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.

MIT study concludes V2G-enabled electric commercial trucks could offer lower total operating cost than conventional diesel fleet

Green Car Congress

A new study by researchers at MIT’s Center for Transportation and Logistics (CTL), concludes that electric commercial vehicles can cost 9 to 12% less to operate than trucks powered by diesel engines when used to make deliveries on an everyday basis in big cities and when V2G (vehicle-to-grid) revenue is incorporated.
