In the Corvette, the low hood and the height of the supercharger dictate a dry sump and remote oil reservoir. The relatively tall Cadillac doesn’t have the same hood-height issues, so oil starvation is kept at bay in high-g corners by a deep sump, reducing complexity and weight. Given the differences in their cooling systems and how the two cars breathe (plus the always-lurking horsepower hierarchy dictated by brand management), all of the Z06’s 650 horsepower and 650 pound-feet of torque won't materialize in the Cadillac. Instead, the CTS-V is rated at 640 horsepower and 630 pound-feet. We project a zero-to-60 blitz of 3. 7 seconds en route to a 12. 0-second quarter-mile ET.
