Any interest in Vehicle Drag Calculator? (Android App) ajohn7211 writes: "I'm doing a project for a comp sci class and am wondering if anyone would be interested in a program for their Android phone (or tablet) that would help calculate the drag coefficient for their vehicle? It would involve inputting the weight of the vehicle and running a couple tests on flat road." By ajohn7211 - 15 replies

Geo Metro plug-in parallel hybrid EV - in progress Coyote X put an efficient Metro XFi drivetrain into a convertible Metro body, and added electric chain drive to one of the axles. Not satisified with the results, he recently began moving the XFi drivetrain into a mid-engine, lightweight kit car car chassis. He's planning a new approach for the electric drive components as well. By Coyote X - 150 replies

Project: Van+Large Trailer cd 0.36 to 0.23, CFD test Asias explains: "We are trying to substitute large 7 meter van (with 1200 kg payload) by a medium van + aerodynamic trailer. Before we were getting aprox 22 mpg at 65 mph, but we want go somewhere near 33 mpg." Using a CFD model (computational fluid dynamics), he documents a test beginning at 0.36 cd (only the van) resulting in a 0.233 cd with the trailer attached and gap filled. By ausias - 4 replies
