A final drive is the gear ratio between the engine and the wheels of a vehicle. The 4.7 final drive means that for every 4.7 revolutions of the engine, the wheels will make one revolution.
A 5.1 final drive means that for every 5.1 revolutions of the engine, the wheels will make one revolution.
This means that the 5.1 final drive will have a higher gear ratio, making the vehicle more efficient at higher speeds, but possibly less efficient at lower speeds.
The difference in acceleration between the two final drives may not be significant, but the 5.1 final drive may result in slightly slower acceleration due to its higher gear ratio.
It is important to note that the final drive ratio can affect the overall performance of the vehicle and it is best to choose a final drive that is appropriate for the intended use of the vehicle.
What Is Final Drive Ratio – 4.7 and 5.1 Final Drive
The final drive ratio, or gear ratio, refers to the relationship between the engine and the wheels of a vehicle. It is represented as a numerical value, such as 4.7 or 5.1.
A 4.7 final drive means that for every 4.7 revolutions of the engine, the wheels will make one revolution. This results in a lower gear ratio, which means that more torque is transmitted to the wheels, and the vehicle may have quicker acceleration at lower speeds.
However, a lower final drive ratio may also result in less efficient highway driving due to the higher engine revolutions per mile.
A 5.1 final drive means that for every 5.1 revolutions of the engine, the wheels will make one revolution. This results in a higher gear ratio, which means that less torque is transmitted to the wheels, and the vehicle may have slower acceleration at lower speeds.
However, a higher final drive ratio may result in more efficient highway driving due to the lower engine revolutions per mile.
It is important to note that the final drive ratio can affect the overall performance of a vehicle, and it is best to choose a final drive that is appropriate for the intended use of the vehicle.
The Effect of Final Drive on Acceleration
The final drive ratio, or gear ratio, refers to the relationship between the engine and the wheels of a vehicle.
It determines how much torque is transmitted to the wheels and can have an impact on the acceleration of the vehicle.
A lower final drive ratio, such as a 4.7, will result in more torque being transmitted to the wheels, potentially leading to quicker acceleration. A higher final drive ratio, such as a 5.1, will result in less torque being transmitted to the wheels, potentially leading to slower acceleration.
However, the difference in acceleration between a 4.7 final drive and a 5.1 final drive may not be significant.
The final drive ratio is just one factor that affects acceleration, and there are many other variables at play, such as the power and weight of the vehicle, the tire grip, and the transmission ratio.
Additionally, the intended use of the vehicle should be considered when choosing a final drive ratio. A higher final drive ratio may be more suitable for highway driving, while a lower final drive ratio may be more suitable for city driving or off-road use.
In summary, the final drive ratio can have an effect on the acceleration of a vehicle, but it is just one factor among many, and the difference between a 4.7 final drive and a 5.1 final drive may not be significant.
4.7 Final Drive vs 5.1 Final Drive
| Facts | 4.7 Final Drive | 5.1 Final Drive |
| Gear Ratio | 4.7:1 | 5.1:1 |
| Acceleration | Quicker at lower speeds | Slower at lower speeds |
| Suitable for | City driving, off-road use | Highway driving |
| Engine RPM | Lower at a given speed | Lower at a given speed |
| Fuel efficiency | Lower at higher speeds | Higher at higher speeds |
| Gear shifting | More frequent at higher speeds | Less frequent at higher speeds |
Final Words
The final drive ratio, or gear ratio, refers to the relationship between the engine and the wheels of a vehicle.
It is an important factor that can affect the overall performance of a vehicle. A lower final drive ratio, such as a 4.7, will result in quicker acceleration at lower speeds and may be more suitable for city driving or off-road use.
However, a lower final drive ratio may also result in less efficient highway driving and may require more frequent gear shifts to maintain optimal engine RPM.
On the other hand, a higher final drive ratio, such as a 5.1, will result in slower acceleration at lower speeds but may be more suitable for highway driving and may result in fewer gear shifts required to maintain optimal engine RPM.
Ultimately, the choice between a 4.7 final drive and a 5.1 final drive will depend on the intended use of the vehicle and the desired performance characteristics.
