Default What is the difference between RS4 and RS6...

I noticed they both have the same 4.2 Liter V8 but the only performance difference I saw was the RS4 is not twin turbo charged which take the 340 to 450 HP so would it actually be worth it to get an RS6 or should I just get the RS4 and twin turbo charge it?

Default The new RS4 is based off the A4 platform.. so one.. it's a smaller car..

two.. it utilizes the new FSI 4.2 and the power output is 420 hp and mid 300 torque... the RS6.. being based off the C5 A6 platform.. utilizes the 4.2 (not FSI) with twin hair dryers (turbos)... power output at 450hp and about the same as far as torque goes.

The new RS4 will not have much room for twin turbos... but it probabaly can be done... but considering the minimal clearance.. a supercharger would be the best bet... that is if they even make one for the new RS4 and that's years away.
