PROPOSALS FOR PUBLIC ELECTRIC

TRANSPORTATION IN

MEXICO CITY

INTRODUCTION & BACKGROUND

A program to develop electric and hybrid vehicle

concepts at the National University of Mexico

(UNAM) started in 1993. The major effort during

this period has been aimed at producing original

designs of battery powered small busses and

delivery vans.

The most important developments include:
