Since 1991 Hennessey Performance Engineering (HPE) has been at the forefront of high performance automobile modification. Embellishing high-line vehicles from General Motors, Ford, Chrysler, Lexus, and Toyota, as well as building custom creations like the World record holding Venom GT, HPE has evolved into a state-of-the-art facility that includes the world’s first state accredited Tuner school, a 40,000-square foot workshop and showroom, and the Lonestar Motorsports Park with an International Hot Rod Association (IHRA) sanctioned quarter-mile dragstrip on 143-acres near Houston, Texas.
Providing a fantastic starting point from which HPE can begin, the 2016 Cadillac CTS-V hits the streets with a 6.2-liter V8 that makes 640-horsepower and has a projected top speed of 200 mph. HPE plans to pick up where they left off with the last generation Caddy by producing the world’s fastest sedan: The Hennessey HPE1000 Twin Turbo CTS-V. “A couple of years ago, the State of Texas gave us the opportunity to test one of our specially tuned CTS-Vs – our VR1200 Twin Turbo coupe. It ran 221 mph (356 km/h) on State Highway 130, near the Circuit of the Americas”, said company founder, John Hennessey. “It was still pulling on when we ran out of road. I believe that our 2016 Twin Turbo CTS-V will have a top speed approaching 240 mph (386 km/h)”. Hennessey plans to produce a limited run of only 24-units for the 2016 model year.
Engine modifications will include removal of the factory installed supercharger. It will be replaced by a specially designed engine intake manifold and fed by twin-ball-bearing turbochargers with stainless-steel inlet piping, dual wastegates, electronic boost controller, an air-to-air intercooler, and dual K&N air filters.
Providing sufficient fuel for the increased air induction involves a fuel injector and fuel pump upgrades. Engine temperature is decreased by installing a 160-degree thermostat and a stainless-steel exhaust system dispenses spent gases with little restriction. The drastically modified engine is tamed using HPE Engine Management software. The HPE 1000 is expected to have an electronically controlled top-speed of 240 mph.
Internal engine upgrades incorporate a forged steel crankshaft and forged steel rods, a custom high duration and lift HPE camshaft, and specially ported cylinder heads. Hennessey offers a 1-year/12,000-mile warranty.
Bringing the Cadillac to a halt from Formula 1 speeds will be accomplished using oversize carbon-ceramic brakes with vented rotors. Larger wheels and tires (Hennessey Monoblock H10 wheels are available) will be accommodated by outfitting the HPE 1000 with a widebody upgrade that will feature custom Hennessey badging.
Interior embellishments include premium Hennessey floor mats, Hennessey embroidered headrests, as well as serial numbered dash and engine plaques. “I’ve owned and driven several Cadillac CTS-Vs over the past 5 years”, said John. “I love the practicality and the ease of driving these cars every day. They are also a great platform from which we can create our own special 4-door supercar.”
