"Gasoline boosted engines have the same abilities but require priemum gas."
Not necessarily. A BMW 3 Series is yes, a Hyundai Sonata is no.
"Look at the trucks used to pull heavy loads, 18 wheelers, construction trucks, farm trucks, etc. They are turbo diesels, period. Why? Mountains of torque with no,worries about pinging (pre-detonation) that will destroy a gas engine."
Huh? There are advantages and disadvantages of engines. Gas engines don't 'ping' with the appropriate octane rating.
"Torque" is just one of Many features of an engine and not important in and of itself. How much work or pulling power of an engine whether gas, diesel, rotary, 4 stroke, 2 stroke, electric is measured in Horsepower.
A 325 hp Chevrolet Express van class b rv will run off and leave a turbo diesel Sprinter class b in a drag race because it has considerably more horsepower, that simple. But if going up a long long steep mountain highway, the Sprinter will ultimately win out. Why? It is NOT Torque. The Express Van does not have the cooling system that will allow using the noticeably more horsepower long enough. Overcoming gravity going up the hill can be noticeable, but traveling 85 mph all day on flat ground is no big deal for the Express Van and after 100,000 miles the cost is less than the Sprinter.
There are many different advantages and disadvantages of a Sprinter vs Express Van with torque not even on my list.
