What cars currently match the RX-8's ~178HP/L?

As above, what cars in serialized production today match or exceed the RX-8's HP per liter?

I'm kinda struggling to come up with examples...

Yamaha R1: 180hp/liter... Not a car, but just thought you'd like to know.

But seriously. Why does it matter? HP/L is a useless number to hang your hat on. I mean, seriously, torque is all that matters for get-up and go... And unfortunately, the RX-8's abysmal +/- 130 ft-lbs isn't going to make it lightnening fast on the straights anyways.

It doesn't matter...

It is a wankel, don't compare with others.
If you do, you better use 2.6 liters.

wards top 10 engine award classifies the renesis as 2.6L when it won the category a few years ago.
neways, hp/liter dosnt mean much in terms of real world performance or fuel economy.

Sounds like someone was bragging cuz his/her car was faster, and he came up with this as a way to one up the person. lol

If you want a comparison, do some real world comparisons like magazines do. Ricer math is FTL

I know it's not a great measure of perfomance. I was just curious. Jesus Christ. I don't even own an RX-8 (yet).

Also, can someone explain to me why the Renesis is classified by some in the 2.5-2.6L category?

because of the number of combustion events revolution when compared to a 4 cycle piston engine. there is a long thread by RG explaining all of this you should search for.

hp/lb is a more reasonable comparison of a cars performance.

the rx8 weighs in at ~14 lbs/hp.

lol.

Here's an earlier thread with this video ... not sure if it was the first, though ...

I can't, for the life of me, figure out 100% why the Rotary Engine gets 'poor MPG'
