Toyota gasoline engines aren’t heads and shoulders above the competition in terms of performance, just in being trouble fee and maintenance friendly.
But yes, we don’t have widespread adoption of diesel engines in the States. So I wouldn’t know.
It isn't just diesel engines. Government laws and regulations create 'parallel' worlds of vehicles all around the world. The automobile world seen from North American eyes is like a bubble distortion.
The Ford Everest and Turbo diesel Ford Rangers with BiTurbo and Powerstroke engines compete with the Hilux and not Tacomas. What I know about Tacomas and 4Runners they have decent ride not unlike the Hiluxes which are straight out hardcore. Other Toyota pickups we don't see in the US market is the 79 series Land Cruiser which amounts to a Land Cruiser ala Jeep Gladiator style, and the cab forward Lite Ace and HiAce pickups used in the Japanese and Asian domestic markets. You can get a brand new Lite Ace for as low as $12k USD. It's also of note that the Hilux competes directly with the Lite Ace and HiAce in certain markets. The Land Cruiser Pickup is the vehicle most notorious for Middle East technicals, like in ISIS. They're powered by a turbodiesel V8 not introduced to the US market. Given the high price of these vehicles, easily around the US$80k range, the US State Department wonders how insurgents can afford these vehicles.
I have been studying about non US market pickups like the Mitsubishi Strada, Nissan Navara (the true Hardbody and Frontier successor not like the one you have in the US now), the Isuzu D-Max and the VW Amarok. These vehicles also have ladder in frame SUV equivalents which is interesting because the US market has been missing the Montero Sport and Nissan X-Terra (now just the Terra) for so long.
