WLTP Emissions Regulation introduction in 2019


The Worldwide Harmonised Light vehicle Test Procedure (WLTP) is a new method for testing a vehicles CO2 emissions and fuel consumption figures, which comes into force in September 2019 for Van models. This is applicable to all ‘light duty’ emission vehicles; covering both cars and vans up to a gross vehicle weight of 3.5t.
WLTP aims to provide test figures which more closely match the real life consumption that the customer will see on the road. Therefore, WLTP figures will be vehicle specific and values will change depending on individual vehicle specifications.
Tests will measure
- Fuel consumption
- C02 emissions
- Pollutant emissions
With the new WLTP certification process you can already begin saving fuel when configuring your vehicle. Because Mercedes-Benz Vans transparently issues the specific CO2 emission values for every single vehicle. That way you already know when you’re configuring a vehicle how the car’s equipment will affect the fuel consumption.
The mass of the vehicle can be reduced with weight-optimised component parts, such as the glass-fibre-reinforced plastic rear axle spring in the Sprinter, which reduces the vehicle weight by approx. 12 kg. You can optimise the wind resistance with a design of the wheels that is as closed as possible as well as with aerodynamically efficient attachments or underbody panelling. And the rolling resistance can be reduced, for instance, through appropriately optimised tyres. This means you can not only equip your vehicle to your wishes according to functionality and comfort, but also with the goal of a fuel consumption that is as low as possible.
