Tesla Model S sales are booming and the company is quite proud of this.

The company announced yesterday from Detroit that sales in the fourth quarter of 2013 were the highest in company history by a significant margin, with almost 6,900 vehicles sold and delivered. Through this result, Tesla exceeded prior estimates by approximately 20 percent.

Tesla explained a higher than expected number of cars was manufactured as a result of an excellent effort by the Tesla production team and key suppliers, particularly Panasonic.

The two key drivers of demand were the superlative safety record of the Model S and great performance under extremely cold conditions, continued Tesla.

Tesla proudly states in the release it remains the only manufacturer with a perfect safety record of zero deaths or serious, permanent injuries ever. Including the Roadster, Tesla vehicles have now been on the road for almost six years in 31 countries with almost 200 million miles driven to date. Despite dozens of high speed collisions, the driver and passengers have always been protected. Tesla said this is its proudest achievement.

Cold Weather Performance

Cold weather performance is another aspect of the car Tesla is very proud of, explaining that due to the precision of its electric powertrain, the Model S has outstanding traction control relative to the much higher latency and inertia of a gasoline powertrain. As a result, Tesla states its Model S is able to perform better on snow and ice than many all-wheel drive gasoline cars.
