WLTP Driving Fuel Consumption
Leading the way: Opel now shows fuel consumption data determined by the WLTP driving cycle which makes it easier for customers to estimate their vehicle's daily fuel consumption. Compared to the current NEDC (New European Driving Cycle), the WLTP (Worldwide Harmonised Light Vehicles Test Procedure) driving cycle is closer to today's, real-world driving conditions.

More Transparency: Closer to Daily Consumption.

As early as 2015, Opel announced that it would test future models according to the WLTP (Worldwide Harmonized Light-Duty Vehicles Test Procedure) driving cycle 1 . From autumn 2018, the publishing of the WLTP driving cycle values will be made legally binding. Unlike the current compulsory NEDC (New European Driving Cycle), the WLTP cycle relates closer to modern driving conditions. Therefore we are already making it easier for customers to estimate the daily fuel consumption of their vehicle.

* In accordance with Regulations (EC) No 715/2007 and (EC) No 692/2008 (applicable version). The figures do not refer to a specific vehicle and are not part of a specific offer but serve purely for comparing different vehicles.

 

** The lower figure represents the fuel consumption of a vehicle with the most economical equipment for that engine and transmission combination. The upper value represents the highest fuel consumption measurement for corresponding vehicle fitted with equipment that makes it less fuel efficient. The figures obtained provide a good overview and a useful indication of the expected fuel consumption.  

 

The fuel consumption of a vehicle depends on where and how the vehicle is driven: city traffic, country roads or motorways. The new WLTP driving cycle takes into account conditions that are closer to everyday driving compared to the current NEDC standard. It allows you to see more realistic fuel consumption figures. The current NEDC determines 'urban / extra-urban / combined' values (as stipulated by  Regulations (EC) No. 715/2007 and 692/2008) based on a theoretical driving profile, in contrast the new WLTP uses 'real' driving profiles drawn from a global statistical survey. The WLTP driving cycle is divided into four parts with different average speeds: low / medium / high / extra high. Each part contains a variety of driving phases, stops, acceleration and braking phases that represent everyday driving profiles. Each engine/transmission combination is tested with the most economical as well as the most uneconomic vehicle equipment.

 

The figures released for the Opel Astra from June 2016 shows a a lower and higher fuel comsumption range for each of the four WLTP phases. The lower figure represents the fuel consumption of a vehicle with the most economical vehicle equipment for that engine and transmission combination. The upper value represents the highest fuel consumption measurement for corresponding vehicle equipped with equipment that renders it less efficient. The figures obtained provide a good overview and a useful indication of the expected fuel consumption. 

 

Please note: The WLTP fuel figures are determined using a standardised, predefined drive cycle on a test rig.

How You Benefit

More Realistic Consumption Figures.

Current fuel consumption figures were originally introduced in 1992 as part of the 'New European Driving Cycle' (NEDC). These NEDC figures were initially designed to offer comparative figures between vehicles. However it is widely accepted that these figures do not reflect real-world driving conditions. As a result the 'Worldwide Harmonised Light-Duty Vehicle Test Procedure' (WLTP) has been developed to give more realistic on-the-road fuel data.

 

The new test proceedure takes into account: 

  • More realistic driving dynamics and outside temperatures 
  • Greater test distances  
  • Higher average and maximum speeds 
  • Shorter stops 
  • More braking and acceleration
  • Optional equipment and its effect on fuel consumption.

 

The publishing of WLTP driving cycle values will be a legal requirement for all automotive manufacturers from Autumn 2018.

What Is The WLTP Driving Cycle?

WLTP Driving Cycle

The current NEDC determines 'urban / extra-urban / combined' fuel consumption figures based on a theoretical driving profile. In contrast the WLTP uses 'real' driving profiles drawn from a global statistical survey. The WLTP driving cyle is divided into four parts with different average speeds: low, medium, high and extra high. Each part contains a variety of driving phases, stops, acceleration and braking phases that represent everyday driving profiles. Each engine/transmission combination is tested with the most economical as well as the most uneconomical vehicle equipment.

 

Opel is currently in the process of testing each and every model. The published figures define a range from the lowest to the highest consumption for each engine/transmission combination. This gives a much better indication of the expected consumption for each model. 

 

Please note: The WLTP fuel figures are determined using a standardised, predefined drive cycle on a test rig.

Questions About New Fuel Consumption Figures

Why is the NEDC out of date?

The NEDC (New European Driving Cycle) was introduced in 1992, however cars, roads and driving behaviour have changed since then. The NEDC is an artificial laboratory test and serves solely to compare different vehicles, not to reflect normal consumption. This means that real consumption is often very different from the NEDC information. The main reasons include:

 

  • The theoretical driving profile does not match real user profiles.
  • Insufficient acceleration.
  • Too many stop phases.
  • Does not incorporate higher speeds, eg. motorways. This gives an average speed that is too low.
  • Gear shifting points are broadly defined by transmission type, eg. they are the same for all cars with manual transmission.
  • Optional equipment is not considered.

What does the NEDC measure?

The NEDC has been legally binding for all vehicles since 1992. The NEDC is based on a somewhat theoretical driving profile and consists of two parts: In the first 13 minutes, it simulates a drive in city traffic with many stop-and-go phases. The second part corresponds to an extra-urban journey at a maximum speed of 120km/h.

What are the four parts of the WLTP?

In order to determine more realistic consumption data, the WLTP driving cycle is based on a global statistical survey of real driving profiles. This includes four parts with different average speeds which are generally representative for operating profiles around the world: low, medium, high and extra high. Each phase includes different amounts and degrees of acceleration, braking, stopping, etc. that reflect everyday driving situations.

What is the difference between NEDC and WLTP?

Since the introduction of NEDC in 1992 cars and driving styles have changed significantly. The WLTP test parameters have been redefined to reflect real conditions more closely. They now include:

 

  • Longer cycle times (30min vs 20min)
  • Shorter stopping times (13% vs 25%)
  • Longer distances (about 23km vs 11km)
  • Higher speeds (max.130km/h vs 120km/h)
  • Almost 50% higher average speeds
  • Higher maximum acceleration and more acceleration phases
  • Approximtely 20-30% higher power usage - based on more dynamic driving styless
  • More realistic representation of aerodynamics and tyre resistance
  • Consideration of optional equipment in the vehicle

 

Values obtained with WLTP are comparable worldwide, while the NEDC values are only valid for Europe.
