I have read that one of the major reasons for putting the battery under
the rear seat is weight distribution. The 5000 Quattro (and 100/200Q, S4
too I guess) has near ideal 50/50 weight distribution contributing to
vehicle stability. I have also heard that some cars (BMWs, I think) have their
batteries in the trunk for the very same reason. I guess Audi could have
put the battery in the trunk as well, but they would have to give up valuable
cargo space. According to Consumer Reports, the Audi 5000 has the largest
trunk space in its class.
