The payback time is highly dependent on the segment and the market. Electric trucks can also open up new business opportunities. Their economic viability will increase over time with economies of scale and as different segments mature. For example, incentives and legislation are making the use of electric trucks for inner city distribution and refuse collection much more attractive. The low variable costs will lead to greater profitability the more the truck is used. Once the high initial investment has been paid off, the low variable costs of electric trucks will have a positive impact on profitability.
