Gasoline consumption per capita in 2020 was on par with that in 1965

Green Car Congress

Gasoline consumption per capita was calculated using the population estimates in the ProQuest Statistical Abstract of the United States. Not coincidentally, the first Corporate Average Fuel Economy (CAFE) standards for new cars and light trucks became effective with 1978 model-year vehicles. Consumption per capita.

Study finds air quality models significantly underestimate traffic as source of NOx in Europe

Green Car Congress

Traffic contributes more to NO x emissions in Europe than previously thought, according to a new study by a team at the University of Innsbruck. Using statistical methods, the scientists infer emissions from these data within a radius of about one kilometer of the measurement location. We record 36,000 data points per hour.

However, increased dilution leads to increased combustion instability resulting in reduced fuel-economy benefits. In the past, researchers had to rely on highly simplified engine models to simulate the thousands of consecutive engine cycles needed to study the cycle-to-cycle variability with statistical accuracy.
