Well it looks like they are getting some stronger power figures for the 2019 available wrangler JL that was announced.
The 3.0-liter EcoDiesel V6 engine, which will be available starting in 2019, makes 262 horsepower and 442 lb-ft of torque. 8 Speed Auto transmission only.
Quite a bump. From...

Glad to see FCA is continuing the use of the EcoDiesel! This tells us it's probably here to stay.
