Gary, this may be simply a reflection of a software difference in the 2008 version, but I can get my 08 to go EV from D as long as I am:
1. 40 or just below
3. give the brakes one or two taps.
i.e., no need to be in L.
* the evidence from attempts to do this action seems to indicate that Ford has a little software routine involving some integral of deceleration rate and time.
Yes. Part of the trouble is
Yes. Part of the trouble is the FEH needs 42% or higher to shut down the gas engine. Doing P&G techniques in the 40% range... sometimes you want the engine to shut off at 41%, which is generally, not possible. Thus keeping a baseline of near 42% may be near optimal.
Tapping the brake
Tapping the brake pedal in "D" while decelerating to go EV was the first thing that was discovered by the early '05 FEH owners. The reason I use "L" is to pack a regen charge just before going EV. Early on I discovered that after the HV battery got to hot to accept a regen charge in "D" or "L" to go EV, shifting to "N" and tapping the brakes cured that problem. I found the same when the HV battery was to cold to accept to accept a regen charge in "D" or "L"to go EV, shifting to "N" and tapping the brakes works also. I use to get so angry that I could not go EV with the double tap in "D" or shifting to "L" because of this hot or cold battery issue till I discovered tapping the brake in "N". I almost never have a problem going EV under 40mph anymore. Of course if the battery is to full, "N" will prevent a run-up (engine braking) and allow EV by tapping the brake pedal lightly.

This story changes somewhat
This story changes somewhat with those that live in the real winter conditions. When the battery is too cold, shifting into "N" and tapping the brakes will not change anything. The cylinder head temperature needs to exceed 188 degrees and the radiator water temperature exceed 154 degrees for the first time after a cold start prior to any EV mode. Those of you with the Scan gauges can monitor this and report back. There is also the hybrid battery temperature that can play a role in allowing EV.
