrate lower-rated versions of this hybrid powertrain across their entire lineup.
Conclusion
The end of the W-12 era marks a significant milestone for Bentley as they transition towards fully electric vehicles by the end of this decade. The enduring legacy of the W-12 engine will be remembered as a pinnacle of automotive engineering, setting a high bar for future innovations.
