Do Police Car Transmissions Keep Engine in Higher Revs?

Introduction

Police cars are often seen driving at high speeds and making sudden stops. To do this, they need to have engines that are powerful and responsive. One way to achieve this is to keep the engine in higher revs.

How Police Car Transmissions Work

Police car transmissions are typically designed to keep the engine in higher revs than normal passenger cars. This is done by using a shorter final drive ratio. A final drive ratio is the number of times the driveshaft turns for every one revolution of the engine. A shorter final drive ratio means that the engine will turn more times for every turn of the wheels.

For example, a typical passenger car might have a final drive ratio of 3.50:1. This means that the driveshaft will turn 3.5 times for every one revolution of the engine. A police car, on the other hand, might have a final drive ratio of 4.10:1. This means that the driveshaft will turn 4.1 times for every one revolution of the engine.

The shorter final drive ratio in police cars allows the engine to stay in higher revs at lower speeds. This gives the car more power and responsiveness when it needs to accelerate quickly.

Benefits of Keeping the Engine in Higher Revs

There are several benefits to keeping the engine in higher revs, including:

• Increased power: Higher revs allow the engine to produce more power. This is because the engine is able to burn more fuel and air at higher speeds.
• Improved responsiveness: Higher revs also make the engine more responsive. This means that the car will accelerate more quickly when you press the gas pedal.
• Better fuel economy: Surprisingly, keeping the engine in higher revs can actually improve fuel economy. This is because the engine is able to operate more efficiently at higher speeds.

Drawbacks of Keeping the Engine in Higher Revs

While there are several benefits to keeping the engine in higher revs, there are also some drawbacks, including:

• Increased wear and tear: Keeping the engine in higher revs can lead to increased wear and tear on the engine components. This is because the engine is operating at higher speeds and temperatures.
• Reduced engine life: Keeping the engine in higher revs can also reduce the engine’s life. This is because the engine is more likely to overheat and suffer from other problems when it is operated at high speeds.
• Increased noise: Keeping the engine in higher revs can also make the car louder. This is because the engine is producing more noise at higher speeds.

Conclusion

Whether or not to keep the engine in higher revs is a decision that should be made on a case-by-case basis. There are several benefits to keeping the engine in higher revs, but there are also some drawbacks. Ultimately, the best decision for you will depend on your individual driving needs.
