Hennessey’s Cadillac CTS-V Dips Into Hypercar Realm With 1,000 HP

While Cadillac is sending off the CTS-V with the Pedestal Edition, Hennessey is, once again, working on GM’s BMW M5 and Mercedes-AMG E63 fighter.

In the short video they released, they show the 1,000 hp (1,014 PS / 746 kW) and 966 lb-ft (1,310 Nm) tuned hyper sedan in action at the Lonestar Motorsports Park.

The stock CTS-V’s supercharged 6.2-liter V8 engine produces 640 hp (649 PS / 477 kW) and 630 lb-ft (855 Nm) of torque, sprints to 60 mph (96 km/h) in 3.7 seconds and maxes out at 200 mph (322 km/h).

Thanks to the upgrades performed in the engine compartment by Hennessey, this CTS-V is a heck of a lot quicker. It needs 2.9 seconds to hit 60 mph (96 km/h), and it can run the quarter mile in 10.5 seconds, at 135 mph (217 km/h).

The HPE1000 engine upgrade is available at the Texan tuner and suits all 2016-2018 Cadillac CTS-Vs. Besides the immense output produced by the engine, the package ensures dyno tuning and road testing of each model. The cars also come with special exterior badges and floor mats with Hennessey branding, as well as serial-numbered dash and engine plaques.

Hennessey says 93 octane fuel is needed for unleashing the full 1,000 hp, as using 91 octane gasoline will result in lower output numbers and, thus, inferior performance.

    This looks great, and specs sound impressive. I wish someone would do a head 2 head of these aftermarket turner sedans, obviously it would be a big undertaking but would make for a great video.

    Mine will roast the tires with no problem and it’s only stock. I can’t even imagine the effort it takes to put the power down on that monster.

  • You should ice that burn

    I wish GM wasn’t ceding the sedan market to Asia and Europe, one day a younger group of buyers will look at SUVs and Trucks and say “looks like what my uncool parents drive” and they won’t have a domestic sedan to call their own. I drive a 1st gen 5 spd CTS and it’s a great car, great handling, comfort, and almost 30 MPG, sure it’s not a V (I’d love one) but it’s been super reliable and fun to drive. (it’s never in the shop unless I schedule regular maintenance, can BMW or Benz drivers say that?)

      Unfortunately, the high demand for SUVs/CUVs is global and continues to grow. It is unbelievably expensive for automakers to develop an entirely new model or generation of an existing model. VW spends somewhere in the $1.5-$2 billion range for a new generation of the Golf. With sales of sedans declining, automakers have obviously conducted market research and determined that those billions of dollars are better spent elsewhere and/or new SUVs.

      I drive a 16′ S3 and will be looking at a Kia Stinger soon to replace it. I love sedans but I completely understand why SUVs have taken over and likewise with light duty pickup trucks. Thanks to modern drive-train technology, these larger vehicles are no longer penalized for their size. Many of them are downright quick even in lower specs and they still return relatively good fuel economy. Even if consumers don’t frequently need the additional space an SUV/pickup offers, it makes sense to have that extra space should one need it. These vehicles are competitively priced so buyers aren’t penalized there either. Regarding current pick-ups, they are on another level from pickups of just 10-15 years ago. In high specs, they are legitimate luxury cars with air ride suspension and every driving safety aid.

      I often need more interior space in my car and it is my only complaint about the S3. Its small size is great for the driving experience but its interior space is very limiting. While I will be looking at the Stinger, I will also be looking at the new RAM. I hope sedans continue to survive but I just don’t see it happening.

      Wow, you’re in the minority.

      I’ve you’ve got the 3.2 or 3.6, I’m very surprised you haven’t had timing set issues, or head gasket issues. Those motors were trash.

        The 3.2, No issues besides a small oil leak on one valve cover, while I had it opened up I put new plugs and coil packs in. Getting close to 200k on it and it runs like a top. I do change the oil religiously, which shows because that engine is clean enough to eat off of inside.
