The new Q3 is just over 4.5 centimetres longer, 3 cm taller, and 6 cm wider than the 2025 model, but with a nearly identical 2,681-millimetre wheelbase. That translates to identical legroom in both rows, but a standard reclining and sliding second-row bench seat helps make the most of that space. Scoot that 40/20/40 split-folding bench all the way forward and leave it upright, and the 2026 Q3 boasts 707 litres of cargo space — up from 672 litres in the outgoing model. Cargo room with the rear seat folded also increases from 1,360 to 1,414 litres in total.
While it has lost some first-row headroom compared to the 2025 model, the redesigned Q3 is otherwise an admirable feat of maximizing interior space while keeping overall size in check. However, that doesn’t give it an advantage over other subcompact luxury crossovers. Maximum first-row headroom is about mid-pack, but rear-seat headroom trails all competitors except the Lexus UX. Competitors also offer an additional 2.5 to 5 cm of front-seat legroom. Second-row legroom matches the Volvo XC40 and once again exceeds that of the UX, but it trails the Acura ADX and the Mercedes-Benz GLA.
The Audi offers much more cargo space than its rivals behind the second row. Acura and Volvo provide more space with the rear seats folded, but Audi leads in the configuration that most customers are likely to use. Those extra litres also make a better case for choosing the Q3 over a small sedan as there’s more usable space while carrying passengers. And while the Q3’s 680-kilogram (1,500-pound) towing capacity isn’t remarkable by traditional SUV standards, it’s pretty good for the segment with only the XC40 exceeding it at 1,587 kilograms (3,500 pounds).
The 2026 Q3 also debuts a new control layout. The shifter and turn signal/wiper stalks are replaced with a bar that runs across the steering column. Drivers shift and signal by tapping and flicking small tabs, and there’s a small click wheel for some of the wiper settings. A conventional stalk still handles cruise control. This sounds more confusing than it is, and it makes for a cleaner look, according to Audi. Our only complaint is that it’s easy to accidentally brush the steering wheel touchpads, making it difficult to shift from Park to Drive without also switching radio stations.
Moving the shifter off the centre console also frees up more space for cupholders and a cooled 15-watt wireless device charger. The door panels also have a surprising amount of storage space with a deep crevice aft of the expected bottle holder.
