‘H1000’ Cadillac: Hercules in a Tuxedo.

The 'H1000' Cadillac CT5-V Blackwing, the hero of luxury sport sedans, has been introduced by Hennessey, the renowned Texas-based hypercar manufacturer and designer of high-performance vehicles. The rear-wheel drive Cadillac is a mammoth muscle vehicle dressed in an exquisite tuxedo, with a supercharged 1,000 horsepower V8 and sumptuous accoutrements.

The Cadillac CT5-V Blackwing is the automaker's most powerful production vehicle ever, right out of the factory. The 6.2-litre small-block LT4 supercharged engine is capable of producing 668 horsepower and 659 lb-ft of torque. Both versions, which come with a 6-speed manual and a 10-speed automatic gearbox, can reach 60 mph in less than 3.5 seconds and have a peak speed of more than 205 mph.

Hennessey's technical team, which has been "making fast cars faster" for over 32 years, painstakingly upgrades the factory-built Cadillac CT5-V Blackwing to supercar power levels. The LT4's first additions include ported cylinder heads, improved intake and exhaust valves, better lifters and pushrods, bigger heat exchangers, and long-tube stainless steel headers. The OEM supercharger is then replaced with a high-flow supercharger on the GM small block. The company's engineers then upload the Hennessey engine management calibration (HEMC) for the upcoming mission.

The result is a dyno-proven 1,000 bhp and 966 lb-ft of 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 well above 200 mph.

John Hennessey, company founder and CEO: “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. 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.”

Cadillac's performance improvements, such as adaptive Magnetic Ride Control, Brembo brakes, and adjustable driving modes for every condition, are complemented by Hennessey's enormous power augmentation. Both on-track and off-track performance is logged by an inbuilt data recorder.
