Future of 15m

There are many places where I have flown cross-country where landing out in a 15m ship is a much easier proposition than anything 18m or larger. Many desert or farm strips are designed for crop-dusters or Cessnas. Here in the desert Southwest, conditions are also strong most of the time so that there are few benefits of longer wings.

If you want longer wings, better get a (reliable) engine!

Yes, reliable engines: that would be nice. Unfortunately no
motor gliders have Honda engines; second best might be a
Stemme with a proper 4 stroke?
However the Stemme (S10) is something of a heavy weight
with handling to match: enjoyable yes, capable yes, but if you
could choose to fly a modern 15m or the Stemme you'd choose
the 15m if handling pleasure mattered to you.
I hope the 15m class has a future; I think it's one problem is
wing loading when an engine is on board - hence all the
18m/20m/21m/25m stuff with engines. So you just need to be
a purist and fly "proper" gliders, I used to do this and it is
great up until the moment you have to put your sparkly new
$100K+ carbon fibre ship into an unknown field or some dirt
strip in the middle of a desert. Then you can suddenly
understand why most of those new German ships are bought
with engines.....

As any owner will tell you: there is no such thing as a reliable
motor glider, absolutely all their engines can be guaranteed to
work sometimes, often when you actually need them
