Downspeeding and supercharging with transmission optimization can deliver fuel economy improvement over downspeeding and turbocharging

Green Car Congress

Researchers from Southwest Research Institute (SwRI) and Eaton have demonstrated the application of downspeeding and supercharging a diesel vehicle, in conjunction with optimizing transmission gear ratios and the shift schedule, to deliver a greater improvement in fuel economy than a downsped and turbocharged configuration.

Ford / AVL study concludes mid-level ethanol blend attractive as a long-term future fuel for use in optimized engines in US

Green Car Congress

A study by a team from Ford Motor Company and AVL has concluded that a mid-level ethanol blend—greater than E20 but less than E40—appears to be attractive as a long-term future fuel for the US for use in engines optimized for the higher octane blend. Downsizing/downspeeding. Volumetric fuel economy.

GFEI report finds improvements in average new LDV fuel economy lagging pace required to cut 50% fuel use for new cars worldwide by 2030; policy focus should be on emerging markets

Green Car Congress

Vehicle size, a key determinant of fuel economy, has shown a reduction in OECD countries, while the non-OECD trend is toward bigger vehicles. The analysis, an update of an earlier work using data from 2010 and 2011, found that the global average for light-duty vehicle fuel economy was 7.2 Source: GFEI. Click to enlarge.

Study Finds That Tripling US LDV New Fleet Fuel Efficiency by 2035 Through Evolutionary Change is Ambitious But Doable

Green Car Congress

Tripling US new light-duty vehicle fleet fuel efficiency by 2035 through evolutionary change—e.g., DeCicco’s analysis shows that optimizing internal combustion engines plus rising adoption of grid-free hybrids will enable new fleet fuel economy (unadjusted) to reach 52 mpg (4.52 L/100km) and 60 mpg (3.92

U Toronto team assess the climate trade-off between reduced CO2 and increased Black Carbon from GDI engines

Green Car Congress

The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing. A new study by a team at the University of Toronto has made a preliminary assessment of the climate trade-off (i.e.,
