FEV’s two-stage VCR system; 5-7% increase in fuel economy using variable length conrods

Green Car Congress

Use of a variable compression ratio (VCR) could be one technology approach to reducing fuel consumption in highly boosted (e.g., downsized, turbocharged) gasoline engine, as operating an engine with higher compression ratios at low load can increase fuel economy compared to operating an engine with fixed compression ratio.

EIA projects decline in transportation sector energy consumption through 2037 despite increase in VMT, followed by increase

Green Car Congress

For the Transportation sector, EIA projects that energy consumption will decline between 2019 and 2037 (in the Reference case) because increases in fuel economy more than offset growth in vehicle miles traveled (VMT). This growth arises from increases in air transportation outpacing increases in aircraft fuel efficiency.
