I think it would be cool if FPV did an Explorer with the Boss 290 in it, and better handling maybe probably with air suspension so u can raise and lower it for the best on-road and off-road experience and a sporier interior based on the Limited. Brembo brakes would be good too!
It would sit nicely above the FPV Territory Turbo and unrealistically below an FPV Expedition with the F150 Lightning engine
But seriously FPV Explorer with Boss 290 would do well i am sure, and would go as hard as a BMW X5 4.8
It would also put HSV Avalanche in its place. If anyone is gonna reply saying the 5.4 wont fit, Saleen made a 351 Explorer in the old model, and the 4.6 fits with ease, so i cant see why it wouldnt.
