Its an S4 vs C63....
Previous cars.... Golf GTi- A4 1.8Tq- S3- S4-V8- M3-V6- TT 3.2q 08'- A4 Cab 2.0T q- A5 3.0TDi q
Supercharged Audi as well... you can hear the sc off the line, as it passes the camera.
We've taken our C63 and Rs4 to the 1/4 , once the C63 hooks up, it passes the Rs4 before the 1/8th mile mark, and keeps pulling all the way though the quarter.
Just my personal experience.
I WANTED the Rs4 to do better... but $15k to add the s/c to the Rs4 would narrow the gap as seen in the video.
