Tesla Motors Inc (NASDAQ:TSLA) has again been tempering with its product offerings quietly. A report from Teslarati claims Tesla has silently removed the base version of its new electric crossover SUV, the Model X 70 kWh from its website, which leaves only two variants of the Model X up for grabs: the starter 90D and the P90D.

The ‘D’ refers to the dual motor setup which trumps the traditional rear-wheel drive functionality and is aimed at enhancing power. The ‘P’ in the most upscale version refers to enhanced ‘Performance’ of the vehicle.

According to data from Modelxtracker.com, quoted by Teslarati, the company’s overwhelming order flow has mostly favored the upscale versions, with nearly 93% orders for either the 90D or the P90D. While there have been some orders for the 70 kWh version, the website notes that none have actually been delivered. That implies Tesla may have already been planning to ditch the base 70 kWh version to focus mainly on the high-potential upscale versions.

Back in September 2015, when Tesla’s CEO Elon Musk, initiated deliveries of the Model X, he said the base version would likely pack a 70 kWh battery pack. Some media reports are now speculating that the increased interest in more premium versions of the electric crossover could trigger the company to produce perhaps a 100 kWh Model X too.

Notably, this is not the first time the company has been tinkering with its base models. When Tesla first began selling the Model S sedan in mid-2012, the line-up also included the 40 kWh version of the premium sedan that was later stripped off on the back of sagging demand, leaving the higher 60 kWh variant as the base one for the Model S. However, last year, Tesla again upgraded the base version of the Model S to 70 kWh citing increasing number of customers preferring Tesla cars with larger battery packs that promise a larger range.

By focusing on the hottest selling variants for the Model X and S, Tesla is hoping it can maintain its strong sales momentum that has been at the heart of the stock’s speeding rally over the past couple of years.
