Porsche's new twin-turbo V-8 to be shared across VW Group

Replacing the old 4.8-liter engine, this new 4.0-liter unit packs new features and better efficiency.

I just want to hear it.

Have you heard of the International Vienna Motor Symposium? It's basically a conference that looks at the latest powertrain innovations, from electric to good ol' gas. At the 37th symposium, which took place in April, Porsche unveiled a new 4.0-liter, twin-turbocharged V-8 that will eventually be shared across the Volkswagen Group.

Replacing the outgoing 4.8-liter V-8, which currently sees duty in the Cayenne and Panamera, this new eight-cylinder features a smaller, 4.0-liter displacement. It's tenuously connected to the 3.0-liter V-6 seen in Audi and Porsche products, as more automakers move to 0.5-liter individual cylinder displacement.

This specific engine will first arrive in the next-generation Panamera, and in one of its most powerful guises, will put out 550 horsepower and 568 pound-feet of torque. Cylinder deactivation will allow it to run on just four cylinders for a major efficiency boost. Car and Driver also noted that it's ready for both stop-start technology and hybrid applications.

The 4.0-liter unit will eventually stretch its wings and fly into other VW Group vehicles, most of which will be on the larger side, like the Porsche Cayenne, the Audi A8 (or S8), and Lamborghini's forthcoming Urus SUV.

In the meantime, I'm going to spend most of my waking hours trying to figure out how to install this into my Golf SportWagen, or perhaps that local 914 for sale that I've had my eye on. That would be one hell of an engine swap, wouldn't it?
