From Tesla’s website:
Model X is a family vehicle with performance roots. The Tesla Vehicle Platform enables Model X to perform in ways never expected from a car of its size. With a center of gravity lower than any other SUV, you’ll notice nimble reflexes at every turn. The electric powertrain delivers instant torque for confident lane changes, even when loaded with seven adults and all their gear.
Model X is offered with optional Dual Motor All-Wheel Drive. The second motor enables more than all-weather, all-road capabilities: it increases torque by 50%. When outfitted with AWD, Model X Performance accelerates from 0 to 60 mph in less than 5 seconds, outperforming the fastest SUVs and many sports cars.

Model X is the safest, fastest and most capable sport utility vehicle in history. With all-wheel drive and a 90 kWh battery providing 257 miles of range, Model X has ample seating for seven adults and all of their gear. And it’s ludicrously fast, accelerating from zero to 60 miles per hour in as quick as 3.2 seconds.
