Tesla Model X

The Tesla Model X is a mid-size all-electric luxury crossover manufactured and marketed by Tesla, Inc. The vehicle is noteworthy because it uses falcon-wing doors for passenger access.

The Model X was developed from the full-sized sedan platform of the Tesla Model S. The Model X has an EPA size class as an SUV, and shares 30% of its design with the Model S, 1/2 of the originally planned 60%, and weighs about 10% more. Both the Model X and Model S are being manufactured at the Tesla Factory in Fremont, California. 

On September 29, 2015 a series production vehicle was shown. It has a panoramic windshield. According to Tesla CEO Elon Musk, it is the safest SUV in terms of frontal and side impact collision, being more than twice as safe as the next closest SUV in rollover tests as well. The Model X featured Autopilot as standard, and has an optional full self-driving system. The Model X has standard a crash avoidance system that uses radar-based autonomous emergency braking (AEB) and side-directed ultrasound detection that steers the car away from hazards. Tesla uses a wide-band radar system to help avert the falcon wing doors from hitting nearby objects when opening or closing.

The Model X weighs about 8% more than the Model S and shares about 30% of its design – down from around 60% expected when development began. The cargo space is 87.8 ft³.

The Model X has been available with 4 lithium-ion battery packs over the years, rated at either 60, 75, 90, or 100 kW·h. The highest performance version, the Model X Performance, accelerate from 0 to 60 mph in 2.6 seconds and the 1⁄4 mile in 11.4 seconds, surpass the fastest SUVs and most sports cars. The Model X's all-wheel-drive system uses 2 motors, unlike conventional AWD systems that have a single source of power.

The company planned to offer rear-wheel-drive models, but rather all models use 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 5000 lb or 2250 kg.
