Its 2.0 TFSI engine develops 300hp and delivers 380nm of torque but, with S-tronic, consumes just 7.1 litres of fuel per 100km on average and 165g of CO2 per kilometre.
Absolute lightweight construction and a high-performance chassis complete the profile of the Audi S3 Cabriolet.
The S3 has a soft top with an electro-hydraulic drive.
Magnesium, aluminium and high-strength steel keep its weight low.
A highly insulating foam layer in the roof reduces the noise level in the interior.
The top is available in three colours. It opens or closes in 18 seconds, even while driving at speeds up to 50km/h.
Many design details hint at the dynamic driving potential of the S3.
The Singleframe grille, surrounded by a chrome frame, features a platinum-grey insert and double cross-struts with an aluminium look.
The air intakes are framed by powerful edges and filled with double ribs and honeycomb inserts. S3 badges adorn the front and rear.
With S-tronic, the open-top four-seater accelerates to 100km/h in 5.4 seconds.
The Audi S3 Cabriolet weighs 1,620kg.
The passenger compartment consists primarily of ultra-high-strength steel, and the hood is made of aluminium.
When the standard Audi drive select dynamic driving system is operating in dynamic mode, S3 has a heightened throttle response, and the engine revs up briefly when the S-tronic shifts gears.
The sound flaps in the exhaust system open as the load and rpms increase.
In the standard six-speed S-tronic transmission, the bottom gears are close-stepped for a sporty effect, whereas the long gear ratio of the top gear lowers rpms and therefore fuel consumption.
During a starting manoeuvre at full throttle from a standstill, Launch Control, another feature of the dual-clutch transmission, ensures that the power of the engine is transmitted to the road with a defined tyre slip.
S3 Cabriolet deliveries in Ireland will commence this summer - at an on-the- road price of €58,950.
