AUDI HAS REVEALED its A5 Cabriolet and hot S5 Cabriolet models ahead of their LA motor show debut. Shadowing its coupe sibling with its platform, styling, engines and technology, the soft-top A5 uses a one-touch automatic operation to open the roof in a claimed 15sec at vehicle speeds of up to 31mph. Audi claims the cabrio’s body is the stiffest in its class, with torsional rigidity up by 40% over the previous A5 Cabriolet.
The structure has been stiffened by, among other measures, reinforced sills and extra strengthening in the bulkheads to offset the lack of a fixed-roof structure.
Audi says the model is also the lightest car in its segment. The kerb weight of the front-wheel-drive A5 Cabriolet 2.0 TDI is claimed to be 40kg less than that of its direct predecessor, at 1690kg. At launch, there will be a 248bhp turbocharged 2.0-litre petrol engine and two diesels: a 2.0-litre four with 187bhp and a 3.0-litre V6 delivering 215bhp. The S5 Cabriolet receives Audi’s new turbocharged 3.0-litre V6 petrol engine with 349bhp.
That’s 21bhp more than its predecessor’s supercharged 3.0-litre V6. The new S5 Cabriolet is claimed to hit 62mph from standstill in 5.1sec and reach a top speed limited to 155mph.
Also under development by the Audi Sport division, but yet to be officially confirmed, is an RS5 Cabriolet. Planned for launch next year, it is set to run a twin-turbo 2.9-litre V6 developed in partnership with Porsche in place of the naturally aspirated 4.2-litre V8 used by the previous RS5.
