If you have 5 gears in your car, overdrive is the 5th gear while all lower gears are called drive. Overdrive only needs to be turned off when you are slowing or when you are going uphill as this is when you require more power to push up the vehicle. The only drawback of overdrive is that it does not let the vehicle reach its maximum speed. If the maximum speed of your car is mph, you can reach this speed with drive gears but you have to make a sacrifice with overdrive as it will not allow the car to go beyond a speed of mph.
While drive is ratio implying wheels are turning at exactly the same speed as the engine , overdrive is around 0. You thus achieve higher speeds with less noise of the engine with lesser consumption of gas with lower torque now available to you. This is bad news for acceleration or towing. This gear has a low ratio so it will work the same in an automatic car that it does in a manual car.
There is one main difference and that is in a manual car you have to select when to apply the overdrive gear. When you are driving an automatic car, the gar is activated by the ECU. This will decide for you when your car will be put in overdrive. As far as manual cars, the highest gear on the transmission is usually the overdrive gear because it is the lowest gear. The majority of cars have five total gears.
Some cars even have six or seven gears depending on the type and the manufacturer. Having more gears in a manual car means that you will have better fuel economy. For example, think about trucks and how many gears they have. Trucks have ten or eleven gears so they are able to conserve fuel easier. You are driving along the highway for hours at 70 mph.
If you turn on your overdrive, it will work like magic. This option helps take off so much pressure from the engine and it brings down the RPM. This will help you keep your engine in great shape and it will last for a longer period of time. Engines are incredibly expensive to repair and replace , so it is important to do whatever you can to keep it in the best shape.
It will not benefit your car to use it when you are driving at slower speeds or in stop and go traffic. When you need to downshift, the braking system is used.
If you are driving downhill, your braking system will be worked very hard because you have to continuously press the brake pedal. If your overdrive is on during this situation, it will keep your RPM above idle. A great rule of thumb is to only use overdrive when you are driving at high and consistent speeds. Are you wondering how this overdrive gear can benefit you while driving?
This unit consists of a gear that is electrically operated. This reduces wear and tear on the engine and saves on fuel. Overdrive will help you keep your engine in the best shape possible.
This only happens if you use it properly though. Overdrive should not be used at lower gears. This overdrive feature has become very common and popular gear in most cars. It will help you reduce fuel consumption while you are driving at high speeds.
Overdrive is a very simple concept and it is used in your everyday driving whether you know it or not. However, the more you know about this system the better off you will because you can use it to your advantage. You can use it to save on fuel costs and keep your engine in the best shape.

It brings the RPM of the engine down at a given road speed to facilitate better speed and fuel efficiency.
It also helps your car to provide the best performance in higher speed cruising. Usually, cars having this gear have a dedicated overdrive button. Switching it on means locking it out, not to engage it. When you push it, the transmission goes through all the gears and then limits the functioning within the rest of the gears. You should leave the OD switch on all the time for regular driving.
Your car will automatically shift into top gear if necessary, regardless of your selection. When you drive at more than 60mph 50mph in case of older vehicles , the RPM increases and the engine starts taking more and more strain. Turning on the OD will work like magic to take the pressure away from the engine and bring down the RPM.
