Study estimates fuel economy improvements to US light-duty vehicles from 1975–2018 saved 2T gallons of fuel, 17B tons of CO2

Green Car Congress

A team from the University of Tennessee and the National Renewable Energy Laboratory (NREL) has the fuel savings due to fuel economy improvements over the past 43 years amount to approximately two trillion gallons of gasoline. Fleet-wide fuel economy gains produced large fuel savings. Greene et al.

Studies highlight effects of different gasoline components on fuel economy, combustion and emissions

Green Car Congress

Researchers at Jilin University (China) have investigated the effect of gasoline components on fuel economy, combustion and emissions in a GDI (gasoline-direct-injection) engine. The team subsequently followed up this first study with a second, exploring the effects in a PFI (port-fuel-injection) engine.

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

Green Car Congress

Because of the pandemic, there was a substantial reduction in 2020 in vehicle miles traveled. Overall , vehicle miles traveled in 2020 were down 13% compared with 2019. The results show that gasoline consumption per capita in 2020 was on par with that 55 years ago. Total consumption. Total consumption (millions of gallons).

MIT study finds fuel economy standards are 6-14 times less cost effective than fuel tax for reducing gasoline use

Green Car Congress

In a study published in the journal Energy Economics , MIT researchers have found that a fuel economy standard is at least six to fourteen times less cost effective than a fuel tax when targeting an identical reduction in cumulative gasoline use (20% by 2050). —Karplus et al.

EPA’s annual automotive trends report shows slight increase in fuel economy from MY2017 to MY2018

Green Car Congress

In the US, Model Year (MY) 2018 vehicle fuel economy was 25.1 In model year 2018, the average estimated real-world CO2 emission rate for all new vehicles fell by 4 grams per mile (g/mi) to 353 g/mi, the lowest level measured since 1975, when EPA data collection began. 0 g/mi—and highest fuel economy, at 113.7
