BorgWarner said it had started production of a new dual clutch module family to be used in the latest transmission from ZF.
Initially used in the dual clutch transmission for V6 and V8 biturbo petrol engines and a V8 biturbo diesel engine 'from major automakers' [which includes Porsche – ed], this transmission technology is also expected to be used in upcoming hybrid applications. Specifically designed for high-performance sports cars, this first European-built dual clutch module family was developed and produced in Germany. It offers improved durability and reliability and contributes to enhanced shift feel, the supplier said.

"We are pleased to expand our business collaboration with ZF by supplying our dual clutch modules," said Robin Kendrick, president and general manager, BorgWarner Transmission Systems. "[We] drew upon [our] extensive expertise in engineering transmission components to develop a modular high efficiency solution featuring a compact and low weight design. As a result, our dual clutch module is an ideal solution for sports cars and other high torque and high rev applications."
BW's new dual clutch module family is available with torque capacities of 570Nm, 700Nm and 1,000Nm and allows shifts within fractions of a second with no perceptible interruption of the power flow. The component uses high energy wet friction materials with a special groove design to minimise spin losses and provide improved heat resistance, high torque capacity and reliable operation over the transmission's lifetime. BW said, in combination with its tunable launch characteristics, the dual clutch module contributes to fuel economy comparable to single clutch automated gearboxes and shift quality to rival the best conventional automatic transmissions.
