Depinde de fiecare, de cat de mult circula, de ce masini prefera, de preturi, de ... mult chestii.
Dar consuma mai putin.
Din linkul pus de mine, mai sus:
you can see that the Caterpillar engine produces 1,650 lb-ft of torque at 1200 rpm, which is 377 hp. At 5,600 rpm, the Mustang engine also makes 377 hp, but it only makes 354 lb-ft of torque. If you have read the article on gear ratios, you might be thinking of a way to help the Mustang engine produce the same 1,650 lb-ft of torque. If you put a gear reduction of 4.66:1 on the Mustang engine, the output speed would be (5,600/4.66 rpm) 1,200 rpm, and the torque would be (4.66 * 354 lb-ft) 1,650 lb-ft -- exactly the same as the big Caterpillar engine.
Deci te joci la cutie si un diesel de 12.000cmc are acelasi cuplu cu un benzinar turbo de 4.600cmc.
Get it?
