So the Mi-26T2V is going to start production in 2021. It replaces the Ukrainian D-136 engines with Russian PD-12V
engines. The PD-12V can do 14,500 hp vs 11,400 hp and is 18% more fuel efficient. So it will have
a substantially greater range.

The claim that it will be limited to the same power as the D-136 is not clearly justified since the upgraded Mi-26
is supposed to function better at higher altitudes and in warmer climates. But it will likely be limited to
some extent since the rotor and drive train cannot be changed arbitrarily.

I wonder if all the drivel about how the Mi-26 was a gas guzzler compared to the obsolete Chinook will
be dredged up again...

well it will exactly mean that: better fuel consumption and it will be able to operate at higher altitudes with full load (and also increase the partial load capabilities at even higher altitudes).
