Audi's high-performance S models have forged a reputation in the US for offering wonderful driving dynamics in a package that doesn't scream, "I bought a sport sedan." However, its even higher-performance RS models are still somewhat of a rarity here. While the RS5 and RS7 are in the current US lineup, many of the wild RS models that Europe gets, like the RS6 Avant (pictured above), never make it to these shores. Unfortunately, that might not be changing anytime soon with the next-gen RS4.

The RS4 will follow the lead of the next BMW M3/M4 and (rumored) next Mercedes-Benz C-Class AMG and make the switch to a smaller turbocharged powerplant. According to an Audi insider speaking to Car and Driver, the next RS4 will drop the last generation's 4.2-liter V8 in favor of a turbocharged V6. The engine block will likely be shared with the supercharged 3.0-liter V6 in the regular S4 but fitted with two turbochargers. Power would likely be around 400 horsepower to match the 425-hp M3 and rumored 450-hp C-Class AMG.

Unfortunately, the RS might not make it across the pond to our waiting hands because the source says no decision has been made to export them yet. Obviously, we hope that Audi makes the right decision and brings the next RS4 here.

      I hope they come full circle back to turbo 5s.

        As a father of two under the age of 4, this would perk my "Dad" gauge as I am not an SUV/CUV buyer. My kids are already falling for wagons as the species is being killed off. It is really sad.

      Audi has lost their ways ever since they watered down the S4 to compete with the 335 and offered no RS4 in the US.... The 2.0T is just old and underpowered relative to the 4-banger offerings from others.......

        The S4 doesn't have the 2.0T, it has the supercharged 3.0 V6 in it. And those things scream. Even the A6 with that engine drives like a luxury muscle car.

          It's a 90* V6, it isn't a surprise the NVH is bad. Why do you think such engines are so rare now?

        Audi claims it 335hp...NO ONCE BELIEVES THEM...it's almost comical how much they under-rate that engine in the S4...almost as much as the 3.0T in the 335i which does NOT make just 300hp!

      Audi should have offered the RS6 and RS4 sedan here. They would have been more affordable and more popular than the RS7 and RS5. Not saying that the RS7 and RS5 shouldn't be here too. I'm just saying that there a market for all 4 in the US. Especially since the A6 and A4 are Audi's most popular models.

        There is a great resistance to spending $70K on relatively small performance hatchbacks in this country. I liked the S3 hatches I saw in Greece…but they're unobtainium in the US. Just not enough demand to justify the crash testing and emissions homologation.

      so they go back to their roots... fist generation RS4 was powered by a 2.7l twin turbo V6. Never understood that they went "small" displacement high reving V8 ´s in their heavy cars... the 4.2 V8 lack the punsh of large displacment V8 like the C63 AMG or almost any US V8 and they dont have the low rev punch of tubo powered V6. This 4.2l V8 fits to light sportcars but not heavy saloon and wagons

      If you give me a 6 speed avant quattro in this country I'll buy it with any engine.

      I hope the S4 goes TT as well. The current engine is nice, but having driven the 3.0'T' and a modified old 2.7T of roughly equal power, I just personally preferred the latter.

        The difference between equal torque and hp supercharged vs turbocharged engines is generally the jerk….x triple dot…first derivative of acceleration. The turbos seem to increase acceleration faster and harder than the superchargers (which just ARE) and give the illusion of faster acceleration when it's just jerk. All things being equal, the supercharger is faster. Area under the curve and all that stuff.

      Interesting that this V6 might be 3.0 at 400hp while Porsche Macan S has lots less with 3.0V6 TT but Macan Turbo has 400hp with 3.6L. Frankly, it would make more sense to fit a larger supercharger/intercooler to make 400hp and XXX torques. Twin turbos have 2X as many problems...

      The current RS4 is a wagon, as was the last gen. I don't see that changing, and since the wagon A4 is no longer sold here (well, it kind of is right now, but that remains to be seen for the next gen car), chances of it coming here are slim.

      The standard 4.0t has over 400hp and about 420 ft lbs of torque. Why create a new engine or swap the supercharger for twin turbos from the 3.0t in the S4 or S5?

      I will just get a B7 RS4 for $35k thanks. Best handling RS Audi of all time. The later ones lost a little bit of that magic. I will use the money saved to supercharge it by APR and give it 600hp. Thanks
