Does Higher MPG Mean Higher Fatalities?
The Union of Concerned Scientists even designed a minivan, the Vanguard, which uses only existing market technology to achieve significantly higher fuel economy and lower greenhouse gasses without changing the weight of the vehicle. For this hypothetical van, the group cherry-picked a package of technologies (like cylinder deactivation, turbocharging, and tires with lower rolling resistance) that they say can be applied to vehicles of all kinds without major cost increases.
