Watch: The RS3 Testing at the Nurburgring Share Comments The new A3 sedan looks the part, and the last RS3 was the business, so we’re excited to see how Audi manages this generation’s RS3. Early indications are good. This video, shot at the Nurburgring, shows a camouflaged A3 testing at the ‘ring with what sounds distinctly like an inline 5 under the hood. Audi’s 2.5-liter five-pot currently produces 394 hp and 354 lb-ft of torque in the RS Q3. That’s exactly what it makes in the 2020 RS3, so we’ll be excited to see if Audi can churn out any more power or–if recent generational improvements are any indication–more torque.
