No replacement for displacement....oh...wait...
Mercedes AMG has just upped the ante, replacing their 2.0T 382 hp engine with a 416 hp version. That's just 10 under what the Gen 5 Camaro SS was rated. So, roughly 4.2L of displacement was replaced.

Jesus that's insanely power dense.

I'd like to hear it. There is still no replacement in that respect.

That's impressive for an OEM engine. Even more impressive if it is actually a long term reliable engine.
The torque is even pretty decent at 370 with most of it coming on at 2,000 rpm as the article states. That's probably still a good 40+ tq under what an American SOHC V8 making 416 HP would do in torque as typically the tq ends up even or higher than HP. DOHC, such as the Coyote...then sure, its about the same hp to tq ratio. No replacement for displacement argument is kind of silly now days. I mean in one hand...sure there is a replacement, and it's called forced induction. Want 300 or 400 HP or more without a V8? Easy. Then again, some would say its not a fair comparison. Put a turbo on a V8 and then see what kind of power you get. But if good ole V8 music is your thing...yeah there is no replacement.

There is no replacement for displacement. Anything done to that 4 banger could be done to a bigger engine and make even more power.

For a few bolt-ons you can take that boring ol' v8 up 100HP. For a little bit of boost you can easily double the output. And there would STILL be more up on the table.

This must have GM really scratching their heads. Cadillac's newest offering is a twin-turbo V-6 with an amazing 300 or so hp. The technology used to underpower the displacement of a V-6, add twin turbos and produce a measly 300+ hp must be a GM exclusive trade secret that evades Mercedes.

30 pounds of boost is a lotta boost. Wonder how long it'll last on the street

Don't know why they didn't just keep that one. Also, isn't the new Caddy doing a turbo 2.7L 4-cyl?

These concepts aren't often noted for their exceptional reliability and ease of manufacture/servicing. They often have complex structures that do not lend themselves well to more practical considerations. It's impressive for sure. Glad to see them pushing the frontiers. Ultimately electric assist will take over soon and provide all the "super/turbo"-charging that one needs.

Impressive for sure.
If the motor is in a lot of boost all the time, say like if any of us drove it, then the point of having a 2 liter motor (fuel efficiency) has gotta be nearly lost completely. some engineer tell me i'm wrong.

Yeah, like the EcoBoost. Can't have both the Eco and the Boost.

Well, technically you're simply using boost, on said hypothetical V8, to replace displacement of an even larger engine. Boost is literally allowing the processing of air and fuel that would not be present via atmo alone. Making a 2.0L process the air/fuel of a 4.0L is no different than making a 4.0L process the air/fuel atmo would provide to a 8.0L engine. So, the statement that "Yeah, well, I can boost the bigger engine and make even more power." In fact further verifies that boost is a functional replacement for added displacement.
