Why tinker with the engine when you can slap some skirts on your truck.....
We assume that, on the one hand, the effectiveness of the dynaCERT technology is significantly higher than that of trailer aprons but, on the other hand, the costs are also significantly higher than for trailer aprons. According to the Canadian Council of Energy Ministers, trailer aprons cost between 1500 and 2500 CAD and achieve fuel savings of between 4 and 7%. The dynaCERT technology has shown varying degrees of fuel savings, often between 9% and 15%. This technology, with a sales price of CAD 6000, would be roughly equivalent to the price/performance ratio of trailer skirts.
