We live in interesting times, where technology continues to bring overall savings in the total cost of operating vehicles. Many of the advances made in reducing fuel consumption and minimising emissions levels have resulted from a genuine concern by governments about the rising levels of pollution leading to avoidable illness and premature death of their populations.
Europe and parts of Asia have already introduced Euro 6 emissions levels, with the Obama administration responsible for funding developmental work amongst US truck makers to improve vehicle efficiency and match, or exceed, the advances made in Europe. When the investment stops, developmental advances slow down, unless financial constraints continue to force the need to find better solutions.
