So, what exactly did the master engineers do to the CT5-V Blackwing at the Hennessey garage? They went nowhere short of above and beyond, as their mantra is, and has been since 1991, “Making fast cars go faster.” First, the sleek luxury sedan received engine upgrades, with GM’s supercharged LT4 V-8 getting rebuilt and fitted with a larger supercharger and upgraded calibration, as well as ported cylinder heads, enhanced intake exhaust valves, improved lifters and push-rods, oversized heat exchangers, and long-tube stainless steel headers. A high-flow supercharger replaces the factory unit as the ‘H1000’ upgrade progresses on the CT5-V Blackwing. Finally, there’s the Hennessey Engine Management Calibration (HEMC), which is finely tuned ECU data that effectively supercharges the brain of the vehicle.

Notable Hennessey Upgrades:

  • Fitted with larger supercharger
  • Upgraded calibration
  • Ported cylinder heads
  • Enhanced intake valves
  • Oversized heat exchangers

Before one can appreciate what the Hennessey engineers have done, we must first acknowledge the base specs. The pre-’H1000’ upgraded CT5-V Blackwing boasts impressive stats. Putting its 6.2-liter V-8 to work, the Blackwing makes a solid 668 horsepower and 659 pound-feet of torque and can reach 60 MPH in 3.5 seconds, comparable to the Corvette Stingray and BMW M5. With a choice of six-speed manual transmission or ten-speed automatic, the Blackwing boasts a top speed of over 205 MPH, a figure that undoubtedly makes it one of the fastest luxury sedans to date. The EPA reports 16 combined MPG, with the CT5-V Blackwing getting 13 city and 22 highway MPG – figures on par with its supercar competition.

Understanding the CT5-V Blackwing’s base specs allows us to realize the true skill and talent of the Hennessey engineering team, as they took an impressive, and fast, luxury sedan, and true to their motto, made it faster. But how much faster? For starters, the recorded top speed of 205 MPH fell short of that of the ‘H1000’ upgraded Blackwing, which is proof enough of the insane bump in performance, but it doesn’t stop there. Taking into account the upgrades that went into the Blackwing, as well as its impressive base features, the ‘H1000’ is an incredibly unique machine, visually and mechanically, as the ‘H1000’ reportedly crushes its competition, Audi and Porsche.
