s with regard to all V6 engines for power and torque the characteristics mentioned above. ratings of 200 bhp and 300 Nm respectively. Basic principle Set of primary pulleys The key ponent part of the multitronic? is pulley set 1 the variator. It allows reduction ratios to be Set of secondary pulleys adjusted continuously between the starting pulley set 2 torque multiplication ratio and the ?nal torque multiplication ratio. As a result, a suitable ratio is always available. The engine can always operate within the optimum speed range regardless of whether it is optimised for performance or fuel economy. The variator prises two tapered disc pairs a set of primary pulleys pulley set 1 and a set of secondary pulleys pulley set 2 as well as a special chain which runs in the Vshaped Drive gap between the two tapered pulley pairs. The chain acts as a power transmission Downforce element. Pulley set 1 is driven by the engine by means Narrow of an auxiliary reduction gear step. Engine torque is transmitted via the chain to pulley set 2 and from here to the ?nal drive. One of the tapered pulleys in each of the sets of pulleys can be shifted on the shaft for variable adjustment of the chain track diameter and transmission ratio. 228_043 The two sets of pulleys must be adjusted simultaneously so that the chain is always taut and the disc contact pressure is suf?cient for transmission purposes. Wide This gearbox a is known as a chain drive transmission because of its design. 5 Introduction multitronic? for imum fort In automatic mode, any ratio is possible within the bounds of the control map. The factors that determine rpm are driver input 228_007 accelerator pedal position and actuation rate and traction resistance. Transmission ratios are adjusted pletely free of jolts and without any interruption in tractive power ?ow. In the tiptronic function, there are 6 de?ned shifting characteristics for manual gear selection. The driver can therefore choose 228_038 handling dynamics to suit his/her personal preferences. This feature is particularly useful on downhill gradients for example, as the driver can personally determine the engine braking effect by selective downshifting. 228_015 Top speed is achieved in 5th gear. 6th gear is con?gured as an economy gear or overdrive. The tiptronic can be operated from the steering wheel at makes the tiptronic function very userfriendly indeed.
