Pricing, photos and specifications from the online configurator of the production Tesla Model X people mover and crossover mashup have begun hitting the internet.

Photos seen in this article were initially published by either Tesla Motors Club, EV Obssession or Flickr user tobi_wan_kenobi.

The configurator is only currently available to prospective buyers who are part of the Signature pre-ordering scheme, which requires Model X purchasers to stump up US$40,000 ($56,000) in advance.

Screencaps confirm that the new Model X Signature Series will have a base price of US$132,000 ($185,000) before taxes and fees, and not inclusive of federal and state tax credits.

In Signature Series trim the Model X is fitted with a 90kWh battery pack, and the all-wheel drive system features a 193kW motor for the front wheels and a 375kW motor for the rear axle.

Working together, Tesla says that the electric motors are able to propel the Model X Signature from 0-60mph (0-97km/h) in 3.8 seconds and onwards to a top speed of 250km/h. The official range estimate from the USA's Environmental Protection Agency is 386km.

A Ludicrous Speed upgrade package, priced at US$10,000 ($14,000), will allow for a 0-60mph time of 3.2 seconds and a quarter mile (400m) time of 11.7 seconds.

While the production version of the Model X features proper wing mirrors, altered tail-lights, and slightly revised side window shapes, it still features the "falcon wing" rear doors of the 2012 concept car.

Standard features across the Model X range include an automatically retracting rear spoiler, satellite navigation, heated and electronically folding wing mirrors, keyless entry, parking sensors, blind spot monitoring, and automated emergency braking.

Signature buyers also receive automated parking, air suspension with GPS memory, a top-spec audio system with satellite radio, automatic lane steering, power operated tailgate, high-grade interior trim fittings, heated and cooled leather seats, independently operable three-seat second row, and fold flat two-seat third-row.

Options for the Model X Signature extend to a towing package and a sub-zero weather package, which includes a heated steering wheel, heated second- and third-row seats, washer nozzle heaters and wiper defrosters.

As with the Model S, Model X drivers also have free access to the company's network Supercharger stations. The first customer deliveries in the US of the Model X are expected to begin later this year.
