Self Study Program 198 – The 2.7L V6 Biturbo

VAG SSP 198.  Turbocharged engines are already something of a tradition at AUDI. The task now facing AUDI’s engineers was to develop a worthy successor to the 5-cylinder turbocharged engine.

One of the key development goals for the turbocharged engine was to achieve a good level of dynamic response, particularly at the bottom end of the rev band.

The goal of AUDI’s engineers was to realise a high “basic torque level“ and a torque  characteristic that rises in direct proportion to engine speed to its peak.

The term “basic torque level“ describes the torque which is immediately available when the throttle is opened (e.g. at part throttle or in overrun).
