Cessna will offer the 172S Skyhawk with a Thielert turbo diesel engine

I'd rather say that Cessna is anticipating the difficulty to explain why
they still sell engines with 50 year old technology, once the pilots
start to recognize that there are modern engines around which burn less
than half the fuel.

I like the idea that there is more energy per pound in Jet A fuel than
AvGas, but I have no idea of the failure modes nor expected TBO and
other performance, operational, and maintenance issues. What should a
pilot expect to find has changed in the Thielert engine equipped C-172
other than higher power available at altitude, increased range, and
fewer refueling options?
