[s-cars] Vibration

[Ray Tomlinson]

Every Audi I have owned since 1988 (Audi 90q, 90Q20v, CQ, A4, S6) had a CF
front section on the prop shaft.  I believe it was a safety issue - the CF
shaft would shatter upon impact, preventing the steel shaft from coming
through the floor of the car and injuring passengers.

I would have to imagine that any impact hard enough to deploy a steel
driveshaft through the floor of the passenger compartment would leave me in
pretty bad shape to begin with.  Of note is that the replacement cost of the
CF shaft is only abotu 3x the steel . . ..
