If GM can't squeeze 320 from a 4-cylinder then their engineering team needs a slap in the face. They already have a 300hp inline 4, so an extra 20hp isn't asking for much.

I'm pretty sure the engine you are referring to are big dollar engines. GM can certainly do that but the cost would get more and more prohibitive..
Now bump it to 2.3 or 2.5 and you can get 300 to 320. But for 100,000 mile durability a 300 plus 2.0 liter would need some pretty high priced internals. And I wouldn't want the money into the 4 cylinder.
