While Honda is in a bit of a rut, I think they're not too badly off in terms of technology... the R-series engines are pretty good, and the integrated exhaust manifold and EGR were pretty nifty when first introduced. The L-series engines in the first-generation Fit with dual spark made for some pretty impressive economy numbers, though the CVT was a real stinker when it came to maintenance and longevity. The problem is, everyone is catching up and leapfrogging them, while they've basically had the same engines for the past seven to eight years.

I think the difference is in the injection pressures and the benefits derived from the higher pressures you can get out of new injectors.

I recall that Mitsubishi had some of the first modern, electronically controlled direct injection engines in the 90's (contrary to Audi's claims), but they didn't continue with them. Shame. Some of those engines were very good, and included some innovative touches like continuously variable radiator fans (a pain to wire up when you were swapping one of these babies in).
