While the Audi S5 may be packing quite a punch under its hood, the RS5 would leave it for dead on the blacktop.
Swiss tuning firm Sportec has developed a mild stage one upgrade for the S5 that produces some not so mild numbers to get the S5 that much closer to its more hardcore cousin.
Consisting of a free-flowing air filter and an ECU remap, the kit manages to squeeze out an impressive 97hp from the supercharged 3-liter V6, raising power figures to 425hp and 520Nm of torque.
All that trims the S5’s century sprint time to an RS5-rivalling 4.6-seconds. However, top speed remains electronically locked at 250km/h.
