Automotive manufacturers are increasingly turning to alternative materials to create wheels for vehicles that are stronger and lighter. In the past, wheels were typically made from aluminum alloy. However, it is becoming more and more common for wheels on sports cars and high-end vehicles to be made from carbon fiber. Bentley Mulliner has announced the development of 22-inch carbon fiber wheels for the Bentayga SUV.
Bentley says each wheel saves six kilograms of unsprung mass per wheel compared to aluminum. The beautiful wheels are manufactured in cooperation with composite manufacturer Bucci Composites. It took five years of engineering to deliver the first carbon fiber wheel capable of passing TUV testing.
Advantages of Carbon Fiber Wheels
Bentley’s wheels have increased impact safety due to the material dispersing air loss. This is particularly important in high-performance vehicles where maintaining tire pressure can be critical for both safety and performance. The wheels also have an improved stiffness equivalent to one degree in camber per 1G of force. This increased stiffness not only enhances the vehicle’s handling but also contributes to a more responsive driving experience.
Another interesting promise is that the stiffness of the wheel will lead to reduced tire wear. This is because the rigidity of the carbon fiber helps to maintain the tire’s shape and contact patch with the road, reducing uneven wear and extending the life of the tires. This can be a significant cost-saving measure over the life of the vehicle, especially for high-performance cars that often go through tires more quickly.
Engineering and Development
The development of these carbon fiber wheels was no small feat. It took five years of rigorous engineering and testing to ensure that the wheels could meet the stringent requirements of TUV testing, a certification process that ensures the safety and reliability of automotive components. This involved extensive simulations and real-world testing to ensure that the wheels could withstand the stresses and strains of everyday driving as well as high-performance scenarios.
The collaboration with Bucci Composites, a leader in composite materials, was crucial in achieving this milestone. Bucci’s expertise in carbon fiber manufacturing allowed Bentley to push the boundaries of what is possible with this advanced material. The result is a wheel that not only meets but exceeds the performance and safety standards expected of a luxury vehicle like the Bentayga SUV.
Bentley’s commitment to innovation is evident in this development. By investing in new materials and technologies, they are able to offer their customers a product that enhances both the performance and aesthetics of their vehicles. The carbon fiber wheels are not just a functional upgrade; they are a statement of Bentley’s dedication to pushing the envelope in automotive engineering.
The wheels will be available to order through Mulliner later this year at unannounced pricing. While the cost is likely to be high, given the advanced materials and engineering involved, the benefits in terms of performance, safety, and tire longevity make it a worthwhile investment for those who demand the best from their vehicles.
The shift towards carbon fiber wheels represents a significant advancement in automotive technology. These wheels offer numerous benefits over traditional aluminum alloy wheels, including weight savings, improved safety, enhanced handling, and reduced tire wear. Bentley’s new 22-inch carbon fiber wheels for the Bentayga SUV are a prime example of how innovation and engineering excellence can come together to create a superior product. As more manufacturers explore the potential of carbon fiber, we can expect to see even more exciting developments in the world of high-performance and luxury vehicles.
