Hennessey Performance has published a video showing the powerful 2015 Cadillac Escalade fitted with HPE550 power package doing several dyno runs. It is interesting that the tuned version is only RWD (rear-wheel drive), which is very strange for such enormous vehicle.

The SUV is 5,179 mm long, 2,045 mm wide, 1,890 mm tall with a wheelbase of 2,946 mm. The curb weight is 2,541 kg (5,602 lbs). The 2015 Escalade rolls big 20" alloy wheels fitted with 275/55 R20 tires providing good comfort.

The engine is a 6.2 liter supercharged V8 boosted to 552HP (406 kW) at 5,500RPM and 763Nm (565 lb-ft) of torque at 4,200RPM. This is an increase of 126HP and 139Nm. The result is thanks to a number of upgrades including a new high-flow supercharger system; high flow intercooling system; HPE engine management calibration; all necessary gaskets, fluids and hardware; professional installation; dyno tuning and road testing; serial-numbered dash plaque; serial-numbered engine plaque; Hennessey badging; HPE550 Supercharged badging; Hennessey embroidered floormats and a 3-year or 36,000 mile limited warranty.

The 2015 Escalade is priced from $71,695 and the price for the performance package is available upon request.
