2016 Audi A4 – How It Lost 120 Kilograms

Despite being bigger than the outgoing B8, the all-new 2016 Audi A4 B9 is actually a lot lighter. This was possible by using an intelligent combination of materials and a lightweight construction which has resulted in a considerable diet of up to 120 kg (264.6 lbs), depending on engine. The body alone is now up to 15 kg (33.1 lbs) lighter than before while the new aluminum cables and AGM battery have shaved off an additional 6 kg (13.2 lbs).

Audi’s engineers were able to reduce the weight of the seats by up to 9 kg while an additional 4 kg (8.8 lbs) have been eliminated thanks to the new carpet, aluminum brake pedal and foamed defrost ducts in the air conditioning system.

In addition, the newly developed six-speed manual gearbox standard on all TFSI engines and on the four-cylinder TDI units is now 16 kg (35.3 lbs) lighter than the old one. This was possible by making the housing mostly out of magnesium while the open gearwheels, hollow shafts and a smaller clutch also contributed to this significant weight loss.

An additional 6 kg have been shaved off from the front axle which now makes more extensive use of forged aluminum and there’s a new electromechanical power steering system that has saved 3.5 kg (7.7 lbs). The lightweight components of the rear axle have reduced weight by another 5 kg while the newly developed brakes are 5 kg lighter than before.
