Audi proves tremendous performance can come in tiny packages with the boisterous RS3. The compact sports sedan looks aggressive enough to suggest it's more than an ordinary four door. Behind its intake-heavy façade sits a 400-hp turbocharged five-cylinder engine that feeds a snappy automatic transmission and a proficient all-wheel-drive system. This unit delivers rapid acceleration that is backed by a joyfully unique exhaust note. A clever personalised plate ‘CURS3D’ not only suits its wicked 5pot personality but also has ‘RS3’ within the combination. Behind the wheel, the littlest RS sedan creates big smiles thanks to its playful agility and willingness to be driven hard. While its back seat is small and its price tag is large, the Audi RS3 primarily exists to entertain drivers who are more focused on thrills than bills.
