Alfa Romeo’s innovative (Twin Clutch Transmission) system is now also available in the Alfa Romeo Giulietta.
The transmission works in either a full automatic or sequential mode. The driver can manually change the gears either up or down utilising the paddle shifts on the steering column or gearshift for complete control. In addition, the driver can customise the car’s personality using the Alfa D.N.A. driving selector to enhance its features of comfort, performance, safety and efficiency.
The new Alfa TCT consists of “two gearboxes” in parallel, one for even gears and one for odd gears, each with its own clutch, which allows the selection and engagement of the subsequent gear while the previous one is still engaged. The gear is therefore changed with a simple, smooth yet very fast switching of the corresponding clutches, guaranteeing continuous torque delivery and therefore traction.
Consumption is reduced by up to 10% with respect to a traditional automatic gearbox. Alfa TCT uses dry clutches allowing, natural integration with Start&Stop, a function which is not always available with traditional automatic transmissions, and which guarantees a further benefit in terms of fuel consumption, particularly in cities.
The operation of the Alfa TCT is also designed to integrate the engine and the various onboard systems in the best manner. To allow for the best performance on the road, depending on the driving conditions and on the driver’s wishes, the transmission interacts with the Alfa D.N.A., braking system, engine control and vehicle stability control system (VDC).
