MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. We think that the way to enable the use of electricity in these vehicles is with a plug-in hybrid.

Audi testing find e-ethanol and e-diesel produced by Joule often perform better than conventional counterparts

Green Car Congress

Audi testing of synthetic ethanol (Audi e-ethanol = Joule Sunflow-E) and synthetic diesel (Audi e-diesel = Joule Sunflow-D), produced in partnership with Joule ( earlier post ) in a pressure chamber and optical research engine has shown that the Audi e-fuels often perform better than their conventional counterparts.
