Pity the humble, traditional sedan. Not only is it under attack from the burgeoning ranks of SUVs but also curvier, coupe-ier cars like the Audi S5 Sportback.As the name suggests, the S5 Sportback is closely related to the S4, Audi’s traditional performance-oriented mid-size sedan offering.

Five-door styling commands a $7000 premium

Luggage space increases to 480 litres

You can apply throttle very early in the corner confident in the knowledge that the front end will remain stuck to the road and that the diffs beneath you will shuffle the power to where it’s needed most.

Dual air vents, USB ports, separate temperature controls and fold-out storage and cupholders all aim to make life more appealing, too.Up front, there are some odd ergonomic quirks. The button placement feels to be a legacy from left-hand drive cars. The Drive Select button is an awkward stretch for drivers, and the with the nearest button to the driver in RHD cars is for turning off the infotainment system.

Small niggles aside, the S5 Sportback is a deeply impressive machine. It’s fast, sounds good, looks good, is practical and feels expensive. It is also painless to drive slow and exciting to drive quickly.

Styling is subjective, but for me the swoopy Sportback body has curves that the traditional three-box sedan can’t hope to imitate. This is one of Audi’s best offerings.
