Wayne Brown is a previous member of Priuschat who has been keeping a low profile of late. But that doesn't mean he's been idle. He had previously developed a simulator for Prius that could predict your fuel economy under a plethora of driving conditions. Now he's redone that project in a new and improved format that will work with any vehicle. Main Currently only available for Mac, but will have a version for iPhone, PC, etc. in the future. There are also future plans to build in elevation data for specific routes and such (which will be a boon to EV drivers). Mac Store Link - Currently $5 until the end of the month. If you have any questions for Wayne about the program you can reach him at : [email protected]
