IMHO its simple.
JHM is proven not just with the S6 and S8 but with ALL of the NA Audi motors. APR the next popular brand isn’t even close and when I say not even close I mean not close like solar system not close.
JHM has over .8 faster and in some cases 7mph or more of a difference between them and the competition in acceleration testing.
When you look at it JHM holds by a large amount the fastest
B6 A4 3.0 Na 1/4 mile record for both auto and manual
B6 S4 4.2 Na 1/4 mile record for both Auto and manual
B7 S4 4.2 NA 1.4 mile record for both Auto and manual
B7 RS4 4.2 Na 1/4
B8 S5 4.2 Na 1/4 record
S6 5.2 1/4 mile record
S8 5.2 1/4 mile record.
As it that wasn’t enough they are still actively supporting our platform.
I never link to troll zine but you can’t argue with this one poll. I know its not from S6 owners but it helps prove a point.
