Car Motor Curves with manual or auto trasmission

Short results

  • manual transmittion add 1.37wt+0.356carb^2 more Miles per gallon and subtracts -0.212cyl-1.76carb-1.72*wt^2 in average than cars with automatic tranmission
  • if you are choosing a car less than 2.2 tn of weight (and 4 cyl, 150 hp, 200 cu.in. engine, 4 forward gears and 4 carb) is better to take a car with automatic transmission

Thank you!
