Yes, reports are popping up from an Audi of America employee that the Audi RS3 would transition from its Euro-market Sportback body style to a more conventional four-door, and that its styling would be updated in the process. Oh, and it'll have a 400-plus-horsepower, 2.5-liter, five-cylinder turbo with which to bash the four-cylinder AMG. The report comes from Quattro World by way of CarScoops, and goes on to claim that Audi hallmarks like Quattro all-wheel drive and a seven-speed S-Tronic dual-clutch transmission will both be present.
The new RS3 Sedan would arrive on US shores in 2017 as a 2018 model, with prices starting between $55,000 and $60,000. That should make Mercedes-AMG very nervous – the CLA45 may start around $50,000, but getting it past the $60,000-range is simple (your author was driving a nearly $68,000 CLA45 just last month, for example).
Naturally, we have a call in with Audi of America to see if there's any credence to this report. Stay tuned for updates.
