With 420 horsepower and 455 pound-feet of torque on tap, the 2015 Cadillac Escalade is one of the most powerful luxury SUVs on the market. However, we’re aware that some drivers, would be happier with more ponies sent to the wheels. Those fellows have the option of supercharging the 6.2-liter V-8 with help from Hennessey Performance and its HPE550 upgrade.
The update adds many performance parts to the engine, including a high-flow intercooling system, gaskets and other hardware. But, more importantly, it takes its output up to a whopping 552 horsepower and 565 pound-feet of torque. That’s enough to push it from naught to 60 mph in about 4.9 seconds, nearly a two-second improvement over the standard Escalade. Needless to say, it should keep most power-addicted SUV drivers pretty happy.
We might have to wait a while longer to see one of these beefed-up Escalades in action, but in the meantime, Hennessey Performance has release some dyno footage with the SUV revved to its limit. If you need your daily dose of supercharger whine, you’ve come to the right place. Hit the play button above and pump up the volume.
