Italians win big with new Aston Martin One-77
Italian suppliers Brembo, Pirelli and Oerlikon Graziano have key parts in the new Aston Martin One-77. The 750-hp supercar has a high-performance automated manual transmission that Oerlikon Graziano exclusively designed for the One-77.
The transaxle configuration provides the car with a 48:52 weight distribution, which improves handling, while the aluminum transmission housing has been designed for high rigidity and low weight.
The transmission's cylindrical gears are coated with the company's so-called Balinit C, a special treatment used to reduce friction. This reduces wear and allows the system to withstand high loads despite low lubrication or even dry running. Triple and double cone synchronizers are used to provide fast shifts.
Brembo fits the One-77 with its so-called "CCM" discs and brake calipers. The discs are made from a carbon fiber compound that is impregnated with silicon then baked in a mold at 1,700 degrees Celsius. Brembo says the carbon fiber discs are much tougher than conventional cast iron discs and that they can dissipate heat much more rapidly, which reduces brake fade.
The brake rotors are mounted on to disc bells using a so-called "floating disc" system. According to Aston Martin, this allows the discs to flex relative to their mountings, making them less prone to vibrate.
The CCM brakes are about 12.5kg lighter than a conventional system, Brembo says.
TI Automotive of the UK also helps with the One-77's brakes by supplying the brake lines and brake booster vacuum lines in addition to the fuel lines. The supercar uses Italian supplier Pirelli's PZero Corsa tires. Gti of the UK helps keep the One-77's interior quiet by providing seals for the doors, windshield, rear window, inner and outer waist belt, hood and trunk lid.
Aston Martin plans to make just 77 units of the One-77 vehicles at its factory in Gaydon, England.
