One of our core targets is to dissolve the contradiction between efficiency and performance by delivering CO2-neutral mobility without compromise. Audi ultra is more out of less. Audi ultra is the sum of our most efficient ideas.
Anything to be slim
Being the ideal weight and having a dream figure are not only concerns in the beauty industry. Automotive engineers also have to think seriously about the weight spiral. The key is lightweight construction, and die-cast aluminium plays a major role in achieving it.
More than ten kilograms lighter – thanks to aluminium die-casting, it has been possible to reduce the weight of the two suspension strut caps in the Audi A6 compared with the previous version made of steel.
From zero to 100 km/h in only 1.83 seconds – that is faster than the fastest car in the world. In this short space of time, the aluminium die-casting machine piston presses liquid aluminium into a steel mould, which ultimately gives the structural body component its shape.
It is hot in the foundry. The liquid aluminium in the melting furnace has a slightly red glow. The alloy has now reached a temperature of 720 degrees – perfect for die casting.
Depending on the engine version, the new A3 weighs up to 80 kilograms less than its predecessor. Audi is putting enormous effort into ultra-lightweight design in series production.
