Troublesome task

Troublesome taskYesterday had I an opportunity to load four Hi-Ace tire wheels on the back of the Audi A3 DBA-8 PCAX and run. It's just as same as two adults sitting in the back seats.
As a matter of fact, the state where the tail was raised became almost horizontal and became a natural silhouette, so the design intention is supposed to be a state where an appropriate load is applied to the rear part.
Also, in a four-wheel independent suspension system, the vehicle changes the wheel alignment and axle geometry of all four wheels depending on the rear weighting condition.

The apparent change like a different car in straightness seems to be due to the increase in front casters due to rear subsidence compared to it's single driver ride.
It is known that a slight difference in thrust angle within 1 minute angle value affects straightness, so this point caused by rear wheel alignment also needs to be considered as an uncertain factor.

A car manufacturer's R & D technician can be easily imagined that it would be a daunting task as he must finish the product in consideration of all conditions of use.

There is no easy job in the world
