2019 Audi RS3 Vs 2017 RS3: Have The Stricter Emission Standards Affected Performance?

As emissions regulations become more strict, it could seem as though performance cars, especially those in Europe, aren’t as powerful as they were. At a recent evaluation aimed at seeing if that holds true, CarWow matched a 2017 Audi RS3 from the most recent 2019 RS3.

On paper, the accession to the 2019 RS3 doesn’t even appear to reduce electricity, as just like the 2017 model, its own 2.5-liter five-cylinder turbocharged engine pumps the exact exact figures: 400 hp and also 354 lb-ft (480 Nm) of torque.

The 2019 model has more torque while the car includes a fall off after attaining peak torque in power.
