The world functions with the integrated work of different industries. One of the fastest-growing and essential industries today is the automotive industry. The automotive industry is such that it requires the movement of proper functioning of various aspects for its rise and growth. 

Therefore, companies must understand and implement all the necessary aspects and solutions to gain the best position in the competition. In the following decision, we will discuss the two most important and influential components of the automotive industry: the WLTP and the NEDC. We will also compare the two components and help you understand how Jato can assist your company ideally with its services and solutions for making the best use of these components and staying ahead in the industry. 

How do we define WLTP?

WLTP refers to the Worldwide Harmonised Light Vehicle Test Procedure. It is a laboratory test that helps and is functional in measuring the level of fuel consumption and the emissions of the harmful pollutant carbon dioxide from passenger vehicles. It also helps in measuring the pollutant emissions. 

With WLTP, the vehicles undergo a more excellent range of conditions. These driving conditions differ from the New European Driving Cycle or NEDC, which is outdated, and the WLTP is the test that replaces NEDC. The laboratory test makes it necessary for all the new-passenger vehicles to determine their official fuel consumption and emission data. 

How does WLTP work?

The test has a design that simulates the average car journey. Additionally, it requires using a chassis dynamometer on which it occurs and more commonly has the name of the “rolling road.” The test consists of the phases for acceleration, braking, and when the vehicle is stationary. The additional items that also come into account include air resistance, rolling resistance, optical requirements, and different engine and gearbox combinations. 

What benefits does WLTP provide?

WLTP offers various benefits, so it is popular and highly in use. Let us know more about its benefits, which are as follows. 

Ensures realistic driving behavior

The WLTP offers a measure of the efficiency of the vehicles. As a result, such measures offer the drivers a more precise and realistic understanding of the vehicle’s driving behavior. 

Helps save fuel

When drivers have the necessary knowledge and awareness about how much their vehicle consumes fuel, they can readily change their driving behavior to save fuel effectively. 

Helps in environmental safety 

The WLTP helps in understanding how much the vehicle is emitting pollutants. Therefore, such knowledge can make the driver aware of how much they must drive and use their vehicle to ensure that their use does not harm the environment. 

What does NEDC mean?

As we have already mentioned earlier, NEDC is the abbreviation for the New European Driving Cycle. It is a traditional and somewhat outdated test with a better and more influential replacement, the WLTP. The NEDC test includes the acceleration and the process of slowing down numerous times of the vehicles. It also involves testing the ability of the vehicle to drive at steady speeds and accompanying engine idling. 

Is WLTP better than NEDC?

The answer to whether WLTP is better than NEDC is yes. Firstly, NEDC is a traditional and outdated test. And its replacement, which is WLTP, is an excellent and more effective one, especially at present, which requires more emphasis on the sustainability of the environment. Additionally, WLTP generates more transparency while comparing various vehicles’ energy consumption and harmful carbon dioxide emissions. 

As a result, it makes the measurements free of the vehicle type and the manufacturers. They are also likely to be higher than the cycle of NEDC. The requirements and benefits of WLTP are far greater than that of NEDC. Therefore, the test of WLTP is more suitable for passenger vehicles than the NEDC test.
