The electric-powered Model X is more showy than practical.
It features rear doors that open up and out of the way, giving easy access to the rear seats.
But these massive doors take their time to open and close.
The huge windshield extends up and over the front-seat occupants, making the cabin feel airy and futuristic.
Buyers can opt for five-, six-, or seven-passenger seating configurations, but unlike every other SUV, the second row doesn't fold, which compromises utility.
Like the S, the Model X is very quick and handles well.
Ride comfort and noise isolation aren't as good as in the S, however.
The 90-kWh version we tested had a realistic 230-mile range.
As of 2019, the Model X came only with the 100 kWh battery.
The 75 kWh version was discontinued.
Other software updates brought a Sentry Mode which uses the car's cameras to monitor the car's surroundings.
Dog mode was also new and it runs the AC when a dog is left inside.
A display on the car's screen asks by-passers not to break a window to save the dog. Other changes for 2019 included Tesla's new Navigate on Autopilot software, which lets drivers choose whether the car can automatically change lanes without their input.
