What Does B Stand For In A Car? - Vehicle Freak

Owning a car can be a learning curve for even the most avid car collector. There are many letters and abbreviations that you need to become accustomed to before driving.

Due to rising fuel costs and awareness of the environmental damage that cars contribute to, Hybrid cars are becoming more popular. Hybrid cars are known for their economical features with the ability to switch to an electric transmission.

If you have already purchased or are thinking of purchasing a Hybrid vehicle then you will find that these cars have letters on the gearstick. But what do these letters mean? More specifically, “What Does B Stand for in a Car?”

The B is found on the gear shift of a car and should be used when on a long downhill stretch as it will increase the engine drag and help to slow the vehicle down.

What Does B Stand for in a Car?

Firstly the ‘B’ gear can act as a low gear. Holding your break for a long period of time can cause wear and tear on the brakes of your car.

That is when the B gear can come in handy. This gear is present to help your car maintain a slower speed. It is responsible for increasing the engine drag and allows your car to keep a steady speed.

Is This the Same for Hybrid Cars?

You may not be shocked to learn that ‘B’ stands for brake in hybrid cars. Now don’t get confused shifting into the ‘b’ position won’t stop your car but it will in fact slow the engine and work alongside the brakes. As mentioned this gear creates a drag.

In hybrid vehicles, this works brilliantly because it causes kinetic friction energy which can help to keep the battery charged.

Sounds pretty cool when you think that this gear is not only responsible for helping you control your speed downhill but it is also a self-charging dream that helps to reduce excess wear on your brakes.

What About the B Gear in an Automatic Transmission?

Automatic cars have a totally different gear shift from manual cars. Typically the gears read P (park), R (reverse), N (neutral), D (drive), and L (low gear).

It is here that you may come across the B function and in many cars it replaces the L. It is important to note that both B and L have similar functions but the main difference is that the B mode can apply the brake.

When Is it Safe to Use B Mode?

There is nothing more stressful than not being confident when changing gears. Using the B mode acts in the same way as if you were to change to a lower gear in a manual transmission.

As mentioned, you tend to break for longer periods if you were to travel downward at a steep gradient, this causes unnecessary wear and tear on your braking system and could damage the brakes causing their life span to shorten and leaving you out of pocket quicker.

Holding the brake pedal for a longer period of time can lead to complete brake failure which is never something you want when on the road!

To prevent this in a manual car the best advice is to switch to a lower gear so the engine can slow itself down and switch to the B gear acts in the same way. It is important that you apply the brake to slow the engine before switching gear or you could end up with a violent jerking as the engine slows.

It is important to understand that there are times when using the B mode isn’t a practical solution on your journey.

If you are on a highway maintaining a good speed then switching to B mode could be dangerous as it will slow your engine, something that could surprise other road users and could cause a collision.

If you are thinking about using the B gear to recharge your battery then remember this only works when traveling downhill. Using the B gear when on a straight road will essentially waste charge and drain the battery.

Shifting Gear Properly

After looking at why we would need to shift to the B gear it is only common sense to realize that the best way to shift gears is from D to B. If you are driving and wish for the engine to help slow you down then the B gear is the answer.

Once you have successfully shifted to the B gear you can then choose the P or parking gear. If this is making your head spin please don’t panic as automatic transmissions will not let you change into the wrong gear. This is to prevent damage and keep you and other drivers safe on the road.

Switching from D to B will create your engine to roar. This is perfectly normal as the car has been shifted to the lower speed gear and the engine is working to slow you down to a safe cruising speed without the need for pressing the brake.

Getting the Most out of Your Hybrid

To get the best performance from your hybrid car there are a few factors that you should be aware of. Hybrid cars are super sensitive so it is important that we eradicate any bad habits when driving to prevent any damage.

Take a look at a few features I have found for you to get the most out of your Hybrid.

Best Way to Be Economical in a Hybrid

All Hybrid vehicles have something called an EV Mode. Using this mode allows the car to run off the battery. You should only use this mode when traveling short distances.

The best time to use EV mode is if you are moving out of a parking lot. It is important to note that your car will have significantly less power in this mode.

The next function you should be aware of is the eco mode. Using the Eco mode makes the gas pedal less effective. The best way to use this function is when you are traveling on highways and at a steady speed.

Eco mode has no impact on your speed or your engine it simply prevents your speed from increasing while stepping on the gas pedal. This in turn has better economical desires as you won’t be burning fuel when it is unnecessary.

Essentially, this mode is to teach us that pushing the gas pedal to the floor when traveling on the highway only burns our fuel quicker.

We probably don’t think about when we are braking. We have all learned that the brake pedal will stop us from plowing into traffic or obstructions in the road. Surely this pedal is there to keep us safe right?

Well, it is recommended that braking in a harsh manner can actually damage our engine and in turn cause our brakes to fail. The best way to slow down is to release the gas pedal before applying gentle pressure to the brakes.

Of course, there will be some days where you have no choice, and slamming on the brakes will be your only choice but where possible it is important to understand there are different ways to slow your engine down before applying pressure to the braking system.

FAQs

What is the B gear?

The B gear stands for “brake.” In the B position the car brakes with the electric motor helping your hybrid battery to charge.

What is DS in automatic?

DS stands for the direct shift. This means that your car has a dual-clutch gearbox allowing for both manual and automatic transmissions.

Should I drive in D or B?

Driving in B mode is great if you are traveling the inner city and are using your brake more often. It is also beneficial to maintain your speed when traveling downhill. If you are on a freeway and traveling at a constant speed then selecting the D gear will be more efficient.

What does N mean in car gear?

N is NEUTRAL. Using neutral means that your car is in a free-spinning mode. There are no gears engaged meaning you have less control over your car. The N setting is only usually used if you need to tow your car or push it after breaking down.

Can you shift from D to B while driving?

It is ok to shift between D and B or B and D while driving. As all, you are really changing is the computer program for regeneration. In B you will have more battery recharge but no cruise control.

Conclusion

It is important to remember that the B gear can appear as the letter L but essentially they have the same functions and should only be used when you need to slow down. The most beneficial time to use the B gear is if you are traveling on a steep downhill gradient.

Making the most out of the B gear will help you get more out of your car. It reacts alongside your brakes which prevents damage and lengthens their life span.

When put to good use the B gear also engages enough friction and drag on the engine to help charge your electric battery.
