The Volkswagen-Audi Group 4.0L TFSI V8 Architecture
The Bentley 4.0L V8 is part of one of the most important modern luxury performance engine families. The same fundamental 4.0L V8 architecture powers:
Bentley Applications
Bentley Continental GT V8 (2012-2024): The flagship V8 application, ~542 HP
Bentley Continental Flying Spur V8 (2014-2020): 4-door saloon variant
Bentley Bentayga V8 (2018-2024): The luxury SUV V8 application
Bentley Bentayga Speed V8: Higher-tuned variants at 626 HP
Audi Applications
Audi RS6: 560-630 HP performance station wagon and sedan
Audi RS7: Similar tuning to RS6 in 4-door coupe form
Audi S6 / S7: 4.0 TFSI V8 in lower-tuned 444 HP form
Audi S8: 4.0 TFSI V8 in higher-tuned 520+ HP form (the Audi S8 is the most directly comparable Audi to the Bentley V8 applications)
Porsche Applications
Porsche Panamera Turbo / Turbo S: 4.0L V8 twin-turbo in 550-630 HP form
Porsche Cayenne Turbo: 4.0L V8 in SUV applications
Porsche Panamera Turbo Hybrid: 4.0L V8 with electric hybrid system
Lamborghini Applications
Lamborghini Urus: 4.0L V8 in highest-tuned 641 HP form (the most aggressive tuning of this engine family)
The hot-V architecture, ECU programming, intake, exhaust, and ancillary components vary between manufacturers, but the core engine architecture is shared. This represents significant economies of scale for VW-Audi Group’s luxury performance engineering.
What Makes Each Application Distinct
Bentley character: Tuned for refinement and luxury, smoother power delivery
Audi RS character: Tuned for aggressive performance, sharper response
Porsche character: Tuned for sports car precision, more aggressive sound
Lamborghini character: Tuned for maximum power, most aggressive exhaust note
For replacement applications, the Bentley-specific variant must be matched.
The Hot-V Configuration , A Defining Feature
A signature characteristic of the Bentley 4.0L V8 is the hot-V layout:
What is Hot-V Configuration
In a traditional V engine, the turbochargers are typically mounted on the outside of the V (between the cylinder heads and the chassis). In a hot-V configuration, both turbochargers are mounted inside the V , between the two cylinder banks.
Benefits of Hot-V Configuration
1. Faster turbo response: Shorter exhaust manifold path = less heat loss and quicker spool
2. More compact packaging: The engine fits in smaller bays
3. Simpler intake routing: Air intake comes from outside the V (more direct path)
4. Better thermal management: Engineered thermal isolation between hot exhaust side and cool intake side
5. Improved low-RPM response: Less turbo lag at low engine speeds
Trade-offs
1. More complex thermal management: Heat from turbos affects engine bay temperatures
2. More complex valve cover and accessory routing: Different from traditional V8 layouts
3. Specialized service requirements: Accessing turbos requires more disassembly
This hot-V configuration has become a signature feature across the VW-Audi Group 4.0L V8 family, distinguishing it from earlier traditional V8 designs.
