Porsche retains 4.0‑liter V8 amid changes to meet emission rules

Fans of Porsche worried about a potential engine cylinder increase can breathe easily—the German automaker has no plans to forsake its 4.0-liter V8 engine. The engine won’t emerge in the next few years without changing.

The evolving emission standards have reshaped the automotive scene across Europe. This shift forced companies to overhaul their engine selections, making some models discontinued or no longer offered in Europe. The anxiety around the Euro 7 standards intensified these concerns, with many speculating about which engines would be phased out following the new regulations.

However, the compromise reached between manufacturers and the European Union won't drastically alter the existing standards for passenger vehicles. This news has reignited hope among many enthusiasts to continue using their beloved and familiar engines.

Porsche's commitment was confirmed during the Formula 1 Australian Grand Prix. The local portal Carsales conducted a discussion with Thomas Freimuth, head of the Porsche Panamera model line, which revealed that the twin-turbocharged 4.0 V8 engine would remain in Porsche's lineup even after the new standards take effect in 2030.

Yet, maintaining the status quo doesn't mean the engine will transition to future Porsche models without modifications. Freimuth highlighted another factor influencing the driving experience of cars like the Panamera: stricter noise regulations, which tighten annually and necessitate adjustments to the entire engine system.
