The Model 3 is apparently still stuck in production hell.

Analysts believe Tesla increased production of its Model 3 electric sedan during the fourth quarter of 2017, but the California-based automaker still remains well off its initial production estimates.

After delivering just 220 units of the Model 3 in the third quarter, Tesla had nowhere to go but up during the final period of the year. Although Tesla has not yet revealed how many Model 3s it delivered during the fourth quarter, the average estimate compiled by Bloomberg suggests about 2,917 units of the sedan found new homes.

However, estimates are all over the board. Colin Rusch of Oppenheimer believes the company only delivered 800 units of the Model 3 during the period. Several other estimates have Model 3 deliveries in the 2,250-2,500 range.

Tesla initially estimated it would be able to build 5,000 units of the Model 3 per week by the end of 2017, but "production bottlenecks" prevented the automaker from reaching that goal. Tesla says it should now be cranking out 5,000 Model 3s per week by March. The automaker has also announced a goal of building 10,000 Model 3s per week during 2018, but it remains to be seen if Tesla will be able to hit that target.

The Model 3 is Tesla's first volume model with a starting price around $35,000.
