Inner-city traffic is all about short distances: From the workshop to the construction site and back. Delivery runs all over the city. Transporters travelling in inner cities usually only cover short distances. The eTGE is the ideal vehicle for this task. Numerous studies have shown a daily average mileage of 60 - 80 km, which the MAN eTGE handles effortlessly.

According to WLTP, the MAN eTGE achieves a range of 110 to 115 km. This value is based on a driving cycle with predominantly high speeds. Depending on other factors, such as route topography or the use of auxiliary consumers, the range can be increased even further. However, there are certain basics that apply to the MAN eTGE as much as for any other electric vehicle: You should always plan for a reserve, since individual driving styles can significantly influence the range.

RANGE CRITERIA

Heating and air conditioning

An electric drive produces significantly less waste heat compared with a combustion engine. For this reason, the MAN eTGE uses a highly efficient, purely electric heating and air conditioning system. The heater’s power consumption may still considerably reduce the range of your electric vehicle, especially at lower minus temperatures. We can show you how to use the right strategy to reliably manage your daily routes, e.g. using targeted pre-tempering of your electric van while it is being charged.

Auxiliary consumers

Vehicle lighting, multimedia systems, USB ports and assistance systems also require battery power. In the MAN eTGE, all auxiliary consumers are therefore designed for maximum energy efficiency. This means they only have a noticeable influence on the scope if they continue working to their full extent during prolonged stops. The eTGE offers you a savings mode that reduces the auxiliary consumer’s energy use.

Traffic and driving cycles

Electric vans can play to their strengths in urban environments in particular: the current average speeds in typical city traffic measure between 14–18 km/h, while the speed limits on most routes are at 50 —60 km/h. Electric drive concepts are highly energy efficient in these speed ranges. In addition, unlike driving with a combustion engine, stop-and-go traffic no longer creates a burden on your energy balance. Quite the opposite: Using recuperation, the MAN eTGE delivers electrical energy back to the battery when coasting.

Driving style

Forward-thinking driving saves energy, and the same applies to every vehicle. With the electric drive, however, a well-trained driver can also achieve a considerable increase in range. Gentle acceleration and targeted use of recuperation significantly reduce energy consumption.

Topography and charging

The weight of the payload and route’s terrain profile have relatively limited impact on the range of your electric van. Heating operation and high speeds have considerably more influence. Nevertheless, it is important to carry out a detailed analysis of your route network and charging requirements, as this can provide you with helpful information on optimising driving routes and vehicle circuits.

NEW TEST CYCLE

The acronym WLTP stands for “Worldwide Light Duty Vehicle Test Procedure”. The new standard for test bench measurements is intended to be valid worldwide. The test conditions for the WLTP are designed in such a way that they reflect real driving conditions as accurately as possible. At the same time, the measurements performed under controlled conditions in the laboratory ensure that it is possible to compare the WLTP data of the vehicles beyond national borders.

What are the advantages of introducing the WLTP?

The WLTP data makes it possible for you to better estimate the consumption, environmental sustainability and range of a vehicle. To ensure this, extensive comparative data was collected during the development of the new WLTP test cycle: Test engineers have been testing thousands of passenger vehicles and light commercial vehicles across various countries, on the test bench as well as under real driving conditions. Based on these comparative measurements, a team of experts was able to define improved test parameters. These parameters ensure that the results of the WLTP test bench measurements are closer to the actual usage and emission values under real driving conditions. The previous NEFZ standard was not able to guarantee this.

How close to reality is the WLTP driving cycle?

The WLTP values for fuel consumption, CO₂ emissions and range are fairly close to the usage and emission values of a vehicle under real driving conditions on the road.

What are the differences between the vehicle tests according to the WLTP and NEFZ?

The WLTP test cycle includes more dynamic driving processes than a test bench measurement according to NEFZ. For example, each vehicle has to pass through numerous different acceleration and braking phases. The most important differences between the two standards lie in the length of each cycle, the type of driving phases and the distances covered during the test drives. Furthermore, the WLTP standard uses objective specifications for average and top speeds as well as the test temperatures. In addition, the WLTP measurements take into account the influence of optionally available equipment variants of the vehicles.
However, even the WLTP cannot include all factors that might influence these values under real driving conditions. The actual usage and emission values vastly depend on the individual driving style and environmental factors such as weather conditions, route profile and the vehicle load for each specific application.

How do the nominal values differ according to the WLTP and NEFZ?

In most cases, the WLTP test results in higher CO₂ values in g/km than the previous nominal value of the NEFZ, measured on identical vehicles. Firstly, this is due to the more realistic dynamics of the driving profile of the WLTP test cycle. Secondly, the new standard takes the individual vehicle equipment of the customer into account. This is a first time and was not included in the NEFZ test cycle.

What is the difference between WLTP and RDE?

The acronym RDE stands for “Real Driving Emissions”. During the RDE test, test engineers measure the exhaust gas emissions of nitrogen oxides (NOX) and particles (particulate matter) under real driving conditions on the road. For this purpose, a mobile emissions measurement system (PEMS) is used. As opposed to this, the vehicles absolve the WLTP test cycle under standardised test conditions on a chassis dynamometer. Both methods are important for measuring, evaluating and further reducing the environmental impact of vehicles. Since September 2019, vehicle tests according to the WLTP and RDE methods are mandatory for all vehicle manufacturers within the EU.

Which countries will be implementing the WLTP standard?

Within the 28 member states of the EU, the WLTP standard has already been valid for all new passenger vehicles since September 2017. For light commercial vehicles, the new standard will be replacing the previous NEFZ measurements from September 2019. From 2021, the CO₂ target values for vehicle fleets will also be calculated based on the WLTP test bench measurements.
Based on current information, the following non-EU countries will be implementing standardised vehicle tests according to the WLTP: Switzerland, Liechtenstein, Norway, Iceland, Israel and Turkey.
