The new F-150's maximums will without a doubt be attained to with the V8 and likely 2WD for the tow rating. Regardless i'm experiencing difficulty envisioning a truck conveying 3,300 pounds in the bunk, yet trust it or not the 2014 F-150, in standard taxicab 2WD trim with the 3.5 EcoBoost, is now up to 3,100 pounds payload. The V8 gets an additional 20 pounds on top of that. Both oblige an "overwhelming obligation payload bundle."
A 2015 Chevy Silverado 1500 with a 6.2 V8 and "Max Trailering Package" is close behind with a 12,000 pound tow rating. The Chevy's payload rating is around 1,700 pounds in that arrangement, maxing at 1,820 with a 5.3 V8 in 4WD.
A 2015 Ram 1500 with a 5.7 HEMI tops out at 9,250 pounds towing or 1,635 pounds payload.
Portage is staying silent on efficiency upgrades, enigmatically saying the 2015 truck will get "no less than 5 percent and as much as 20 percent higher gas mileage than today's truck, contingent upon the model." There are an excess of designs to make a precise supposition.
