More displacement means more power and torque across the powerband, enabling RS models to rocket from 0-60 mph in under 4 seconds in some cases.

Turbocharging and Supercharging

In addition to displacement, RS powertrains utilise forced induction via turbocharging or supercharging to boost power output. The RS 6 Avant’s 4.0L V8 makes a whopping 591 horsepower thanks to twin turbochargers. RS models also employ larger, more capable turbochargers compared to S models. This forced induction gives RS engines immense power while maintaining efficiency.

Performance-Focused Engineering

RS powertrains are engineered for ultimate performance. Components like the crankshaft, pistons, valves, and camshafts are built to withstand higher combustion pressures and temperatures. RS models also utilise high-flow intake and exhaust systems to optimise breathing. These bespoke RS components work together to extract every ounce of power from the engine.

Advanced Technology

Cutting-edge tech further propels RS models. For example, the RS 3 features a motorsport-derived 5-cylinder with dual injection and adaptive valve lift. Other RS models utilise cylinder deactivation for improved efficiency. RS powertrains also integrate launch control, over boost functions, and performance all-wheel drive systems like Quattro with Sport Differential. This technology amplifies RS performance capabilities.

In summary, RS models truly earn their “Racing Sport” designation with substantially more powerful engines compared to S models. This power advantage is achieved through increased displacement, forced induction, robust internal components, and advanced technology. The power differences enable RS models to deliver an intense, high-revving driving experience on par with exotic supercars.

Unraveling Performance Characteristics
