ORNL study quantifies fuel economy costs of common driver practices and vehicle alterations

Green Car Congress

In addition, two minivans were subjected to coastdowns to examine the similarity in derived coefficients for two duplicate vehicles of the same model. The SUV, a 2009 Ford Explorer with a 4-liter V6 engine, was also tested while towing an enclosed trailer. This may happen, for example, when a vehicle is pulling a heavy boat up a hill.

NRC report finds significant number of near-term technologies could greatly reduce fuel consumption in passenger cars

Green Car Congress

Based primarily on an EPA teardown study, the committee’s estimates of the costs for turbocharging and downsizing range from close to zero additional cost, when converting from a V6 to a four-cylinder (I4) engine, to almost $1,000, when converting from a V8 to a V6 engine. The practicality of full-performance battery electric vehicles (i.e.,
