Audi S4 Cabriolet

A powerful, attractive-sounding eight-cylinder engine generating 253 kW (344 bhp) and 410 Newton-meters, the latest generation of quattro permanent four-wheel drive and a design that creates an air of restrained dynamism: these are the hallmark characteristics of the new Audi S4 Cabriolet. The 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 front end, with the single-frame radiator grille, is visible evidence of the new generation of the S4 Cabriolet. Like the S4 saloon, the Cabriolet features the S specific grid pattern and the redesigned standard xenon headlights.

The bumpers with large air inlets, the aluminum-look casings for the exterior mirrors, the redesigned rear lights and the four oval tailpipes are the distinguishing visual features of the S4 Cabriolet. The Audi S4 Cabriolet is fitted with 18-inch cast aluminum wheels of S design with 235/40 R1 8 tires.

Inside, too, the S4 Cabriolet differs in appearance from its brothers. The instrument cluster has the grey dials that are characteristic of S models and special needles.

The electrically adjustable sports seats with a combined leather/Alcantara upholstery are outstandingly comfortable even over long distances. The seats come with an adjustable thigh support and electrically adjustable lumbar support as standard. The new generation of steering wheels now also features in the Audi S4 Cabriolet, with the impact absorber echoing the design of the single-frame radiator grille.

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-meters 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 millimeters. 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.

The lightweight aluminum suspension consists of four-link front and trapezoidal-link rear suspension, and is designed to ensure maximum steering precision and clearly defined road behavior with excellent lateral stability. A low unsprung mass produces a particularly sensitive response from the suspension.

Like the S4 saloon and the Avant, the S4 Cabriolet features firm sports suspension. This provides the ideal basis for maximum agility and, consequently, sheer driving pleasure.

The standard servotronic steering always strikes a good balance between steering precision and lightness, at whatever the speed.

Thanks to quattro, the Audi S4 Cabriolet can translate engine power into optimal progress in any conditions and exploit the dynamic potential of its aluminum running gear with a new degree of supremacy. In other words: driving pleasure in the purest sense.

In common with the Audi RS 4, the new Audi S4 Cabriolet has the latest generation of quattro permanent four-wheel drive as standard. With the torque split of 40 (front wheels) to 60 at the rear wheels (manual-gearbox version), it provides even greater agility and a steering feel that is virtually free from feedback from the driveline.

Even in the planning phase, Audi’s body developers worked systematically on the structure of the body and simulated its reaction to movements of the suspension and the mechanical assemblies. The result of this development process is that no disagreeable levels of either high or low-frequency vibration reach the passenger area on roads of any kind.
