BMW Eco Pro - Extra KM calculation

[ChrisThomas]

Hiya!

I often use the Eco Pro mode on my F30 3 series.

I get around 90km + indicated in the dash where it shows you how many extra km you get by using the eco pro mode.

I just wanted to know if anyone has any official way of knowing how this is calculated? Is it compared to the car being in Comfort mode?

basically it shuts down cylinders and tightens steering, auto stop/start allows all cylinders to shutdown and put aircon into reserve mode. You gain an extra 1km of fuel over 3km driven, at least this is what I've found in the X3, results may differ

it sucks fuel out of ANC fat cats wallets, instead of out the cars tank,

thats how Eco mode on a BMW works.

F30 does not have cylinder deactivation.

It saves fuel by dropping aircon performance, and lowers throttle response and limits KW of engine.

On my BMW tool max power is 80kw odd in eco, 100 odd in normal and full 135kw in sport mode.

Does the car become incredibly under powered when this mode is activated.

Yes it it does, I use it most of time as I am on highway mostly.

It bring my consumption down, I am on 6l/100km now use be 6.8L/100km.

Don’t you have a 320d? That’s crazy high...

Thanks guys. I know what all eco pro does. You can definitely feel the difference in the a/c when you switch back into comfort. My question was more based on what the calculations compare to, I’m assuming comfort mode?

I don’t understand why you’d buy a bloody expensive car with a really good air con and a decent engine just to cripple it like that. Unless you’re 100km away from the nearest petrol station with a range of 90km left.

If you want to sweat in summer and battle to overtake, buy an Etios.

I personally hardly use it as it is not fun to live with when you have a manual car - I have stalled a few times.

With that being said, it does make a difference albeit a minor one when I compare it to Comfort mode. Not worth the fear of stalling and taking a lifetime to get to 60 though.

The AC still works quite fine in Eco Mode, and you have all the power you want on kick down it's just a case of pressing the button under the accelerator... It kinda give you the best of both, 400 nm of torque when you want it, and 4.3 L/100 consumption when you're driving normally....
