Taller Tire Test (5.7% MPG increase observed on Honda CR-Z @ 55-65 MPH)   Taller Tire Test (5.7% MPG increase observed on Honda CR-Z @ 55-65 MPH)
The purpose of the test was to determine whether larger diameter tires, which result in lower engine RPM and higher load for a given speed, can improve gas mileage. The test car has a 6-speed manual transmission. At highway speeds (55-65 MPH), the larger tires gave a 5.7% average increase in MPG. The engine ran about 200 RPM lower.

Arduino controlled automatically actuated grill block   Arduino controlled automatically actuated grill block
Here's the idea: Use an arduino to monitor temperature and output commands to a simple electric door lock actuator. This actuator will close and open the grill block door. Originally started back in 2009, this project sputtered out when the first design didn't work well. The 2012 redesign looks much better.

Stricter EPA testing for 2017 model year - be careful making comparisons   Stricter EPA testing for 2017 model year - be careful making comparisons
EPA fuel economy testing has changed because of manufacturers who were caught using "erroneous" (haha) coastdown methods for measuring aero drag and mechanical resistance. As a result, many 2017 vehicle ratings are lower than the previous year.

Orbywan says: "About a month ago I decided to build a boat tail for my 95 E-350 Ford 25 foot turbo diesel Class C motor home. I read the aerodynamics study NASA did at Dryden Air Force base back in the late 60ís on the squared off E-150 van about 20 times, as well as several other studies, drew up some plans and three weeks later and some serious sweat the prototype is done and tested."
