Core Event: Planned S1 Supercar Details
Porsche is reportedly developing a new flagship model internally called the S1. German business newspaper Handelsblatt says the car will be powered by a flat-eight gasoline engine and priced at around $600,000. Motor1 cites the same source for a price of €500,000 (about $574,000 at current exchange rates). The model is expected to be previewed to investors on October 7, when Porsche holds its scheduled Capital Markets Day. Porsche has not issued an official confirmation, so the name, specifications and price remain unverified rumors.
Background & Context
Porsche’s flat-eight heritage dates to the early 1960s, when an H8 Formula 1 car and the later 908 sport-scar used boxer-eight engines. After the 918 Spyder ended production in June 2015, the company’s only subsequent supercar concept, the 919 Street, never progressed beyond a clay model. The S1 would therefore be the first road-going Porsche with a flat-eight powerplant, marking a departure from the brand’s recent focus on hybrid and electric technologies.
Data & Statistics
- Engine: twin-turbocharged 5.0-liter flat-eight, delivering roughly 750 hp and 738 lb-ft (1,000 Nm) of torque, with a redline of 9,000 rpm and a manual gearbox.
- Price: reported at €500,000 (~$574,000) by Motor1 and about $600,000 by Handelsblatt, roughly twice the price of the current 911 Turbo S and well above the domestic price of a 911 GT3 RS.
- Market positioning: described as a standalone hypercar rather than another 911 variant, intended to sit above the existing 911 range.
Official Statements & Responses
Porsche has not formally announced the S1, and the company advises that all details remain speculative.
Why It Matters
If realized, the S1 would signal a rare commitment to a high-performance gasoline engine at a time when many manufacturers are accelerating electrification. The projected price and limited production volume align with Porsche’s stated goal of sustaining earnings through premium, low-volume models. The S1 could also set the stage for other upcoming projects, such as a new gas-powered Macan replacement, a three-row SUV above the Cayenne, and the anticipated 911 GT2 RS slated for 2027.
