What kind of mpg would I get w/ 300h in Sport mode all the time?
Hello,
I was curious if anyone left their 300h in sport mode for an entire tank of gas and checked their MPG? I admit I have a lead foot and wear very heavy shoes.

The 'mode' selector simply controls the distance the accelerator pedal needs to be depressed in order to achieve a specific RPM. For example, 3000 RPM in ECO mode has the same amount of power as 3000 RPM in SPORT mode. But you have to push the accelerator down a lot more in ECO mode than in sport mode to achieve 3000 RPM.
I get pretty much the same fuel efficiency in all 3 modes.

First, there is a definite change in transmission shift points depending on which mode is being used. Also, there is a change in how much the air conditioner compressor is being used depending on the mode. I suspect that there are also other differences that are less apparent.

Lesz, the OP is referring to the 300h where there are no shift points in the transmission.
Not sure about the a/c, you may be right. The bottom line is that I get pretty much the same fuel efficiency in all 3 modes. A lead foot will yield pretty much equally poor FE (poor for the 300h).

probably 80% of my miles are on highway and I have heavy shoes too. still getting 37+mpg / tank.
but I do try to coast. I'd probably be around 35 if I didn't look at the mpg graph.
I use the go peddle when I need to, but still watch the trip mpg graph, its a little game we all play.

Bill, on with you on this too. I'm getting between 38-39 mpg without really paying attention, but I do try to coast as much as I can. I've changed the mileage bar graph on the Nav screen for maps/radio, but using the smaller dashboard panel's FE readout. This lets me keep half an eye on my current FE, so I don't go hog wild.

Lesz, while you are technically correct, the car's power is basically the same at any given RPM regardless of the mode. In ECO and NORMAL modes, you have to push the the throttle more to get the same RPM level/power as in SPORT mode and while in SPORT mode, you have to go lighter on the throttle to get the same RPM level/power as in ECO and NORMAL.
So if you are going up a hill and need 3000 RPM for sufficient power, you may have to depress the accelerator pedal 1" in SPORT mode while you may need to depress it 3" in ECO mode (I am guessing at the amounts - I have not measured) - the amount of power at 3000 rpm in each mode is the same.

Sport mode will in most cases suck your MPG. My 12.2 mile commute to work yields around 40 mpg traveling no faster than 45 mph on average. In Sport mode this morning it dropped to 33 mpg, wanted to give you real world feel.
Sport mode will remap the throttle, provide more power to the climate control system AND double the voltage at the inverter where you will see your battery drain a whole lot quicker. The battery takes a hit in Sports mode on two fronts.
You can keep your mpgs up in Sport mode by pulsing and gliding but it makes for a very uncomfortable ride.
