• 2015 Audi RS3 losing the 2.5 liter TFSI turbo inline-5 engine in favor of an EA888 2.0 liter four-cylinder? Next generation Audi RS3 spotted testing

      AudiBoost likes Audi's 2.5 liter turbo inline-5 engine. A lot. As do a lot of people in the world with it winning four straight International Engine of the Year Awards. Not only is it a great motor in stock form it responds very well to tuning showing over 600 horsepower at the wheels with turbo upgrades on the stock engine internals. Audi themselves likes the motor and stated back in 2012 they would up the output in response to AMG's M133 four-cylinder.

      Since that report in 2012 Volkswagen stole away the man responsible for the AMG M133 engine. Volkswagen also stated they intend to beat AMG in the four-cylinder horsepower war. They are prepping a high output 2.0 liter EA888 based four-cylinder engine and previewed this motor recently in the Rolf R 400 Concept.

      So, that brings us to the next generation Audi RS3. You can see the car testing below but what is under the hood? Is it the 2.5 TFSI? If so, it would need to have over 400 horsepower (which it is easily capable of) in order to distance itself from this new upcoming 375-400 horsepower 2.0 liter four-cylinder. The other option is that it does not have the 2.5 inline-5 at all and instead has said four-cylinder motor.

      Which is it? The Germans are reporting that it is the 2.0 liter motor. The Brits over at CAR say it is the 2.5 TFSI inline-5. Everyone is simply guessing at this point and only those in charge at Audi know for certain.

      If AudiBoost were to guess chances are it is the four-cylinder engine. Why? Because the RS3 will go up against the CLA45 AMG. Volkswagen and Audi both want to make it clear they have the strongest four-cylinder motor. Audi is helping develop the engine and intends to use it and this is the best candidate for that motor.

      If that is the case, what happens to the inline-5? Does it go away? Perhaps for the RS3 but it also could go into a next generation TT-RS at over 450 horsepower. That certainly makes a lot of sense as an RS3 and a Golf R 400 could share the updated EA888 2.0 liter and as the Golf and A3 mirror each other anyway.

      It certainly would be sad to see the 2.5 TFSI motor go. Additionally, the RS3 sedan would be much more appealing with the 2.5 inline-5 than with the 2.0 inline-4 from a tuning and performance perspective no matter how impressive the four-cylinder is in stock form. We will just have to wait and see what happens.

        VW/Audi is playing catch up at this point they even went as far as throwing a boat load of money to get the guy from AMG. They were blind sided by the m133 and even commented themselves saying this. By the time this is tested and released well probably see a face lifted CLA 45 S with more power AMG won't stand around and have the advantage of being first.

        on another note my brother has the Cla 45 what a pocket rocket ! The way they tuned it stock was to keep the torque curve flat by bleeding boost down low and building up as revs went up and the car had great top end but lacked mid range punch. Rebellion tune should solve that we'll be installing it next week it's the newest V2 box I got one of the first batch. Supposedly boost output to 415hp and 400 pound feet of torque and a test car hit 0-100 in 8.7 ! Wonder what It will do FBO and once they figure out E85 support

        I don't think I've heard of this box or tuner yet. I'm going to look this up.

        AMG said they could up the output but that would alienate the first year customers.

        I don't know if Audi is playing catch up as the 2.5 TFSI is more than capable of handling the M133 and then some.

        Rebellion is huge in the 45 scene I would consider them the leaders in that market for the consumer. Obviously renntech is great as well but $2500 for a piggyback really? They are also testing a new tcu tune out that will cut shifts time considerably and lower torque limiters built into the drivetrain.

        O yea they are ! Were talking about in the 4 cylinder game AMG could've went 5, 6, 8 etc but this is going to be a new trend in the tree hugger car industry going forward. They completely blind sided audi the M133 even makes more power than the TT-RS 5 cylinder stock ! It makes more then a K04 upgraded tfsi 2.0 FBO with HPFP Dp race fuel (Stage 2+) If they weren't playing catch up they wouldn't be so desperate as to take AMG's engineer. If they were doing so good they'd be fine with their own guys right? Why take someone from an inferior company designing inferior motors

        You definitely make a good point about the engineer and I'm surprised more sites don't point this out as often as I do.

        It's true ! AMG will recover just fine they build from within and like to let their guys earn there stripes instead of just throwing money around like VAG. Good thing just throwing money around doesn't always work or the Yankees would win the World Series every year. Imitation is the sincerest form of flattery !

        honestly this is the first and only place I heard about this the other mb forum is good for nothing except how much carbon fiber people can put on there cars and look like total asses #becausenotracecar

        I knew AMG wouldnt just stand around and let audi take the crown & that the new guy Tobias is a little nutty haha heres his answer to a similar question ..

        Moers also hinted that there was more to come from the Mercedes A45 AMG’s 355bhp 2.0-litre turbocharged four-cylinder engine: “Yes it’s possible [to extract more power], not tomorrow, but everyone is working on technology like this.”


        When we asked whether he would be able to beat the 414bhp output of Audi’s recent 2.0 TSI TT sport Quattro concept, Moers replied: “I think Audi are strong, but we are AMG.”

        Really hope they don't ditch the 5...it's such an amazing engine and I love the way it sounds.

        I hope they don't ditch it either but I'm trying to figure out how they can resolve having a 400 horsepower four-cylinder and a 370 horsepower inline-5. It seems the only choice is for the RS3 to have the new four.
