Automatic Transmisiion - Manual Gearbox Comparison

Automatic Vs Manual Comparison
Automatic transmission or gearbox was once considered a feature of luxury cars only. But several cars are now available with the automatic transmission. Several car buyers are opting for cars with the automatic gearbox without considering its pros and cons. There are some buyers who have not even test driven a car with automatic transmission. So Drivespark brings to you a small comparison between the familiar manual transmission and the automatic gearbox.

A gearbox is the tool that transmits the engines torque to the wheels of a vehicle.. The gearbox as the name suggests has several wheels with each wheel indicating a gear. The gears in the gear box is shifted by using a clutch. A manual gearbox is a type of gearbox where gears are shifted by hand using a gear lever in cars and using a hand lever in motorcycles.

Gears determine the amount of power needed to accelerate a vehicle. While lower gears have more power and hence improve acceleration, higher gears sustain the speed for a longer duration while reducing fuel consumption. That is the reason why we need to down shift a gear when we need to accelerate quickly.

An automatic transmission is a gearbox that shifts through gears automatically whenever the engine's rpm reaches a specific rate. The automatic transmission can both up shift and down shift on itself. The advantage of the automatic transmission is the you need not worry about pressing the clutch every time you need to change gears. Further all your feet need to do when driving a car with automatic transmission is to control the accelerator and brakes.

  • One needs to choose manual or automatic transmissions for their cars carefully. There are several advantages and disadvantages for both transmissions and we have lifted some of them here.
  • While a manual gearbox requires you to use your limbs continuously while driving, it will also help in controlling your car's speed too. Further you can increase your car's acceleration whenever you need to make an overtaking maneuver.
  • The Automatic transmission simplifies your driving as you do not have to use the clutch and gear lever. It is very easy to use and driving is comfortable when on the highway.
  • The manual gearbox tends to be more fuel efficient than the automatic. Automatic transmissions consume more fuel during stop start city traffic as it will continuously be in lower gears which require higher amounts of fuel. This apart automatic transmission offers a more comfortable drive.
  • If you are new to driving, an automatic transmission will definitely help you. But be aware of the cost of having it. The cast of a car with a manual gearbox is comparatively lower than one with an automatic transmission. While this is a one time cost, the running costs of a car with automatic gearbox is higher due to higher fuel consumption.
  • An automatic transmission can provide you optimum fuel economy on long drives only. If you are someone who travel between cities that it is ideal but if you happen to drive short distances within a city the manual gearbox will be a better option.
