Downsizing engines and adding forced induction is the new wave in fuel economy engineering as companies strive to maintain performance levels and the latest reports indicate Audi is leaping into the ring with both feet, lopping two cylinders from its mighty RS4 sedan and replacing them with a supercharger. Enthusiasts may lament the loss of the extra pots, but purists will relish the return to six-cylinder forced induction.

The next-generation RS4 will reportedly feature a 3.0-liter supercharged V-6--the same basic unit found in the somewhat tamer S4, though it will no doubt be in higher tune in its RS application. The outgoing generation RS4 is powered by a 4.2-liter V-8 rated at 414 horsepower. Power figures for the new engine aren't yet known, but the new supercharged V-6 is expected to be thoroughly sporty.

Adding the requisite power bump in the next-generation RS4 model would place output on par with the V-8 model, and thanks to the supercharged induction, a very wide torque band would be available from an even lower RPM--all ingredients for very strong performance.

The original Audi RS4 featured a forced-induction V-6, though it was a twin-turbo unit generating 261 horsepower from its 2.6L displacement. Efficiency ratings of forced induction technologies have advanced somewhat since the first twin-turbo RS4 was built in late 1999 and the addition of twin-turbos or any dual-charging system to the current RS4 has been dismissed as prohibitively complex and expensive for the gains over a single supercharger design.

Whether Audi will actually follow through with the return to a forced-induction six-cylinder or not remains to be seen, but with impending fuel and emissions standards tightening around the world, even the high-performance luxury carmakers will have to change to keep fleet averages in line. No word yet on a release date but in the meantime, check out our latest computer-generated rendering which gives us an early look at the aggressive lines Audi’s designers have planned for the new RS4.

Incidentally, Audi is set to launch its RS5 based on the A5 Coupe early next year. This model will likely get a 450 horsepower version of the current RS4’s 4.2-liter V-8.

  1. While I like the idea because of the loss of weight, I doubt we will see the Avant version in America, just the sedan.

  2. One of my all time favourite cars is back. Shame that the V8 dont will be dropped, but i guess it just means that i may have to shop around for a 2nd hand version of the previous version. power, grace, poise, style and practicality, whats not to like about an RS4 avant

  3. A) I'm a huge fan of the latest RS4. The big V8 does it for me. A V6 (even supercharged) will not sound and perform the same way the V8 does now.
    B) I'm hoping for another RS4 sedan - not avant!

  4. Is it just me, or no one noticed the blatant error he did, 261 hp.... an rs4? no, thats the s4... the b5 RS4 made 375 hp... and its a 2.7L, you round up not down in motor sizes...

  5. The RS4 will retain a V8, not the V6T. The S4, A6 and later S5 will get the V6T. Everyone who knows a tiny bit about Audi knows this.
    Uh, yeah, the original (B5) RS4 (Avant only) had a 2661 cc (2.7 liter) twin turbo generating 380 HP. Please check your numbers.
    Real RS cars are Avants ONLY. Audi, please bring us the next RS4 ONLY in Avant form. ;-)

  6. Thanks for your nice article get to know lot's of information about RS4. and surely it will be a great one by Audi.

  7. Like I heard new RS4 will have the same V8 4.2 FSI (450 HP) "Maybe" with Super Charger unknown 100% yet. 2000 B5 RS4 had 380 HP with 2.7 V6 BiTurbo same as B5 S4 265 HP just S4 had smaller Turbos K03 not K04 like RS4 some other difrence like injectors, MAF, IC also brakes and else. Further Audi's will lose Lambo engines because of weight. Their future with Chargers and Turbos but also with same V8 engines and POWERFULL (bad word)- DIESEL engines. Hoping they will do something with weight center to avoid oversteering. Good luck driving AUDI
