2021 Audi RS5 Coupe impresses in acceleration test without launch control

We all know the Audi RS5 is quick off the line given the 3.9-second sprint time mentioned in the official specs sheet for the 0 to 62 mph (100 km/h) run. But it’s a known fact the Four Rings typically (and deliberately) underestimate the capabilities of their performance cars from the Audi Sport division. Such is the case with the latest generation of the RS5 Coupe as revealed by the boss of R&D back in July 2017.

Speaking with Car Advice, Stephan Reil said that while the RS5 Coupe does the sprint in 3.9 seconds per the manufacturer’s claims, that time is applicable only “under the worst conditions.” He went on to say “you will not find a 4.0” and that the car is capable of completing the task in just 3.7 provided the conditions are ideal.

Motor put those numbers to the test by taking the facelifted RS5 Coupe to a drag strip for a total of four acceleration tests. None of them involved the launch control since in the first run it was turned off while in the second test it did not work for some reason. After that, an oil overfill message appeared on the dash, preventing the launch control to kick in for the remaining two attempts.

The first run was not exactly perfect, with the sprint completed in 4.2 seconds or three-tenths of a second more than what’s written in the technical specifications document. The Audi RS5 Coupe went on to complete the quarter mile in 12.3 seconds at 186.3 km/h (115.7 mph) based on the Racelogic vbox installed inside the car.

It was a lot better during the second acceleration test as the sprint took 3.8 seconds and the quarter mile was completed in 12 seconds flat at 186.6 km/h (115.9 mph). Ingolstadt’s speedy coupe was put through its paces a third time, but it was a tad slower, needing an extra tenth of a second to reach 62 mph (100 km/h) compared to the previous run.

The fourth and final attempt was different as it involved a one-foot (30-centimeter) rollout. As you can imagine, the performance numbers were substantially improved and the BMW M4 Coupe competitor achieved the sprint in just 3.6 seconds while the quarter mile.

To round off the evaluations, Motor tested the stopping power of the RS5 Coupe and its optional carbon-ceramic brakes. It came to a complete halt from 62 mph (100 km/h) in 36.8 meters (120.7 feet), which isn’t exceptional for expensive carbon-ceramic brakes, but the tires likely played a big factor. A better rubber would’ve allowed the car to come to a full stop sooner.
