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.
