Does Avalon make 280or268hp/260or248tq?

[dizzle1]

Is the engine still capable of 280hp and 260tq in stock form on every Avalon. I think this is because of new SAE testing that require's 87 octane and AC on which lower's it's output. But thats what wikipedia says I need some professional answer's like from a certified person but if not your comments will help.
