    • Audi/VW to take most powerful production four-cylinder title from Mercedes AMG? Audi S3 Plus model with 375 horsepower EA888 2.0 liter coming?

      Mercedes has the most powerful production four-cylinder in world right now with their 2.0 liter AMG built and turbocharged M133 motor. Audi and Volkswagen may be gunning for that title with a high performance version of the EA888 2.0 liter direct injected and turbo four-cylinder. Audi already has 296 horsepower out of this same motor in the S3 model. Apparently an S3 Plus would slot in above this at 375 horsepower and then the RS3 would be positioned (likely at 400+) above that.

      How does VW plan to boost the output? The block, crank, and rods would all remain but the cylinder head would be changed and accompanied by a larger turbocharger. This makes the motor cheaper to build than the AMG M133. It also means the pistons would likely be changed probably to a lower compression set as Mercedes pushes 26 pounds of boost stock with a relatively low for a direct injection motor 8.6:1 compression ratio.

      The Audi RS3 would also have to be moved up in output a bit to distance itself from this new S3 especially if it has all wheel drive and a DSG transmission.

      So why is Audi/VW pushing the four-cylinders so hard? Well just about this time last year VW poached AMG's head of engine development who was responsible for the AMG 2.0 liter M133 motor. Now the task will be to outdo what he did for Mercedes with VW/Audi being the benefactors of his knowledge. If he succeeds, he is worth whatever they paid for him and then some.

        Wow...I've had my eyes on the rs3, it's a great looking car...

        This segment is heating up, only good things can happen as a result. Maybe the m2 will be a modified n20, it would fit in with this segment

        They'll have to redo the head on the n20 because it's prone to crack at around 300whp.

        I'm glad they're doing this cause it's making it very interesting for all other 4 bangers to really step up the game.

        Also if APR can achieve 450BHP on the older VW/Audi 2.0T with the stage 3+ kits. It can be very likely Audi/VW they'll do the same.

        What's going to happen with the S4, RS4, S5, RS5. The new S3 is already quicker 0-100km/h than the current S5...

        the race for high powered 2.0 4cyl is a bit tricky. Obviously at these engine sizes you're depending heavily on forced induction, so now you have to manage to make high power and keep the spool/lag relatively low.

        Sure guys who mod these cars don't mind full boost at 4-5K, but off the show room floor that's a tough thing to sell.

        Either way, I'm all for 400+bhp RS3.

        Well that's the trick, isn't it? Seeing who can do it best while offering a warranty and managing lag.

        They've all essentially capped themselves at 2.0 liters so they need to build a motor that can run on pump gas while still out-doing the other guy. It's a fun competition.

        Now for BMW to get in on it...
