The ink is still drying on the all-new 2015 Cadillac Escalade sales brochures, but that hasn't stopped Texas-based Hennessey Performance (HPE) from leaping out of the gate with its own high-performance variant. In stock form, the big fourth-generation Cadillac flagship arrives with a new small block naturally aspirated 6.2-liter Ecotec3 V8 delivering 420 horsepower and 460 pound-feet of torque. Fresh out of the showroom, the 5,900-pound SUV will sprint to 60 mph in 5.9 seconds.

While that is plenty fast for some owners, others don't want to be shamed by a 550 horsepower Mercedes-Benz GL63 AMG or a 510 horsepower Land Rover Range Rover Sport - both will leave the stock Escalade at a stoplight.

The team at HPE has come to the rescue with its HPE550 supercharger upgrade, which includes a belt-driven supercharger, air-to-water intercooler, recalibrated engine management software and a three-year/36,000 mile powertrain warranty. With 6 psi of boost, the direct-injected 6.2-liter is tuned to deliver an impressive 557 horsepower and 542 pound-feet of torque - gains of 32 percent and 18 percent, respectively, over stock. Although HPE isn't releasing performance figures as of yet, our math says that should be enough power to put the two Europeans in the Cadillac's rearview mirror. The company also offers a set of 20-inch lightweight H10 forged monoblock wheels, to further improve performance.

The HPE550 upgrade costs $15,950 installed. If that fits your budget, and satisfies your ego, find more detail from Hennessey in the press release, below.

Hennessey to Offer 557 HP Supercharged Engine Upgrade for 2015 Cadillac Escalade
Texas-tuned Caddy takes aim at AMG & Range Rover high-performance SUVs

Sealy, Texas-While Cadillac has reinvented the Escalade, the preferred mount of rock stars, pro athletes and Hollywood's red carpet elite, Hennessey Performance (HPE) has put in overtime developing a supercharger upgrade for its new 6.2-liter direct-injected V8 engine. It's all the better for sneaking up on the unsuspecting Mercedes GL63 AMG or Range Rover Sport...that is, until the roar of the exhaust and subtle Hennessey branding give you away.

"Our HPE550 Supercharged Escalade is the perfect balance of attitude, performance and luxury. It's fast and versatile, and proudly American," said Hennessey CEO and partner Don Goldman.

The HPE550 package serves up a stout 557 bhp and 542 lb-ft of torque from the belt-driven supercharger producing 6 psi of boost pressure, gains of 32 percent and 18 percent, respectively, over stock. Extra power is nothing without reliability, so an air-to-water intercooler system keeps charge temperatures low, and Hennessey's recalibrated engine management computer optimizes the air/fuel ratio throughout the rev range. HPE is proud to back its HPE550 upgrade ($15,950 installed) with a 3 year/36,000 mile powertrain warranty.

Further upgrades available include a set of lightweight Hennessey H10 forged monoblock wheels ($6950), whose 20-in. diameter accepts the Escalade's factory tires. The H10 wheels' reduced rotating mass allows even more power to reach the tires-less energy spent accelerating the wheel means more energy pushing the vehicle down the road.

While the Escalade might be the most glamorous application for our HPE550 upgrade, it's also available for other GM vehicles with the 6.2-liter DI V8. The list includes the 2015 GMC Yukon Denali, 2014-2015 GMC Sierra trucks, and 2014-2015 Chevrolet Silverado trucks. Complete turn-key Hennessey HPE550 vehicles can be ordered directly through our authorized dealers, including Sewell and Hendrick.

"The new 2015 Cadillac Escalade is the perfect platform for a Hennessey infusion of horsepower," said founder and president John Hennessey. "It's luxurious, spacious and cries out for personalization and more performance. I plan on making this our next family hauler for our five teenagers and four Labrador Retrievers."

      If Cadillac offered this engine upgrade along with a brake upgrade an optional ceramic brakes in a V sport with a limited run of 2,000 vehicles a year I bet they would sell out right away.

      Anybody else find it totally stupid when you upgrade the power but dont add the additional breaking power needed.

        Don't you find it totally stupid when people don't know the difference between "break" and "brake"?

          Well, to be fair, "break" is a word synonymous with GM.

        Hennessy operate with everything for sale piecemeal. You pay for every line item individually with very few exceptions. They are not like many other tuning companies like roush for example who has everything in "stage" 1,2,3, ect. packages.

      Still looks like it was left behind in the year 2000.

      I'd take a Cayenne Turbo for my $100k: 500/516 and room to go up. Plus I get build quality and styling, not a 2001 brick.

        Then you will be settling for less vehicle just to have the Porsche badge. Go on the Porsche configuration and price a Cayenne Turbo out with the same options as the Caddy. Good luck finding one for 100k

        I just checked A base Turbo (not the Turbo S) with no extra options is $110,000 MSRP. Cayenne buyers(SUV car based platform) and Escalade buyers(truck platform) don't usually cross shop each other as they do not compete.

      Now it's a much more powerful and even MORE overpriced turd.

      The Yukon Denali still looks less like a drug dealer/porn star vehicle and has almost as many features and a lower price. They should supercharge that.
