Tesla Model X

The Tesla Model X is a full-sized all-electric crossover SUV made by Tesla Motors that uses falcon wing doors for access to the second and third row seats. The prototype was unveiled at Tesla’s design studios in Los Angeles on February 9, 2012. The Model X has an official EPA rated 250–257 mi (402–414 km) range,  and the combined fuel economy equivalent and energy consumption for the AWD P90D was rated at 89 mpg-e (23 kWh/100 km or 39 kWh/100 mi). The Model X was developed from the full-sized sedan platform of the Tesla Model S; both are being produced at the Tesla Factory in Fremont, California. First deliveries of the Model X began in September 2015. Since its introduction, about 2,700 units have been delivered by early April 2016.

HHistory
Initially Tesla planned for deliveries to commence in early 2014. However, in February 2013, the company announced that deliveries had been rescheduled to begin by late 2014 in order to achieve its production target of 20,000 Model S cars in 2013. In November 2013, Tesla said it expected to begin Model X high volume production the second quarter of 2015. In November 2014, Tesla again delayed and announced that Model X deliveries would begin in the third quarter of 2015. Deliveries began on September 29, 2015. Among the reasons for delay were problems with the falcon-wing doors and cooling the motors when hauling trailers.

In 2016, the company filed a lawsuit against Hoerbiger for not producing satisfactory falcon-wing doors for the Model X. Tesla claimed the doors suffered from oil leakage and overheating. Many believe this is one of the reasons for the delay of the Model X.

On July 29, 2015, Tesla announced a referral program though October 31, 2015 wherein owners of a Model S who refer 10 new buyers gain the option to buy a Founder Series Model X for the price of a base model. The first person (in each of three regions; Americas, Europe, Asia-Pacific) to reach this 10 referral point would be given this model for free.

Design
A series production vehicle was unveiled on September 29, 2015. It has a panoramic windshield. According to Tesla founder Elon Musk, it is the safest SUV in terms of frontal and side impact crash, being more than twice as safe as the next closest SUV in rollover tests as well. Standard radar-based AEB and ultrasonic-based side collision avoidance system to steer occupants away from a side collision. Tesla developed an ultrasonic sensor that can see through metal to keep falcon wing doors from hitting nearby objects when opening or closing. Musk claims the car features the first true HEPA filter in a car, with medical grade cabin air cleanliness comparable to that of a hospital operating room. When the car operates at maximum capability (enabled with a "Bioweapon Defense Mode" button), Tesla claims that no viruses, bacteria or spores can be detected in the cabin.

The Model X features double hinged falcon wing doors, which open upwards allowing the leading edge of the door to remain tucked close to the body, unlike traditional gull-wing doors. Tesla claims the falcon doors make access easier. The Model X offers room for seven adults and their luggage in three rows of seating and front and rear trunks.

Specifications
The Tesla Model S  and Model X share the same platform and 30% of their parts

The Model X weighs about 8% more than the Model S and shares about 30% of its parts content – down from around 60% expected when development began.

The Model X has a choice of two lithium-ion battery packs, rated at either 75 or 90 kW·h – the same choices available on the Model S – and the highest performance version of the model P90D goes from 0 to 60 mph (0 to 97 km/h) in 3.2 seconds and the 1⁄4 mile (400 meters) in 11.6 seconds, outperforming the fastest SUVs and many sports cars. The Model X's all-wheel drivesystem uses two motors (one for the front and the other for the rear wheels), unlike conventional AWD systems that have a single source of power. The Tesla Model X features an official EPA rated 250–257 mi (402–414 km) (P90D and standard 90D) range, which according to valuewalk.com translates to approximately 310 mi (500 km) range on the European NEDC testing cycle.

The company planned to offer rear-wheel drive models, but instead all models incorporate all wheel drive. The standard AWD has 259 horsepower (193 kilowatts) on both the front and rear motors, while the performance edition has 259 hp (193 kW) front and 503 hp (375 kW) rear. With an optional towbar, the Model X has a towing capacity of up to 5,000 pounds (2,300 kg).

Production and sales
Tesla started taking reservations for the Model X in February 2012 without announcing prices. The standard Model X required a US$5,000 deposit, while the no longer offered Signature model required a US$40,000 deposit as of 2013. More than 20,000 Model Xs had been reserved by September 2014. In August 2015, user groups estimated around 30,000 Model X pre-orders had been received, compared to 12,000 for the Model S.

The first six Founders Series models were delivered at a market launch event in the Fremont factory on 29 September 2015. The first Signature edition was delivered on 18 December 2015. Pricing for the limited edition Signature version of the Model X varies between US$132,000 and US$144,000,  while the standard production version of the Model X will be priced at US$5,000 more than a comparably equipped AWD Model S that is priced at US$75,000 for the base Model 70D.

Tesla delivered just 208 of the Model X to customers in the fourth quarter of 2015, having produced 507. Model X sales totaled 2,400 units during the first quarter of 2016. According to Tesla Motors, deliveries were lower than expected because production was impacted by severe Model X supplier parts shortages in the first two months of 2016. Cumulative sales totaled 2,612 units through March 2016.

After the first quarter of 2016 all Tesla Model X deliveries had gone to US customers. Nevertheless, in January 2016 a Tesla car other than the Model S was registered in Germany and a Tesla Model X was sighted driving there with a license plate from Ingolstadt. Since the Audi headquarters are located in Ingolstadt, this led to speculation that Audi has acquired a Tesla Model X as part of its effort to develop its own battery-electric SUV.

Known issues
On April 11, 2016, Tesla voluntarily recalled 2,700 Model X due to safety concerns. During collision testing, it was found that the third-row seats would unlatch and fold over to the second row. Tesla urged customers to avoid using the third-row seats until it has been repaired.

The falcon-wing doors sometimes do not open or do not latch when closed and occasionally the windows will not open or close all the way.
