torque + horse = energy released by the engine.
assume no energy lost due to heat released due to speed - in 10 min on 3th gear then 10 min on 6th gear you have more torque in the first and more horses on the second. during this time on 3th and 6th gear, the gasoline consumption are the same. on the first, you can climb stiffer road, one the second you gain more speed on straight road reflected on MPG
