The A3 squares off best against the Mercedes-Benz CLA and the Acura ILX, which are sized about the same and both have rather more pedestrian roots.
Against those, the ILX gives the A3 a run for its money in terms of polish and value, while the CLA is more daring to look at but feels comparatively unrefined.
Buick's Verano comes in at a much lower price and equipment point than the A3, but the turbocharged model is a worthwhile consideration for those focused on value.
Meanwhile, BMW hasn't yet gotten in on the subcompact luxury sedan game, but its 2-Series coupe is more of a thoroughbred sports car compared to the A3.
