Incorrect. The engine is the same size and displacement. The automatic transmission on the older models was not reliable enough to support the full engine output. The engine was de-tuned to compensate. Why you'd buy an automatic with this kind of car is another debate.

The engine is the same as the original that came out in 1979. What changed was the ignition timing and the whole injection system. Small internal revisions were made to help the oil slosh around better, which solved a lot of the low oil/blown engine problem. The car is your dependable friend if you baby it, which sports-car lovers never do. So the car is an ideal first sports car for someone who simply never would let an engine get anywhere near orange, much less red line.
Also incorrect. Comparing the RX8's engine to the first-generation RX7 engine is like saying the Chevy LS-series engines are the same as a small block chevy found in a '77 Monte Carlo. The engine was a new design based on Mazda's experience with the earlier iterations of the rotary engine. The intake tract is completely different than past street rotary engines. If you don't take this engine at or near redline, you will miss out on nearly anything that is good about the design.

The car burns oil because it is oil cooled, not water cooled. By all means keep the oil topped off.
Not exactly true. Rotary engines inject oil to lubricate the sealing surfaces of the housings and rotors. The engine is primarily water-cooled. The oil should definitely be kept full and checked regularly (as with any car really).

You have to almost floor a rotary to get going. You get used to driving that way. That problem was only partly solved by having the turbo going all the time. But that also lowers the mileage.
I never kept up with the Mazdaspeed series, but the RX8 would of course be its finest product if you could get one.
Fuel mileage is not great under any circumstances and there will be some oil consumption, both due to the engine's design. The RX8 is not turbocharged from the factory.
