Model X LR+ is advertised with 351mi range, while the Performance version 305mi. What parts are different between the two? If you drive them both the same (say, nice and easy) why would one get more range than the other?

I disagree with the motor as the reason for the mileage difference..Because the rear motor is larger and less efficient in the performance model.
They probably come with different tires too which are direct rolling resistance changes.
Don't buy into the idea it is rim diameter like most folks here want to believe tires make a meaningful difference.
Rim diameter isn't the issue, contact patch is. Usually a bigger rim is wider and more rubber. The motor def is the mileage difference for X/S - not as much for 3.I disagree with the motor as the reason for the mileage difference..
There is a Canadian Company Ingenext that has made a plugin module for the Dual Motor Model 3 for $1,100 that increase 0-60 to 3.8 seconds (a plugin Module) BOOST 50 and for $2,250 upgrade 0-60 3.2 seconds (a software upgrade).Ghost Upgrade It has nothing to do with the Motor it is software. The Rotational Weight of the 21" Wheels, increased drag with the Rear Spoiler and other items. If you think that the downforce created by that rear spoiler does not come at an loss aerodynamic I think you are wrong. The Model 3 Performance and AWD Motors are the very same. Not my cup of tea, but for those who are taking their Model 3's to Track Day...

Besides a few other folks already wrecking most of your argument, I want to touch on the rim weight thing.I disagree with the motor as the reason for the mileage difference..

The Performace Version of the Model Y without the PUP Package only has a 1 mile dower range than the AWD Model Y... It is not until you add the PUP Package before its range drops to 280 Miles...
The wheel weight is only part of it, the tire resistance is very significant. Regeneration doesn't recover all of the extra energy used to accelerate the heavier wheels though and you expend even more energy fighting the heavier rotational mass in corners. I could feel the difference in stopping distance between my P100D w/ 20s and a loaner P100D w/ 22s. I actually found myself hitting the brakes because I'd overshoot my intended stop until I got used to driving with the 22s.Besides a few other folks already wrecking most of your argument, I want to touch on the rim weight thing.
On an ICE once you waste excess energy accelerating a heavier rim it is wasted, BUT in an EV with Regen you have the opportunity to recapture much of it, so I believe the impact of wheel weight is grossly overstated around here. Plus it would only matter in stop and go driving anyway as steady state highway there are not the quantity of acceleration events to waste energy accelerating a heavier wheel. Highway, wheel aerodynamics are critical to range stretching, that is why Tesla goes ahead and uses heavy aero wheels. If weight alone was a meaningful factor they would simply add a forged range wheel, people would pay enough to make it worthwhile.
Performance tires, larger wheels, different electronics in the motors, etc. This is actually a somewhat weird question because if you purchased a legacy performance car you would just expect to get less range. No kind of car can beat physics.Model X LR+ is advertised with 351mi range, while the Performance version 305mi. What parts are different between the two?

This is the first time I've heard that the rear motor is different between the LR and P models. If that's true, that could explain a lot, but I just found a thread over in the Tesla forums that say the motors are the same. I also get that tires can make a different due to rolling resistance, as you pointed out. I just checked the Tesla Model X order site and the wheel sizes on the stock LR and P models are the same at 20".Because the rear motor is larger and less efficient in the performance model.
