Yes it is- they are saying the engine has the worlds highest specific output- which is clearly wrong since the S2K's 2.0l is still in production....

 

RX-8
232hp
1.3 liters

178hp/liter

 

Doesn't count because it's a 2-stroke.

EDIT: According to the FIA, a rotory's displacement needs to be multiplied by roughly 1.75 to make it comparable to a piston-based motor. 102 HP/L.

 

That's amazing.

 

yes, thats a record...in the rotary world.

 

A rotary is not a two-stroke, and even if it were, two-stroke displacement is measured the same as 4-stroke displacement. 250cc two-strokes are not referred to as being 500cc.

Applying the FIA's arbitrarily chosen "equivalency" factor does not mean that a 1.3 liter rotary is *really* a 1.3*1.75 = 2.275 liter.
The fact that they have an equivalency factor is because rotaries DO make way more power/displacement than piston engines.
In the case of RX-8 vs. S2000, that would be 178hp/liter vs. 108hp/liter (120hp/liter for the AP1).

178hp/liter is, I believe, a record not only in the rotary world, but for all naturally aspirated production cars.

But 600cc sportbikes make more like 190/liter...
