You see, the brand new 2015 Subaru WRX STI uses the same 2.5-liter boxer turbo engine as the older model, good for just over 300 horsepower. The old Audi S3 only had 272 hp, but the third-gen launched in 2013 has upped that figure to 300 hp.So the two are now evenly matched? Not really, as this next video from Auto Express will demonstrate. In a drag race on an empty piece of British runway, the Audi S3 Saloon/Sedan actually proved to be faster than its Japanese rival. These results comes as a shock, since the German car doesn't have the rally breeding and the same reputation for handling. What's more, the S3 is a little down on power and significantly down on torque.What's nice about the race Auto Express organized is that they're comparing apples with apples here. The Audi S3 is tested as a four-door saloon with a manual, even though the 3-door hatch with S tronic would have been much faster. So there you go: the coolest Subaru ever made is slower than your average Audi. What is the world coming to?
