The Audi S5 Cabriolet, which followed shortly after the launch of the updated A5 product line, is powered by a V6 gasoline engine. With an output of 260 kW (354 hp) and 500 Nm (368.8 lb-ft) of torque, the latter from 1,470 to 4,500 rpm, the turbocharged, 3.0 TFSI accelerates the open-top four-seater from 0 to 100 km/h (62.1 mph) in 5.1 seconds. Its sound is discrete and sonorous, never intrusive.
The V6 is packed with high tech. Its exhaust end lies inside the 90° vee, the short gas paths and the twin scroll charger, which prevents unwanted interactions between the gas columns, provide for spontaneous throttle response. The B-cycle combustion process, which is designed specifically for part load, makes the V6 gasoline engine particularly efficient. The power flows through an eight-speed tiptronic and the optional sport differential.
At just 172 kilograms (379.2 lb), the 3.0 TFSI is unusually light. Its aluminum crankcase features integrated, thin-walled cylinder liners of gray cast iron. The rings on the aluminum pistons reduce friction. Another efficiency element is thermal management with separate cooling loops for the crankcase and cylinder head. The exhaust manifold is integrated in the cylinder head, and coolant circulates around it which helps to heat up the engine quickly after a cold start.
Power transmission in the Audi S5 Cabriolet is via the combination of an eight-speed tiptronic and quattro permanent all-wheel drive. Rounding it out is wheel-selective torque control. Audi offers the optional sport differential, which actively distributes drive torque between the two wheels during spirited cornering to further enhance handling and stability.
A sportily tuned suspension is standard, with damper control available as an option. If present, it is integrated into the Audi drive select dynamic handling system. The powerful Cabriolet rolls standard on 18-inch wheels with 245/40 tires. 20-inch wheels are optional. On the front axle of the Audi S5 Cabriolet are ventilated brake discs measuring 350 mm (13.8 in) in diameter. They are gripped by black (or optionally red) six-piston fixed calipers with S logos. Distinctive design details complete the dynamic appearance of the Audi S5 Cabriolet, whose interior exudes a subtle, sporty elegance.
