The A4 isn’t the only Audi range that’s set to expand – as these grainy spy shots prove. This is the A5 Cabriolet, which will signal the end for the current A4 drop-top when it makes its world debut on the stands at the Paris Motor Show next month.

Our spies caught the cabrio on Switzerland’s mountain roads, and snapped it with its cloth roof down for the first time. Engines will be carried over from the A5 coupé range, with petrol units ranging from a 168bhp 1.8 to a 3.2-litre V6, along with 2.7 and 3.0-litre TDI diesels. An S5 is expected to follow later.
