Yes, the current generation of the Audi RS4 is indeed twin-turbocharged.
The Audi RS4 B9 Engine: A Twin-Turbo Powerhouse
Specifically, the Audi RS4 Avant B9 generation is equipped with a powerful 2.9-liter Twin Turbo V6 engine. This V6 engine is a key component of its high performance, delivering significant horsepower and torque. The integration of two turbochargers allows for greater efficiency and power delivery across a broad RPM range, minimizing turbo lag and enhancing responsiveness.
The B9 generation marked a significant shift from the naturally aspirated V8 engines found in some earlier RS4 models, embracing forced induction for improved performance and fuel efficiency.

Benefits of Twin-Turbocharging in the RS4
The twin-turbo setup in the RS4 Avant B9 offers several advantages:
- Increased Power Output: Two turbos working in tandem provide more boost and therefore more power than a single-turbo setup, or a naturally aspirated engine of comparable size.
- Enhanced Torque Delivery: The system ensures robust torque is available from lower RPMs, leading to strong acceleration and flexible driving characteristics.
- Improved Efficiency: Despite the power increase, forced induction can also lead to better fuel economy compared to larger, naturally aspirated engines producing similar power.
- Optimized Responsiveness: By employing two smaller turbos, one for each bank of cylinders, the system can reduce turbo lag, making the engine feel more immediate and dynamic.
