Audi S7 Sportback: C7 and C8 generations, engines, and buying advice
The Audi S7 Sportback is the sporty variant of the A7, boasting a powerful engine and quattro all-wheel drive. Two generations have been produced since 2012: the C7 (2012–2018) with a 4.0 TFSI V8, and the C8 (from 2019) with more modern engines and technologies. We'll explore their differences and buying advice.
The S7 in brief
The S7 Sportback is a five-door coupe-style car that combines luxury, sporty driving, and practicality. It features a large boot with a tailgate, and its appearance is sportier than the A7.
Compared to the RS7, the S7 is more sedate and less demanding in terms of maintenance, while compared to the A7, it's more powerful and has a sportier ride.
Which one to choose
The C7 (2012–2018) comes with a 4.0 TFSI V8 engine producing around 420 hp, and since the 2014 update, around 450 hp. It's a famous, powerful car that's now more affordable, but its mechanics require careful maintenance.
The C8 (from 2019) features a new platform, a digital cockpit, a mild hybrid system, and a 48V setup. In Europe, it was offered with a 3.0 TDI diesel (around 350 hp), and in other markets, a 2.9 TFSI V6 petrol (around 450 hp).
If your budget is tight and you love the V8 sound, the C7 is an appealing choice. If cutting-edge technology is important, go for the C8.
Engines and transmissions
C7: 4.0-litre V8 twin-turbo TFSI, 7-speed S tronic gearbox, quattro drive. The engine has a cylinder deactivation function to reduce fuel consumption during light driving.
C8: 3.0-litre TDI V6 (mild hybrid) or 2.9-litre TFSI V6 (market-dependent), 8-speed Tiptronic automatic gearbox and quattro. Some models offer pneumatic suspension and a sporty rear differential.
What to check when buying a used S7
C7: check the turbocharger and oil leaks, as well as whether the engine runs smoothly and without vibrations when some cylinders are deactivated. Ask for the full service history.
Test the S tronic or Tiptronic gearbox, and the pneumatic suspension (if fitted) — it should raise and lower the car smoothly. Suspension repairs are expensive.
C8: check all screens, multimedia and assistance systems, as there are many. Also, check for errors in the mild hybrid system and whether the software has been updated.
