Tesla Motors Inc (NASDAQ:TSLA) could unveil its Model S extended wheelbase version towards the end of this year, according to a report from GAS2 citing an insider. The new version of Model S will be a good fit for United States and European customers as well as in China, where consumers are ready to spend more for longer rear leg room.

China in focus again

Tesla Motors Inc (NASDAQ:TSLA) is considering the Chinese consumers, also as most opt to sit in the rear seats rather than driving themselves. The obvious reason behind owners opting to sit in the rear is week-long traffic jams in China. Luxury automobile brands like Mercedes and BMW already offer long-wheelbase models to Chinese customers and Tesla plans to follow the same strategy. These extended versions will enable Model S to gain more traction in China without too much additional cost.

Even though Tesla Motors Inc (NASDAQ:TSLA) is releasing an extended wheelbase Model S, keeping in mind the specific needs of Chinese customers, the demand is already high.

Although relatively rarely, some customers have complained about the limited leg room in the back seat. Recently, CEO Elon Musk vowed to fans that Model S would be provided with a set of new features giving owners a fresher feel, and different versions of the Model S such as a coupe and a convertible are already in great demand.

Doubts over release date

An insider has supposedly reported that Tesla Motors Inc (NASDAQ:TSLA) Model S extended version will be available before the Model X production version. However, the company has had to utilize a lot resources and talent to design the Model X, which has been delayed due to the unique falcon wing doors that are difficult to design. As of now, the company is focusing on the Model X, suggesting that the Model S extended version will not be seen until later.

Though there might still be doubt over the extended wheelbase version of Model S, Tesla Motors Inc (NASDAQ:TSLA) has already launched a right-hand Model S in the United Kingdom. The company expects that a right-hand version will drive the growth in the region. The electronic vehicle manufacturer is eying strong expansion in the region, even though it has set up just one store and one service center in London to date. The car-maker is aiming to set up stores and service centera throughout the country by the end of 2014.
