BMW "eco pro mode scam"
Discussion
Hello gang
just hit 25k miles on a 640d.
per fill up i have always seen 500/550 miles using 90% eco pro and probably 70% motorway.
for whatever reason the last fill up i have decided to test never using eco pro and comfort only
600 miles on the first try. same driving. nothing new.
why and how ?

In Eco Pro it backs the regen down to focus on more coasting - you have to drive to this style and leave massive gaps to allow for as much coasting as you can, followed by gentle regen.
In Comfort the regen is engaged much more quickly, so in normal traffic it's more aggressively using regen, hence a possibly slight uptick in economy.

More than just throttle calibration. It also reduces power of the A/C (which can allow stop/start to be operative for longer) and allows the car to coast when off throttle or brakes.
Switch between comfort and Eco Pro whilst rolling down a hill - it's like a brake has been released. This is only when it isn't charging the battery. You can see this on the dash graphic. A tap of the accelerator will often switch it from charge to coast when in Eco Pro.
Over 60k miles i've averaged 45 MPG in my 640d. I stay in comfort 99% of the time but there are a couple of long hills followed by flat near me where I switch into Eco Pro to try and roll to a roundabout about 2 miles away. Just about possible with no traffic. Good game
ETA - I get about 650 miles a tank.

Car is standard.
Coasting in eco pro makes a big difference , but doesn’t work if you use cruise and does require you to adjust your driving style a bit.
Eg there is a nsl road near me that goes to 50 for half a mile and then 40. Drop the cruise off just before the nsl ends and it will coast easily to the 40

I've had my 330d for 2 years and never used Eco Slow. It returns decent enough mpg in comfort mode that I've never felt the need to use it. Start/Stop has been disabled for 2 years as well as that is just completely annoying in heavy traffic.
I use XHP for the gearbox which detects slow moving traffic and doesn't drop to 1st, which makes crawling along smoother and more efficient.

Eco pro makes a few tweaks to the car to help boost MPG but if you drive it in the exact same way as you do in comfort then don't expect much in the way of savings. It will help you save fuel but you have to work with it too and adjust your driving style. For example, my old commute I would get low 40s MPG out of my 340i, if I used eco pro and adjusted my driving style to suit I could get over 50mpg. If I just pressed the switch and drove the same it would do bugger all, it's not magic.

Would you save the same fuel if you changed your driving style without pressing eco pro?I drive a M140 for work purposes. A lot of urban, dual carriageway etc
Eco pro offer the most benefit when you take time to learn how to have it coast. This though means paying an awful lot of attention to the gradient of the road, leaving large gaps and layering 'im in eco-pro' on top of how diligent you are naturally.
I can eek 29mpg out of the M140 using eco-pro. Circa 25 in comfort.
Forget all the other stuff eco-pro does. It's main benefit is coast.
Yes it saves fuel, BUT like the poster above, I agree the throttle response can be dangerous.

On my F30, it’s almost unusable:
1. The throttle map becomes awful, no response at all
2. It changes up way to early and lugs the engine - it will be in 8th by 50mph, doing about 1,100 rpm. On a petrol engine, this is not good. Then it really doesn’t want to change down for acceleration or getting up hill. You can feel vibration from the engine being under-revved.
And it makes very little difference to fuel burn in most driving.
