(Crewe, August 26, 2020) Bentley introduces a new styling specification for the Flying Spur, allowing customers to highlight the sporty credentials of the world’s fastest production sedan and give the car an even sportier aesthetic to match to its unmatched performance.
The Flying Spur sets the benchmark for luxury agility and dynamism using the latest chassis technology, including active all-wheel drive, all-wheel steering, torque vectoring and 48V electric anti-roll bar system – introduced for the first time by Bentley. The aesthetic of the new styling specification complements the unparalleled capabilities of the Flying Spur, ensuring that Bentley’s new flagship is as stunning as it gets to drive.
Handcrafted of high-gloss carbon fiber to exact tolerances following an extensive development program, the styling specification includes a front bumper splitter, side skirts with metallic Bentley badges, rear diffuser and spoiler trunk.
Improved athletic appeal
Like the veneer that adorns the cabin space, the carbon fiber exterior components match the mirrors on the car’s centerline for precise visual appeal. The carbon fiber weave is a 2×2 twill pattern, woven in the same direction for all components to ensure consistency. Carbon fiber is laid out in multiple layers, each oriented for optimum strength and durability while maintaining minimal weight.
The side skirts feature an exquisite detail with the inclusion of a three-dimensional electroformed Bentley badge. The badge profile was developed especially for the style specification, to minimize the risk of air bubbles forming in the lacquer overcoat while providing an eye-catching faceted appearance.
The styling specification is specially designed to complement the aerodynamic performance of the Flying Spur. Early designs are evaluated and refined using computational fluid dynamics (CFD) software for aerodynamic performance, including front and rear lift and overall drag. Simulations are also made of the effect on powertrain cooling, brake cooling and noise, vibration and harshness (NVH). Electrical testing aims to minimize any effect that carbon fiber parts can have on vehicle systems, from PDC (Park Distance Control) to radar systems and antennas for onboard communications and entertainment.
It is only after these virtual evaluations are completed that the first physical prototypes are manufactured, before being refined in the wind tunnel and on the test track. Parts are also rated under all driving conditions up to and including top speed, for stability, feel and performance under acceleration and braking to ensure that Bentley driving dynamics are maintained.
Once the functionality is validated, the parts are evaluated through various validation tests. These include durability programs – including overall 100,000 km vehicle tests – to abuse tests such as the paddling pool, sidewalk collisions and rough roads. Bench testing in Bentley’s quality lab assesses performance through the rigors of vibration, thermal cycling, point loads and impact.
After all test and development work is complete, the manufacturing process is refined over a number of development cycles to provide consistent and repeatable manufacturing tolerances that meet the exacting demands expected of a Bentley. 3D scanning and comparison with a nominal metrology buck assess the manufacturing accuracy.
Styling specifications can be ordered through the Bentley dealer network and can be specified when a new car is ordered or upgraded at a later date to improve a customer’s existing car.
Performance-oriented driving dynamics
When the new Bentley Flying Spur was introduced in 2019, it set a new benchmark in performance, agility and dynamism. A key element in the design of the new Flying Spur has been to move the front axle position forward to improve weight distribution, allowing for dynamic precision, improved handling and balance when paired with active all-wheel drive, all-wheel steering and Bentley Dynamic Ride.
Depending on the road conditions, the powertrain can vary up to 480 Nm of torque from the rear of the car to the front axle providing better grip and handling, thanks to the active all-wheel drive system. The front now feels a lot lighter and the cornering response is also significantly improved. The understeer effect felt with the fixed all-wheel drive is virtually eliminated, giving the car an overall feeling of balance.
The torque distribution varies depending on the selected drive dynamics mode. In Sport, the system limits the torque available on the front axle to 280 Nm, maintaining a higher level of torque at the rear for a more dynamic feel. The torque is also managed on each axle by a torque vectoring system by brake.
Electronic all-wheel steering improves both stability at highway speeds and handling in town. When maneuvering at low speed, the system steers the rear wheels away from the front wheels. This has the effect of shortening the wheelbase, reducing the turning radius almost to that of the Continental GT, increasing agility and making parking noticeably easier.
When maneuvering at high speed, the system steers the rear wheels in the same direction as the front wheels, increasing stability and making overtaking and lane changes more confident. Electronic all-wheel steering means no compromise between confidence at high speeds and convenience at low speeds.
The Flying Spur uses three-chamber air springs that contain 60% more air volume compared to the previous model. This allows more possibilities to vary from sporty levels of spring stiffness to luxury limousine refinement depending on the mode selected by the driver. The new car is equipped with CDC (Continuous Damping Control), which allows continuous regulation of the shock absorbers.
Four ride height sensors continuously measure the distance between the axle and the body. If the system detects a difference from the normal height, the air volume in the springs is corrected accordingly to restore the normal height.
The Bentley Dynamic Ride system is designed to improve both handling and ride comfort. A 48-volt system controls an electronic actuator unit that manages the stiffness of the anti-roll bar, altering stiffness on demand to combat cornering forces and maintain Flying Spur level.
