Aesthetically, the A3 sedan is thinner and has a larger 425L trunk (365 L on spPORTBACK vision). Inside, quality is flawless, as always, with Audi. Our test model was equipped with an automatic gearbox, a 7-speeded Stronic, which turned out to be very effective with steering wheel smoothly. Not being a great warrior, 1, 2 TFSI does well with acceleration, remaining flexible and responsive at low speeds.
