The Audi A5 Sportback is a practical and stylish executive saloon that's also the most user-friendly model in the A5 range. It joins the A5 coupe and cabriolet editions, but adds the flexible appeal of four doors and a spacious boot, which is accessed through a large hatchback that is easy to load. Audi claims the A5 Sportback has no direct rivals in the executive class, but both the new BMW 4 Series and the Mercedes C-Class coupe provide plenty of healthy competition. Plus, while there is much to recommend about the A5 – not least its beautiful design and roomy interior – you might not like the firm ride (especially in models fitted with the large alloy wheels), and the Sportback is not the most fun A5 to drive. The A5 Sportback comes in five main specifications – entry-level standard, then mid-range SE and SE Technik, higher-spec S line and top-of-the-range high-performance S5.
