A lot of the extra consumption comes from sealing issues higher combustion temps and emissions kept General Motors from development of that motor. Whankel design sold to Mazda and they developed it. Never a very long lasting engine but smoothness and high revolutions per minute allow that small engine size do lots of work.

Yes it is. The rotary engine also has exhaust tempretures higher than that of its combustion engine brother.
However, power and acceleration are very good, a mazda rx 8 sports car only has a 1.3 litre rotary engine, yet can do 0-60 pph in about 6 sec!

We can't eactly compare both these engines this way. In term of power output, a 1.3 litre rotary engine can produce the same power as a 2 litre engine easily. The fuel consumption between the two engines are about the same

They typically consume more fuel than a piston engine because the thermodynamic efficiency of the engine is reduced by the long combustion-chamber shape and low compression ratio.

Yes, and they use a LOT more motor oil.
