Chassis cabs to get higher mpg

by David Zatz on

Federal agencies will propose tighter rules for efficiency in medium and heavy duty trucks (Classes 4-8), including Ram 4500 and 5500 chassis cabs. Preliminary rules are to be released by March 2015, with a final rule for the 2019 model  year unveiled by March 2016.

The 2014 model year marked the first fuel efficiency standards for trucks in this class, required by a law passed by Congress and signed by President Bush in 2007. The intent is to reduce fuel usage in the covered trucks by up to 20%.

The first set of rules, enacted in 2011 and working from 2014-2018, are expected to save truckers $50 billion in fuel costs (530 billion barrels of oil), at the cost of around $8 billion in higher vehicle prices. This is a hefty net savings, and should result in a slight reduction of America’s trade deficit and possibly lower diesel prices for other drivers. The largest fuel savings are targeted at “big rigs” (combination tractors).
