Engine Overview

The Audi RS Q3 8U is available with one engine variant at 116 hp.

RS Q3 · Petrol· 310 PS
2013 2018

The CTSA is the first 2.5 TFSI in an SUV body: 310 PS from the same cast-iron block as in the RS3 8P/TT RS 8J. Intake valve carbon build-up from direct injection from 40,000 km; regular walnut cleaning mandatory. Haldex all-wheel drive instead of permanent quattro — power distribution reacts more slowly than in the RS3. Oil changes every 10,000 km with 5W-30 Longlife; don't forget Haldex oil change every 30,000 km.
