Hello, I asked myself several times, since we had an A2 in the family, why Audi could achieve such a low weight for a fully grown car (one observes the space in the interior). Sure, the A2 had an aluminium body. So far so good. But the new i3 is heavier than the expired Audi A2 1.2 TDI. Even with the battery of the i3 the Audi would have been lighter.Weight A2 1.2 TDI (without driver) – 855kg weight i3 without REX (without driver) 1195 kg battery weight of the i3 – 230kg So why is the i3 heavier, despite the carbon fiber passenger cell? Carbon is about 50% lighter than aluminium. Is it because the thermoplastic planking weighs extra weight for the i3? It is also important to remember that the engine and the gearbox weighs significantly more than the electric motor from the BMW. Since all the auxiliary units from the Audi bring a lot of weight with them. It is clear to me that the carbon is not the same as carbon and that there are also differences in aluminium. Audi simply did a job that was too good as a lightweight world champion at the time, or why is the i3 heavier now?
