Porsche Unveils New Twin-Turbo V-8
After debuting in the Panamera this new engine will likely spread across the VW Group
Porsche is taking the lead on the development of the Volkswagen Group’s V-8 engines—and that’s why it presented the “newly developed V-8 turbo engine from Porsche” at the 37th International Vienna Motor Symposium. While the new V-8 will launch in the new Panamera Turbo, it’s not solely a Porsche engine. It’s loosely related to Audi’s new, turbocharged 3.0-liter V-6—launched in the new S4 and Panamera bound as well—and it will migrate to a number of the VW Group’s upmarket models.
Its appearance spells the end of the 4.8-liter V-8 engines currently offered in the Panamera and the Cayenne, but fret not. We’ve had some experience with this new engine, and we can attest that it delivers everything expected of a true Porsche engine, especially high-end performance. Force-fed by two twin-scroll turbochargers, it’s rated at 550 horsepower which is available at 5750 rpm, and 568 lb-ft of torque from 1960 to 4500 rpm—redline is 6800 rpm. That puts it virtually on the level of the previous Panamera Turbo S with its 4.8-liter turbo.
The new engine also consumes a lot less fuel than its predecessor, thanks in large part to the cylinder-deactivation system. What the engineers call “half-engine mode” is activated at low loads between 950 and 3500 rpm, and it can cut fuel consumption by up to 30 percent. The engine also is optimized for start-stop systems and, Porsche points out, for hybrid applications. So, we eventually might get turbocharged V-8 engines with additional electric boost? That’s kind of exciting.
The new engine theoretically can be built alongside Audi’s new, turbocharged 3.0-liter V-6—and both of them are designed to fit longitudinal architectures like the Audi-developed MLB platform or the Porsche-developed MSB platform. On the former, it will be mated to a ZF-sourced eight-speed automatic with a torque converter; on the latter, it will be coupled with a ZF eight-speed dual-clutch automatic.
Look for the new, Porsche-designed V-8 to appear in a wide range of vehicles, including the Porsche Panamera and Cayenne, uplevel Audis, the Lamborghini Urus, and a number of Bentley models.

If it's really based off the same modular engine as the 3L V6, well VWAG already has a 4L V8 twin turbo used by Audi and Bentley - so did Porsche really come up with an all new 4L V8? Or is this all just old hash.

I'm amused that C+D claim they have "experience with the new engine" but can't even tell us the literage.

It was a tongue-in-cheek comment about C+D claiming they already have sufficient "experience" with the engine to make subjective claims about its performance. There is no embargo, as other news sources have already reported the literage.

Indeed. So, again, my question: Is this really a new engine?
