Unsurprisingly, all of the highlights Exxon displayed in its sign about "Improving Energy Efficiency For Today's Consumer" at the Challenge Bibendum in Rio de Janiero, Brazil last week were small improvements related to getting more miles out of each gallon of gasoline. Exxon promoted better plastics that reduce weight and Exxcore DVA resins that make tires lighter. Not everything in the company's booth was simply about a bit less gasoline, since the cutaway "car" on display featured a 27 kWh lithium-ion superpolymer battery from ElectroVaya. Put all of these technologies together, though, and Exxon's press materials say, "the quest for better fuel efficiency could add up to big gains over the next 20 years."
The Exxon/ElectroVaya partnership vehicle displayed the Maya 300 NEV a year ago. That car was supposed to be a part of a new car-sharing program in Baltimore called AltCar, but nothing new has been posted to that site since the program was announced in June of 2009. The Maya 300 is supposed to come to market in 2011 and cost around $20,000-$25,000, but we're not going to stay up late waiting for news.
