The main differences between the Audi Q3 and Q5 are as follows: 1. Different vehicle positioning: The Q3 is positioned as a compact SUV; the Q5 is positioned as a midsize SUV. 2. Different engine layouts: The Q3 features a transverse engine layout; the Q5 features a longitudinal engine layout. 3. Different chassis: The Q3 has a front MacPherson and rear four-link suspension structure; the Q5 has a front five-link and rear trapezoidal link suspension. 4. Different dimensions: The Q3 measures 4495mm in length, 1848mm in width, and 1616mm in height; the Q5 measures 4765mm in length, 1893mm in width, and 1659mm in height. 5. Different wheelbases: The Q3 has a wheelbase of 2680mm; the Q5 has a wheelbase of 2908mm. 6. Different drivetrain configurations: The Q3 can be equipped with either front-wheel drive or all-wheel drive; the Q5 is exclusively all-wheel drive. 7. Different combined fuel consumption: The Q3 has a combined fuel consumption of approximately 6.3 to 8.3L; the Q5 has a combined fuel consumption of approximately 8.2 to 9.6L.

The biggest difference between the Audi Q3 and Q5 is space. The Q5 has a wheelbase nearly 20 cm longer, allowing over two fists of knee room behind the front seats when sitting in the rear. Last time I carried three friends plus luggage without feeling cramped, and the trunk is half a foot deeper than the Q3. Tall passengers might find their heads touching the roof in the Q3's rear seats, and you'd need to remove the wheels to fit a stroller. On the road, the Q5's heavier chassis provides better stability at high speeds without floating, though its steering feels heavier, requiring extra turns for urban U-turns. The Q3 is much more agile, easily slipping into tight mall parking spots in one go, with about half a liter lower fuel consumption. However, it delivers a noticeably bumpier ride over speed bumps.

The difference in power is quite noticeable. The base model Q5 comes with a high-power 2.0T engine, delivering much stronger acceleration and a more pronounced push-back feeling compared to the Q3, especially when overtaking on highways. The entry-level Q3 is equipped with a 1.5T engine, which is sufficient for daily commuting but struggles when fully loaded or climbing hills. The transmission tuning also differs—the Q5 shifts faster and more smoothly, and its sport mode maintains higher RPMs, with more robust suspension support when tackling mountain roads and corners. However, the Q3 feels more nimble, making it more convenient for stop-and-go traffic in urban areas, and its braking system prevents the car from diving forward when braking.

The main differences in configuration lie in the sense of luxury. The Q5 features more leather upholstery, with a particularly satisfying damping feel to the center control knob, and offers 32-color ambient lighting at night. It comes standard with a power tailgate and B&O audio system across all trims, with even the base model including heated leather seats. In contrast, the Q3 has noticeably more plastic components, with cloth seats in the lower trims, requiring an upgrade to higher specifications for a full digital instrument cluster. In terms of safety features, the Q5 includes lane departure correction and blind-spot monitoring, with faster automatic braking response. However, the Q3's infotainment system is more up-to-date, supporting new features like wireless CarPlay and remote temperature control.

Value for money depends on needs. The Q5 costs over 100,000 RMB more than the Q3, with maintenance fees approximately 600 RMB higher per service. However, the Q5 has significantly better resale value – retaining about 50% after five years, whereas the Q3 may drop below 35%. Features like premium audio and driver assistance systems, which require 20,000-30,000 RMB in optional packages for the Q3, often come standard on the Q5. A friend spent 320,000 RMB on a fully-loaded Q3; for just 70,000 RMB more, they could've gotten a base Q5. If you frequently take long trips or entertain clients, this price difference absolutely justifies itself.
