Self Study Program 278 – The Audi A4 Cabriolet

VAG SSP 278. In over nine years of Audi Cabriolet production, the predecessor model acquired itself the status of a “modern classic”. The long-awaited new generation also has all the makings of a vehicle heading for stardom:

With a length of 4,57 metres and a width of 1,77 metres, this vehicle lends new expression to the classical elegance of the Audi Cabriolet whilst at the same time emphasising the sporty character of the make.

The philosophy behind the new Audi A4 Cabriolet concept is to create the ideal allyear-round vehicle.

A standard feature of the new Audi A4 Cabriolet is a fully automatic electrohydraulic convertible top with a heated glass rear window.

It goes without saying that the Audi Cabriolet convertible top offers outstanding thermal insulation to provide not only perfect winter protection but also ideal sound absorption.

At the touch of a switch in the centre console, the convertible top can be completely opened or closed in only 24 seconds.

It can also be operated from outside by inserting the vehicle key in the driver’s door lock.
