Hennessey-tuned Caddy fastest ever sedan

Texas-based auto tuner Hennessey has taken the wraps off its ‘H1000’ Cadillac CT5-V Blackwing sports sedan.

The 1000 part of the name refers to the 1000 horsepower produced by its supercharged V8 engine. That’s 746kW for the rest of the metric world.

Straight from the factory, the unmolested Cadillac CT5-V Blackwing is the car maker’s most powerful production car ever.

Under its bonnet sits a supercharged, 6.2-litre small-block LT4 V8 engine that is rated at 668 horsepower (498kW) and 659 lb-ft of torque (893Nm).

Offered with a 6-speed manual or 10-speed automatic transmission, both variants are able to sprint from 0 to 100km/h in 3.6 seconds and boast a top speed of more than 330km/h.

That was before the Hennessey transformation.

Its engineering team, which has been ‘making fast cars faster’ for more than 30 years, meticulously upgrades the stock Cadillac CT5-V Blackwing to supercar 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 add the secret ingredient — the Hennessey Engine Management Calibration (HEMC) for its new mission.

The result is a dyno-proven 1000 bhp and 966 lb-ft torque — that 1310Nm of stump pulling torque in case you were wondering.

That immense power shaves a full second off the 0-100km/h sprint, drops the quarter mile run to 10.1 seconds and pushes the top speed to well above 330km/h.

Hennessey’s prodigious power upgrade complements Cadillac’s own 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.

Company founder and CEO, John Hennessey said the Cadillac’s CT5-V Blackwing was a natural candidate for its ‘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,” he said.

“It is a rare high-water mark in a segment that will vanish by the decade’s end.”

Production of the new Hennessey ‘H1000’ Cadillac CT5-V Blackwing is set to begin in August.

The ‘H1000’ upgrade is backed by Hennessey’s comprehensive 2-year/40,000km limited warranty.
