The encore to the amazingly well-received Model S will come replete with “falcon-wing” doors and even more family friendly design, and is due late in 2014.

In March this year Tesla pushed back the Model X’s projected production date from what would have been right about now for early 2014 deliveries. Its reason? Tesla said it needed to focus on the global Model S launch now still underway, and just taking root in Europe, Asia, and including China.

On ths latter score, Tesla is trying to overcome a trademark issue over the “Tesla” name, so it’s calling it Tuosule for now.

Back in the U.S., Tesla’s Web site says “estimated delivery in 2015 for new reservations” for the car to start a bit higher than the $71,000-and-up Model S. The implication is Tesla has a long list of intenders who’ve plunked down either $5,000 or $40,000 reservations and should be getting their electric SUVs at the end of 2014 with production ramping up into 2015.

Based on the same “skateboard chassis” design used by the Model S, the Model X ought to be one sleek and quick SUV – blended with the “benefits of a minivan.”

Battery sizes for the Model X are the same as Model S – 60 and 85 kwh – and the vehicle promises 0-60 times of under 5 seconds for the most powerful versions.

“The Model X is critical in Tesla’s development by expanding its range to the popular utility segment – and it will therefore bring in new customers – while providing additional revenue to Tesla,” said automotive analyst, Alan Baum. “This will enable the development of the entry level Model E and provide growth as the demand for the Model S matures slightly.”

Going a step beyond the Model S, the Model X will utilize dual-motor all-wheel-drive, a sure improvement for snow-belt drivers. Originally AWD was to be optional, but in November Tesla said all models will be so equipped.
