Tesla has been ramping up production of the Model S and Model X, hitting over 50,000 deliveries of the $100,000 plus vehicles in 2015 -- with over 17,000 of those in the final quarter of the year.
In Tesla terms, a delivery is only counted when the car is transferred to the end owner with all the paperwork correct. Because of this these figures may not be 100 per cent correct -- more like just over 99 per cent.
In Q4 Model S deliveries were up 48 per cent on the previous quarter, and up 75 per cent on Q4 of the previous year, with 17,192 vehicles produced.
Q4 saw production of the new Model X grow steadily, with almost half in Q4 (238 of 507) produced in the final week of the year. 208 of Q4's Model X's have been delivered already, with the rest expected in early Q1.
A spokesperson for Tesla says "Model X deliveries are in line with the very early stages of our Model X production ramp as we prioritise quality above all else."
With over a billion miles driven already, Tesla's foothold in the car market only continues to grow and improve.
