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!
