New Turbocharged “High Output” Engines Announced

[Gecko]

Toyota, Subaru, and Mazda have announced joint collaboration on a series of new internal combustion engines (ICE) set to launch later this decade.
Here are the details on the new engine announcement from all three automakers:

All three brands are developing EVs in parallel with new ICE-hybrid vehicles
All engines showcased were purpose-built for hybrids and PHEVs, so continuing to build such vehicles will require new investments in ICE technology as well
The companies have been working together on CNFs (i.e. synthetic e-fuels, bio-fuels, hydrogen and methane gaseous fuels) by entering CNF-powered cars into the Super Taikyu series


Toyota announces new 1.5L N/A, 1.5L turbo, and 2.0L turbo four-cylinder engines
The new engines use improved combustion tech and are more compact, allowing more flexible engine mounting and lets Toyota design more aerodynamic cars:

1.5L N/A replaces the 1.5L N/A...

What're the dimensions of an inline 4 like this vs the 5.0L V8?

What're the dimensions of an inline 4 like this vs the 5.0L V8?

Not sure on the exact figures, but I it was noted that the new 2.0T is ~10% smaller and more compact than the existing 2.5L I4, so that's a good bit smaller than the 2UR-GSE. I wonder if it's less than half, or roughly half?

That puts it at about 2100cm3 vs 4969cm3 for the 5L V8. It’s 42% the displacement of the V8. I don’t know if it’s 1:1 obviously the specific dimensions may differ but they could fit a 900+ motor solution into the space of the current V8.

Do we think those power figures are ice plus hybrid assist? I would imagine so.

I wonder if they can double it up to an inline 8 + hybrid (+ turbo?).

If the hybrid drive does 150hp, the motor would be either 250 or 450hp tunes.

Weren’t they talking about a top down, race car platform first, then derive products second approach?
