Audi's working on world’s most powerful four-pot to motivate new model.
Audi is working on a new model to fill the gap that will soon exist between the Audi S3 and upcoming RS3. Dubbed the S3 Plus, power will come from a new EA888 four-cylinder turbo engine that Audi sources claim will have in the region of 375 hp and 369 lb-ft of torque. If true, that would make it the most powerful four-cylinder engine in the world, overtaking the 355-hp AMG unit that sits in the A45 and CLA 45 models.
Interestingly, that engine was developed by Friedrich Eichler, who VW Group poached from AMG last year to head-up its engine, transmission and hybrid development. His task is to deliver a new four-cylinder engine that will trump his own creation. As well as powering the S3 Plus, Audi plans for the upgraded EA888 to find home in a more potent version of the next-gen TT Coupe. The A3 lineup is currently topped by the 296-hp S3 and given the numbers revealed about the S3 Plus, it's fair to assume the RS3’s reworked 2.5-liter five-pot will have well beyond 400 hp. That car is expected to debut in March at Geneva, while the S3 Plus could be revealed by the end of the year.
