In a letter written to the shareholders of electric carmaker Tesla Motors on Thursday, the company's billionaire founder Elon Musk said that Tesla's yearly production of cars will likely touch more than 100,000 by the end of 2015.

Predicting an annualized car delivery rate of over 100,000 by Tesla by next year, Musk said that the company's existing Model S sedan will apparently account for nearly half of those cars; while the other half will comprise the Model X, which will start shipping early next year.

The projections made by Musk imply that Tesla is not just planning to deliver 100,000 units of Models S and Model X vehicles in 2015, but, by the end of the year, it will begin delivering vehicles at a 100,000-a-year clip.

With the 100,000 car delivery figure projected by Musk underscoring a bullish prediction which is bound to delight the investors, the forecast means that Tesla does not see any let up in the demand for the Model S, and is also hopeful of strong pre-orders for the Model X.

Asserting that demand for Tesla's vehicles is not an issue, especially since enthusiasm continues to grow in China. Musk said in the letter to investors that "average global delivery wait times increased because our production growth was unable to keep pace with increased demand."
