I'm a pretty big Honda fan, but I fear they're in a bit of a pinch. They are on record that they don't like forced induction (turbo or supercharger). They cite drivability, environmental and efficiency (superchargers) issues. IMO, the driveability issues can be solved, as someone pointed out, Honda is an engine company.
The biggest stumbling block to turbochargers is that in order to tame lag (drivability) the turbo(s) need to be close to the exhaust manifold. Unfortunately, the heavy cast iron turbos soak up all the heat needed to fire up the catalytic converters when performing a cold start. Cold starts are when emissions are the highest.
What can they do? Personally I'd like to see a belt driven supercharger with an electromagnetic (a/c style) clutch to disengage it during low load operation. Or, could IMA generate enough electricity to power an electric supercharger? The current IMA motors make around 13 hp, I recall reading that smaller superchargers "waste" around that much due to parasitic drag.
Just a thought?

Well, it may go with out saying that the TSX will get some sort of up grade. How is the question. I always figured a slight increase to around 210 for his generation as we'll have to wait until the next Accord for CR-V i4 to see what the possible engine will be.
Honda being the wizzards they are may have a trick up its sleeve to play. Look at the trunk in the Ridgeline! Who would have thought about a pick'em up truck having a trunk? Honda may have an answer to your comments Colin.
