Max tow = range impact? Told by dealer...

[SpaceEVDriver]

Yes I agree the mass is negligible. I've even seen some you tube tests of having 1500lbs or something in the bed, with minimal aerodynamic changes, and the efficiency barely moved. Like under 10% worse.

As for the power consumption while it's on, I guess that's the real source. And as a non owner (yet), I can't find good reliable info about how these systems work or not.

The dealer was implying that the cooling/temp mgmt systems ran all the time, alongside the regular thermal mgmt system, and that was the cause.


Regardless, it sounds like the truck were gonna get brought in will NOT have the max tow.

But it will have the AT tires. So, @RickLightning, curious if you have a comparison for how bad it is?


Thanks all. These boards are so helpful for the EV scene since dealers are seemingly near useless

I have AT tires on my '23 Lariat ER. I drive through the Mojave Desert about once a month. My last trip was when it was up to 120 ºF during the drive. Doing 70-73 mph on the freeway, I got 2.8 miles/kWh. That translates to around 360-370 miles range. YMMV, of course.

At 70 - 73mph, I have never gotten anywhere near 2.8. You're getting it because you're on a flat road, with no stock and go, and it's warm.

I've theorized that Max Tow is the reason the Platinum's EPA range is 300 instead of 320 for all other trims. Max Tow is standard on a Platinum and optional on other trims. I've not verified this in any scientific way.

Larger wheels are the issue. I have a max tow Lariat…326 mi range at 100%. Irl with freeway driving its probably closer 300. I’d expect the same drop from the Platinum down to 280 or so.

Wow that's wild, in cdn terms that's 4.48km per kwh...at the 131 kw capacity gives a theoretical range of 580kms, above the official one of 515kms. That's like 22.3kw/100km....which I got around town but not hwy. Good work! Based on your time and distance your avg velocity was 67mph.

When I did a hwy test with the test drive truck I had, I got way less efficiency. I was doing 115-118kmh so about the same as you, and got 37kw/100km...or about 355kms range. Using 90% for driving, 5% for climate, 2% accy and 3% ext temps (was 7-8°C).



Hope I can hit numbers like yours with this!!

Full disclosure: This particular trip, which I do once every 1-3 months includes a loss (and then gain) of elevation of about 6800 feet (2100 meters). On the way down I get 2.8-3.0 miles/kWh (22.2 to 20.7 kWh/100 km, as shown) and on the way up I get 2.0 to 2.2 miles/kWh (31.1 to 28.3 kWh/100 km). So my average is around 2.4 miles/kWh (25.9 kWh/100 km) on this particular trip of 1100 miles (1770 km).

On some of these trips, the winds generated by the interaction between extremely dry and hot desert and the cool/wet coast can cause me a large loss in efficiency, sometimes bringing one long leg down to about 1.7 miles/kWh (36.6 kWh/100 km).

My lifetime (7500 miles; 12100 km) is 2.4 miles/kWh (25.9 kWh/100 km), but I don't drive this around town much--we have the Mustang Mach-E for local driving and after 43,000 miles (63,000 km) of mixed freeway/local driving, we are averaging 4.1 miles/kWh or 15.2 kWh/100 km).

We do get "cold" here, but not BC "cold." Cold weather performance will be less, potentially by quite a bit.

Great data, thanks! And that's all with the AT tires?

I'd be pretty stoked if I could get lifetime avgs on the lightning to be sub 26 kw/100kms efficiency. Heck even sub 28. Electrical prices here would put that at about $3-$3.50/100kms cost of fuel.

Tad bit better than the 12-13L/100km ($20-$25) cost of fueling the ICE version!

All with stock Hankook AT2 275/60R20 tires--note that these are not the BFGoodrich AT tires that some trucks were shipped with.

I run them up near the top of their pressure profile, rather than at the recommended pressure on the door jamb sticker. At some point I'll buy a set of lighter-weight 18" wheels and street tires for spring/summer/autumn/road tripping and keep the 20" wheels for snow/winter tires.

Hi all

Saga continues for me to actually get my hands on the lightning that I want...

But in the meantime, I have had a couple dealers tell me that they've had customers complain that purchased the max tow package. They said that the extra cooling equipment in that uses up a bit of extra energy and adds a small amount of weight of course.

Has anyone heard any kind of concrete evidence about this one way or another? Like maybe had a friend that swapped from one without Max tow to one with it or something or just heard other people commenting on it? I can't tell if it's just the sales people telling me that so they can get me behind the wheel of it or not. Personally I don't think I would actually need to tow anything heavier than 7500lbs, but I had thought for later resale value that I may just get the truck with it.


I'm just interested to know if anyone has heard other info that would confirm this or not. Or if @Ford Motor Company could confirm If there is even any amount of range difference or efficiency difference between Max tow or not?

It kind of makes sense to me that there would be..

Your desired cabin temperature will have more affect on range than ant supposed range loss for the package.

I have a 2024 Platinum with Pro Power and Max Tow with the stock on 275/50/22 General Grabber HTS60 tires inflated to 49 PSI.. I drove from Radford VA to Centreville VA (240 miles), I didn't use the heat pump, just seat heaters and steering wheel heater, drove 70 to 75 MPH most of the way, did some tractor trailer drafting too. Overall 2.3 miles per kWH, which I felt was pretty good with ambient outdoor temps tonight range from 58 degrees when I started to 38 degrees when I arrived home.

I believe Low Rolling Resistance tires and lighter wheels will have a bigger impact than the Max Tow package, this is my 6th EV, I always go with the lightest fully forged wheel and lightest EV rated tires I can get. Right now I am leaning towards the Atomic Wheels (30 lbs) in 20 inch and Pirelli Scorpion AS Plus 3's (38 lbs) would prefer an ECO Focused tire, so still trying to find the right mix for my 2024 Platinum with these ridiculous 22 inch wheels. This truck is a street only vehicle and I have another off-road truck purpose built with 33" (Nittos), but that would kill the range on this already overweight truck.

The setup above would drop 20 lbs per corner, static 80 lbs total and rotational weight reduction of

Decrease of 1.1 lbs rotating weight = increase in 1 WHP
