Researchers at Oak Ridge National Laboratory (ORNL) have quantified the fuel economy effects of some common driver practices and vehicle accessories or alterations—including underinflated tires, open windows, and rooftop and hitch-mounted cargo. Using a rooftop cargo box with the SUV decreased fuel economy from 24.9

Engineers at Toyota have developed an approach to applying the Atkinson cycle—used in the engines in Toyota hybrids since 1997—for engines in conventional, non-hybrid vehicles. The Atkinson cycle with a high compression ratio is a common approach that hybrid vehicle engines use to enhance thermal efficiency.
