Researchers propose evaluating alt fuel efficiency based on energy rather than volume; impact of ethanol on vehicle efficiency and GHGs

Green Car Congress

Relative changes in vehicle energy efficiency (VEE) (km/MJ) on ethanol/gasoline blends over those on gasoline for different blending levels. Several recent highly cited LCAs that have incorporated vehicle efficiency differences between gasoline and ethanol/gasoline blends could potentially be misleading. Click to enlarge.

Controlled Power Technologies Packages Its Switched Reluctance Systems in ‘RegEnBoost’ System for Enhanced Support for Downsizing

Green Car Congress

CPT says that the RegEnBoost system enables a typical family-sized car to achieve less than 100 g/km CO 2 with a 1-liter gasoline engine, but when required can offer the same lively performance and in-gear acceleration of a 2-liter naturally aspirated powertrain. The three components of the RegEnBoost system. Click to enlarge.
