Another reason why torque matters > horsepower. The Vdub makes less torque on paper, but that torque also starts early on from idle, while the Caddy needs like 5500rpm* to achieve its peak torque. Hence the slow acceleration.
The Caddy is still faster on the track, which is why NA cars and SC cars (as well as RWD and even some FWD cars) are better built to achieve optimized cornering skills. Turbo and AWD cars are best built for unprepped straight-line performance.
*Edit: I checked and the peak torque is at 5200rpm.
