When Tesla Motors Inc (NASDAQ:TSLA) will be a “real car company”

Like analysts at Wedbush, those interviewed by NPR say the key to Tesla Motors Inc (NASDAQ:TSLA)’s long term success is going to be consistency and whether the company can grow beyond its current small niche of early adopters. Nonetheless, they also say that the EV automaker has managed to do things that now-dead car makers have tried to do and continues to show that it can overcome the hurdles put in its way.

NPR’s Sonari Glinton reports that analysts believe investors are rewarding Tesla for getting past the point where other EV automakers have gotten. They also note that while shares of Tesla Motors Inc (NASDAQ:TSLA) have topped $150, century-old General Motors Company (NYSE:GM) is at less than $40 while Ford Motor Company (NYSE:F) hovers in the mid-teens.

Can Tesla Motors Inc (NASDAQ:TSLA) remain consistent?

Analysts generally say Tesla Motors Inc (NASDAQ:TSLA) must still prove itself by continuing to grow stronger over the long term. The company must show consistency, not only in the quality of its vehicles but also in the strength of its financial situation.

And finally, they need to see a low cost, high volume electric vehicle that’s a success.
