Unlike other automakers, Tesla doesn't release monthly sales figures. Instead, we learn about sales through quarterly conference calls with investors. In the most recent one, Tesla said that it delivered about 2,400 of its luxury EV sedans between October and December, edging out the 2,371 C-Max Energi plug-in hybrids sold by Ford. The Chevrolet Volt extended-range plug-in was by far the best-selling plug-in during the quarter, moving 7,113 units. Toyota sold 5,016 of its Prius Plug-in hybrids during the quarter, while 4,607 Nissan Leaf electric vehicles were purchased.

Tesla is looking to boost sales further and has said it has reached its production capacity of 400 vehicles a week. CEO Elon Musk said he's not interested in going to 500 vehicles a week, which would be possible, before the company further reduces its costs to build each vehicle.
