H4 (I just like the 2.0L Subaru more, but there is nothing wrong with a STI at all):

I6 Diesel (It makes its V8 counterparts look bad on a daily basis, it's the best diesel on the market, IMO, even though I don't like what these engines come in):

I6 Gas (I wasn't going to post a gas contribution for the six cylinder section, but this picture hadn't come up yet):

V8 (I choose the 289 because it was Shelby's engine of choice, you get a model though):
