How can we drive more value in transport?

The success of the commercial vehicle has consequences for the climate

The pressure on the industry is growing: fleets must be comprehensively renewed and vehicle manufacturers must increasingly use particularly sustainable transport solutions. With Regulation (EU) 2019/1242, CO₂ fleet target values were introduced for the first time for commercial vehicles in vehicle classes N2 and N3:

  • CO₂ emissions per km must be at least 15% lower from 2025 than in the base year 2019/2020.
  • Revision of the CO₂ fleet targets in the coming year, tightening of the target values is considered likely.
  • Assessment basis is the Vehicle Energy Consumption Calculation Tool (VECTO)

Innovative trailer technologies from the BPW Group are already contributing to greater sustainability - and doing so particularly economically:

  • Lift axle
  • Self-steering axle
  • ARC
  • Telematics
  • Airlight II
  • Tyre pressure systems

LIFT UP YOUR TRAILER! Lifting the first axle at partial load increases the load on the tyres on the second and third axles. There, the temperature rises and the rolling resistance decreases, so that 0.4 percent fuel can be saved in long-distance transport. The lower the ambient temperature, the greater the reduction in rolling resistance. This is true at least when driving straight ahead.

A lift axle also offers advantages when cornering. Rigid axles are reluctant to steer, so they resist a change of course and thus generate a power loss, the so-called cornering resistance. If one of the three axles is lifted when cornering, the unwillingness to steer is reduced and the energy losses are lower.

  • Lift axles will be included in the VECTO calculation from 2024.

SAFER THROUGH THE CURVES! The self-steering axle LL shows its strengths especially in narrow traffic areas in delivery and distribution traffic. Thanks to better manoeuvrability in curves as well as when manoeuvring and turning, you benefit from easier vehicle handling, protect the tyres and consume less fuel. 

With an average consumption of 30 litres per 100 kilometres, realistic fuel savings of 0.9 to 1.5 litres per 100 kilometres result in practice. Given an annual mileage of 120,000 kilometres, this means that a fleet of ten articulated trucks can save 10,800 to 18,000 litres. This in turn corresponds to a CO₂ reduction of 28.6 to 47.7 tonnes.

  • The self-steering axle will be included in the VECTO calculation from 2024.

THE MANOEUVRING MIRACLE! With ARC, you benefit from all the advantages of the self-steering axle - even when reversing and manoeuvring. With Active Reverse Control, BPW has developed a new electrohydraulic auxiliary steering system that controls the steering axle fully automatically when reversing at a speed of up to 10 km/h. This increases the agility and manoeuvrability of your vehicles when reversing. This increases the agility and manoeuvrability of your vehicles when reversing and reduces time and tyre wear. For an annual mileage of 100,000 kilometres, this can save around 1,000 litres of diesel and four tyres - thanks to the improved cornering behaviour.

  • From 2024, self-steering axle will be included in the VECTO calculation! With Active Reverse Control, you can make even more savings.

Creates transparency! Systems like those from idem telematics result in fuel savings of up to ten percent. These systems realise these savings by networking the load, vehicle and driver into an "Internet of Transport" and thus contribute to increasing the utilisation rate of the load space and at the same time reducing the transport distance with the help of precise location information. In addition, the risk of missing binding transport deadlines is reduced. Fleet scheduling has a complete overview of the location and condition of the transport fleets in real time and can thus intervene in time and reallocate time-critical loads to other vehicles if necessary. Ultimately, this also helps to avoid contractual penalties.

IT DOESN'T GET ANY LIGHTER THAN THIS! Last but not least, the weight of the axle also has an impact on fuel consumption. With the help of lightweight design options such as the BPW aluminium hub, the weight of the BPW Airlight II unit, which is already one of the lightest in the nine-tonne trailer axle segment, can be reduced even further. The saving results in a payload gain, so that CO₂ emissions per tonne-kilometre are reduced, giving an economic plus for the vehicle operator. With a mileage of 120,000 kilometres, 43 litres of diesel and 114 kilograms of CO₂ can be saved per year and vehicle and, depending on the goods being transported, more than 500 euros can be earned additionally.

ALWAYS PROPERLY UNDER PRESSURE! With the AirSave from BPW, you control and regulate your tyre pressure continuously while driving. The tyre pressure is constantly monitored and automatically adjusted to the desired pressure with a booster. In the event of major deviations in pressure, a warning light informs the driver that there is a puncture and he can drive to a workshop in good time. With a mileage of 120,000 kilometres per year and vehicle, as is usual in long-distance transport, 2,480 litres of diesel can be saved per year in a fleet of ten vehicles. This corresponds to a CO₂ quantity of 6,570 kilograms.

THE SMART SOLUTION FOR OPTIMUM PRESSURE. The BPW TireMonitor makes it easy to always set the optimum tyre pressure. BPW TireMonitor (TPMS) consists of individual sensors that are attached to the rims and transmit the tyre pressure to a receiver unit with an accuracy of up to +/- 0.3 bar. The data can then be displayed via an app or in the telematics platform cargofleet. The fuel-saving potential and other benefits correspond to BPW AirSave, provided the driver carries out checks and tyre maintenance.

The revision of the CO₂ fleet targets is due next year, and a tightening of the target values is considered likely in view of the almost unchecked progress of climate change. What is certain, however, is that from January 2024, with a transitional period of six months, the entire road train and thus also the trailer will be included in the VECTO calculations.

VECTO (Vehicle Energy Consumption Calculation Tool) is software that is publicly accessible via the internet. Its purpose is to output realistic fleet consumption figures for the most common types of commercial vehicles in the N2 and N3 classes and to reference these to a standard vehicle stored in the programme. Vehicle manufacturers are required to install more environmentally friendly technologies in order to achieve the CO₂ fleet targets. Solutions that are included in the VECTO calculation are therefore particularly attractive. These already include the following trailer solutions from the BPW Group:

  • Lift axles
  • Self steering axles (also in combination with ARC)

In our white paper "CO₂ and fuel consumption reduction in the fleet", you can also find out how modern trailer technologies contribute to the cost-effectiveness of transport operations and reduce fuel consumption and CO₂ emissions.
