rx-8_or_?

This is hilarious: http://www.windingroad.com/articles/...=Nextscreen#22

All the cars have turbochargers, superchargers and what not to get above 100 hp/liter, except for a few of the Porsche's and up there at #4, "1.3-liter two-rotor produces 178.46 horsepower per liter." If you didn't know about the rotary engine this would surely look like a typo!

I think the Renesis is still the highest HP per liter for all production vehicles. Correct me if I'm wrong.

Damn...twin S/C. Need to do some homework on that.

RX8 is the only N/A of the bunch. Go figure. The problem is that we're all hung up on HP, not the area under the curve. N/A 8's look like the two strokes they are compared to the company it's keeping in that article. If jet turbines had displacements, they'd cream everything, but only above 99% RPM.

Horsepower/liter is COMPLETELY useless. It has absolutely no effect on the actual driving of the car. If anything it actually hinders how sensitive a car is to bolt ons (exception is cars with forced induction) since the engine is that much closer to maximum efficiency. A Corvette Z06 has a shitty horsepower/liter ratio compared to an RX8. Slap a cold air intake on both of them. The Z06 will gain about 15 more horsepower to the wheels (the LS7 isn't even trying at 505 bhp). Don't think we need to go over what a CAI does for an 8...

Anyway I'd look at horsepower/RPM. At least it has some relevance to driving. I find that usually its only ricers that bring up horsepower/liter. Makes them feel special somehow.

Cool story bro

Good find. Kinda cool that our cars are mentioned in an article with Koenigseggs, Bugattis and Porsche 911 Gt3's.

It's a cool article, but it really depends on how you calculate displacement in rotaries. Mazda claims 1.3 liters for the Renesis largely for tax reasons.

agreed, by all rights it isnt a 1.3L. hell even the european union recognizes it as a 2.6L but if talking power dense, your ultimately referring to size or weight, both of which the rotary does well.

Marklar

^ Yep it's the size and weight that really matter, which is the key to the 8's amazing handling. It's light and small enough to be tucked right where it should be.

HAHA good find.

rotarygod

The way I figure it the rotary makes 89 hp/liter. It just isn't a 1.3L engine regardless of what it is classified as on paper. It is very small physically though and for that reason I would give it the greatest power density of the bunch.

hey thats what i said :P

2 Mazdas in that list is pretty sweet though. beat BMW :p
