I also struggled between the Audi A3 and A4 when I changed cars. The A3 is a compact model, perfect for city driving with super convenient parking, though the rear seats are a bit cramped. For someone like me commuting alone, it's totally sufficient. The A4 is significantly larger, a mid-size sedan with a longer wheelbase, offering more legroom and even space for a baby stroller, making it more suitable for families with kids. Price-wise, the A3 starts at over 200,000 yuan, about 50,000 to 60,000 cheaper than the A4. However, the A4 feels more stable on long drives with better sound insulation. I test-drove both—the A3 has a light and nimble steering wheel, very agile, while the A4 feels more solid and doesn’t wobble on high-speed turns. Maintenance costs are similar, but the A4 has slightly higher fuel consumption. If you're on a tight budget and love agility, go for the A3; if you want more space and comfort, head straight for the A4.
Having driven both the Audi A3 and A4, the difference in driving experience is quite noticeable. The A3 is built on the MQB platform, with a lightweight body and precise steering, making it feel like driving a toy car when maneuvering through city traffic, and parking is a breeze. However, at highway speeds, the wind noise is more pronounced, and the stiffer suspension makes bumps and speed bumps quite jarring. The A4, on the MLB platform, is heavier and more stable, offering a sofa-like comfort on the highway with much better vibration absorption. In terms of power, the A3 offers a 1.4T option for quick starts, while the A4 mostly comes with a 2.0T, providing stronger acceleration and effortless uphill climbs. The steering feedback in the A4 is more refined, whereas the A3 feels more sensitive. Space-wise, the A4 clearly wins, with a roomy back seat that comfortably fits three and a larger trunk. If you prioritize driving fun and agility, the A3 is sufficient; but for long-distance comfort, the A4 is the way to go.
