WLTP Fuel Saving


Reflecting real-world driving conditions

Here’s what you need to know about the new emission and fuel economy tests that will be carried out on new cars in Europe.

Why greater accuracy is better for everyone

The New European Drive Cycle (NEDC) has been replaced by the Worldwide Harmonized Light Vehicles Test Procedure (WLTP). This new set of tests puts new cars through a greater range of driving situations (urban, suburban, main road, motorway) improving the consumers’ ability to relate to the real-life performance of their cars.

The key differences

While the WLTP driving cycle will still test cars in a laboratory setting, it will take into account situations that you experience in everyday life. The new method will allow you to estimate your daily fuel consumption much more accurately than using the old NEDC standard. Another benefit of WLTP is that consumers will see figures that capture very different driving styles and thereby help them to understand the effect of their own driving style on fuel consumption and emissions.

A lot has changed in road infrastructure, car technology and traffic conditions since NEDC was first introduced in Europe. The new testing procedures are based on the results of a global survey and have been defined to create more of a real-life driving profile.

Even though WLTP will be more accurate, it will not cover all the variations globally – and certainly not each individual driving style. The new tests take into account diverse acceleration and braking situations – mirroring the way most of us drive today.

Weather, traffic congestion and passenger numbers will continue to play a major role in your fuel economy. This is why recreating all the variables in a laboratory environment remains a challenge, and can never exactly simulate your individual driving style.

To help you better understand what the changes consist of and how they might affect you – we’ve put together a few key questions and answers.

  • Who set the tests?

    The European Union is responsible for the implementation of the WLTP. The figures obtained after testing each vehicle will become part of the EU’s certificate of conformity – a requirement before any new vehicle can be sold across Europe.

  • Who will it affect?

    For now, this change will apply to all new cars sold in the EU and all countries that follow EU regulations, such as EEA countries.

  • What does it mean?

    WLTP stands for ‘Worldwide Harmonised Light Vehicle Test Procedure’, NEDC stands for ‘New European Driving Cycle’.

  • Why is it important?

    All conditions for testing, measuring and gathering the results are defined by EU law. This allows for standardized and repeatable procedures to facilitate a fair comparison between car models.

  • Why is it better?

    WLTP is more accurate, due to the fact that more variables will be taken into account. These include: more realistic acceleration and deceleration, stricter vehicle preparations before the test, the inclusion of higher speeds in the testing process, and greater consideration of optional equipment and technology.

  • What isn't tested?

    The tests still struggle to account for real world variables such as: different driving behaviours of individuals, the maintenance condition of the vehicle, the vehicle load, various traffic conditions, and the impact of weather conditions.

  • When was WLTP introduced?

    WLTP certification came into effect for new types of cars in September 2017. Since September 2018 all new cars must be certified according to WLTP.

Reduce emissions, save money

We’ve compiled a list of tips that will help you get more fuel efficiency from your car.

Fuel saving tips

Engine performance, efficiency and innovation

We believe that lower fuel consumption and exceptional performance are not mutually exclusive. This is the mind-set that allows us to continually develop engine innovations across our range of premium sedans, crossovers, SUVs and estates – with the clear ambition that the impact of our cars is minimal for the environment.

Downsizing without compromise
Downsizing without compromise

The number of cylinders no longer determines power or drivability. At Volvo Cars we have optimised the size and weight of our engines without compromising on power or performance.

Lightweight and efficient
Lightweight and efficient

Everything in the engine is tuned to reduce loss of energy and make the most of the fuel. Surfaces are treated to reduce friction, while sensors ensure that the pressure and temperature of every injector is optimal.

Going electric
Going electric

Our Drive-E engines were created with electrification in mind. The compact size of the 4-cylinder engines means that the electric motor can be fitted in the front or rear of the vehicle. The battery pack is located in the centre of the vehicle, contributing to greater stability and safety.

Our approach to sustainability

We are determined to reduce the impact of our vehicles on the environment by introducing more efficient engines, lightweight designs, and a wider range of hybrid and electric cars.
