Hello,
first I like to introduce myself.
I am Ulrich Steinlechner from Germany and I developed a aerodynamic bumper to save fuel.
I testet a prototype at a w168 Daimler A-Class, because the shape of the car is typical for electric cars or other small cars. So a used car was also cheap enough for the experiment.
During the development, I made a lot of changes.
The result of measurements were different.
Fuel consumption during cruising speed were 9% to 17% less, but measurement in the windtunnel were 8% to 9% less drag.
Frum you, I like to get feedback about the difference of fuel consumption and aerodynamic drag.
What do you think about the design and wich car model should be the first for a serial produced bumper.
Kind regards,
Ulrich Steinlechner.
