The Styling Specification includes a front bumper splitter, side skirts with metallic Bentley badges, rear diffuser and boot lid spoiler in high gloss carbon fibre.
The Bentayga package also includes a bi-plane tailgate spoiler and rear screen strakes, again all in high gloss carbon fibre, with the additional options of front air blades, wing vents and mirror caps in a matching finish.
The carbon fibre weave is a 2x2 twill pattern, woven in the same direction for all components to ensure consistency.
The side skirts include a three-dimensional electroformed Bentley badge.
The Styling Specification complements the aerodynamic performance of the Continental GT family and Bentayga.
The first designs are assessed 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 seeks to minimise any affect that the carbon fibre parts may have on vehicle systems from PDC (park distance control) to radar systems and antennae for on-board communications and entertainment.
Only once these virtual assessments are complete are the first physical prototypes manufactured, before being refined in the wind tunnel and on the test track.
The parts are also assessed across all driving conditions up to and including top speed, for stability, feel and performance under both acceleration and braking to ensure that the Bentley driving dynamic is not degraded.
Once functionality is signed-off, the parts are assessed through a variety of validation tests. These include durability programmes – including overall vehicle tests of 100,000km - to abuse testing such as wading, kerb strikes, and rough roads.
Rig testing in Bentley’s Quality lab assesses performance through the rigours of vibration, thermal cycling, point loading and impacts.
