MAN TGE becomes even more climate-friendly
From 1 January 2022, vans of class N1, i.e. up to 3.5 tonnes permissible total weight, must be equipped with engines of the Euro 6d emission level. MAN Truck & Bus already meets this standard with its TGE vans – and thanks to the new engine control unit and revised AdBlue® injection, it saves around ten percent CO2 with every kilometer.
The entire transport sector is currently undergoing a transformation process. Very soon, electric drives in commercial vehicles will be as normal as the high-performance computer in your pocket already is. But on the way there, the combustion engine is still urgently needed. And it is being further developed. The MAN diesel engines now in use will be even cleaner and more economical. Both benefit the environment directly with every new vehicle put into service.
But first things first: from 1 January 2022, all newly registered N1 transporters in the EU must comply with the Euro 6d emission standard. However, the difference between the previously applicable Euro 6d temp and Euro 6d standard does not lie in the emission limit values themselves, but the permissible exceedance factor of the limit values in real road traffic (RDE = Real Driving Emission) changes. This indicates by how much the legal limit value for nitrogen oxides (NOx) may be exceeded between test bench test according to WLTP driving cycle and real driving operation. The overrun factor was reduced from 2.1 to 1.43 with Euro 6d.
The new MAN engines for the TGE up to 3.5 tons also score with a considerable reduction in fuel consumption and thus also in CO2 emissions. The reduction for all engines is between 9 and 10 percent. In concrete figures for an L3H3 panel van (normal wheelbase, high roof) with an output of 103 kW (140 hp), this means that previously the CO2 emissions according to the WLTP measuring cycle were 253 g/km (9.7 l/100 km), from now on only 230 g CO2/km (8.8 l/100 km) are necessary. With the standard introduction of rolling resistance-optimized A-label tyres from the end of November this year, consumption will be reduced by a further 3 g CO2/km (8.7 l/100 km).
The Euro 6d engines have a newly developed exhaust gas cleaning near the engine, a new engine control system, an enlarged AdBlue® container with a capacity of 30 liters and a new exhaust system. The Euro 6d engines for the MAN TGE are now installed as standard.
A new technology that comes into the vehicle with the Euro 6d engine is the SCR system called "Twin Dosing". It is mainly responsible for the CO2 savings mentioned above. These result from the additional second SCR catalyst and a double SCR injection. (SCR = Selective Catalytic Reduction.) In twin-dosing technology, the reducing agent AdBlue® is injected into two reduction catalysts arranged one behind the other. One of them close to the engine in the exhaust gas cleaning module, the second away from the engine on the underbody of the vehicle. This concept ensures an effective reduction of nitrogen oxides at high and low exhaust gas temperatures.
In addition to the now even more economical 2.0-litre diesel engine, the MAN TGE is also available as an all-electric MAN eTGE and is convincing more and more customers in Europe with its locally emission-free drive.
The vehicles and products displayed on this website may differ in terms of shape, design, colour and scope of supply. Some of the images may include special equipment, accessories and decorative elements which are subject to an additional charge. The technical features and equipment of the vehicles described are merely examples and may differ, in particular on a country-specific basis. We reserve the right to make changes at any time.
Our vehicles are equipped with summer tyres as standard. Please check possible national regulations about whether winter tyres are required. Your MAN partner will be happy to advise you.
The specified fuel consumption and emission data has been determined according to the measurement procedures prescribed by law. Since 1st September 2017, certain new vehicles are already being type-approved according to the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), a more realistic test procedure for measuring fuel consumption and CO2 emissions. It is currently still required by law to state the NEDC figures for vehicles for passenger transport with registration class M1. In the case of new vehicles which have been type-approved according to the WLTP, the NEDC figures are derived from the WLTP data. In cases where the NEDC figures are specified as value ranges, these do not refer to a particular individual vehicle and do not constitute part of the sales offering.
Additional equipment and accessories (e.g. add-on parts, different tyre formats, etc.) may change the relevant vehicle parameters, such as weight, rolling resistance and aerodynamics, and, in conjunction with weather and traffic conditions and individual driving style, may affect fuel consumption, electrical power consumption, CO2 emissions and the performance figures for the vehicle.
Efficiency classes rate vehicles for passenger transport with an M1 passenger vehicle registration, according to the CO2 emissions under consideration of the empty vehicle weight. Vehicles which conform to the average are classified as D. Vehicles which are above the current average are classified as A+, A, B or C. Vehicles which are below average are classified as E, F or G.
Additional information regarding the official fuel consumption, and the official specific CO2 emissions of new vehicles for passenger transport, with an M1 passenger vehicle registration, can be found in the “Guide on the fuel economy, CO2-Emissions, and power consumptions of all New Passenger Car Models”. This guideline is available free of charge at all sales points and from the DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. 1, 73760 Ostfildern-Scharnhausen, Germany.

In vehicle classes N1, N2 and M2, coolant of the type R134a is used. MAN TGEs of vehicle class M1 require coolant of the type R1234yf. The GWP value of the coolant used is 1.430 (coolant type R134a) and 4 (coolant type R1234yf). The fill levels depend on the coolant compressor and varies between 560 - 590 grams.
