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

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.

Also the larger wheels.

I believe it's the larger wheels, not Max Tow.

I believed that too which is why I bought a set of Lariat take-offs. I wasn't able to detect an efficiency difference with different wheels.

Honestly I don't think I could detect a 0.1 m/kWh difference anyway. Disregard everything I've said.

Obviously.....

When you use tow mode, the extra cooling does lower range a little, but that's it, no impact when in normal mode.

I think 'hearing' from dealers is part of the problem. Dealers, or their employees, rarely own or drive a LIGHTNING, or any ev, for that matter, yet, they somehow have 'heard' that 'this or that' can cause an issue... why would they even SAY that? Are they trying to talk you OUT of a LIGHTNING?

Those of us who own, drive, and have an intimate relationship with our truck know that most of this 'I heard' hearsay is a bunch of malarkey... they talk with no real understanding or experience. Having a LIGHTNING in the dealer's shop bay is not true experience. People always 'say' things, whether they are true in fact, or not.

Sales motives are:

• Move inventory on the lot
• Move available inventory at region pools
• Find inventory for swap from affiliated dealers.

The least amount of effort to make the sale as quickly as possible!!

Unless someone has a technical diagram, I am going to use my preconditioning to see how much electricity I use I have it set to high temp
55* out side coldish battery
Truck set for 740 departure
7:21 peak 11.5 kw
7:22 drops to 2 kw
7:23 to 7:40 leave less than 1KW
don’t see like a PTC heater is kicking on I know it jumped to 11.5 because the truck was at 89%.

Yes, that brief peak load was the OBC topping up your HVB.

Like to see the "by the minute" snap shots a couple minutes after the battery returned to 90% SOC goal, I bet it's a lot less than the PTC values of around 5-6 KW

@TaxmanHog
Yep drops to less 2 kw then all the way down to less than 1 kw till I leave

Ignoring the lies most dealers will tell to sell a vehicle... Do the math.

The extra weight is negligible. Less than 1% weight difference from the added components, which translates to less than 1% range difference. Weight matters for acceleration energy cost, and we do more acceleration than most people believe (for example, changing direction on a wide curve highway is an acceleration even when done at a constant speed). But because F=ma is linear with mass, you'll see less than 1% change in energy cost due to the extra weight.

The extra cooling, when on, will draw about 5 kW. That can add up if you're hauling a long distance. Say you're towing for an hour in Death Valley in the summer...you'll need that cooler on and you'll use ~5kWh. Out of 130 kWh of battery on the ER, that extra use is about 3.8%, or about 6 miles out of ~150 miles range while towing.

Total range decrease due to having and using max tow is less than about 4% while towing in a hot environment. But it preserves long-term battery life.

You can gain that range back by slowing down a few mph. Once drag becomes dominant, the total energy cost to move the vehicle is proportional to speed cubed (aerodynamic drag introduces another multiple of velocity that's not accounted for in E=1/2m*v^2).
