S3 is a performance car that can stimulate people’s desire to drive. When you sit in it, it feels lower than the ordinary A3 chassis. The steering wheel feels particularly good, and it feels particularly at ease to hold, especially in sports mode, when the steering wheel sinks. The field of view is low and there is a desire for drag racing. The feeling of pushing the back is still strong, the body shakes slightly when it rushes forward violently, and the line of sight is kept on the road ahead but you can see the crazy beating tachometer, and the charming exhaust sound can be heard when the gearbox is shifted.
