Audi A7 Sportback: C7 and C8 generations, engines and trims
Audi A7 Sportback — a large five-door coupe-style car, technically similar to the A6 but lower and more elegant. We look at both generations — C7 (2010–2018) and C8 (from 2018), their engines, trims and what to check before buying a used A7.
A7 in brief
The A7 is available in just one body style — Sportback: a four-door coupe silhouette with a massive rear hatch that opens with the rear window. This makes the boot spacious and practical to load, although there's less headroom for rear passengers than in the A6 saloon.
The model is praised for its looks, quiet cabin and powerful engines. Most come with V6 engines and quattro four-wheel drive, making the A7 quick, stable on the road and comfortable for long journeys. The sportiest versions are the S7 and RS7.
How C7 and C8 differ
The C7 generation (2010–2018) is currently the most accessible way to own an A7. Cars updated in 2014 received matrix LED headlights (often as an extra), a newer infotainment system and more efficient engines. Most C7s now have high mileage, so service history and condition are key.
The C8 generation (from 2018) is more modern and significantly more digital: the cabin features two touchscreen infotainment displays and a digital driver's display (Audi virtual cockpit), plenty of driver assistance systems, and engines with a mild hybrid system. Plug-in hybrids 50 TFSI e and 55 TFSI e have also been added.
If budget allows, many buyers are better off choosing the C8 — it's newer and comes with more kit. The C7 is ideal for those who want more car for less money and are prepared for higher maintenance costs.
Engines and gearboxes
The C7 is most commonly found with 3.0 TDI diesel V6 engines (around 204–326 hp, the most powerful with twin turbos) and a 3.0 TFSI petrol V6 with a mechanical supercharger (around 300–333 hp). The 2.8 FSI is rarer. The S7 had a 4.0 TFSI V8 (around 420–450 hp), while the RS7 had the same V8 but with around 560–605 hp.
On the C8, engine names indicate power levels: 40 TDI and 45 TFSI are 2.0-litre four-cylinders, 45 TDI and 50 TDI are 3.0-litre V6 diesels, and 55 TFSI is a 3.0-litre V6 petrol (340 hp). In Europe, the S7 was built with a 3.0 TDI V6 diesel (around 350 hp), and the RS7 with a 4.0 TFSI V8 (600 hp and more).
Gearboxes are automatic only: in the C7, front-wheel-drive models often have a stepless Multitronic, while others get a 7-speed S tronic or 8-speed Tiptronic. In the C8, V6 diesels are usually paired with an 8-speed Tiptronic, while other engines get a 7-speed S tronic.
What to check when buying a used A7
In 3.0 TDI engines, timing chains are at the back of the engine, so replacing them is expensive — a cold engine shouldn't rattle. On diesels, check the diesel particulate filter (DPF), EGR valve, and AdBlue system, and on petrol 3.0 TFSIs, look for coolant or oil leaks.
The automatic gearbox should shift smoothly and without judders. Pay particular attention to multitronic and S tronic boxes when pulling away and driving slowly — any hesitation or slippage could indicate an expensive repair. Ask if the gearbox oil has been changed on schedule.
If the car has air suspension, check that the body doesn't sag after overnight parking and that the compressor runs quietly. In a C8, ensure both screens, cameras, and assist systems work flawlessly, and diagnostics show no issues with the mild-hybrid system.

Frequently asked questions
How does the A7 differ from the A6?
The A7 is technically similar to the A6, but it has a lower coupe-style body and a large rear hatch that opens with the glass. The A6 is roomier at the back and often cheaper, while the A7 appeals to those who prioritise style.
Which A7 engine is best when buying used?
For many buyers, the 3.0 TDI V6 diesels are the most suitable — they're economical on long journeys and have plenty of pull. If you mostly drive in the city, consider a petrol engine, as the diesel particulate filter needs longer journeys.
Is the A7 suitable for a family?
Yes, if your family doesn't have very tall rear passengers: the boot is spacious, and the cabin is comfortable for long journeys. If you need more space at the back, the A6 Avant estate is a more practical choice.
Is it worth buying an A7 with air suspension?
Air suspension offers plenty of comfort, but its components wear over time. Choose a car whose body doesn't sag after standing, and whose compressor runs quietly, and ask about previous repairs.
