Sony and Honda recently announced plans to build electric vehicles together, with Honda taking care of manufacturing while Sony provides mobility service.

Now, it appears the companies plan to separate the EV operations. Kenichiro Yoshida, Sony's president, and CEO told Nikkei that it is better to separate the joint venture from Sony or Honda in the long run. 

'I hope that I'll be able to speak a little about it at some point in the near future,' Yoshida said. While he didn't elaborate, Yoshida did say there's a 'possibility' that the companies may sell a stake in the joint venture or have an initial public offering. 

It was announced in March that Sony and Panasonic would form a joint venture. In its statement, Sony said they would 'fill the world with emotion through creativity and technology,' likely through high-tech interiors and fancy entertainment systems. According to the company, it wants to create a mobility system 'based on safety, entertainment, and adaptability.'

The Honda company announced last year that it would transition its entire lineup to electric vehicles and fuel cell vehicles by 2040. As part of that, it will spend $40 billion on electric vehicles and launch 30 new models by 2030.

The Sony tie-up is unclear how it fits into Honda's plans, but its only true electric vehicle sold in the west is the niche Honda E sold only in Europe.

It is believed that other tech firms such as Apple will soon join the fray, and that electric vehicles will become more connected much like Sony's Aibo robot dog or gaming consoles. Providing network functions as the basis for mobility will help to evolve mobility, he said.
