What is a Drive Cycle?
A drive cycle is a predetermined set of driving maneuvers that a car must pass in order to achieve its emissions goals. The drive cycle usually consists of a set of acceleration and deceleration steps, as well as some idling and coasting. The drive cycle is designed to simulate real-world driving conditions, and it must be passed in order for the car to meet the emissions standards set by the government.
Do All Cars Have to Pass the Drive Cycle?
Yes, all cars must pass the drive cycle in order to be certified as emissions compliant. This means that if a car does not pass the drive cycle, it cannot legally be driven on public roads.
Can a Car Pass the Drive Cycle Without Driving?
In most cases, a car cannot pass the drive cycle without being driven. This is because the drive cycle is designed to simulate real-world driving conditions, and it is not possible to accurately replicate those conditions without actually driving the car. However, there are some exceptions to this rule.
What Are the Exceptions to the Rule?
There are a few exceptions to the rule that a car must be driven in order to pass the drive cycle. One such exception is a hybrid or electric vehicle. These vehicles can often pass the drive cycle without being driven, as they are able to generate their own electricity.
Another exception is a vehicle that is equipped with an auxiliary power unit (APU). An APU is a device that is designed to simulate the engine of a car and is able to replicate the acceleration and deceleration of a real-world drive cycle. This allows the car to pass the drive cycle without being driven.
What Are the Benefits of Passing the Drive Cycle Without Driving?
One of the main benefits of passing the drive cycle without driving is that it can save time and money. As mentioned above, a hybrid or electric vehicle can often pass the drive cycle without being driven, and this can save time and money that would otherwise be spent on taking the car out for a test drive. Similarly, an APU can be used to simulate a drive cycle, which can save time and money that would be spent on actually driving the car.
Another benefit of passing the drive cycle without driving is that it can help to reduce emissions. As mentioned above, the drive cycle is designed to simulate real-world driving conditions, and this means that it can help to reduce emissions by ensuring that cars are running as efficiently as possible.
Are There Any Drawbacks to Passing the Drive Cycle Without Driving?
One of the main drawbacks of passing the drive cycle without driving is that it may not be as accurate as actually driving the car. This is because it is not possible to accurately replicate the real-world driving conditions without actually driving the car.
Another drawback is that it may not be possible to pass the drive cycle without the use of an APU. APUs can be expensive and may not be feasible for all vehicles.

Conclusion
Passing the drive cycle without driving is possible in some cases, but it is important to note that it may not be as accurate as actually driving the car. Hybrid and electric vehicles can often pass the drive cycle without being driven, as they are able to generate their own electricity. An APU can also be used to simulate a drive cycle, but this may not be feasible for all vehicles due to the cost. It is also important to note that there may be some drawbacks to passing the drive cycle without driving, such as the potential for inaccurate results and the need for an APU in some cases.
