Audi A5 and S5 Cabriolet: The Body
Like every Audi, the A5 Cabriolet has an extremely rigid body. This is the prime reason for its precise, sporty handling, superior ride comfort and high crash safety. Hardly any oscillations or vibrations can be felt in an open A5, not even at the steering wheel or on the seats the comfort points.
Several innovative technologies are used in the construction of the body-in-white. A prime example are the ultra-high-strength steels, which Audi largely fabricates in-house using hot forming. Combining low weight with extremely high tensile strength, they are used in the side sills, the longitudinal members, the center tunnel, the B-pillars and the front cross members.
A whole array of additional reinforcement parts compensates for the absence of a solid roof. In the front section, diagonal struts run from the side sills to the auxiliary frame for the suspension mounts. In the rear section, similar components are integrated beneath the floor of the trunk. The side sills have particularly thick walls. The hydroformed tubes that reinforce the A-pillars from the inside are particularly high-strength and capable of bearing extremely high loads.
Another important component is a solid aluminum frame with integrated roll-over protection located between the cabin and the trunk. When a rollover threatens, electric actuators release aluminum braces pretensioned with powerful springs, which shoot up fast as lightning behind the rear headrests and lock into place, thus expanding the passenger survival space.
Seat-mounted head and thorax side airbags with a volume of 18 liters (0.64 cubic ft) each provide protection in the event of a side impact; full-size airbags protect the driver and front-seat passenger in the event of a frontal collision. Because the control unit knows the seating position, it can adaptively trigger the belts and airbags to provide the best possible protection for passengers large and small in all types of collisions. In a rear-end collision, the integral head restraint system averts the danger of whiplash injuries.
The front fenders of the Audi A5 Cabriolet are made of lightweight aluminum to reduce weight and optimize the axle load distribution. Sophisticated details such as a fully-enclosed underbody improve the airflow and thus the acoustics and also fuel efficiency. With the top closed, the four-seater has a drag coefficient of 0.31 and a frontal surface area of 2.17 m² (23.36 sq ft).
