Probably for the same reasons as above, whilst not directly stated in this article, the Americans are not a fan of diesels and never really have been. The Ford Ranger diesel is an awesome engine with limited issues, selling like hot cakes world-wide, matched to an F150 gearbox, but yet it won't even be offered there, in favour of a 2 litre turbo petro model, what the? Whatever the reason everyone buys 6 litre petrol powered V8 utes is likely the reason.
Also, the Volkswagon Diesel engine scandal hit the US very hard and they are very scared of buying diesels. They are worried about destroying the planet with emissions, so they don't buy diesels, they banned Kinder Surprise eggs for kids because they could choke on the small toys inside, but yet you can still buy an AK47. Go figure!
