The Cadillac CT5-V Blackwing is pretty nuts right out of the box, mixing the traditional Caddy luxury with a rip-snorting supercharged V8 engine. Now, however, Hennessey Performance Engineering is turning up the wick with a new package that increases output to break into the four-figure range. Incredibly, the package even comes with a warranty.
Appropriately named the H1000 upgrade, the new Hennessey package turns the Cadillac CT5-V Blackwing into “Hercules in a tuxedo,” laying down a claimed 1,000 horsepower and 966 pound-feet of torque. For the sake of comparison, the standard Cadillac CT5-V Blackwing is rated at 668 horsepower and 659 pound-feet of torque. The extra oomph translates into quicker performance numbers, with the package clipping a full second off the stock vehicle’s 3.5-second 0-to-60 mph time. The package also enables a quarter mile time of 10.1 seconds, while top speed eclipses the 200-mph mark.
“Cadillac’s CT5-V Blackwing, fitted with GM’s supercharged LT4, was a natural candidate for our Exorcist upgrade as it improves power considerably without affecting drivability,” says company founder and CEO John Hennessey. “Resurrected as an ‘H1000’, the four-door Cadillac is the fastest combustion-only luxury sedan on the planet. It is a rare high-water mark in a segment that will vanish by the decade’s end.”
The Hennessey-tuned H1000 Cadillac CT5-V Blackwing upgrade includes a number of tasty tidbits highlighted by a new high-flow supercharger. Complementary mods include improved lifters and pushrods, enhanced intake and exhaust valves, ported cylinder heads, long-tube headers, and oversized heat exchangers. The whole shebang is controlled using Hennessey’s engine management calibration.
Critically, the H1000 upgrade for the Cadillac CT5-V Blackwing also includes a two-year / 24,000-mile limited warranty. Production of new Hennessey H1000 Cadillac CT5-V Blackwing units kicks off this August. Interested customers should contact Hennessey directly for more information.
