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.

Feature: Are Eco-Friendly Cars Expensive to Own?

Clean Fleet Report

A study conducted by a team at the Massachusetts Institute of Technology (MIT) compared the lifetime costs of owning a gas-powered vehicle versus that of owning an eco-friendly vehicle. Hybrids and EVs can cost you less. Moreover, electric cars use regenerative braking that reduces wear and tear compared to traditional brakes.
