Just as an FYI going from 238hp at the flywheel to 220hp at the rear wheels is about 9.5% drop on power where the normal range is between 15-20%. So drive train loss could reflect 202.3hp-190.4hp at the rear wheels with a less efficient drivetrain. So the RX-8 does pretty well. But of course you can always take into consideration that with the extra money you save on the RSX-S you could probably add a turbo and intercooler and make up for the drivetrain that way.
I think you misunderstood me. I said the dyno (~170 HP at the wheels) or more importantly acceleration times similar to the RSX-S indicate the car is only making 220 HP at the crank. If the HP at the wheels figure is so low and Mazda sticks to the 238 HP at the crank position, then the drivetrain is losing excessive power. Frankly, I think they are still overating the engine.

The RSX-S has a power to weight ratio of 7.23 (200 HP * 100)/2,767 lbs. Multiplying 7.23* 2,980 lbs. (estimated weight of the Sport Package) gives you about 215 HP. Using an estimate of the Grand Touring Package's weight of 3,029 lbs. gives you 219 HP.

Keep in mind that the RX-8 does have the DSC/Traction Control so I can hit corners harder with more confidence. This doesn't totally make up for a stiffer suspension but it does help.
This acts more like a nanny and I believe most who take the car on a road course will disable it.

My suspension was capable on the track let's say but when I had it dialed in for the track you wouldn't want to be a passenger driving on a bumpy road unless you were used to some serious Autocross on dirt roads. (No, the car never saw dirt roads).
That sounds like a sick car, I think I would sh**t in my pants when that thing was on the track! :o

Revhappy,

The MR2 was a blast. I would like to see the RSX-S vs. the RX-8 myself. I don't see what area you live in but I think it would be fun to put these two cars up against each other with average street drivers, no mods, and lots of smiles... I know that both cars have a devout following and they really are fairly close in most areas. I don't mean this as a challenge but more just for kicks. I love to race and we have the Spokane Raceway out here where the BMW car club often reserves the track for weekend street warriors with work shops on improving driving and fun activities. This would be a fun place to put that question to the test. They will be opening up in the spring... Anyway I enjoy a good debate.

For more discussion on RX-8 compared to RSX-S and other high revving cars, you can also read this old thread started by revhappy himself

https://www.rx8club.com/showthread.p...ppy+rsx+celica

Yeah, I was having a hard time deciding which car to buy and I still am now

i'm only responding to your amazement at how this turned into an RSX vs. RX-8 debate...it's because of your title...look at it! pretty much speaks for itself...
i know you didn't say that
i quote Outlaws eXtreme's reply not yours right?

I AM NOT HERE FOR SAYING RX-8 IS SLOWER THAN RSX TYPE-S

Hey 93,
Unfortunately, I'm on the other side of the country (unless they named Raceway Park in Old Bridge, NJ to Spokane Raceway. :p ). I think it would be close and come down to the driver in a drag race. My money is on the RX8 on a road course with its vastly superior brakes, but I still think it would be close.

I have been dieing to take my car on a road course and hopefully that will happen next summer.

RSX Type R vs RX-8 Type S please refer to Best Motoring International video. Not sure about what you meant by 'faster' but I think the Honda 4 Banger actually has a more usable torque curve, but the rotary revs faster and smoother.

Sad to say, had a run with my friends 91 Prelude SI, and from 0-60, it was tie, I drive an auto and he had a auto too. It was on a local road so I didnt want to go any faster than that. We have some bad torque

I have a dog that I often drive around with and in the RSX I can just lay down the back seats and he has plenty of room due to the hatch layout. It also prevents dog hair from getting on the seats. In the RX-8, there is really no where to put him. The car is also much roomier up front, and you don't have that bulge in the floor on the passenger side. True head room in the back seat is tight if your over 5'9". I use the cargo area much more than the back seats.
I'd have to concure. The RSX, like most honda's is just more practical for cargo. Reason being...the seats fold down. Yes, you can fit plenty of crap in the RX8 thanks to it's suicide door lay out, but what happens with the REALLY bulky stuff? I'm a movie theater manager, and I have to move prints around at least once a week. Sometimes two or three films at once. With my Civic COUPE, I was able to just fold the rear seats down and stack everything.

With the RX-8, I have to lay down a bed sheet over the back seats, and slowly roll the (SINGLE) film into the back seat. Worry about it scuffing up the center console none the less, and pray that if I have to make a sudden turn, the fill won't slam against the opposite window, or not my *** out from sudden breaking.

Fuel economy is genuinely better. At the moment...the there is a wider aftermarket array of performance parts and I have a feeling that they shall always remain much more affordable than the RX-8's aftermarket mods.

Its a big compliment for the RSX-S to be in such a close comparison with the RX8. I don't think that Honda ever imagined comparing its RSX with a car that costs 10 grand more and the same goes for Mazda...

My opinion as I stated before is that the 8 is a great car with a very problematic engine that makes topics like this one possible

The renesis has to give something substantial in trade for the poor mileage and other little bugs. That "something" has to be HP ! I would be driving an 8 with no remorse on MPG's if I had those claimed 250's under my foot. I like it better than the s2000 and the Z350 , I'm guessing that Mazda will have to do some radical changes to this engine if it wants the 8 to sell year after year

As of today I don't see any edge in favor of the Renesis compared to its piston cousins : Worse MPG's, Less HP's, and all the usual little issues related or normal to the rotaries.

I wish someone could convince me otherwise

Has anyone actually thrown a RENESIS on an ENGINE DYNO yet?
Besides Mazda R&D.

Yep...thats what I'm trying to figure out too...I really want to sell my S2000 to get an 8, but I really don't want a less powerful engine....if it had those claimed 250 horses, then I would reconsider....I'm trying to convince my self that the 8 won't be as slow as my S2000...which is slow compared to my previous car...Rx-7...I'll have to wait to see what goodies or what Mazda plans on doing in the years to come....Anyone know what would happen if they bump up the liter or motor size? Kinda what they did to the S2000? From 2 liter to 2.2 made alot of difference in torque and Horsepower. I know honda says theres no horsepower difference, but dynos prove other wise...atleast 20 horsepower different.

It's quite a shame because I think that the RX8 looks absolutely fantastic and my gf and I have been strongly considering trading one of our cars in for it. However the HP and MPG is such a huge concern. My car has 200whp with minor boltons i/h/e/hondata , runs 13.8 and gets 31mpg combined driving...

The reduced HP bugged me at first, but doesn't anymore. I can live with that.

But getting less than around 19 mpg is poor. I don't know if it'll keep me from buying it, but I'd like to see it be a little better, particularly as Mazda touted the Renesis as having improved fuel economy.

Anything below 25mpg is pathetic. Even a C5 corvette can get up to 29mpg on the highway!!! The car has 350hp!!!

Yeah, that's why my brain is having difficulty correlating 1.3L = 22 mpg when the Vette's 5.7L = ~30 highway.

It certainly doesn't seem like the Renesis is more miserly on fuel...

Talking

How did we get to the point on a thread comparing the RX-8 to the RSX-S that we start throwing Corvettes in? Whew! There are a lot of things to take into consideration here and for many people the rotary engines high rev and smooth feel is qutie the reason to buy the car. Many people are not experiencing the poor mpg (that I and some others are). This is the first year of the car and I am sure that many of our issues will be addressed. The EPA findings done on this engine were not in my understanding performed by Mazda. So why the difference on the production cars? Mazda has produced a fantastic car once again and I am happy with what I have. I could have Spent the $60k on the '04 M3 I was looking at but decided that even with the loss in hp I was still getting most of what I wanted. Maybe I can also look at how far the $34,500 will get me in gas. Now the poor mpg doesn't seem so bad. I would also like to point out that many people experience poor gas mileage when they purchase a new car. Many of the people I work around finance new autos and they have shared with me some of the concerns other owners have had about their new Hondas, GM's, Fords, Etc. So it isn't just us. And if it was more than it being a new car then I am sure we would be hearing from the EPA. They wouldn't want to be misled by any manufacturer and we would all have a serious complaint if this were the case. So rather can keep going on about this here on this thread move the mpg back to the proper thread and start a new one if you want to start comparing Chevy's to Mazda's.

Well, since we're throwing in Corvettes why not throw in the Accord?

3.0L V6 6 speed 240HP/212 torque (more like 260 with 93 octane), 3300 pounds (ouch) FRD

I've been averaging 21 mpg- but I drive like a bat out of hell, and I just got my first oil change so I expect mpg to increase.

I ran 14.5 my first time at the track and others have run as low as 14.3 stock.

Definetly doesn't handle as well as either the RX-8 or the RSX-S (I test drove both) but man, that torque throws you back in your seat! None of that high rev B.S. to launch either- optimal launching rpm is about 1800-2000.

Anyway, I've had the car about 2 months and I love it to death, the interior is very luxurious (better than the RSX and about the same as the RX-8) and there is adequate space in the back seat for passengers.

Oh, and it's only a little bit more expensive than the RSX-S- I got my 2003 for $23,900, which was about $100 over invoice.

There sure aren't nearly as many mods out for it as the RSX though!

I actually traded in a 2003 Accord Coupe EX V6 for my RX-8. The torque was great, but it was soooo front heavy, it wasn’t funny. I also thought that the brakes were nasty. However, I traded it in mainly due to my incompatibility with its ergonomics. I was never able to get comfortable in it.

Asking from the bottom of my butt: Do you get peak torque @ 1800 rpm?

That has to be sweet! However, not as sweet as an Audi All-Road Bi-Turbo!!!

EXACTLY why I traded my 2003 M-B C230k for my RX-8. The 8 just fits me well. And it's fun to drive, too -- that doesn't hurt!
