Audi has just facelifted its A3 and S3 models, but the most interesting addition to the lineup will be the RS3 sedan. We now hear from a highly reliable source within the company that the RS3 sedan will come to the U.S. market in 2017 as a 2018 model.
The RS3 again will be powered by a 2.5-liter turbo five-cylinder?but it will be a completely new engine that shares virtually nothing with the current 2.5-liter five in the European-market RS3 Sportback and the last-generation TT RS.
The new single-turbo five-cylinder will debut at the Beijing auto show in the new TT RS; the RS3 will appear shortly thereafter. The engine’s power output will be close to 400 horsepower, enough to surpass the Mercedes-AMG CLA45 4MATIC, which is rated at 375 horsepower. The RS3 sedan will be fitted with a DQ500 seven-speed dual-clutch automatic; top speed will be governed at 155 mph or 174 mph, depending on market and options. We expect the sprint from zero to 60 mph will take four seconds flat.
