Reports indicate that Porsche is developing a new flagship hypercar, internally codenamed ‘S1’, to succeed the 918 Spyder. The vehicle is expected to be an independent development rather than a derivative of the 911 series, potentially utilizing a proprietary platform. 

A significant technical feature rumored for the S1 is an eight-cylinder boxer engine, a configuration the company has prototyped but never used in a production road car. With an estimated starting price of approximately 500,000 euros, the model is positioned to target higher profit margins within the ultra-high-end segment.
