The latest CTS-V isn't even on sale yet but should be a powerhouse straight from the factory. Under its carbon fiber hood is a 6.2-liter supercharged LT4 V8 with 640 horsepower and 630 pound-feet of torque that makes the sedan capable of a 200-mile-per-hour top speed. Hennessey's take ditches the blower in favor of two turbos to feed air to the engine. To cope with the extra power, the mill gets upgrades like forged aluminum pistons and forged steel parts for the rods and crankshaft, and transmission upgrades are also necessary to make it all work. Buyers can even spec things like carbon-ceramic brakes and a widebody kit to allow for bigger tires.
The crazy numbers are leading to some big performance claims from company founder John Hennessey. "I believe that our 2016 Twin Turbo CTS-V will have a top speed approaching 240 mph," he said in the Caddy's announcement.
Hennessey is building just 24 of these 1,000-horsepower sedans for the 2016 model year. However, for those that want to keep the supercharger under the hood, the company is also offering upgrades with 750 hp and 800 hp for the CTS-V too. All of them sound absolutely ridiculous in an utterly fantastic way.
Texas Tuner Plans to Build World's Fastest 4-Door Sedan
Sealy, Texas-When the next generation Cadillac CTS-V hits the streets later this year, it will have 640+ hp and a top speed of nearly 200 mph. To the team at Hennessey Performance Engineering (HPE), this is a good starting point. The company plans to pick-up where they left off with the last gen CTS-V by producing the world's fastest 4-door 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 offer a limited run of only 24 units for the 2016 model year. Powered by a strengthened 6.2L V8 engine, the company will remove the factory supercharger and will add twin turbos for increased power and performance. HPE also plans to offer a full compliment of performance upgrades including carbon-ceramic brakes, larger wheels and tires, widebody upgrade allowing for wider tires as well as custom interior upgrades.
"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."
HPE also plans to offer a wide array of performance upgrades for the 2016 CTS-V. This will include engine packages that deliver 750-800 hp from the factory supercharged V8 engine.
