The exaggerated difference makes it looks like the GT3 RS traps 20 miles per hour higher than the Caddy. The way the race should look is the CTS-V's torque advantage keeps it with the GT3 RS at the start as the GT3 RS slowly edges it out and pulls gear by gear.
Let's get real here, the CTS-V traps just over 121 miles per hour in the 1/4 mile and makes 580 lb-ft of torque to the wheels from a positive displacement blower. It has a mountain of torque early in the rev range. The GT3 RS is maybe a 127 car on a real strip and not in a magazine test.
This race should not look like this and it's another example of Gustav muddying the waters for views.
