2 Answers
The differences between Audi A4 and Audi A3 are: 1. Different body structures: Audi A4 is a 4-door, 5-seater sedan; Audi A3 is a 5-door, 5-seater hatchback. 2. Different body dimensions: The length, width, and height of the Audi A4 are 4858mm, 1847mm, and 1439mm respectively; the length, width, and height of the Audi A3 are 4351mm, 1815mm, and 1458mm respectively. 3. Different wheelbases: The wheelbase of the Audi A4 is 2630mm; the wheelbase of the Audi A3 is 2908mm. 4. Different suspension systems: The front and rear suspensions of the Audi A4 are both five-link independent suspensions; the front suspension of the Audi A3 is a MacPherson independent suspension, and the rear suspension is a multi-link independent suspension.
As someone who has driven both models, I'd say the main differences lie in the sense of bulkiness and driving experience. The A4 is nearly 30cm longer than the A3 with significantly more wheelbase, allowing three adults to sit comfortably in the back seat, and the trunk can accommodate both a stroller and luggage. The A3 is more suitable for singles or young couples, with the rear seats often used as storage space. In terms of power, even the A4's low-power 2.0T version outperforms the top-spec A3, providing more confidence when overtaking on highways. The interior material quality shows noticeable differences - the A4's dashboard is entirely wrapped in soft leather, while the A3's door panels still contain hard plastics. The steering wheel feel is also distinct: the A4 offers light steering at low speeds and firmness at high speeds, whereas the A3's steering is generally lighter but less precise. The key consideration is usage scenario - the A4 suits frequent long-distance drivers or families with children better, while the A3 proves more agile and fuel-efficient for pure urban commuting.
