Battery capacity and pre collision assist

[Will K]

I have not been impressed with the distance I can get out of the battery, having followed Ford advice and selected the appropraire driver mode and having driven without any climate control and with only the radio and sat nav on I am getting approx 80% of the marketed 330 miles.( Sat Nav and radio use 1% ). It does not charge to 330 miles the max seems to be 313 and that is in summer as well as autumn. Also the pre collision assist is driving me nuts it engages even at speeds as low as 5 mph and this feature cannot be disengaged. Anyone else out there experiencing these issues? I always reset prior to use as advised by Ford. I have also had the windscreen and panoramic roof recall.

The issue is the European rating system which overestimates the range for EV quote substantially. In the US the same model is only rated for 270 miles (the US system is more accurate). Since it was sold in Europe, Ford, by law, had to use the European rating system.

Tom,

that is interesting, Ford have had me put the car in whisper mode, clear driving history each journey, not use accessories, getting the battery checked at the dealer who by the way can only identify fault codes not actually diagnose the battery, I have been driving at temperatures well over the 40 degrees Farenheight ranging from 10 degrees centigrade to 25 degrees centigrade and I I am getting between 260 and 280 miles which is consistent with what you have stated. It seems like mis selling to me as it is being advertised in the UK at 330 miles per charge. I have driven without accessories so have arrrived at my destination cold which is nuts. I am not at all happy with Ford who have actually done nothing to help other that send me advice that has no relevance or impact on distance available.

Tom my Mach E is the ER AWD version by the way advertised to deliver 330 miles

Pre collision alert can be averted by not tailgating.

Bev,

thanks, interesting reading, it seems other have the same issue whilst some are getting close to the advertised distance, I am getting 2.8m per kWh, buy a mustang and drive it like a pony seems to be the answe and how to advertise the car. I have also kept to the speed limit and not accelerated fast and can only increase the distance to 3.0m per kWh without much traffic in ideal driving conditions but as I cannot charge to 330 miles to start with I have a problem.

Rick thanks but I have not been tailgaiting but it engages when driving less that 5 mph at junctions approaching the car in front and it engages when cars enter the opposite carriageway and come towards me when there is not a risk of collision, perhaps having a car feature that is so sensitive to a mass in front is not a useful feature and whilst it might help me by picking up the next extinction meteor approaching earth I think NASA would have more use to it than me.

Either your vehicle needs adjustment, or you're experiencing things other than we are. We have had alerts when the vehicle in front of us takes a turn more slowly than we expected them to, otherwise no issues.

There's no problem. The testing cycle in your country set's unrealistic expectations.

First, the WLTP mandated testing cycle that achieves 330 miles is based on an average speed of 29 miles per hour, weighted for city driving not highway. Unless you have the about the same average speed you won't come close to the testing cycle efficiency results. (This is a government mandated testing cycle, not Ford's choice.) So blame the testing cycle for your expectations. Look at the US EPA ratings for the same configuration, your results should be closer to that testing cycle than WLTP.

Second, the GOM is always displays a pessimistic range estimate (and it's only an estimate). The weather is turning colder this time of year so your displayed range will decrease too.

Rick, thanks the pre collison assist (PCA) has not engaged whilst driving in traffic wher I manitain a sensible distance from the car in front and yes it has engaged in similar situations to the one you have stated where the car in front manouvres slowly but my point is I am in control and already slowing or braking and the intervention of the PCA is unnecessary and unhelpful. I will ask the dealership abut adjustment but I would expect that as Lane Keeping can be overridden and stopped the same should be the case for PCA

 

[RickMachE]

I don't believe it can be overridden, stopped, or adjusted (except to specifications).

Edit - to clarify, there are options that can be adjusted. The system cannot be turned off. You can adjust some things:

- Change alert and distance alert sensitivity to one of three possible settings.
- Switch distance indication and alert on or off.
- If required, switch automatic emergency braking on or off.
- If required, switch evasive steering assist on or off.

What I thought the OP was referring to was the loud alarm, and the big warning that comes up when the system determines a crash is imminent. That is what cannot be changed.

This doesn't make sense. Unless it is crazy cold, I get significantly better consumption in traffic than not. Being stopped or moving slowly uses much less energy than highway speeds. Even in my GT I can get 3mi/kWh or more unless I drive like a maniac or run the heater.

As others noted the problem is the way the EU rating system works. Ford has done exactly what they were supposed to and rated it based on that system. Others do the same thing. No vehicle ever achieves the advertised range because the system is flawed and not realistic to real world driving. Not Ford's fault. Keeping to the speed limit doesn't matter. We have 80mph speed limits here which will net 2.4mi/kWh or lower at those speeds.

I thought you could turn off the collision warning, but if you can't then turn the sensitivity to low. It will engage at low speeds if it thinks you're going to possibly hit the car in front of you. I have actually had this save me once when I thought the car ahead of me started driving and I was distracted. It slammed on the brakes to avoid me rear ending them. You likely can turn it off with FORScan though if you ever wanted to.

Make sure your tires are the correct pressure....but the cold will kill range. Even 40 degrees kills it. Just how EV's are, no getting out of it. Some with heat pumps are a little bit better in the 40-60 degree F range but still it's extra energy consumed.

The problem is the car doesn't know sometimes if you are in control. So it assumes you aren't. All it knows is what it's sensors/camera tells it based on how it is programmed.

if you are slowing down without the brake (1pd or just L regen) it doesn't actually know if you are paying attention. When you put your foot on the brake it assumes you are paying attention and doesn't engage - at least that's how I've experienced it.
