Somebody asked, and it looks like a valid question:
What do all the acronyms mean?
Wayne Gerdes started this, he's big into efficiency, apparently with his syllables too. TLAs (Three-Letter Acronyms) appear to be a serious fashion with ecoheads. But I digress.
In no specific order
AD = Aerodynamic Drag
AS = Auto Stop. A hybrid feature that shuts the engine off automatically
FAS = Forced Auto Stop. Like above, but forced by the driver. Also applies to non-hybrids, but the TLA is the same.
FE = Fuel Efficiency
ME = Maximum Efficiency
SG = ScanGauge. A device that reads info from the engine control module and can provide real-time fuel usage data. Super-handy for driving habit alteration.
DWB = Driving Without Brakes. No, not really! But drive
as if you don't have brakes. Ease up on acceleration, start permitting coast-downs from way, way out. Using brakes means throwing away energy you've invested in getting the car up to speed.
EOC = Engine Off Operation. Continued driving after FAS. You're still moving, but the engine is now merely a passenger.
BS = Bump Start. Starting the engine by popping the clutch in gear.
ICE = Internal Combustion Engine.
DFAS = Draft-assisted Forced Auto Stop. Extending EOC by coasting along in the wake of a leading vehicle.
Highly Dangerous, not recommended
P&G = Pulse and Glide. Engine on,
pulse to an upper boundary speed, engine off (or shift to neutral) and
glide to a lower boundary speed. This is a proven effective technique for maximum FE, but maddening to other traffic.
FCD = Fuel Consumption Display. Like a ScanGauge, but factory-installed.
MPG = Miles Per Gallon. You already knew that.
YMMV = Your Mileage May Vary. The cliched and oh-so-true warning from the EPA that their mileage ratings were, in fact, bogus. Not so much the case anymore, and around here, they're wrong the other way: they're too low.
That's all I've got for now. If anyone wants to tack any on, go nuts.
