It's not strictly a two-seater, but the 2011 Audi A5 has a lot more room for front passengers than it does for those in the back.
Both the A5 Coupe and Cabriolet start with supportive front seats mounted to grant good leg and head room. There's a firmness to the seats that feels good after covering long distances, though the bolstered buckets in the sporty S5 coupe and convertible would be a great addition to the options list, too--though the available S-line sport seats are close. Like most cars in this class, the headroom is snug when the optional panoramic sunroof is fitted on Coupe models.
The rear seats in the coupe are small and can be difficult to get into, even with the A5's long doors. Once they're wedged in back, adults will find almost no legroom and not much more headroom under either the hard or soft roof. The relative lack of room is more pronounced in the Cabriolet, since it's a bit narrower across the back where its top is hinged to the body. Still, compared to some other four-seat convertibles--cars like the Volkswagen Eos--the A5 Cabriolet's rear seats are relatively roomy.
The rear seats are split to fold down in equal portions, or together, which boosts access to the trunk. Even in the Cabriolet, the cargo hold has space for a fair amount of luggage; it hangs on to 11.3 of the Coupe's 16.3 cubic feet of trunk space, even when the top is folded down.
The A5 affirms Audi's reputation for high-quality interiors. Surfaces have a low-gloss luster, and the cockpit shows the company's mastery of mixing plastic, leather, and wood in the right proportions.
