A 0.2 secs quicker time at the 0-30mph will cut down to 0.1 by the 60mph mark; at the moment the vehicle reaches 110mph (around the quarter mile distance) it will be about 0.08 - 0.07 secs or even less since other detracting factors increase their effect in a non linear manner as speed grows, such as rolling resistance from drive-train components and aerodynamic drag just to name two of them.
WTF is this? .3 faster to 60 is .3 faster to 1/4 mile. The slower car isn't catching up.
