The new model adopts a supercharged V6 TFSI engine in place of its naturally aspirated V8 which promises to maximise efficiency without diluting driving pleasure.
The supercharged V6 delivers peak power of 245kW and 440Nm between 2,500 and 4,850rpm, mated as standard to a seven-speed S tronic twin-clutch transmission.
This is coupled with the latest evolution of Audi's quattro all-wheel-drive system which is capable of varying torque not only between front and rear axles but also between each rear wheel with an optional sport differential.
The result is zero to 100km/h acceleration in just 5.6 seconds with a top speed limited to 250km/h.
Despite its performance, the new S5 Cabriolet emits just 224g/km of CO2 with a combined fuel economy figure of 8.0 litres per 100km.
Unique ‘S’ sports suspension complements the quattro system and sport differential allowing them to operate at optimum efficiency, while also lowering the S5 Cabriolet body to within millimetres of its 19-inch five spoke alloy wheels.
Aluminium-look door mirrors, xenon plus headlights with LED daytime running lights, rear LED lamps, special ‘S’ front and rear styling treatments and black painted brake callipers bearing the S5 logo will also be distinguishing features.
Its soft-top acoustic hood reduces external noise intrusion into the cabin to virtually the same level as the fixed head Coupe and can retract in just 15 seconds at speeds of up to 50km/h.
With the soft top in place, a best-in-class luggage capacity of 380 litres enables easy accommodation of luggage for each of the four passengers.
