Payload makes me drool a little.
Overseas buyers seem to have much higher expectations than we do for payload. Payload figures for the overseas version of the Ranger run from 1,300 to 1,500 kg. That's 2,981 - 3,300 lbs for us non-metric types. They're in what we would consider the 3/4 ton range in the US. Well above the rating for the same year F150 or Ram Power Wagon.
I read an article a few yeas ago comparing new "utes" (Hilux, Navarra, Ranger, Triton, DMax, etc...) in Australia. The authors seemed to expect everything to be somewhere around the 1,000 kg (2,200 lb) mark as an informal standard. At the time, most half ton trucks in the US, (F150, Silverado, RAM 1500) couldn't compete with that. US half-tons seem to be upping their game in the last few years, especially Ford, but even now a new Power Wagon (allegedly a 3/4 ton truck, but with only a 1,470 lb payload), isn't rated to carry even half of what those little guys do.
Imagine yourself grabbing the keys to the Ranger because the Power Wagon isn't capable of hauling the load of bricks you need to pick up.
How do you calculate payload anyway? I have always thought that it should be the lowest capacity in the envelope defined by tires, suspension, wheel bearings, brakes, and drive train minus the curb weight. But I have no idea how they actually do it. I see people augmenting their suspension to increase payload, and while it can certainly make the truck drive better with a load, does it really change the numbers if the weak link in the manufacturer's calculation was braking or wheel bearings?
I suspect there may be some differences in how they calculate payload, but I don't know for sure. Some of it has to be marketing. Until a few years ago, there was no mandated standard for calculating tow ratings. That's why my 1972 CJ-5 is rated to tow 5,000 lbs, but a new 2-door JL with double the curb weight, double the horsepower, better braking, longer wheelbase, and a boxed frame is rated for 2,000 lbs. Even the 4-door, which is bigger than a 70's Grand Wagoneer in every way, is only rated for 3,500.
Something tells me the US version of the Ranger is going to show payloads a lot more similar to the Colorado and Taco than what it gets overseas.
Interesting Payload Specs from around the internet, mostly gas motors, configured the way I was interest in at the time. other configurations are possible, but if you want to haul something. Look for a Ford. Sorry for the obvious gap, but it really never occurred to me to even look at Chevys other than the Colorado diesel.
