for compression, if you get pre-detonation then that will ruin your engine, but variable spark and direct injection lets you add in fuel late so you have no risk of knocking. if you run 87 with multi port injection or any other non in cylinder fuel source then sure 11 is really high but a modern engine has the fuel in the ignition chamber so you can run 87 with 11.5 or 12:1, there is also no reason why we still use 87y, the fuel savings in changing to higher compression and more spark advance more than outweigh the 4% increase in cost (4.35 v 4.55 when i got fuel last.)
even with the cars in the US are now the focus (focus euro), taurus (US), fiesta (fiesta euro), ford fusion (mondeo) mustang (US), f-series (US), explorer (US), edge (being replaced by a mondeo), and the escape (c-max). so other than the mustang and taurus there are no US based cars from ford. with the focus they even started with the euro, changed to an US model, the US fails, they back to the euro.
on the buick though, there is no reason that it should make a little more power than my 94 altima (148 WHP, 160BHP rated) and get 2 MPG better. and when i shave the head and get it cleaned and all nice when i rebuild the top this summer i bet i will be at about 215 BHP and pick up that extra 2MPG when i get the fuel injection tuned to lean out a bit.
not really, in the US they have the powerstroke, duratec 1.6/2.0 na or turbo/2.3( 2011 was the last year)/3.5 na or turbo, 3.7 (basically the same as the 3.5), coyote 5.0, and Cceavland 351. they unified alot of power trains over this year and last year.
