Ever wondered if manual transmission provides better fuel consumption than automatic transmission? Many of us research numbers as part of our decision making before purchasing a car. What we might not realize is that the EPA’s number reports are an estimate based on the manufacturer’s testing.
We’ve read a few stories on “calculations error” from manufacturers and such, which provided false numbers. In the “real-world” testing, the numbers are closer for the everyday driver. Especially when it comes to the city and mixed driving numbers. Weirdly enough, the highway numbers are generally correct.
There are two (2) main elements that provide us more insights as for which transmission is better. One of them being the number of gears that a vehicle has and the second one being the lock up torque converter.
1- Number of gears
Commonly, automatic transmissions have between six (6) to nine (9) gears forward speed. We wouldn’t be surprised if the new norm will be up to eleven (11) speed automatics due to the international “gear race”. CTVs is one to also keep in mind, which stand for “continuously variable automatic transmission”. If you aren’t familiar with the concept, CTVs essentially use pulleys to continually adjust the gear ratio. Which in return, theoretically speaking, gives them an infinite number of gears. Due to the vast number of gears available, CTVs make it easier to find the most effective one and in return improves the mileage consumption of the vehicle. The fuel economy isn’t as effective for vehicle that don’t have as many gear options.
