Tesla discontinued all 75D, 100D, and P100D naming conventions in favor of a more simplified series of stand-alone packages and options for configuring the Model X specifically to your needs.
The Model X comes in a simplified set of configurations, with a list of options to upgrade where desired. A base Model X configuration is claimed to be able to hit 60 mph in just 4.7 seconds although Tesla doesn't brag about a specific horsepower number. Model X Performance models quicken the pace to 0-60 mph in only 3.5 seconds, and for a cool $20,000, Tesla will unlock "Ludicrous" mode, launching the Model X to 60 mph in 2.8 seconds. Both of those figures are staggering, making both models one of the fastest cars on the road. A single-speed transmission is all that's needed to transmit that power to the road, since unlike a traditional gasoline engine, electric motors make plenty of power all the way up to the redline.
The two challenges electric cars must overcome have traditionally been lack of power range per charge. Range for the Model X is a claimed 237 miles for the base model. The more powerful "Extended Range" has a broader capability of 295 miles. As part of the deal, drivers get access to Tesla's ever-expanding network of "Supercharger" fast charging stations. With these stations placed across the United States, owners may plug in their Teslas to recharge for no additional fee. Tesla claims that about 20 minutes at a supercharger station will charge the batteries about half way.
Standard features on the Tesla Model X include most of the basic luxury SUV amenities, though several features stand out. The so-called "Falcon-Wing" doors might be the most talked about feature on the Model X. The front doors open as any normal car door would, but the rear doors open up and out of the way, folding in the middle to avoid touching any adjacent cars. The advantage is a generous access into the vehicle, making ingress and egress particularly easy. Another unique feature of the Model X is the panoramic glass roof. The windshield stretches back, curving above the driver's head before finally meeting the tops of the rear doors. There is no break in the glass before that point, meaning one piece of glass acts as both a windscreen and a moonroof.
Other standard equipment on the Model X includes a class-3 tow package, a 17-speaker premium sound system, an auto-leveling suspension system and power-adjustable heated front seats. A heated leather steering wheel, proximity keyless entry and three-zone climate control are also included.
The interior seating can be upgraded to hold up to 7 occupants.
Tesla's most famous option is probably "Enhanced Autopilot." When equipped, the Model X will keep pace with the other cars on the road, speeding up and slowing down with them, but it will also keep to its lane, even around gentle corners. The system also includes a 360-degree camera and can under certain circumstances, park itself.
