Autocar's UK-based review of the Audi A3 focuses on its European-market variants, where the car is sold with both petrol and diesel engines. They describe the A3 as a beautifully built, refined hatchback (and saloon) that prioritizes comfort and quality over outright sportiness, unlike some rivals. The interior is lauded for its excellent material quality and build integrity, with a clean, minimalist design that includes the standard 10.1-inch MMI infotainment system. Autocar notes that the ride is composed and the cabin is exceptionally quiet, making long journeys effortless. However, they find the steering to be light and lacking in feedback compared to the BMW 1 Series, which is more engaging to drive. The 1.5-liter mild-hybrid petrol engine is smooth and efficient, though the 2.0 TDI diesel is the one for high-mileage drivers. Rear headroom is tight for taller passengers due to the sloping roofline. In their verdict, Autocar considers the A3 a highly recommended premium compact, but not the sportiest; it's an ideal car for those who value comfort and refinement above all else.

Edmunds' comprehensive review of the Audi A3 emphasizes its strong driving dynamics and upscale interior, giving it one of the highest scores in the segment. Reviewers observed that the A3 feels sportier than its predecessor, with quick steering response and a firm yet compliant suspension that absorbs road imperfections well. The 201-hp 2.0T engine provides ample thrust and returns respectable fuel economy, though the engine stop-start can be abrupt. Edmunds lauds the cabin's design, noting the clean layout, high-quality plastics, and available 12.3-inch digital gauge cluster. They also appreciate the standard advanced safety features, including automatic emergency braking and lane-keeping assist. However, they point out that the A3's lower roofline reduces headroom for taller rear passengers, and the trunk space is adequate but not class-leading. The dual-clutch transmission is quick, but it can be jerky in stop-and-go traffic. Overall, Edmunds concludes that the A3 delivers a premium experience that justifies its price, making it a top recommendation for buyers seeking a compact sport sedan.
