No. The 2015 Audi A6 did not use a supercharged engine; it relied on turbocharged powertrains.
Across the 2015 A6 lineup, engines are turbocharged, with four- and six-cylinder options (and a diesel variant in many markets). The Audi S4, a separate model in the lineup, used a different setup that has included a supercharged 3.0-liter V6, but that configuration does not apply to the A6 family from that year.
Engine options in the 2015 A6
The following list outlines the typical powerplants available for the 2015 A6 in most markets.
- 2.0-liter TFSI turbocharged four-cylinder
- 3.0-liter TFSI turbocharged V6
- 3.0-liter TDI turbocharged diesel
Conclusion: None of the standard A6 engines for 2015 employed a traditional supercharger; all were turbocharged. Buyers seeking a supercharged Audi from that era would look to the S4 rather than the A6.
Turbocharging vs. supercharging: a quick explainer
Turbocharging uses exhaust-driven turbines to compress intake air, often boosting efficiency and peak power at higher engine speeds. Supercharging uses belt-driven compressors connected to the engine, delivering immediate boost across the rev range but typically at a cost to efficiency. In Audi’s lineup around 2015, the A6 relied on turbocharged engines, while some other models and generations (notably the S4 in earlier years) used a supercharged setup.
Summary
In short, the 2015 Audi A6 is not a supercharged model. Its power came from turbocharged engines (2.0T, 3.0T, and TDI), with a supercharged configuration found in other Audi models of the era. If you’re evaluating a used 2015 A6, verify the specific engine to understand its turbocharged performance characteristics.
