know what Diamond changed in the DA40XL to achieve the upgraded
performance numbers? I believe they are claiming a cruise of 158kts on
the XL. I'm assuming this required a 200hp engine, a different prop, or
something significant. The basic plane is pretty clean aerodynamically
so there doesn't seem to be significant potential in cleaning it up to
get it to go faster.


New wingtips (winglets), new 3-bladed scimitar prop, powerflow exhaust.
Same engine.

It will be nice if the powerflow exhaust can be available in existing
DA models,
as a factory installed option. I would like to avoid rerouting the
pipes that my
life will depend on in a 3rd party shop.
