We really want the Audi RS3 to come to the US market, and based on a report from Car and Driver, it doesn't sound like we'll be stuck waiting that long. The report claims the new compact rocket sedan will debut next year as a model year 2018 vehicle.
Beyond that date, C/D's report expands on some of the details we reported on in our RS3 Sedan report from February. It backs up the claim about a 2.5-liter, turbocharged five-cylinder, but instead of a 400-plus-horsepower engine, C/D's report says it'd be "close to" 400 hp. That power would come from a turbocharged, 2.5-liter five-banger that's distinct from the unit currently offered in the Euro-market RS3 Sportback and the last-generation TT RS (the new 2.5 would first debut in that car's replacement). The new powerplant would be paired with Audi's seven-speed S-Tronic.
According to C/D, all this powertrain goodness will allow the new RS3 to hit 60 in four seconds flat and run up to 174 miles per hour. If correct, that means Audi's newest high performer will be a tenth of a second faster to 60 and have an extra seven mph on the high end than the most potent Mercedes-Benz CLA45 AMG. And while the two-door BMW M2 isn't necessarily a direct competitor – because coupe – it's worth pointing out that the RS3 will be 0.2 seconds faster to 60 and have an extra 19 mph to its top speed.
While C/D's report cites a "highly reliable source" for its information, we've naturally reached out to Audi to confirm as much as possible.
