What is the Audi A2's 'Spaceframe' chassis made out of?

I am wondering what material is used to construct the lightweight 'Spaceframe' chassis in the Audi A2. Does it provide any benefits in terms of performance or safety? Does it require any special maintenance?

The Audi A2's 'Spaceframe' chassis is constructed using an advanced aluminum alloy which is both lightweight and durable. This material allows for improved performance and handling, as well as increased safety in case of impact. However, it does require specialized maintenance in order to ensure its longevity and structural integrity.

The 'Spaceframe' chassis in the Audi A2 is made out of an aluminum-magnesium alloy, commonly used in aerospace industry. This gives the car a strong yet lightweight structure, resulting in improved fuel efficiency and overall performance. Additionally, this material has a longer lifespan and requires less maintenance compared to traditional steel frames.

The Audi A2's 'Spaceframe' chassis is made out of a combination of aluminum and superformed steel, giving it a strong and rigid foundation while also keeping it lightweight. This allows for better handling and maneuverability, as well as increased efficiency in terms of fuel consumption. Special maintenance may be required to prevent corrosion, as these two metals are not compatible.
