I have never figured out why Audi warns about 130 mph (or actually limits
the car to 130 mph) then fits V-rated tires to the cars.  The '91 200q
owners manual says the tires are V-rated and should not be used over 130 mph.  

BTW, the '91 200q does NOT have a limiter, but the '92 100s does;  don't
know if the '91 100 had a limiter.  I'm guessing that the older 10v NA I5
(110-130 hp) engines could NOT redline in 5th whereas the V6 (172 hp) cars
can.
