Texas-based hypercar manufacturer and high-performance vehicle creator, has unveiled its ‘H1000’ Cadillac CT5-V Blackwing. Boasting a supercharged 1,000 horsepower V8 the rear-wheel drive Cadillac is “a herculean muscle car wearing an elegant tuxedo”. Straight from the factory, the Cadillac CT5-V Blackwing is Hennessey’s most powerful production car ever. Under its hood is a supercharged 6.2-liter small-block LT4 V8 engine rated at 668 horsepower and 659 lb-ft of torque. Offered with a 6-speed manual and a 10-speed automatic, both variants sprint to 60 mph in 3.5 seconds and boast a top speed of over 205 mph. Hennessey’s engineering team, upgraded the stock Cadillac CT5-V Blackwing to hypercar power levels. First, its LT4 receives ported cylinder heads, enhanced intake and exhaust valves, improved lifters and pushrods, oversized heat exchangers, and long-tube stainless steel headers. Then GM’s small block is fitted with a high-flow supercharger, replacing the factory unit. Lastly, Hennessey’s engineers upload Hennessey Engine Management Calibration (HEMC) for its new mission. The result is a dyno-proven 1,000 bhp and 966 lb-ft torque. That immense power shaves a full second off the 0-60 mph sprint, drops the ¼ mile run to 10.1 seconds, and pushes the top speed to well above 200 mph. Hennessey’s prodigious power upgrade complements Cadillac’s performance enhancements, including adaptive Magnetic Ride Control, Brembo brakes, and configurable driving modes for every situation. An integrated data recorder logs performance both on- and off-track. The ‘H1000’ upgrade is backed by Hennessey’s comprehensive 2-year / 24,000-mile limited warranty. The upgrade only applies to the Cadillac CT5-V Blackwing (not the standard Cadillac CT5-V, fitted with a V6). Production of the new Hennessey ‘H1000’ Cadillac CT5-V Blackwing will begin in August 2023.
