Tesla Model X 75D, 90D & P90D – City/Highway/Combined EPA Ratings



While those interested know the official EPA ranges figures for the Tesla Model X 75D, 90D and P90D, here we present the calculations in a broken-down format in calculating the EPA’s final ratings.

From left to right in the chart below we see city, highway and combined ratings for the 3 versions of the Model X.

Of interest is that the 75D version isn’t rated all that much lower than the higher-spec and much more costly 90D and P90D versions.

EPA Ratings For Model X

EPA Ratings For Model X

Unlike the refreshed Tesla Model S 90D, which goes for over 300 miles on the highway, the 90D Model X only gets a highway rating of 262.7 miles.

Aerodynamics and weight definitely come into play here. Even the P90D Model S gets a highway rating of over 280 miles on a charge, compared to just 252.7 miles for the P90D X. So, if range is the most important factor for you, then the S has a significant advantage in all versions.

Actually with its lowest Cd, the Model 3 will likely become the Tesla with the longest range when equipped with the larger battery pack. That will be exciting to see. It will sure have 300 miles but will it hit the 400 miles in some versions?

The issue isn’t if there will be a Tesla with a 400 mile range: it’s what year it happens.

Well, I am not so sure with Tesla because in an interview of Elon Musk I saw back recently he said the Tesla could do a 500 miles car right now but that they didn’t do it because it would be inappropriate. That’s quiet strange but if they can do 500 right now, then 400 would be kind of easy. 400 miles would be a major tipping point for the market and would likely surprise Tesla even more than the Model 3 reservation numbers. I think they don’t quiet grasp what that 400 number mean to people, otherwise they would rush for it more fervently.

IIRC Elon meant that they could do a 500-mile Model S, but it would be super heavy and the batteries would take space from other things.

The retrofit 3.0 Tesla Roadster is capable of over 330 miles, which I guess people often forget, already exists. 😉 400 miles isn’t such a stretch of the imagination:


But it will cost you a pretty penny…

Well it would add 181 Kg of cells plus a bit of reinforcement, but that would still be only 10% of the present car weight. Since driving long distance is rather at higher speed the aero represent 75% of the energy and roll related to weight only 25%. With a 10% extra weight that would change the energy consumption per mile of only 2.5% which is negligible in regard to the 33% increase in battery energy.
To get that extra energy you can scavenge the frunck or other places but there is a better way in simply replacing the 18650 cells with 18870 cells. They would take the same surface area and only 22 mm more thickness which can be accommodated by adapting the suspension height. The 18870 cell is not produced but there is no reason why it couldn’t be. The result would be a 400 miles Model S 120D, right now instead of years away.

Likewise for the Model 3 instead of using the 22650 cells, I would use the 22870 cells.

not many people need a 400 mile car

Not nearly as butt-cramping, bladder-stretching numbers as the S90D, but impressive nonetheless.

On my 3400 mile trip it was ample and gave me plenty of stops for snacks, bathroom breaks, and meals. SuperChargers were about 125 miles apart.

There are expectations that the S100D will be out soon.

Don’t see it happening before the Gigafactory Christening Party on July 29th, which is (co-incidentally) 9 days after the new Battery Production Equipment from Panasonic was scheduled to be installed.

When you compare S with X, and the various battery sizes, the range does seem anomalous.
e.g. with the X the 75D has almost 20% less battery than 90D, but the 75D range penalty is well under 10%.
This doesn’t seem to correspond to the weight difference alone… and I’m not sure the same thing happens for the S.

I’m wondering if Tesla is gradually ending the practice of giving battery sizes as total battery size, and instead starting to quote available battery size… and so the 75D could actually be 75kwh available, whereas the 90D still quotes the total size.

I agree that something seems funny with the 75D rating – I don’t see how it can be so close to the 90D with 15 kWh less (nominal) energy available… at about 4 km/kWh, that should yield about 60 km less range, not 30 km.

Even more funny is the charging time of all model are the same.
So is it 75 kWh usable or what?

There are a couple of things I can think of, all related to the fact that the 75D is slower.

1) They have to be horsepower limiting the 75D to keep from dumping as much power to the motors. That should increase range.

2) I think the actual electric motors are different (can somebody confirm my speculation? I can’t find 75D motor specs). The motors might be built more more efficiency than pure power.

3) Gearing may be different. That could impact efficiency. (Again, I’m just speculating, and to quote Herman Cain, “I don’t have facts to back this up”)

I guess what I’m really saying is that there could be many other factors besides just the battery size that probably explain the difference.

Just passed by my first Model X in the wild yesterday… bright red. I think it was the P90D. Some July 4th visitor to our neighborhood. Still no license plate, so it’s brand-new 🙂

Adding the 60 and 75D to their lineup is a good move forward for Tesla. Most car makers offer a bracket of vehicle power. For example, the BMW 3 series has a set of engine offerings that roughly matches up with Tesla’s lineup:

S60 ~= 320
S75D ~= 328
S90D ~= 340
P90D ~= M3

BMW sells the 328’s the most, because it is a perfectly good car if you don’t want to pay extra for extra performance. The 75D now fills that slot for Tesla, where they now have a perfectly good middle of the line-up which can bulk up sales numbers.
