When you downshift, you change to a lower gear when driving. So is downshifting bad? There will be people who are both for and against this driving technique. But in fact, the idea that engine braking/downshifting is bad for your car's engine is a myth. People believe that the mechanism would harm the engine and the drivetrain, but this is not always the case. In this article we will thoroughly discuss why downshifting is being done, why people question, “Is downshifting bad? And why it actually can’t be all that bad.
Is Downshifting Bad? But What Is it Exactly?
Downshifting is a skill you must master if you want to regulate your speed when driving. It's a mechanism known as engine braking, which involves slowing down a vehicle that's going at a high speed. Many people believe that downshifting causes harm to the engine.
You'd be driving at the same pace the whole time if you didn't downshift. The process of upshifting and downshifting is what makes driving exciting and enjoyable. When it comes to downshifting, it's a technique for slowing down a vehicle by lowering down the gear to a heavier one. Downshifting, when done correctly, is a procedure that results in the car running smoothly.
In manual transmission cars, where you have complete control, downshifting to slow down is a common practice. For example, suppose you're driving in 4th gear and suddenly remember you need to slow down a little. You shift to 3rd gear. Downshifting refers to the procedure you use to move into third gear.
Why is Downshifting Bad?
As mentioned before some experts still advise against downshifting. They have a different answer to the question, “is downshifting bad?” Some websites on driving still include downshifting as a driving habit to avoid when using a car with manual transmission.
Some experts expressed that using manual transmission to slow down a vehicle can be costly. The clutch disk that connects the engine to the transmission is made of the same material as the brake pads/shoes on your vehicle.
This clutch wears out slightly every time you turn. It is often more costly to repair a worn clutch than it is to replace brake pads, regardless of the car. Extreme downshifting will put the engine and transmission mounts under a lot of strain.
So which is better downshifting or braking? Downshifting (also known as engine braking) is common with drivers for two reasons: it's cool to drive like a smooth, skilled race car driver, and it saves money on brake wear and tear, as pedals, brake pads, discs, and rotors can be costly. Experts who advise against downshifting warn that downshifting makes both the engine and the transmission work harder, and you can end up spending more money on gas and transmission with this process.
Is Downshifting Bad? So Why is It Being Done?
Here are the reasons why drivers downshift:
- Downshifting is done when you'd like to slow down your travel pace. Simply taking the foot off the accelerator causes the car to slow down, the engine to rev lower, and the engine to rev outside of the range where it produces enough power. As a result, you step down to match the gear ratio to the new travel speed.
- You downshift when you want to use your engine as a brake. Normally, the car is powered by the engine. When you let go of the gas pedal, the car pushes the engine, which serves as a brake. Since the engine's braking power increases as the engine revs higher, you shift down to allow the engine to rev higher and develop more braking power.
- You downshift when you need more power. The majority of engines produce their maximum power at high revs. When traveling at highway speeds, you can normally use top gear and keep the engine revving at a low rate. As a result, there is less noise and less fuel consumption. The acceleration in the highest gear is very sluggish if you want to stomp on the accelerator.
The car accelerates much quicker if you change down a gear and stomp on the accelerator pedal. When driving up a hill, the same is true. You change down to get more power if the engine does not produce enough power to sustain speed when driving uphill (at higher engine revs).
Overall, downshifting is a useful strategy for smoothly turning curves, handling traffic, avoiding dangerous road conditions (such as potholes, snow, or ice), or simply slowing down without using the brake.
Although it is possible to coast to a stop in neutral, you can lose some control of the vehicle if it is not in gear. It's always easier to downshift when you slow if you know the stop is coming but remember you won't affect the car even if you don't.
Other Situations Where It’s Better to Downshift
- Driving Downhill
Engine braking/Downshifting is most often used to support the brakes when driving downhill. If you're driving down a long slope, you might feel compelled to “ride the brakes” to keep your speed under control. However, constant braking downhill has its drawbacks. To begin with, your brake pads will wear out faster.
Brake pads produce friction material that converts your vehicle's kinetic energy into friction, which slows and stops your vehicle. Over time, the friction content degrades. As a result, brake pad replacement is a necessary part of routine maintenance. However, excessive friction during downhill braking allows the brake pads to wear out more quickly. It also generates a great deal of heat, which can damage the brake system. Brake rotors can overheat and warp, and brake fluid can boil, causing problems in the device.
A condition known as “brake fade” may also develop. When you keep slamming on the brakes while driving down a slope, the brake system can no longer handle the heat. The effectiveness of the braking system, as well as your ability to slow down, decreases as the brakes heat up. In hilly areas, some roads have designated runaway truck lanes.
Moving downhill, the bigger the vehicle, the more difficult it is to brake. As a result, you can prefer to use engine braking, as many truckers do with their big rigs, to assist the brake system when going downhill.
- Driving on Muddy, Snowy and Slippery Roads
Slowing down in traffic and retaining power on muddy, snowy, or slippery roads are two other situations where engine braking can be beneficial. Why would you use engine braking in these situations? For starters, you can extend the life of your braking system. Additionally, since you are letting off the gas pedal, you will be able to save more money on gas. You will also stop locking up your tires by not putting too much pressure on the brakes, which will help you maintain better control in slippery situations.
Is Downshifting Bad? How Can You Do it Right?
Again, is downshifting bad? Yes, it can damage the engine and your car’s drivetrain but only when it is not done right. The following are the proper steps to take when downshifting a vehicle, and they must always be held in mind to minimize wear and tear.
- First, know your controls.
There are three components grouped in a line when you look at your car controls at your feet. The clutch is on the left, followed by a brake in the center, and finally the accelerator. The clutch, which comes in handy when downshifting, is the most critical of all the components.
- Second, know the process.
The only way to travel quickly is to shift gears as the car needs. Downshifting when going down mountains or slopes is also a great way to keep your vehicle's acceleration under control. All an individual does in this process is change to a higher gear to counteract the car's speed. It's not about putting all of your weight on the engine and clutch, but changing gears from low to high or vice versa on time is nothing more than a statistical blip.
So how do you know when it’s time to shift down? The engine will lag if the car is moving too slowly for the gear you are in. It could shake, rattle, or emit a low rumble, and it could even sound like the vehicle is about to stall. The tachometer can also inform you when it's time to shift down if it reads about 1 (or 1,000) RPM.
Without looking at the tachometer, How do you know when to downshift? You'll probably check the tachometer a lot when you first start driving a manual transmission, but as you get better at it, you'll learn how the vehicle feels when the gear is too low and won't need to. The low, rattling sound and stuttering feel of an engine lagging in a too-high gear will become familiar to you.
When Is It Time to Downshift?
The tachometer indicates when it's time to change gears. When the tachometer reads about 1 or 1,000 RPM, move down (and up at 3 or 3,000 RPM). The tachometer indicates when it's time to change gears. When the tachometer reads about 1 or 1,000 RPM, move down (and up at 3 or 3,000 RPM).
- Single-clutch downshift – the most common downshifting method
- Double-clutch downshift – If your car is old and doesn't have synchronizers, you'll need to double clutch. While double clutching is not needed in most cars, it is important to understand the difference and how to execute this downshift.
- Heel-toe downshift – In everyday driving, the heel-toe downshift is unnecessary. It is mostly used in race driving, such as circuit racing around corners, because it allows for smooth cornering. This is one of the most difficult and sophisticated downshifting techniques available.
Is Downshifting Bad? Words of Advice
Now that we have already discussed the benefits of downshifting and how to do it right, let us step back a little and know the instances when you should avoid downshifting or engine braking. So is downshifting bad? Here are the instances it can be.
As mentioned earlier, downshifting, also known as engine braking, is a helpful technique for reducing brake wear, maintaining vehicle stability, and safely descending hills. It's a common feature of manual transmissions. It can be used with automatic transmissions, but it has a lesser impact. However, caution should be exercised in using engine braking too forcefully.
As the vehicle slows down, a driver will normally change from a high gear to a lower gear to fully use engine braking. This procedure improves the technique's efficacy. But shifting at too high an engine speed (RPMs) or going into too low a gear, on the other hand, can put a lot of strain on the drivetrain, especially the clutch and transmission. Premature engine wear can also be caused by too much applied force from a sudden dramatic change. This is what other experts are worried about.
So when coming to a halt, do yourself and your wallet a favor by using the brakes and never downshifting past 2nd gear. So is downshifting bad? Yes, when you're doing it to the extreme.
Allowing plenty of space on the road ahead for a safe, assured stopping distance is also important. Engine braking is beneficial because it reduces brake system wear, improves fuel economy, and improves vehicle stability. However, engine braking is insufficient to keep the car under balance. So always keep in mind that downshifting or engine braking is meant to work in tandem with the brakes, not in place of them.
So when all is said and done, is downshifting bad for your vehicle? Downshifting has a variety of advantages when performed correctly. When a driver wants to slow down, it gives them the leverage they need. The procedure is often useful when attempting to alleviate the effects of jackknifing caused by the application of mechanical brakes. In addition, engine braking extends the life of brakes. You really just have to be wise when and how you are going to downshift.
