CHECK OUT: 2016 Tesla Model X electric SUV first drive by Model S owner Tesla Motors customarily starts production of a new model with the most expensive, most heavily-optioned versions, so Model Xes built thus far have been either the 90D or P90D (performance version) with the larger 90-kwh battery. In due course, buyers who specify the 75D variant will have their vehicles scheduled for production too. Tesla says deliveries should start in June. 2016 Tesla Model X owned by Ron Merkord, March 2016 [photo: David Noland] Meanwhile, the 2016 Model X 70D will join the 2012 Model S 40 in the lineup of Tesla vehicles that never actually made it into production. (The very small number of 40-kwh Model S cars delivered to buyers who had ordered them were actually fitted with the 60-kwh battery pack and a software patch to limit its range to that of a 40-kwh version.)
