Audi has opened the UK order books for the range-topping model of its new A5 Cabriolet, the S5. Prices start from £42,245 OTR with first deliveries expected to arrive in October. The rag-top S5 Cabriolet is powered by the same supercharged 3.0-liter six-cylinder engine that's found under the hood of the latest S4 Sedan and Avant models. It produces an output of 333 HP and 440 Nm of torque from 2,500-4,850 rpm. Equipped with Audi's quattro four-wheel-drive system, the S5 is offered exclusively with a seven-speed S tronic twin-clutch sports transmission. According to the German automaker, the 3.0 TSI powers the S5 Cabriolet to 62mph (100km/h) in 5.6 seconds and on to an electronically governed top speed of 155mph or 250 km/h.
