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.
