    RS4 / R8 engine power problems

    hey guys,

    according to comments on some other forums, most RS4 seem to deliver substantially less power than promised. (see link below) Sportec tested a dozen new RS4 and none of them had more than 400hp (most between 380-420). Apparently they are even building up a new RS4 with the old biturbo engine.! In fact also ABT offers a similar version.

    I know the sportauto test figures were excellent, but it would also be fair to assume that that specific car had all HPs for sure. So the Quattroruote figures seem to be more reflective of real life performance of the car (I know the 997tt was crap, but usually their measurments are good). and with a non turbo engine its not easy for a customer to get back to the promised power level just by boosting the pressure a bit.

    So this also worries me re the new R8 who will use the same engine (except dry sump). The test cars will have brilliant performance but customer cars ??

    would appreciate your thoughts/experience with RS4 engines.
    thanks and GO FERRARI this afernoon

    Re: RS4 / R8 engine power problems

    Problems were with early production run of RS4 engines(first 25 cars or so). Audi solved all problems. Regarding dyno tests... It is more akward to measured AWD power as we all know but, some people are ignorant. After around 10000km you have all the power you need on your RS4.

    Difference between RS4 and R8 engine are:
    -true dry sump(R8)
    -different intake system(R8)
    -different motronic(R8)
    -all R8 engines build by specially trained personal
    -different exhaust
    -sequential gearbox a la e.gear on R8(again different electronics)
    -completely differently biased ESP system

    More news shortly but, RS4 and R8 are two completely different car. They are not even remotly in the same class...

    Re: RS4 / R8 engine power problems

    thanks Kreso, let's hope for the best!

    still i find it disturbing that the rs4 engines do not get to 420 hp as declared...
