Which Audis Have a V10? R8, S6, S8 and RS 6 Explained
Automotive Research, ASE Master Technicians & Fact-Checking
Direct Technical Summary
Audi put V10 engines in four legendary cars: the R8 supercar, S6, S8, and twin-turbo RS 6. Compare 5.2L V10 specs, horsepower output, and model years.
Audi put V10 engines in four main road-car families: the R8 supercar, C6-generation S6 sedan, D3-generation S8 sedan and C6-generation RS 6. The R8, S6 and S8 used naturally aspirated 5.2-liter V10s in different states of tune. The C6 RS 6 used a smaller 5.0-liter V10 with twin turbochargers.
These cars are all historical now. Audi ended R8 production in March 2024, and no new Audi road car currently uses a V10. If you are shopping used, the exact generation and market matter because the engines, layouts and U.S. availability are not the same.
Audi V10 models at a glance
| Audi family | V10 version | Induction | U.S. availability |
|---|---|---|---|
| R8 | 5.2-liter V10 | Naturally aspirated | Sold in the U.S.; V10 models arrived for the 2010 model year |
| C6 S6 | 5.2-liter V10 | Naturally aspirated | Sold in the U.S. for the C6 generation |
| D3 S8 | 5.2-liter V10 | Naturally aspirated | Sold in the U.S. for the D3 generation |
| C6 RS 6 | 5.0-liter V10 | Twin-turbocharged | Not officially sold new in the U.S. |
This is the useful short list. Later S6, S8 and RS 6 generations switched to other engines, so a familiar badge does not automatically mean the car has ten cylinders.
Does Audi still make a V10?
No. The R8 was Audi's last V10 road car, and production ended in March 2024. Audi says 45,949 R8s were produced across the model's two generations. Current S and RS models use other powertrains, so a new Audi dealer listing should not be described as a V10 unless it is an unsold older R8.
The end of R8 production also means that “which Audi has a V10?” is now a used-car and model-history question. A VIN, model year and engine code are more reliable than badges or an online listing title.
Audi R8 V10
The R8 is the Audi most closely associated with the V10. Its 5.2-liter engine sits behind the cabin in a mid-engine layout and drives through Audi's quattro system. The first-generation R8 initially appeared with a V8, then added the V10. The second generation centered the range on V10 power.
Outputs and trim names changed over time, including V10, V10 plus, V10 performance and rear-wheel-drive derivatives. That variation is why a buyer should verify the exact model year rather than treating every R8 V10 as mechanically identical.
The R8's appeal is also different from the sedan-based V10 Audis. It was designed as a low, two-seat sports car, not a luxury sedan that happened to receive an unusual engine.
C6 Audi S6 V10
The C6-generation S6 paired a naturally aspirated 5.2-liter V10 with a front-engine, all-wheel-drive luxury sedan. It is one of the easiest Audi V10s to overlook because later S6 generations returned to smaller turbocharged engines.
Do not identify one from an S6 badge alone. Confirm the C6 generation, model year and engine information. A newer S6 may be quicker in some circumstances, but it is not a V10 car.
D3 Audi S8 V10
The D3-generation S8 also used a naturally aspirated 5.2-liter V10, packaged in Audi's larger aluminum-bodied flagship sedan. Its mission was discreet high-speed luxury rather than the R8's sports-car experience.
As with the S6, the S8 badge spans several engine eras. Later S8s moved to turbocharged V8 power, so a generic “Audi S8 V10” search result needs a generation check before it can guide a purchase.
C6 Audi RS 6 V10
The C6 RS 6 is the outlier. Audi Sport gave it a 5.0-liter twin-turbo V10 rated at 580 PS and 650 Nm in official period material. It was offered as a sedan and Avant, but it was not officially sold new in the United States.
That makes U.S. examples unusual and potentially more complicated. Import status, federal eligibility, parts sourcing and service expertise should be verified independently before treating a listing like a normal U.S.-market Audi.
Are Audi V10s Lamborghini engines?
It is more accurate to say that Audi and Lamborghini V10s share Volkswagen Group engineering relationships than to call every Audi V10 a “Lamborghini engine.” The 5.2-liter R8 V10 and contemporary Lamborghini V10s are closely related, but vehicle-specific hardware, calibration, intake, exhaust, lubrication, installation and output can differ.
The S6 and S8 versions are not interchangeable with an R8 engine simply because displacement and cylinder count match. The C6 RS 6 is more distinct again: it uses a 5.0-liter twin-turbo V10 rather than the naturally aspirated 5.2-liter unit.
What to check before buying a used Audi V10
- Decode the VIN. Confirm model year, market and original engine specification before discussing price.
- Request complete service records. A stamped book alone is not enough; look for dated invoices and evidence of mileage-consistent work.
- Arrange a specialist pre-purchase inspection. The shop should know the exact R8, C6 or D3 platform rather than only general Audi maintenance.
- Inspect the car from cold. A seller-warmed engine can hide starting behavior, smoke, warning lights or noises.
- Run a full diagnostic scan. Stored and pending faults can reveal more than a short dashboard check.
- Check cooling, oil leaks and fluids. Packaging is tight and deferred work can become labor-intensive.
- Assess the transmission, brakes and suspension. Wear items on heavy performance cars can materially change the true purchase cost.
- Document modifications. Software, exhaust, intake, suspension and wheel changes should be evaluated for legality, calibration and serviceability.
A low advertised price is not the same as a low-cost Audi V10. The best candidate is usually the one with verifiable history, an appropriate inspection and enough budget left for age-related work.
Frequently asked questions
Which Audi sedan has a V10?
The C6-generation S6 and D3-generation S8 used naturally aspirated 5.2-liter V10 engines. The C6 RS 6 sedan used a 5.0-liter twin-turbo V10 in markets where it was offered.
Did the Audi RS 6 ever have a V10?
Yes. The C6 RS 6 sold from 2008 to 2010 used a twin-turbo 5.0-liter V10. The current RS 6 does not use that engine.
Which Audi V10 was sold in the United States?
U.S. buyers received V10 versions of the R8, C6 S6 and D3 S8. The C6 RS 6 was not officially offered new in the U.S.
Is every Audi R8 a V10?
No. The first-generation R8 was also sold with a 4.2-liter V8. Check the model year and engine specification rather than assuming every R8 has ten cylinders.
