Consumer Reviews for the Audi A3

Disappointed ☹️
Anthony , 02/06/2022
2022 Audi A3 Premium 4dr Sedan w/40 TFSI (2.0L 4cyl Turbo gas/electric mild hybrid 7AM)
I am so impressed with the new A3, it’s quick, it handles great, and it has great luxury. You get a car that has all wheel drive and gets amazing gas mileage on regular fuel with the hybrid system. To me it’s the perfect car.
UPDATE: Luxury, great gas mileage, with a sporty feel makes this an excellent choice.
UPDATE: I have owned my 2022 A3 for 3 years now and the car is just as good … as it was brand new!
After owning the car for over three and half years I started having electrical problems and suspension problems. I ended up selling this car and bought a brand new Honda Civic Hybrid Sport Hatchback.
