The Best Audi RS4 Generation
Mod Central
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.
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.
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.
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.
