Last summer, we reported about the possibility of a Porsche IPO valued between $55 billion and $110 billion. So far, that hasn't happened. What was interesting about that estimate was that it could exceed the total value of Porsche's parent company, the Volkswagen Group, then valued at about $97 billion. Spinning off Porsche has the potential to generate a significant amount of cash at a time when VW could really use it towards its massive electric vehicle plans. Then again, retaining Porsche also has its benefits, among them being the fact it's a guaranteed and consistent money maker. So, what will VW Group ultimately decide?

According to Bloomberg, VW Group CEO Herbert Diess has confirmed there are no current plans to list Porsche.

"We think we are well organized now in the premium sector, this is working for us quite well now," he said. "We don't sell any of the other assets currently."

Over the next five years, VW plans to spend over $84 billion in various new technologies, including self-driving cars and major software advancements. VW has done the math and seems to have ultimately determined it doesn't need to list Porsche to get the money it needs. Chief Financial Officer Arno Antlitz says he's "quite confident" the carmaker's current investments are good enough to generate sufficient cash flow. However, significant cost-savings targets still need to be met.

Porsche has clearly helped pave the way forward for the Group's EV plans thanks to significant demand for the Taycan, its first-ever battery-electric model. It continues to outsell the legendary 911. An all-electric Macan is due next year, which will likely be followed by an electrified Cayenne. The next-generation 718 Boxster and Cayman was recently confirmed to be ditching internal combustion as well.

There has been some concern that Porsche and Audi could find themselves competing with one another but VW executives say that won't happen. Porsche will continue to be the performance brand while Audi will be the Group's technology leader.
