Tesla Motors appears poised to define the automobile of the future, making it the "most important car company in the world," analyst Adam Jonas said Friday.

The comment comes a day after the electric carmaker reported quarterly earnings and revenue that beat Wall Street estimates.

"The reason why we say they're the most important car company in the world is because if you haven't noticed, the entire automobile is being reinvented by technology," Jonas, who heads Morgan Stanley's global auto research team, said on CNBC's "Halftime Report."

"And the role of software, we think is going from around 10 percent to 50 or 60 percent of the value of the vehicle when we're kind of reaching full autonomy by [the] middle or latter part of [the] next decade, and Tesla's really uniquely positioned. So, it's not just EVs but also battery storage, stationary storage and cars that think for themselves and make decisions, artificial intelligence, machine learning. It's on a completely different level than any other car company."

Tesla also announced this week that it would fund 40 to 50 percent of the cost of its planned $5 billion battery "gigafactory" and that it planned to build more than 60,000 vehicles in 2015.

The automaker's stock could experience some "awful bumps" as it develops its expansion plans, Jonas said. "These things don't move in a straight line."

Jonas holds an "overweight" rating on the stock and a price target of $320 per share.

"This is a very ambitious company. It probably, in a perfect world, should not be publicly traded," he said. "We should not be privy to the, let's say, growth and formation of the company at this early stage."
