If you haven't tried hitting the "N" button while driving your Roadster v2.5 - try it! Not accelerating never felt so fast! If you've read about how low friction the Roadster drivetrain is, but don't believe it, get onto an empty road and while moving at, say, 40MPH, shift into Neutral. It's pretty darn amazing. A Roadster in neutral just coasts and coasts and coasts. So, besides the non-rush rush, what's interesting about this? Hypermiling. A fellow Roadster owner pointed out to me that while regen is great, true hypermilers want to coast. The thinking being that regen only gets back around 66% (and that's on the generous side) of what you expended, but you'd get more back by letting your car pick up speed going downhill and then continue to coast until the speed drops too low, and then provide power. In other words, the power stored in the moving vehicle is more efficient than converting that power into battery juice which is subsequently used to make the car continue to move. While popping into Neutral is fun and easy, getting back into Drive can be a bit jarring. I need to play around some, but it doesn't appear that you can "rev the motor" by pressing the accelerator pedal while in neutral, but I need to see if pressing the pedal reduces the regen so the transition back into drive isn't so jarring. And, while this technique might save some watts, it surely seems like it would create more wear and tear on the drivetrain. Anyone else experiment with this?
