Model X Range

Is there any information on the range of the Model X?
I cannot seem to find it anywhere.

Are there different range models?


Tesla was explicit that they plan to use the same battery packs as for Model S (except for the 40kWh variant), see the bottom of this page:

The specified range for the Model S for these packs is 230 miles and 300 miles, respectively. The specification is based on a constant speed of 55 mph, thus it is (and must be) somewhat artificial. Based on experience with the Roadster, Tesla's specified ranges should be meaningful and actually achievable in practice, but YMMV.

For the Model X it was stated that ranges will go down approx. 12% by comparison with the Model S, due to greater weight and frontal area (greater aerodynamic drag). That would be 200 miles and 260 miles respectively. It seems to be implied that the difference in range between RWD and AWD is negligible, but I have not yet seen any explicit statements.

Has the MS range or performance been reduced by the frigid temps in the North-Mid-Atlantic states?

Yes, just like ICE cars, range, performance and efficiency is reduced in very cold temperatures.

On another thread, you indicated the Tesla battery temperature was regulated, implying that there was no direct effect of the environmental temperatures on the battery itself.

Is that implication correct? Does it not mean the effect of cold temperatures is just the effect on the workload and, perhaps, on the efficiency of the motors?

@Remnant - You're reading more into the answers I gave to the questions you asked. In the other thread, you stated that Tesla should have a battery warmer, it does (and a cooler as well). Above you asked if range or performance was reduced in the cold temperatures, they are.

What you didn't ask was if the cold had a direct effect on reducing battery performance. ;-)

I believe it's a combination of both the increased workload (colder, denser air, more rolling resistance on snow, etc.) as well as the fact that all heating to keep the batteries regulated must come from either the electricity coming from the connection to the grid if parked (and I'm assuming plugged in) or from the batteries themselves or motor while moving. This will undoubtedly have an effect on range just like in an ICE car of about 20%.

Here is some more great reading for this...


I understand the MX will have different range than MS. so with the stated loss of range in the 10-20%, one would expect the updated EPA numbers of the MS of 265 miles the MX range would fall 26-40 mile range from the 265 EPA numbers.

Please correct me.

No one knows for sure. Much speculation. No question some aspects that affect range will change. The cross sectional area of the car will go up. That will take range down (All this assumes the same amount of energy, 85Kwh) Weight will most likely go up. If it does that will also take range down. What we don't know is what the coeffient of drag will be. If less than .24, that of the Model S, then range will go up. If new battery chemistry is employed than you might see weight go down and/or energy go up, both of which will increase range.

Probably a 10% hit to range. I think 230 will be on the low side. Hopeful that little if any hit to range.

Other threads on the subject. Do a search via

My prediction is the base X will be 85 kWh and a 100 kWh pack will be optional. Hang with me, here's why:

The X will cost more $$ than the S, and I think Tesla won't release a more expensive ride with lower range. Elon said a larger pack is coming within a year, which corresponds to the X release date.

The Gen 3 base will use a 60 kWh pack to hit 225+ range. The 85 kWh pack will be optional.

Base Model S will eventually move from 60 to 85 kWh, with the 100 kWh available as an upgrade. AWD S option coming in a year, and the larger pack options allow for same or better range than today, despite AWD efficiency losses.

I made all of that up, so who knows how it will unfold. Bet I'm mostly correct...

Elon has always insisted on products that delight, over the top. Not sure of his words here. You can correct me.

What would make the MX do that for me, and I suspect most other potential buyers, would be to trade 0-60 time for range. Give me an MX with 400 mile range. Give me only 7 seconds to 60. After all, if you want to play supercar, buy a MS85P+. When you have 7 people in an SUV, going skiing, or to the mountains, you really do not need all that acceleration. Re-optimize the inverter for range. Get rid of the side mirrors. Use active boundary control to minimize drag. Two motors for better efficiency. Reduce the drag coef. Offer the 100 kwh battery.

These might offset the added weight, height, and awd which traditionally decrease range. Elon, Delight me!
