The Audi RS4 is one of the most iconic high-performance wagons and sedans in history. Since its debut in 1999, the RS4 has evolved across five generations, each bringing more power, advanced technology, and enhanced performance.
But which RS4 generation is the best? From the high-revving V6 twin-turbo B5 to the roaring V8-powered B7 and B8, and the modern turbocharged B9, we’ll break down each RS4 to determine which one truly stands out.
B5 RS4 (1999-2001)
The B5 RS4 Avant was the first RS4 ever made, featuring a 2.7L twin-turbo V6 (derived from the B5 S4) but significantly upgraded by Cosworth to produce 375 hp. This car redefined what a fast estate could be, with Quattro AWD, a 6-speed manual, and a timeless design.
Pros:
- Twin-turbo power – Easily tunable to 500+ hp.
- Classic Audi styling – Aggressive yet subtle.
- Lightweight compared to newer RS4s.
Cons:
- Turbo lag – Not as instant as later naturally aspirated models.
- Expensive maintenance – Old engine, hard-to-find parts.
The one for collectors and tuning enthusiasts looking for a classic turbocharged Audi experience.
B7 RS4 (2006-2008)
The B7 RS4 is often regarded as the greatest RS4 ever made. It featured a 4.2L naturally aspirated V8 (BNS engine) producing 420 hp at 8,250 RPM, paired with a 6-speed manual and Quattro AWD. Unlike the B5, it was available as a sedan, Avant, and convertible.
Pros:
- One of the best naturally aspirated V8s ever – High-revving and sounds incredible.
- Manual transmission – The last RS4 to offer a manual gearbox.
- Balanced chassis – DRC suspension for improved handling.
Cons:
- Carbon buildup issues – The direct injection V8 requires frequent cleaning.
- High maintenance costs – Expensive repairs and oil consumption.
Perfect RS4 for purists and driving enthusiasts who want a naturally aspirated, manual V8 experience.
B8 RS4 (2012-2015)
The B8 RS4 continued with the 4.2L V8, producing 450 hp, but it was only available as an Avant (wagon). Audi also replaced the manual with a 7-speed S-Tronic dual-clutch transmission (DCT), making it quicker but less engaging than the B7.
Pros:
- Fast & refined – DCT makes shifting lightning-quick.
- Last naturally aspirated RS4 – No turbo lag, linear power delivery.
- Modern interior – High-quality materials and tech upgrades.
Cons:
- No manual option – Less driver involvement than the B7.
- Lack of tuning potential – The NA V8 doesn’t gain much power with mods.
For drivers who want a high-revving V8 but with modern tech and daily usability.
B9 RS4 (2017-Present)
The latest B9 RS4 switched to a 2.9L twin-turbo V6, producing 450 hp and 600 Nm of torque, making it the torque king of all RS4s. It also introduced mild hybrid tech, an 8-speed automatic gearbox, and a modern Audi Virtual Cockpit interior.
Pros:
- Faster than any previous RS4 – 0-60 mph in 3.7 seconds.
- Massive tuning potential – Simple remap pushes 500+ hp.
- Fuel efficiency & daily usability – Turbo V6 is more economical.
Cons:
- Less character than the V8s – Turbocharged, so lacks the high-revving drama.
- Heavier than previous RS4s – More luxury-focused than raw.
An RS4 for someone looking for the fastest, most advanced, and daily-drivable RS4 ever made.
Which Audi RS4 is the Best?
Each RS4 generation has its own appeal, but if we had to rank them based on performance, driving experience, and desirability, here’s how they compare:
Category | Winner | Why? |
Best Overall RS4 | B7 RS4 | High-revving V8, manual, engaging drive. |
Best for Collectors | B5 RS4 | First RS4 ever made, rare and iconic. |
Best Daily Driver | B9 RS4 | Fast, efficient, modern tech. |
Best Sound | B7/B8 RS4 | With a high revving German V8 exhaust note. |
Best for Tuning | B5/B9 RS4 | Twin-turbo engines with huge power potential. |
While the B9 is the fastest, and the B5 is the rarest, the B7 RS4 is widely regarded as the best due to its naturally aspirated V8, manual gearbox, and raw driving feel.
However, if you prefer a modern high-performance wagon with big tuning potential, the B9 RS4 is the way to go.
