History

Graziano Trasmissioni was started in 1951 as a small family company with 15 employees by Carlo Graziano. In 1963, the company moved to its present headquarters in Cascine Vica. After 1981, the company's export activity increased progressively. The company then expanded, opening a factory in India in 1999, another in Suzhou (China) in 2006 and a third in Červený Kostelec (Czech Republic), in 2006.

In 2007 it merged with North American Fairfield, becoming Oerlikon Drive Systems, part of the Oerlikon Group.

Applications

From 1996-1997, starts the cooperation with Ferrari, it developed and supplied the complete gearboxes for the Ferrari 360, 612 Scaglietti, Enzo, F430, 575M Maranello.

The Lamborghini Aventador uses a single-clutch lightweight 7-speed automated manual gearbox built by Graziano.[7][8] Despite being single-clutch, gear-shifts are accomplished in 50ms. The Gallardo and the first-generation Audi R8 used a mid-engine Graziano gearbox (manual or automated manual versions).

The DCT gearbox used in the Audi R8 was developed in partnership with Graziano. It is built and pretested at Graziano's Luserna plant in Italy before shipment to Volkswagen's Kassel plant in Germany, where the clutch and mechatronics modules are added. The finished transmission is then sent to Audi.[9]

The Aston Martin One-77, Vantage S, V8 Vantage, Aston Martin DB9 and Maserati GranTurismo S use rear-transaxle gearboxes, while the Maserati Quattroporte and Coupé & Spyder Trofeo- GranSport had an MT-AMT automated manual gearboxes.

The 2014 McLaren 650S uses the second generation of the SSG, with revised software which improves shifting times by further 0.3s.[10]

The 2020 Aston Martin Victor use rear-transaxle Manual gearbox.[citation needed]
