There is no defensible universal winner between a used Mercedes-Benz E 63 AMG and an Audi RS 6. Both names cover several generations, trims, body styles and markets, so the meaningful comparison is between two specific cars identified by model year, chassis generation, engine, equipment, mileage, condition and service history. The clearest published contrast is between Audi’s first-generation RS 6 and a US-market 2021 Mercedes-AMG E 63 S Sedan, but those cars are separated by almost two decades and should not be treated as direct rivals.
Start with the exact cars, not the badges
“E 63 AMG” and “RS 6” are family names rather than fixed specifications. An early RS 6 sedan, a later RS 6 Avant and a 2021 E 63 S Sedan differ in powertrain, transmission, body, safety equipment, suspension systems and market equipment. Even within one generation, the regular E 63 and E 63 S can have different outputs and hardware.

Before comparing advertisements, record these details for both candidates:
- Model year and generation: identify the chassis or internal model code and whether the car is pre-facelift or facelifted.
- Trim: distinguish an E 63 from an E 63 S and an RS 6 from a special-edition derivative such as the first-generation RS 6 plus.
- Market: US, European and other-market cars can have different power ratings, safety equipment, emissions hardware, speed limiters and body-style availability.
- Body style: confirm sedan or Avant/estate. The RS 6 began in both forms, while later availability depends on year and country.
- Individual condition: mileage, accident history, modifications, tire age, warning lights and documented servicing often matter more than a brochure specification.
If a seller cannot provide a VIN, build sheet or registration details that establish these points, postpone the performance comparison. A precise but mismatched specification is less useful than a cautious comparison of two correctly identified cars.

What the RS 6 name has covered
C5: the first RS 6 (2002–2004)
Audi’s official history records the first RS 6 debuting in 2002 as both a sedan and an Avant. Its 4.2-liter, 90-degree twin-turbocharged V8 produced 331 kW (450 PS) and drove through a standard five-speed Tiptronic automatic. Audi quotes 0–100 km/h (62.1 mph) in 4.7 seconds. The generation also introduced Dynamic Ride Control, a hydraulic system designed to counteract pitch and roll.
The later RS 6 plus, introduced near the end of C5 production in 2004, raised output to 353 kW (480 PS). Audi lists an electronically limited top speed of 280 km/h (174.0 mph). Those figures apply to the RS 6 plus specification, not automatically to every C5 car.
Four generations and changing design
Audi’s 20-year retrospective identifies four RS 6 generations. C5, C6 and C7 cars were generally more understated in appearance, whereas the C8 is visibly more distinct from an ordinary A6. Audi says the C8 RS 6 Avant shares only its roof, front doors and tailgate with the A6 Avant base model and is widened by eight centimetres (3.15 inches). That description is specific to the C8 Avant and should not be applied to every RS 6 sedan, Avant or earlier generation.

What the E 63 name has covered
The 2016-generation 4.0-liter V8 cars
Mercedes-AMG’s announcement for the generation introduced in 2016 describes the E 63 4MATIC+ and E 63 S 4MATIC+ with a 4.0-liter biturbo V8 and fully variable all-wheel drive. The announcement presented the all-wheel-drive system as a major change intended to combine traction with more adjustable handling. It does not mean every earlier E 63 AMG used the same engine or drivetrain, so an older candidate must be identified on its own terms.
The documented US-market 2021 E 63 S Sedan
Mercedes-Benz USA’s 2021 E-Class Sedan Quick Reference Guide lists the E 63 S Sedan at 603 hp and 627 lb-ft from a 4.0-liter V8 biturbo. It specifies a nine-speed AMG SPEEDSHIFT MCT transmission and AMG Performance 4MATIC+ all-wheel drive. The listed 0–60 mph time is 3.3 seconds, and the electronically limited top speed is 186 mph.
The same guide says Drift Mode can make the E 63 S Sedan 100% rear-wheel drive. That is a manufacturer-described feature of the specified US-market 2021 sedan; it is not evidence that every E 63, every market version or every model year has the same mode or output.
Published specifications: a useful baseline, not a direct shootout
| Item | First-generation Audi RS 6 (C5) | RS 6 plus (C5, 2004) | Mercedes-AMG E 63 S Sedan (US, 2021) |
|---|---|---|---|
| Body styles noted by the manufacturer | Sedan and Avant | Special C5 derivative; confirm the individual body style | Sedan |
| Engine | 4.2-liter 90-degree twin-turbo V8 | 4.2-liter V8 derivative | 4.0-liter V8 biturbo |
| Quoted output | 331 kW (450 PS) | 353 kW (480 PS) | 603 hp and 627 lb-ft |
| Transmission | Five-speed Tiptronic | Not stated separately in the cited Audi history | Nine-speed AMG SPEEDSHIFT MCT |
| All-wheel-drive information | Not specified in the cited history summary | Not specified in the cited history summary | AMG Performance 4MATIC+, fully variable in this generation |
| Acceleration figure | 0–100 km/h in 4.7 seconds | Not stated separately in the cited history | 0–60 mph in 3.3 seconds |
| Top-speed figure | Not stated in the cited history | 280 km/h (174.0 mph), electronically limited | 186 mph, electronically limited |
| Special chassis or drive feature | Dynamic Ride Control hydraulic pitch-and-roll compensation | Not stated separately | Drift Mode can select 100% rear-wheel drive |
The units and test conventions differ: Audi’s 4.7-second result is 0–100 km/h, while Mercedes-Benz’s 3.3-second result is 0–60 mph. The cars also come from different eras. Do not subtract the times and call the result a controlled performance ranking.

How to compare performance fairly
Use the same measurement convention
Convert neither figure casually. A 0–60 mph test ends at 96.6 km/h, while a 0–100 km/h test ends at 62.1 mph. Launch control procedures, tires, fuel, ambient temperature and instrument methods can also change an acceleration result. Use manufacturer figures as an indication of the car’s intended performance, then compare like-for-like model years if acceleration is decisive.
Separate power from the whole powertrain
Peak output does not describe the transmission, gearing, traction strategy or chassis. The C5 RS 6’s five-speed Tiptronic and hydraulic Dynamic Ride Control belong to an early-2000s package. The 2021 E 63 S combines a nine-speed MCT transmission, fully variable 4MATIC+ and a rear-drive Drift Mode. A buyer considering a much newer RS 6 should obtain that car’s own official specification rather than importing C5 numbers into the comparison.
Read special modes as equipment, not a guarantee
Drift Mode is a selectable operating mode, not a promise that a car is suitable for public-road sliding. Verify that the feature is present on the exact vehicle, understand its activation requirements and use it only where legal and safe. Likewise, Dynamic Ride Control identifies a type of chassis technology on the first RS 6; it does not establish the condition of a particular used system.
Body style and everyday usability
Sedan versus Avant or estate
The first RS 6 was sold as both a sedan and an Avant, giving buyers a choice between a traditional three-box shape and a load-friendly estate. Later RS 6 body-style availability varies by market and year. Check the registration documents and factory equipment for the candidate rather than assuming that an RS 6 badge means an Avant.

The cited 2021 E 63 specification is for a sedan. If the alternative is an E 63 wagon or estate, verify its engine output, transmission, dimensions, suspension and equipment independently. A wagon’s cargo opening and roofline may change how useful it is, but those practical benefits should be evaluated on the actual car, not inferred from the sedan guide.
Dimensions and visual distinction
Audi’s eight-centimetre widening statement applies to the C8 RS 6 Avant relative to the A6 Avant base model. It explains why that specific car looks and feels more substantial, but it is not a universal RS 6 dimension. Compare parking width, garage clearance, tire replacement access and turning space using the exact generation’s data.
A disciplined used-car comparison process
- Capture the identity. Photograph the VIN plate and registration, then record model year, chassis code, engine designation, transmission, body style, market and trim. Ask for the original build sheet when available.
- Match the specification. Confirm whether the car is an E 63 or E 63 S, an ordinary RS 6 or RS 6 plus, and whether advertised features such as 4MATIC+, Drift Mode or Dynamic Ride Control belong to that exact build.
- Verify the maintenance file. Look for dated invoices, scheduled services, fluid changes, brake and tire replacements, recall completion and records from qualified technicians. A stamped booklet without supporting invoices is less informative than a coherent file that identifies the work and mileage.
- Check the title and history. Investigate accident, flood, theft, import and ownership records. Confirm that mileage readings progress logically and that modifications are disclosed.
- Arrange a cold inspection. Ask the seller not to warm the engine before arrival. A specialist can inspect start-up behavior, leaks, warning messages, suspension response, cooling systems and underbody damage more effectively from a cold vehicle.
- Scan every control module. A professional diagnostic scan can reveal stored faults that are not visible on the dashboard. Request a written report and an explanation of whether each code is current, historic or related to a repaired issue.
- Road-test under controlled conditions. Check smooth starting, transmission engagement, steering, braking, ride, alignment, tire noise and the operation of comfort and performance modes. Do not test maximum speed or unsafe maneuvers on public roads.
- Price the findings. Obtain written estimates for immediate repairs, deferred maintenance and consumables. Negotiate from documented work rather than from a generic assumption that one badge is cheaper to own.
Inspection checklist for an E 63 or RS 6
Documents and equipment
- VIN, registration and market origin agree with the advertisement.
- Factory engine, transmission and drivetrain match the claimed model and trim.
- Service invoices show dates, mileage and the performing workshop.
- Recall or campaign work is documented where applicable.
- Software tuning, exhaust changes, suspension changes and wheel alterations are disclosed.
- Both keys, manuals and security equipment are present or priced into the offer.
Mechanical and chassis checks
- Inspect the engine bay and underbody for fluid leaks, impact damage and evidence of poor repairs.
- Check cooling components, hoses, belts, electrical connectors and battery condition.
- Measure tire tread and inspect for uneven wear that could indicate alignment or suspension problems.
- Check brake discs, pads, calipers and parking-brake operation; performance-car consumables can be expensive even when no fault is present.
- Listen for drivetrain vibration, wheel-bearing noise and clunks over varied surfaces.
- Confirm that ride-height, damping and drive-mode selections respond consistently without warning messages.
Cabin, electronics and safety
- Test climate control, screens, cameras, parking sensors, windows, seats, memory functions and heated equipment.
- Confirm that airbag, ABS, stability-control and powertrain warning lamps illuminate during the self-test and then go out.
- Check that the navigation, phone connection and driver-assistance systems operate as expected for that model year.
- Inspect seat bolsters, steering wheel, pedals and switches for wear consistent with the stated mileage.
Reliability and ownership cost: what can and cannot be concluded
The manufacturer material cited here does not provide comparative reliability rates, average repair bills, insurance costs or current used asking prices for E 63 and RS 6 cars. It would therefore be misleading to declare one badge more reliable or cheaper to maintain in every market.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Both cars are complex, high-output performance vehicles. The sensible ownership question is whether a particular example has been maintained correctly and whether you can fund specialist diagnosis, premium tires, brakes, fluids and age-related repairs. Ask a qualified Mercedes-AMG or Audi RS specialist to inspect the car and quote the work required. That recommendation is a buying precaution, not a claim that a specific component has a proven failure rate in all generations.

When comparing prices, record the country, currency, listing date, mileage, ownership history, accident status, options and condition. A low advertised price may reflect deferred maintenance, an import specification, a nonstandard modification or a title issue. Without those variables, a price comparison is not meaningful.
Which one fits different buying priorities?
You want the newest documented performance specification
The published 2021 US E 63 S Sedan figures provide a clear modern benchmark: 603 hp, 627 lb-ft, a 3.3-second 0–60 mph claim, 4MATIC+ and a 186-mph electronic limit. Choose this route only when the specific car’s market, trim and service history match those specifications. Do not use the 2021 numbers to describe earlier E 63 models.
You want RS 6 heritage or an estate body
The RS 6 offers a documented history stretching across four generations, beginning with the 2002 C5 sedan and Avant. An early car supplies a distinct 4.2-liter twin-turbo V8, five-speed Tiptronic and Dynamic Ride Control, while a later Avant may provide a more visibly specialized body. Decide first whether age, body style and generation identity matter more than having the newest equipment.

Choose the candidate with the clearer identity, stronger records, cleaner inspection and realistic reserve for maintenance. If one car has an attractive specification but incomplete history, treat the missing evidence as a purchase risk rather than assuming the badge protects you.
You are choosing on acceleration alone
Compare same-generation, same-market manufacturer figures using the same test convention, then verify tires, brakes, launch procedures and drivetrain condition. The C5 RS 6’s 4.7-second 0–100 km/h figure and the 2021 E 63 S’s 3.3-second 0–60 mph figure are useful historical data points, not a controlled head-to-head result.
Common comparison mistakes
- Treating the names as one model: generation and trim changes can be larger than the difference between two badges.
- Mixing sedan and Avant assumptions: body style affects practicality and availability; confirm the exact car.
- Comparing 0–60 mph with 0–100 km/h as if identical: the endpoints and test conditions differ.
- Using one market’s specification globally: the 603-hp E 63 S data is specifically for a US-market 2021 sedan.
- Assuming a special edition is representative: RS 6 plus output and speed do not describe every C5 RS 6.
- Ranking reliability without evidence: no universal failure-rate or repair-cost ranking is established here.
- Ignoring condition because the car is cheap: a pre-purchase inspection and documented repair estimates are more informative than a badge-based bargain claim.
Bottom line for a used buyer
Compare two VIN-specific cars, not “the E 63” against “the RS 6.” Audi’s first RS 6 was a 450-PS, 4.2-liter twin-turbo V8 sedan or Avant with a five-speed Tiptronic and a quoted 4.7-second 0–100 km/h time; the 2004 RS 6 plus raised output to 480 PS and had a 280-km/h electronic limit. Mercedes-Benz’s documented US-market 2021 E 63 S Sedan delivered 603 hp, 627 lb-ft, a nine-speed MCT, 4MATIC+, a 3.3-second 0–60 mph claim and an 186-mph electronic limit. Those specifications show how far the families evolved, not which used car is automatically better.
The better purchase is the example whose generation, trim and market are verified, whose records are complete, whose inspection reveals no unacceptable faults and whose running costs fit your budget. If either seller cannot establish those basics, keep shopping rather than trying to resolve the uncertainty with a model-name comparison.
