From idea to innovation the betterflow story from idea
to innovation


BETTERFLOW improves the aerodynamic behaviour of semitrucks. The patented Rear-Wing System decisively optimises the air resistance; the cDvalue is thus reduced by approx. 9%. The worldwide unique wing system opens automatically as soon as the truck reaches 60 km/h while driving. This changes the air flow at the rear of the trailer. The vehicle can move forward more easily, fuel consumption is reduced and, as a result, the costs for companies are also reduced.


With additional streamlined add-ons, BETTERFLOW further reduces air resistance and thus exploits the entire aerodynamic potential of the trucks. The CONSEMS (Consumption Emission Simulation) tool from BETTERFLOW precisely calculates the fuel consumption of your fleet and at the same time shows your savings potential and economically reasonable measures for improvement.


More than ten BETTERFLOW employees at the company headquarters in Aachen have been perfecting this environmentally friendly innovation for about six years. Dr. Rainer Buffo and Ingo Martin came up with the idea for the effective wing system while they were studying aerospace engineering at RWTH Aachen University. The two engineers were looking for a practicable solution for sustainable, environmentally friendly mobility.


After years of invention and research, they developed BETTERFLOW, a well-engineered product that operates reliably and maintenance-free. The trend-setting Rear-Wing System reduces the expenses of logistics companies, decreases emissions and thus protects the environment – all in line with the inventors’ intentions.

BETTERFLOW to support TUM in the 'Truck 2030' project

In the project “Truck 2030” the TUM University is working on an economical and climate-friendly vehicle solution of future long-distance road haulage, based on transport scenarios in 2030. With partners from industry and science, the TUM considers approaches in fields of lightweight construction, energy recovery and aerodynamics. As official project supporter, the rear of the Truck 2030 is based on our patented rear-wing system. More proof of BETTERFLOW pioneering aerodynamic optimization of semi-trailers.

business & testing


We are not only responsible for ourselves, but also for our environment and future generations. This applies to private individuals as well as to companies. A principle of economic action is the economical use of financial resources and the careful handling of production factors.
The public is increasingly interested in the sustainable use of resources and the socially or ecologically exemplary behaviour of companies. Corporate Social Responsibility (CSR) has become an indicator for the sustainable development of society and the economy.

BETTERFLOW is GS1 Germany Solution Partner and member of the GS1 initiative Lean and Green.

The participating companies have agreed to reduce their emissions of greenhouse gases and in particular CO₂ in the logistics processes by 20% within five years. BETTERFLOW’s aerodynamically optimised products, which reduce diesel consumption and thus also CO₂ emissions, are a good way of doing this.
