Hennessey Cadillac CTS-V V1000 Twin-Turbo

Sometimes, enough is just never enough. To most, 550 horsepower in the Cadillac CTS-V Coupe is considered extremely fast. Hennessey Automotive begs to differ though, always pushing the boundaries of automotive insanity. But hey, insanity can be a lot of fun huh? Especially on a track.

Now, the company is releasing a new Cadillac Hennessey V1000 Twin Turbo CTS-V Coupe. This car comes on the heels of V700 upgrade that was previously introduced. The V1000 takes that up a notch to an eye-popping 1,000 horsepower. Talk about fast! The V-8 is 427 cubic inches in capacity, and as its name implies, is fed by twin turbochargers.

To make all that power, the LS7 V-8 has been beefed up with connecting rods and a crank made from forged steel, forged low-compression pistons, and ARP main studs and head bolts. When you’re pushing nearly double the amount of original horsepower though, changes must be made all around.

As such the manual transmission has been upgraded with a Centerforce Dual Friction Clutch and the automatic unit with a Performance Build & Torque Converter Upgrade. 0-60 arrives in 3.5 seconds, and the 1/4 mile in 10.9 at 136 mph. To bring the car to a halt, new 15-inch ceramic brakes have been fitted.

The exterior is more hunkered down and supercar-like, thanks to a lowered suspension (by 1 inch) and CarbonAero wide body kit. To save weight and make a change in appearance the CTS-V V1000 also gains front fenders, an extractor hood, rear diffuser and rear fended flares all made from carbon fiber.

General Motors test driver John Heinricy re-tuned the CTS-V’s standard Magnetic Ride Control (MRC) suspension. As a bonus, buyers of the car will get a day’s driving experience with Henricy. That will come at a steep price of entry, we’re sure. Only 12 copies of the V1000 are slated to be built – at a price yet to be announced.
