My apologies if this has been covered already, as I'm new here.
My current vehicle uses an ICE with a manual transmission. Being curious about hype-rmiling techniques, I occasionally disengage the gearbox an let the car coast. At other times, simply letting go of the gas pedal in a high gear will cause the car to slow down over a long period of time. Both of these techniques will increase the measured MPG average according to my car's computer.
My concern involves something I read that the Tesla Model S would immediately engage the regenerative braking system if the gas pedal were let go. Is this true? Can one not coast in a Tesla?
Have there been studies done regarding the cost/benefit ratio of immediate regenerative braking vs coasting?
If this is true, I would strongly recommend your software includes an option for the customer to select their desired behavior.
