The engine hasn't been decided, but apparently Cessna is
considering a Diesel engine as an option. A turbo charged
engine will be an option for sure.

The other possibility is one of the new engines from AES (formerly
Bombardier), that allow the use of both 100LL and unleaded fuel.
Although I prefer low-winged aircraft, I'm excited about any advances
that happen. Hopefully this will spur some further development by
other traditional manufacturers.
