Last update: April 2022


The new procedure for consumption and emissions tests – WLTP (Worldwide Harmonized Light-Duty Vehicles Test Procedure) – ensures greater transparency and will gradually replace the NEDC (New European Driving Cycle). The WLTP is to become statutory for all EU member states - other countries are to consider its introduction in due course. 


Explanation regarding WLTP and NEDC

The WLTP was introduced on 1 September 2017. This new procedure for consumption and emissions tests is designed to deliver test results that more accurately reflect real driving behaviour than the previous NEDC. Since September 2017, all newly developed vehicles and vehicles with new powertrains have been certified under WLTP. From September 2018, the WLTP will then apply to all other newly registered vehicles. Accordingly, smart will switch to certifying its passenger car portfolio in accordance with WLTP by August 2018. In the transitional period, vehicles with WLTP and NEDC certification will be simultaneously available. In addition, there will be an NEDC consumption figure that is based on the WLTP and which will also be higher. This will be included in sales literature until 2020.

What does this mean for me as a customer?

Introduction of the WLTP (Worldwide Harmonized Light Vehicle Test Procedure) provides for greater transparency with regard to fuel consumption. Customers will benefit from the WLTP because it provides a more realistic yardstick for comparing the consumption and emissions figures of different vehicle models. However, the new test conditions will also mean changes in the CO2 and consumption figures: For process-related reasons, technically the same vehicle will have numerically higher CO2 and consumption figures under WLTP than under NEDC (New European Driving Cycle). This is due to more stringent conditions in the new cycle and the fact that optional equipment is taken into consideration, for example.

The WLTP delivers exact figures.

As the WLTP takes the vehicle's individual equipment into consideration, the figures are more exact than in the NEDC, and essentially constitute to vehicle-specific results. Everyday consumption will remain unchanged.
From September 2017, a new procedure for consumption and emissions tests is being introduced in the automotive industry; all newly certified vehicle models will be tested under WLTP. At the same time, the NEDC consumption figures will continue to be calculated and shown as the only valid consumption figures in promotional materials.
smart will be phasing in WLTP certification of its portfolio up to September 2018. From that date, it is likely that the new WLTP figures will be shown in all sales documents and other publications. NEDC consumption will be shown for discontinued models.

Introduction of the WLTP cycle.

The WLTP is intended to establish the worldwide harmonisation of test procedures. It is designed to deliver test results that more accurately reflect real driving behaviour than the NEDC procedure. Used vehicles will not be affected by this changeover and will keep their certified NEDC figures. Until at least the end of 2020, both WLTP and NEDC figures will be calculated for all vehicles. These figures will be included side by side in the vehicle documents with effect from the respective vehicle certification date. From 2021, the measured WLTP figures will be the only consumption and emissions figures for all passenger cars, providing each EU member state has adapted its tax system. The actual test phases of the WLTP are abbreviated to WLTC which, in turn, is divided into three classes. Almost every passenger car will be tested under WLTC Class 3 (Worldwide Harmonized Light-Duty Vehicles Test Cycle), which covers all passenger cars with a power/weight ratio of more than 34 kW/t (46 hp/t kerb weight).

WLTP: greater transparency.

The WLTP provides smart customers with vehicle-specific consumption figures which are more realistic and more transparent. While cross-manufacturer and cross-model comparability is retained, the measured consumption figures are a more accurate reflection of everyday driving and take more factors into consideration than the NEDC. smart is an advocate of both new, more realistic laboratory testing and on-road measurements. This ensures greater clarity, transparency and certainty for smart customers. The introduction of WLTP and RDE (Real Driving Emissions) marks an important step in this direction.

What does this mean for customers?

In future, customers will be able to establish the CO2 figure for their vehicle model more accurately than has been possible to date, by selecting the relevant optional equipment. To ensure clarity and maximum possible transparency, smart will actively follow the introduction phases of the WLTP and provide dealers and customers with targeted information. This will also include a new form of information based on equipment specification: from the model with the lowest energy consumption to the version with the highest energy consumption. In numerical terms, this spread ranges from "WLTP Low" (minimum scope of optional equipment) to "WLTP High" (maximum scope of optional equipment).

How to obtain your RDE results.

Find out about your vehicle's emissions under real-life conditions.

The term "Real Driving Emissions" (RDE) denotes the real-life exhaust emissions of cars, trucks and buses in everyday use. To date, exhaust emissions measurements for type approval have taken place exclusively on dynamometers. When the RDE (EU) 427/2016 legislation came into force in March 2016, it also became necessary to measure emissions under real-life driving conditions within defined parameters. Together with the RDE limits for the real-life operation of vehicles which have been mandatory since September 2017, this represents an important step towards a cleaner, low-emission future for the automobile.

The RDE results for our smart vehicles, which have been obtained both by us as the manufacturer and by independent, certified technical services, can be requested here, specifying your smart vehicle's PEMS test family (

Frequently asked questions.


What is WLTP?

The abbreviation WLTP stands for Worldwide Harmonized Light-Duty Vehicle Test Procedure. This is a test procedure which assesses a vehicle's consumption and emission levels on a roller dynamometer. Phase-in of the WLTP has been underway since 1 September 2017. It is replacing the previous NEDC test procedure.

The dynamic character of the WLTP means that it comes markedly closer to real-life driving than was previously the case. The WLTP is characterised by significantly higher acceleration events and by a considerably more dynamic driving profile. The maximum speed is raised to 131 km/h and the average speed rises to 47 km/h.

The driving time is extended by 10 minutes, the share of motorway trips simulated on the roller dynamometer is higher and stationary time is shortened. The distance covered is doubled to 23 kilometres.

The shift points are calculated in advance and are specific to the vehicle and its powertrain. All optional equipment with an influence on vehicle aerodynamics, rolling resistance and vehicle mass will in future be factored into the measurement. The power consumption of comfort/convenience functions will likewise lead to a higher CO2 figure. The only exception in the first stage of the WLTP is the air conditioning. With the WLTP, the goal is to introduce a globally binding standard.

The EU countries are leading the way here. This will help to compare the fuel consumption and pollutant emissions of vehicles from different manufacturers. The standards will additionally help authorities to verify compliance with the statutory emission limits – from hydrocarbons (HC) through carbon monoxide (CO) and nitrogen oxides to particulate matte.

What is WLTC?

The WLTP driving cycles are referred to as WLTCs – Worldwide Harmonized Light-Duty Vehicles Test Cycles. For different vehicle classes, the WLTP has three different driving cycles that take the particular power/weight ratio into consideration. The majority of passenger cars registered in the EU will be assigned to WLTC Class 3, which covers a power/weight ratio of more kW/t (34 46 hp/t). The test cycle for Class 3 vehicles consists of four parts – Low, Medium, High, Extra High. These simulate driving in an urban and extra-urban environment, on expressways and on motorways.

What is NEDC?

The NEDC (New European Driving Cycle) is the currently valid test cycle for passenger cars. The first European driving cycle came into effect in 1970 with the goal of providing customers with comparable and reproducible figures across all manufacturers. In 1992, the NEDC was extended beyond urban traffic. At 34 km/h, the average speed in the NEDC is low, as are the acceleration events and maximum speed of 120 km/h. The composition of the cycle no longer corresponds to the current average breakdown of different types of roads covered on journeys.p>

The measurements do not give any consideration to aerodynamics and weight aspects or the energy consumption of additional equipment and comfort features such as air conditioning, radio or seat heaters. There are also technological parameters which tend to cause discrepancies.

The start/stop technology has a relatively large influence in the NEDC, for example, because the NEDC includes a high share of stationary time. the case of vehicles with manual transmission, vehicle-specific parameters are not taken into consideration when the shift points are calculated.

This can lead to major deviations from real-life consumption levels. In the face of ongoing technical progress, the NEDC is now outdated.

What is RDE?

RDE stands for Real Driving Emissions and is a road test for assessing pollutant emissions. It describes a vehicle's emissions under real on-road conditions. To date, exhaust emissions measurements for type approval have taken place exclusively on dynamometers. With effect from March 2016, emissions must also be measured within a defined framework under real driving conditions. APEMS (Portable Emissions Measurement System) is used to measure nitrogen oxide (NOx) and carbon monoxide (CO) emissions. Particulate emissions are also to be assessed in due course. There is no set cycle; driving and measuring take place in real everyday traffic in compliance with road traffic regulations. The vehicles are driven on public roads for between 90 and 120 minutes, spending one third of this time on urban roads, extra-urban roads and motorways respectively. An average speed of between 15 and 30 km/h is specified for city driving, while the speed on motorways is to be at 90 and at least 110 but no higher 145 km/h. The outside temperature must be between 0 and 30 °C, the air conditioning is to be on.

The test drive must not take place at over 700 metres above sea level and must not involve a difference in altitude of more than 100 metres. Since September 2017, compliance with the Euro 6 emissions limits has been compulsory in the RDE road tests. This has initially applied since 1 September 2017 to newly certified models and will apply to all models as of 1 September 2019 at the latest.
