^^Yet, they're not explaining the real reason WHY it won't do such a thing. Well, for FOUR reasons.
The Shelby GT500's engine is the only supercharged V8 left by Ford, and that makes 78 hp more than in the Escalade-V.
They're spending their development costs on something better and not create a cash-cow in what will make a boring segment. Instead, they're creating something unique - don't miss out on the FORD F-150 RAPTOR R! (Basically, still a Navigator but in truck form and with a Blue Oval badge)
Stated above, PLUS why isn't Chevy or GMC building a Raptor rival?? You can't expect something in return if you don't do it! Life is a TWO-WAY street! Do unto others as you do unto yourself! Cadillac doesn't even build an XT6-V or XT6 Hybrid to rival an Aviator GT PHEV!
Even if they WERE to hybridize the Navigator's 3.5TT V6, it would still BLOW the Escalade-V out of the water!!!
From my writing on the Escalade-V page:
All this power and it's still barely faster on a dragstrip than the twin-turbocharged, two-wheel-drive Lincoln Navigator. It's a clear disadvantage of supercharging versus turbocharging. 1/4-mile in 12.7 seconds at 110 mph for the Escalade-V versus 13.1 seconds at 104 for the Navigator! At least it comes with the fun factor that the Navigator will never have!
Contrary to popular belief, it's not a fighter in the performance SUV segment. But it's still a BEAST in the underdog non-European full-size class, and the upcoming Lexus LX750h F Sport will play swords with this steroidized Yoda in the next Star Wars film!
To be honest, Cadillac's "V" version is just an LT4 version of the outgoing L87 model which was significantly lacking in performance compared to the EcoBoost Navigator, as well as the Hemi and Hurricane Grand Wagoneer models. Unlike with the German SUVs, there have been little to no physical exterior changes to make the Cadillac better on the track.
Cadillac's Escalade-V isn't a GLS63 or XB7 rival, don't think of it as that even with this extra power. It's only become a thing because Cadillac wants to remain King of the Hill in the segment.
If you recalibrate the Navigator with an ECU or even some OEM Ford Performance-approved parts that'll give you between 20-50% +power. At 660 hp (and 610 lb-ft of torque from a very low rpm) with stock internals you can expect it to beat an Escalade-V by almost a whole second in the quartermile! You're not gonna get any better than 820 hp and 750 lb-ft of torque in an Escalade-V with stock internals.
440 hp out of a 3.5TT = 125hp/L [vs] 682 hp out of a 6.2SC = 110hp/L
equivalent to 62hp/L (3.5 x2.0 = 7.0 na) for the Lincoln and 77hp/L for the Cadillac (6.2 +2.6 supercharger = 8.8 na), neither of which are particularly good figures in today's world.
510 lb/ft out of a 7.0L engine = 72tq/L na or 145tq/L turbo (Lincoln)
652 lb/ft out of an 8.8L engine = 74tq/L na or 105tq/L supercharged (Cadillac)
Even the Lincoln Aviator GT PHEV with the 3.0TT V6 is close to the Escalade-V in 0-60, it does that sprint in 4.3-4.5s consistently. The Escalade-V will do it in 4.2-4.4s.
