Audi S4 Cabriolet: An open-top sports car

The Audi S4 Cabriolet, an open-top four-seater, crosses the genes of an open sports car with those of an elegant cruiser – a car that offers fascination for all the senses.

The Audi S4 Cabriolet is propelled by a 253 kW (344 bhp) eight-cylinder engine. Its maximum power output is in the region of 7,000 rpm. The 4.2-litre engine delivers a hefty 410 Newton-metres of torque to the crankshaft at an engine speed of 3,500 rpm. Thanks to such a superior power flow from the substantial displacement, this naturally aspirated engine acquires an air of supreme confidence.

Its spontaneous response to every movement of the accelerator and its astonishingly free-revving nature are impressive. The deep, sporty sound of the exhaust system is very immediate, but never over-assertive.

The Audi S4 Cabriolet sprints from 0 to 100 km/h in only 5.9 seconds, and reaches a top speed of 250 km/h, at which point the governor cuts in smoothly.

Surprisingly, the overall length of the eight-cylinder engine is incomparably short at just 464 millimetres. Audi's engine developers achieved this compactness by means of a chain drive for the camshafts and auxiliaries. The weight is also extremely low for an engine with eight cylinders, at only
195 kilograms. This has definite advantages in terms of the car’s weight distribution and road dynamics.

The engine power passes via a precision-shift 6-speed gearbox. The selector mechanism is decoupled, largely preventing vibrations and load-reversal movements from being transmitted to the gear lever.

The optional extra of 6-speed tiptronic with Dynamic Shift Program, an additional Sport program and shift paddles on the steering wheel unites sportiness with the convenience of an automatic transmission. Whether relaxed cruising or open-top driving, the Audi S4 Cabriolet permits both.
