Key Features and Technologies
1. Supercharged V6 Performance
The CGW engine uses a roots-type supercharger mounted in the V of the engine block. Unlike turbocharged engines, this configuration provides instant boost with no turbo lag, delivering immediate throttle response and consistent power across the entire RPM range.
2. Strong Power and Torque Output
With 245 kW (333 hp) and 440 Nm of torque, the CGW engine delivers rapid acceleration and confident overtaking. In the Audi S4, this powertrain enables a 0–100 km/h time of approximately 5 seconds, positioning it firmly in the performance sport sedan category.
3. Efficient Direct Injection
Audi’s TFSI direct fuel injection system optimizes combustion efficiency, resulting in improved fuel economy and reduced emissions while maintaining strong performance characteristics.
4. Advanced Thermal Management
An integrated supercharger cooling system ensures stable operating temperatures, even under sustained high-load conditions, supporting consistent power delivery and long-term reliability.
5. Audi Drive Select Integration
The CGW engine is fully compatible with Audi Drive Select, allowing drivers to adjust throttle response, transmission behavior, and steering feel to match Comfort, Dynamic, or Individual driving modes.
Applications and Engine Compatibility
The Audi 3.0 TFSI (2995 cc) supercharged V6 engine family was installed across multiple Audi platforms with different power outputs and engine codes. All variants share the same base architecture, with differences mainly in ECU calibration and vehicle application.
