Bentley presents a whole new 22 inch carbon fiber rim, developed specifically for the Bentayga SUV by Mulliner, its customization department. It was designed with Bucci Composites, one of the world’s leading composites suppliers, and will be the world’s largest production carbon wheel, which has many advantages in addition to its look: better safety, better steering agility and better stability, less tire wear, as well as better braking thanks to the reduction in unsprung mass.

Meeting strict TÜV standards (Technical Monitoring Association), it is the first carbon wheel to have passed all of the German body’s most rigorous tests for non-metallic wheels: biaxial stress, tire pressure, excessive torque, or even radial impact tests and lateral, to simulate traffic through potholes and cobblestones.

These are the most severe tests: after a violent impact, which should crack or break an aluminum wheel, which can cause the tire to explode, the Mulliner carbon fiber rim has proven its worth. stronger resistance, with a slow and progressive deflation of the tire, allowing to keep the control of the car.

Bentley Mulliner carbon fiber rims: tests at the Nürburgring

For the final stage, the carbon wheels of the Bentley Bentayga were also put to the test on the famous Nordschleife circuit of the Nürburgring. Besides the 6 kg weight gain, the carbon fiber allows to offer a better resistance and an additional rigidity.

To produce this unique rim, a new manufacturing process has been patented: the carbon fiber is cut, then the elements are assembled, stacked and heated in a mold, to give the final shape of the product. A specific resin and hardener are finally injected into the assembly, which is then temperature hardened before demoulding and finishing operations (machining and polishing).

This unprecedented carbon fiber rim is a real showcase for Mulliner, which highlights its know-how and its ability to provide Bentley customers with innovative and unique personalization elements. Available to order at the end of 2021, it will complete the range of carbon fiber parts designed for the Bentayga, made up of the front spoiler, the side sills and the rear diffuser, not to mention the carbon fiber interior inserts.
