Mirroring its closed top sibling stylistically, but measuring 47 mm longer in overall length with a 14 mm wheelbase extension versus the previous cabriolet, the new A5 also sees a 40 kg drop in weight with the cloth roof able to open in 15 seconds, and close in 18 seconds at speeds up to 50 km/h.
As well as a 26 mm gain in shoulder room and 18 mm in rear knee room, boot space now measures 320-litres with the roof down, or 380-litres with the top up. Torsion rigidity has also gone up by 40% which Audi claims makes the A5 the stiffest in its class.
Available with a full set of driver assistance systems, both standard and optional, new tech on the cabriolet includes Adaptive Cruise Control with start/stop and Traffic Jam Assist, Pre-Sense City which automatically brakes when another vehicle or pedestrian is detected, the 12.3-inch Virtual Cockpit Display, MMI Plus incorporating Apple CarPlay, Android Auto, satellite navigation and Wi-Fi, and wireless smartphone charging.
Model-wise, the cabriolet will be initially be offered only with a 2.0-litre TFSI petrol engine or a 3.0-litre TFSI V6 in the case of the S5, with a 2.0-litre TDI expected to arrive at a later stage.
Serving up 140 kW and 320 Nm of torque, the base front-wheel drive cabriolet features 17-inch five-spoke alloy wheels, Xenon Plus headlights with separate daytime running LEDs, aluminium door sills, cruise control, tyre pressure monitor, MMI Plus and Audi Drive Select as standard, while the second-tier Sport adds sport front seats, S-Line bumpers and grille and 18-inch alloy wheels.
Featuring the same engine and seven-speed S tronic gearbox, the next step up quattro does however deliver 185 kW and 370 Nm of torque, and comes fitted with electric front seats and rear parking sensors as standard.
Sitting at the top of the range, the S5 retains its 2,995 cc displacement, but drops the supercharger for a turbo with power going up from 245 kW to 260 kW, and torque from 440 Nm to 500 Nm. Audi claims a 0-100 km/h sprint of 5.1 seconds and top speed limited to 250 km/h.
Standard spec on the S5 includes 19-inch alloy wheels, Nappa leather seats, S sport front seats with lumbar support and massaging function, S sport suspension, flat-bottomed sport three-spoke leather trimmed steering wheel, LED rear lights with dynamic indicators and Pre-Sense.
A five year / 100 000 km Audi Freeway plan is standard on all models.
