The short answer: Audi S5 models have evolved from a 4.2-liter naturally aspirated V8 in early versions to a modern 3.0-liter turbocharged V6 with mild-hybrid technology in the latest ones.
Engine options by generation
These are the major engines that have powered the S5 across its generations, with indicative outputs for context.
- B8 (2007–2012): 4.2-liter FSI V8, naturally aspirated, roughly 354 horsepower and about 324–325 lb-ft of torque.
- B8.5 / 2013–2016 (and into 2017 in some markets): 3.0-liter TFSI V6 supercharged, about 333 horsepower and around 325 lb-ft of torque (torque figures vary by market).
- B9 / 2017–present: 3.0-liter TFSI V6 turbocharged with mild-hybrid system, about 349 horsepower and roughly 369 lb-ft of torque (approximately 500 Nm).
Across these generations, the S5 shifted from a high-revving naturally aspirated V8 to a more efficient turbocharged V6 with electrified assistance, preserving performance while improving efficiency.
Current-market nuances
In current-market S5 models, the 3.0-liter V6 turbo with mild-hybrid tech is standard in most regions, paired with quattro all-wheel drive. Some markets see slight variations in output due to emissions tuning and homologation requirements.
Summary
In sum, the Audi S5’s engine lineup has transitioned from a 4.2L V8 in earlier models to a modern 3.0L turbocharged V6 with mild-hybrid support in today’s versions. Expect roughly 333–349 horsepower and 325–369 lb-ft of torque depending on generation and market, with quattro all-wheel drive and an automatic transmission commonly featured.
Is an S3 or S5 faster?
It also comes standard with quattro all-wheel drive. In terms of performance, the S5 is the faster of the two models, with a 0-60 mph time of just 4.5 seconds. The S3, while still plenty fast, takes an extra 0.2 seconds to reach 60 mph.

What's faster, M340i or S5?
Power, torque and 0-62mph
That's 0.2sec quicker than the petrol version B9 S4, which is impressive given the S5 is just under 400kg heavier. BMW's M340i, by comparison, has near identical power and less torque but thanks to being almost 200kg lighter, gets to 62mph 0.1sec quicker, in 4.4sec.
