This is a good point. But remember one other thing. In 2005, many of us were driving around in 3500 lb cars. This thing can weigh north of 5000 lbs.I always enjoy people trying to reason that the 2.7L is needed because they need to be able to merge onto the freeway and the 2.3L won't be enough. Do they think every vehicle pre-2005 when 300hp was exceedingly rare on anything outside of supercars and muscle cars just crashes and burns every time it has to get up to highway speeds on a half mile long on-ramp?
My old Passat with a 1.8T made 150 hp stock and 200 with an APR tune. It weighed 3200 lbs.
My next car a 2004 Subaru STi, made ~400 hp with a tune and downpipes and weighed 3300 lbs.
Put another way.
A 5000 lb vehicle with 300 hp has the same power to weight ratio as a
3000 lb car with 180 hp.
But even then, I totally agree that the 4 will be more than adequate for 99% of the buyers of the bronco.
Like mosts of the options that most of us get. The V6 is a WANT. Not a Need.
