Its **interchangeable compatibility** with the **Audi 3.0T V8 (R079N) and 4.0L Twin-Turbo V8 (R079N)** engines common in the **S6 (C7), S7 (4K), and A8 (D2) L **ensures seamless integration with aftermarket components like **crankshafts, pistons, and bearings** from reputable manufacturers such as **Mahle, JE, or Scat**. Unlike mass-produced aftermarket rods, this **OEM-specification part** maintains the **original Audi engineering tolerances**, including **0.002" 0.003" wall thickness consistency** and **precise big-end bearing journal fit**, which is crucial for maintaining optimal engine efficiency and longevity. Whether used in a **restoration project, a high-performance rebuild, or as a direct replacement for a failed rod**, this component represents the pinnacle of **German engineering precision**, ensuring reliable performance under the most demanding conditions from daily driving to track-focused applications. For enthusiasts seeking **uncompromising quality and compatibility**, the **Audi R079N 4.0L Connecting Rod (079BK)** stands as an indispensable part for preserving the integrity and power potential of one of Audi s most legendary V8 engines.

### Pros and Cons of Buying an Audi R079N (A8, S6, S7, 4.0L V8, Connecting Rod 079BK) from 2016 2018

---

#### **Pros**

1. **Performance and Power**

The 4.0L V8 (W12 in the S6/S7) is a legendary engine, producing **435 510 hp** (depending on model) and **429 500 lb-ft of torque**. The R079N chassis is a high-performance platform with a **double-wishbone suspension**, **adaptive damping**, and **quattro all-wheel drive**, making it a capable grand tourer or track car. The S6/S7 s V12 (if considering) is even more exhilarating, but the V8 remains a strong contender.

2. **Luxury and Comfort**

Audi s interior is known for its **premium materials**, **high-quality craftsmanship**, and **advanced tech** (virtual cockpit, MMI navigation, ambient lighting). The **S6/S7** offers a more spacious and refined cabin than the A8, while the **A8** provides a more traditional luxury experience. The **R079N** (especially the S6/S7) strikes a balance between sportiness and comfort.

3. **Reliability (Compared to Other Audi V8s)**

The **4.0L V8 (W12 in S6/S7)** is more robust than earlier Audi V8s (e.g., 3.0L from the S6/S8 of the 2000s) and avoids some of the common issues of the **3.0TFSI** (turbocharged) engines. However, **timing chain stretch** and **oil consumption** can still be concerns if maintenance is neglected. The **R079N** is generally more reliable than its predecessors, but it s not bulletproof.

4. **Aftermarket Support and Tuning Potential**

The **4.0L V8** has a strong aftermarket, with options for **ECU tuning (MHD, JB4, etc.)**, **intake/exhaust upgrades**, and **suspension modifications**. The **S6/S7** benefits from **Audi Sport Quattro** packages, while the **A8** can be transformed into a **high-performance GT** with proper modifications.

5. **Resale Value (Compared to Some Peers)**

While not as high as a Porsche 911 or BMW M5, the **R079N** holds its value reasonably well, especially the **S6/S7**. The **A8** resale is more modest but still decent for a luxury sedan. The **V12 models** (S6/S7) command a premium, but the **V8 versions** are more accessible.

6. **Driving Dynamics**

The **R079N** is one of Audi s most **engaging luxury cars**, with **sharp steering**, **precise handling**, and **excellent braking** (especially with the **S6/S7 s carbon-ceramic brakes**). The **A8** is more of a **comfort cruiser**, but the **S6/S7** is a **true grand tourer** that can handle both **highway speeds and track days**.

7. **AWD and Off-Road Capability**

The **quattro system** is one of the best in the business, providing **exceptional traction** in all conditions. The **S6/S7** can be equipped with **Audi Sport Quattro** packages, improving off-road performance.

8. **Aesthetic Appeal**

The **R079N** has a **distinctive, aggressive stance** (especially the **S6/S7**), with **LED lighting**, **aerodynamic enhancements**, and a **sporty front grille**. The **A8** is more understated but still elegant.

---

#### **Cons**

1. **Maintenance Costs**

Audi s **premium parts and labor** make ownership expensive. The **4.0L V8** requires **regular oil changes (every 5,000 7,500 miles)**, **timing chain inspection**, and **potential fuel system upgrades** (if running high octane). **Transmission servicing** (if automatic) can also be costly.

2. **Timing Chain and Oil Consumption Issues**

Some **4.0L V8s** (especially in high-mileage examples) suffer from **timing chain stretch**, leading to **ticking noises** and **potential engine damage** if ignored. **Oil consumption** can also be an issue, requiring **frequent top-ups**. The **S6/S7 V12** is more prone to these problems than the V8.

3. **Electrical Gremlins**

Audi s **complex electronics** (infotainment, sensors, lighting) can be finicky. **Software glitches**, **sensor failures**, and **infotainment lag** are common complaints. Some owners report **random warning lights** that require **dealer visits**.

4. **Fuel Economy**

The **4.0L V8** is **not fuel-efficient**, averaging **15 18 MPG combined** (worse in the S6/S7). High fuel costs can add up, especially for daily driving.

5. **Comfort vs. Sport Balance (A8 vs. S6/S7)**

- The **A8** is **softer and more sedate**, with a **less engaging drive** compared to the **S6/S7**.

- The **S6/S7** is **more engaging but still not a track weapon** it s a **luxury performance car**, not a **high-performance sports sedan** like a BMW M5 or Mercedes AMG E63.

6. **Depreciation**

While better than some luxury cars, the **R079N** still loses value over time. The **V12 models** hold value better than the **V8**, but neither is a great long-term investment.

7. **Weight and Handling Limitations**

The **R079N** is **heavy** (especially the **S6/S7**), which can make it **less nimble** than lighter competitors (e.g., BMW M5, Porsche Panamera). While **quattro helps**, it s not as **responsive as a rear-wheel-drive sports sedan**.

8. **Common Issues to Watch For**

- **Transmission (if automatic)**: Some owners report **rough shifting** or **electrical issues**.

- **Exhaust Manifold Cracks**: The **4.0L V8** can develop **cracks in the exhaust manifolds**, leading to **leaks and performance loss**.

- **Water Pump Failures**: The **cooling system** can be problematic, requiring **regular checks**.

- **Infotainment Lag**: The **MMI system** can be slow and unresponsive.

9. **High Purchase Price**

Even used examples (especially **low-mileage or well-maintained ones**) can be **expensive**. A **2016 2018 S6/S7 V8** can easily cost **$50,000 $80,000**, while an **A8 V8** might be **$40,000 $60,000**.

10. **Dealer Dependency**

Many **Audi-specific repairs** require **factory training**, making **independent mechanics less reliable** for complex issues.

---

### **Ending Conclusion**

The **Audi R079N (A8, S6, S7, 4.0L V8)** is a **fantastic choice** if you want a **luxury performance car** that balances **comfort, power, and driving enjoyment**. It s **more reliable than older Audi V8s** but still requires **proactive maintenance** to avoid costly repairs. The **S6/S7** is the **better overall package** more engaging, more capable, and more desirable while the **A8** is a **softer, more traditional luxury sedan**.

If you **prioritize performance, handling, and Audi s quirks**, the **S6/S7 V8** is the **best pick**. If you want **more luxury with slightly less sportiness**, the **A8 V8** is a **solid alternative**. However, if you re looking for **a daily driver**, consider whether the **maintenance costs and fuel expenses** are justified.

For **track use or enthusiast ownership**, the **R079N is excellent**, but for **strictly daily use**, a **less expensive but equally capable car** (e.g., BMW M5, Porsche Panamera, Genesis G80) might be a better value.

---

### **Recommendation**

You **prioritize driving dynamics** over pure luxury.

You **plan to maintain it properly** (oil changes, timing chain checks, fuel system upgrades).

You **want a capable all-weather AWD car** that can handle both **highway cruising and track days**.

You **enjoy Audi s tech and styling** and don t mind **electrical quirks**.
