Intrepid blogger Ben recently attended a GM engine technology demonstration (HCCI) and got to talking to the engineers about driver feedback & MPG displays:
...my first question for the GM techs was whether or not something indicating HCCI mode or gas mileage would show up on the production models of cars equipped with this technology. I donít know quite what I expected for an answer, but it certainly wasnít the one I got. Paul Najt seemed to like the question, and came to the same conclusion that Iíve long had, which is that fuel economy can become like a game.
The irony of GM's product line to date is that they've reserved MPG displays for their middle and upper product lines. People who have chosen their smaller, less expensive - and less thirsty - new vehicles are driving "blind".
GM's obviously not alone on this front, but hopefully pressure from companies like Toyota & Nissan, who have announced they're putting FE displays in ALL their models, will spur others on to do the same.
