Why do some cars have 6th gear?
Six gears either gives you a wider gear range, closer spacing between those gears, or some compromise between the two. But at the cost of added complexity and expense. For cars with larger engines, the sixth gear is useful as a high overdrive, keeping the engine speed down during higher-speed cruising.
Why do some cars have 4 gears?
All in all, there’s less engine load, and lower engine RPMs. The less an engine has to work, the less fuel it burns – simple as that. You’ll spend more money to buy a car with the extra gears because it’s better technology, more fuel efficient, and a popular choice.
Why do automatic cars only have 4 gears?
An additional gear was added to improve the acceleration of “performance cars”, or cars with small engines that needed an extra intermediate gear, which resulted if 4 speeds, and a fifth was added as overdrive to get better fuel economy at higher road speeds.
Is driving in 4th gear bad?
5 Answers. To answer your question, no it isn’t bad for your car to keep it in as high a gear as you can while still maintaining speed. As long as you are above idle in RPM and your engine isn’t lugging, you aren’t doing any damage.
Is it better to have 5 or 6 gears?
Efficiency. In recent 6-speeds, the extra speed from a 5-speed allows the engine to run at a lower RPM and save fuel, comparatively. This difference is most effective at highway driving speeds.
Why more gears in a transmission is better?
The extra gears provide better acceleration and with high gear often an overdrive ratio to slow engine speed, fuel economy was improved. Engines are smaller for better fuel economy and rev higher, but low rpm torque is usually lower, so having the additional gear ratios improves acceleration.
What’s better 4 speed or 5 speed?
More than just helping with accelerating, having more speeds helps with fuel economy. At any given speed, a transmission with more gears is better able to let the engine stay at a more efficient speed. So all things being equal, a five speed will be better at putting power out and more efficient while doing it.
Is a 4 speed manual transmission good?
You’re probably better off going with a 5 speed, and for around town driving and/or for lightning quick shifts, a good 4 speed might be your better choice.
Does more gears mean more speed?
A higher gear increases the speed of the wheel but decreases the torque (force) that the wheel produces (for a given engine speed). The faster the car goes, the faster the wheels need to spin but also the more force it needs to overcome air resistance.
Why do modern cars have so many gears?
Q: Why do new car automatic transmissions have so many gears (7+ speeds)? A: Primarily fuel efficiency. Automatics now achieve better fuel economy than manual transmissions. Transmissions adjust the speed of the wheels to the speed of the engine.
How Slow Can You Go in 4th gear?
What gear for which speed
| Gear | Speed |
|---|---|
| 2nd Gear | From 5mph to 15mph |
| 3rd Gear | From 15mph to 30mph |
| 4th Gear | From 30mph to 40mph |
| 5th Gear | 40mph upwards |
How fast do cars go in 4th gear?
What Speed Should You Change Gears?
| Gear | Speed |
|---|---|
| 1st gear | Between 0 mph and 10 mph |
| 2nd gear | Between 10 mph and 20 mph |
| 3rd gear | Between 20 mph and 30 mph |
| 4th gear | Between 30 mph and 40 mph |
Why do some cars have more gears than others?
One of the most popular reasons for making an automatic transmission with more gears is for smoother acceleration and deceleration. When there are more gears in the transmission, closer gear ratios can be used. For the driver, that means the engine RPMs don’t vary as much when speeding up and slowing.
What are timing gears and how do they work?
Timing gears are often employed in high-compression engines for their precise timing and strength, such as in diesel engines. Their unique sound can trick modern EFI systems, though, mimicking knock sensor vibrations. Timing belts’ shock-absorption properties dampen high-revving engine harmonics, as in NASCAR engines, for example.
How does a 4-speed transmission reduce fuel consumption?
A transmission with more gears typically reduces fuel consumption. No, it’s not magic. Take a common four-speed overdrive automatic transmission for example. Before it changes gears, it revs up to about 3,000 to 3,300 RPM on light acceleration, then starts the next gear at around 1,500 RPM.
Is a transmission with more gears more expensive to fix?
A transmission with more gears can cost more for your initial investment. You’ll spend more money to buy a car with the extra gears because it’s better technology, more fuel efficient, and a popular choice. Comparatively, it’s more expensive to fix.
