Audi has unveiled the RS5, marking a significant shift as the brand’s first high-performance plug-in hybrid (PHEV). This model effectively succeeds the RS4, though with a name change reflecting Audi’s now-abandoned plan to differentiate combustion and electric vehicles through odd/even numbering. The new RS5 will arrive this summer in both Avant estate and fastback saloon configurations, promising a more aggressive take on its mid-sized performance executive offering.
Hybrid Powertrain and Performance Gains
The core of the RS5 is a twin-turbocharged 2.9-liter V6 engine paired with a 22kWh battery pack and a 174bhp electric motor integrated into the gearbox. While the engine shares a displacement with its predecessor in the RS4, Audi has made substantial changes. These include adopting a modified Miller combustion cycle – which boosts efficiency by closing intake valves early – and upgrading to water-cooled, variable-geometry turbos for improved responsiveness.
The result is a combined output of 630bhp, a 166bhp increase over the previous RS4. This translates to a 0-62mph time of just 3.6 seconds, slightly faster than its predecessor, and a top speed of up to 177mph. Despite the Avant model weighing 2370kg, Audi claims the RS5 feels significantly more urgent in real-world driving, extending a two-car-length lead over the RS4 Competition in a rolling drag race within 2.5 seconds.
Addressing Past Issues and Future Compliance
Audi’s product manager, Markus Fink, asserts that the RS5 is “ready to attack,” blending sports car performance with everyday usability. The company has also directly addressed the understeer issues that plagued previous generations, aiming for a more balanced driving experience.
The powertrain modifications are also crucial for meeting upcoming Euro 7 emissions regulations, ensuring the RS5 remains compliant while delivering increased power and efficiency. The switch to a modified combustion cycle and higher fuel injector pressure demonstrates Audi’s commitment to performance without compromising environmental standards.
The RS5 represents a new era for Audi’s performance lineup, combining hybrid technology with the brand’s legacy of high-speed driving. The move to plug-in hybrid technology is a pragmatic step, balancing performance demands with tightening emissions standards and consumer expectations for efficiency.
