The New Bentley Flying Spur's Ultra Performance Hybrid Powertrain: Everything You Need to Know
December 20 2024,
The heart of the 2025 Bentley Flying Spur beats with an all-new Ultra Performance Hybrid powertrain that combines advanced V8 technology with electric propulsion. This innovative system delivers 771 hp of combined power and 737 lb-ft of torque, making it the most powerful system ever fitted to a Bentley sedan.
V8 Engine Technology
The foundation of this hybrid powertrain is an advanced 4.0-litre twin-turbocharged V8 engine producing 592 hp and 590 lb-ft of torque. The engine features significant technological innovations, including an increased fuel injection pressure of 350 bar, up from the previous 200 bar, enabling more precise fuel delivery and cleaner combustion.
Bentley engineers have implemented twin single-scroll turbochargers, a departure from traditional twin-scroll units. These new turbochargers operate at higher temperatures, optimizing performance while reducing emissions. The removal of cylinder deactivation hardware streamlines the engine design, as the electric motor handles low-load driving situations.
Electric Motor Integration
The electric motor component delivers 187 hp and 332 lb-ft of torque, seamlessly integrated within the eight-speed dual-clutch transmission. This placement optimizes weight distribution and ensures direct power delivery. The motor can propel the Flying Spur at speeds up to 140 km/h in pure electric mode, with throttle applications of up to 75 percent available before the V8 engine engages.
The battery system supports this performance with a 25.9 kWh capacity, providing up to 76 km of pure electric range. The charging system can replenish the battery fully in as little as 2.75 hours, with 11 kW peak charging power ensuring quick turnaround times between drives.
Combined Performance Capabilities
The integration of combustion and electric power creates remarkable performance metrics. The instant torque from the electric motor eliminates traditional turbo lag, while the V8 engine provides sustained high-end power. This combination enables the Flying Spur to accelerate from 0 to 100 km/h in just 3.5 seconds, with seamless power delivery throughout the acceleration range.
The total system output of 771 hp represents a 19 percent increase over the previous generation, while the 737 lb-ft of torque marks an 11 percent improvement. The powertrain maintains this performance while enabling a total driving range of 829 km, combining high performance with practical usability.
Power Management Systems
The sophisticated powertrain management system coordinates the interaction between the V8 engine and electric motor through multiple driving modes. The system manages energy flows based on driving conditions and selected modes, optimizing performance or efficiency as needed.
A dedicated charge mode allows the V8 engine to simultaneously power the wheels and charge the battery. The system's electronics constantly monitor power requirements, battery state of charge, and driver inputs to determine the optimal power source for any given situation. The integration of regenerative braking helps recover energy during deceleration, feeding power back into the battery system.
The Ultra Performance Hybrid powertrain indicates a new benchmark in luxury performance engineering. By combining advanced V8 technology with sophisticated electric propulsion, Bentley has created a system that delivers exceptional performance while reducing environmental impact. This powertrain demonstrates how hybrid technology can enhance rather than compromise the performance capabilities of premium luxury vehicles.
