GMC Yukon
Denali by Hennessey Performance
Hennessey
Performance have worked their magic once again, this time on the 2015-2016
Yukon Denali.
Available exclusively on models equipped with the 6.2-liter V8,
the HPE650 package has increased the unit's output from the standard 420 HP and 624 Nm of torque to no less than 650 HP at 5,500 rpm and 892 Nm of torque at 4,200 rpm. This translates into a zero to sixty sprint in
4.5 seconds and a quarter mile run in 12.9 seconds, with an exit speed of 171 km/h.
Squeezing the
extra 230 HP from the GMC Yukon Denali's powertrain was achieved by adding a
2.9-liter supercharger system, high flow intercooler, stainless steel cat-back
exhaust and HPE engine management calibration followed by dyno tuning and road
testing.
All Yukons featuring this upgrade will also benefit from the serial
number dash and engine plaques and "HPE650", "Supercharged"
and "Hennessey" exterior badges.
On top of the
package one can opt for the Hennessey Wheel Upgrade with 22-inch rims, and
Brembo 15-inch front brake calipers. The tuner's aftermarket features are
coming with a 3-year / 36,000 miles warranty, but no pricing
details have been released yet.
