英文文献摘要：
This study looks at the evidence about fuel economy and other truck attributes from VIUS, and provides implications for a dynamic baseline of improvements in fuel economy. We discuss the engine technologies and vehicle designs that potentially improve truck fuel economy. The combined effects of these advances are estimated as technological progress in our specifications. The rich information from VIUS about vehicle characteristics equips us to estimate the trade-off effects – how vehicle weight and engine power affect fuel economy.
