I was comparing against the current Benz V8. The new TT isn't out on the streets yet so who knows what number it'll put out.

^ This.

In fact, the current Lexus 4.6 is rated the same as MB's current 5.5, but the MB engine makes the Lexus engine feel like a V6 in comparison.

Lexus needs to wake up soon, and either increase the displacement or implement a small turbine to boost the power output of their V8 engine.

You would expect a lot less torque from a normally aspirated engine though, no? Why jump from the topic of HP to FT/Lbs?

Traditionally, Lexus' cars have weighed less than Mercedes cars, in fact, less than most cars in their respective classes, negating the need for a large displacement torque monster.

Personally, I'd rather Lexus try and keep the ballooning curb weights in check rather than build a huge displacement toque monster of an engine.

Because the maximum HP output is pretty meaningless. You need to look at torque curve to assess an engine potential.

Well I don't have much experience with the 5.5 to confirm or deny its fuel mileage, but to me, for a car with such engine, fuel mileage is almost irrelevant.

Och, I respect your opinion, but you are hopscotching all over the place on this one. I guess we'll agree to disagree.
