To improve breathing, the cylinder heads have been ported, and they’ve also received new, improved valve springs, retainers, lifters, pushrods, and valves on both the exhaust and intake sides. Elsewhere, the stock catalytic converters have been replaced by high-flow units so that the cops don’t give you grief. Actually, they might anyway – even a stock Escalade-V’s volume is unholy.
Elsewhere, the SUV benefits from an ECU tune (obviously) and a smattering of new badges, including a serialized plaque under the hood, but that’s as far it goes. The Escalade-V isn’t exactly a sleeper, but this restraint shown in the cosmetic department will surely help catch a few Hellcat owners unawares.
