Audi already refreshed the A5 and S5 Coupe and Sportback and so now it is the turn of the Cabriolet – and the big news is it is bigger but lighter than the predecessor and can drop its fabric roofs in just 15 seconds.

The A5 and S5 share their design with their hard top counterparts but Ingolstadt has made sure to give them the stiffest and one of the lightest body in its class. Compared to the outgoing model, torsional stiffness has been improved by 40 per cent and thanks to the use of even more lightweight materials than before, Audi has trimmed 40kg off the car. The lightest of the lot is the front-wheel drive A5 with a 190 horse 2.0-litre TDI engine which tips the scales at 1,690kg. The design is now sharper than before and the soft-top can be removed at up to 50kph and in 15 seconds (to put it back up, it takes 18 seconds...) and is now roomier than its predecessor due to the wheelbase being stretched by 14mm which has added 18mm of rear legroom. Up front, it has an extra 26mm of shoulder room too. Usually, when you drop the roof of a convertible it eats up a lot of boot space but the new soft-top has an extra 60-liters of room (total of 380-liters when the roof is up) which will come in handy for the grocery run.

As for the engines, they are borrowed from the Coupe and Sportback which means there is a massive choice; there are four- and six-cylinder motors aplenty with the range topper being the turbocharged 3.0-litre V6 making 354 horsepower and 500Nm of torque for the Quattro S5. It can hit 100kph from rest in 5.1 seconds and has a top speed of 250kph. It could be left in the dust when Audi gives us the RS5 Cabriolet (rumoured to be next year) which will borrow the biturbo 2.9-litre V6 from the Panamera 4S; the Porsche has 440 horses and 550Nm of torque, but we expect the numbers will be slightly less when Audi gets the motor.
