RX8 Type S has 285hp in GT4....is this OK? Should it be so?

Because as i know, most powerfull rx8 in japan is 250~ hp....
 
Yes, you shouldn't look at UK website when we are talking about Japanese versions ;)
 
It's listed at 246bhp, though IIRC when you actually buy it your garage lists it at around 285 as you say. I have one IRL at 230bhp...if they make the thing at 285 why can't we have it everywhere else? :irked:

Checking the JPN Mazda website, they list the Type S as making 184kW, which is 246bhp. So the listing is right. Why it makes 285 in your garage is beyond me, but then so many other JPN cars do this. Something to do with legislation capping output at 276bhp, even though in reality many of these cars made more power (Skyline for example). But then why not list the Type S at 276 instead of 246?!? :confused:
 
I've heard of a MazdaSpeed RX8 that comes with some tuning upgrades. Didn't know if it was released or whatever though.
I have an article on it in one of my magazines, i'll try to look for it and scan it for yas.

there is no way the rx8 makes 285hp. I own a 287hp 350z in real life and smoke these on a weekly basis

agreed, when the RX8 first came to US, it was listed 250hps. but after many owner complained, the manufact. finally admit it' only has about 225hps. your 350Z should be smoke them easily. But i guess it has something to do with the Type S in GT4.
 
Funny the RX8 and 350Z both completed the TopGear test track in the exact same time to the tenth. I don't think theres a huge performance difference, maybe the US ones are less powereful than the UK ones.

Well RX8 is known for its handling. I was talking about on a straight line, not track times. You might have to check the 1/4 mile times.

I'm pretty sure the rx8's dynoed in the factory at the flywheel and not the wheels. So I'm not really sure if those numbers do the performance of the car justice.
 
Mazda originally released the RX8 rated at 250hp. Owner's dynos however told of a much different story. The car put out roughly 170 at the wheels. A 240hp S2000 puts out 200 at the wheels. Mazda released an apalogy and offered a buy back or extended waranty for early buyers. I have driven the car and it realistically has 200hp at the flywheel and nothing more.
 
The 285 bhp in GT4 was based on the original specs and power Mazda intended for the RX-8 way before production when PD got the specs for it. It is a glitch of a kind. The GT4 production version still retains this 'power' when it should actually be less that 220bhp at the crank.

Mazda found that the rotary in NA form could not push hard without affecting emmisions and reliability. Such is the inherit weakness of the wankel although brilliant.

The S2000 like most Hondas on the other hand, is different outside Japan where they have 100 octane fuel. The S2000 in Japan will crank 245bhp from the flywheel but in U.K. and elsewhere it will be 10bhp less due to ECU programming and fuel.

My EK9 does only 175bhp at the flywheel in Singapore when it will turn 182bhp in Japan.

isn't the fuel in japan rated differently? i heard that its actually pretty much the same octane when rated the same way.

Yes, it rated differently. But the best fuel you will get in your country is equivalent to Japan and Singapore 98RON. No one but Japan has 100RON for mass consumption though.
 
And there are also RX8 Concept models...they are 285hp ...thats OK (because it was early version)....but TypeS should be 250 and not more....well..bug.. :)
 
Don't forget that a rotary engine has very different performance characteristics to a piston engine. Power delivery feels less punchy and smoother, so while it doesn't feel like 230bhp (also partly due to the lower torque) it is. The torque curve is also pretty flat.

And yeah, the 350Z may be able to beat the RX-8 in a straight line (if you're "smoking" RX-8s in your Z then the 8 driver doesn't know how to shift), but start turning corners and I'll be seeing your 350Z in my rear view mirror :trouble: :)
 
check the # again in mine it is at 248 or so....350z has more tourque so in straight line you will smoke an rx8...but once you start turning the rx is so light an nimble it will corner faster than your heavy 350...but if you only drive straigh i understand how u think the 350 is better....btw....can u seat 4 comfortably.....?
 
Yeah, I think "full-size rear seats" in Japan means "small-child-sized rear seats" in the rest of the world :) There's no way a large adult could fit comfortably in the back of my 8, and I doubt anyone could do so behind my seat (I'm pretty tall). But then again I didn't buy the car for the back seats 👍
 
@eastley: umm...okay, what's your point? The Z has more power? Okay, but the 8 is still faster around corners :sly:
 
dking, yours was sold to you at 248 before Mazda issued a press release stating their mistake and dropped the number to 238. THIS DOES NOT MEAN YOUR CAR HAS 248. Your car may be lighter but the 350z posted better track times in a comparisson in Car and Driver. Plus I ran a 13.8 1/4mile stock where the quickest anyone has achieved is 14.6 in a RX-8. If I wanted a back seat I would have bought the G35 coupe which is still faster than your car. In fact the g35c beat the rx8 and Mustang Mach 1 in a comparo by car and driver.
Any time, any place, any track or strip I will smoke you and your wankel so know your place which will always be behind me smoking on my tailpipes.

For now...

(in case you didn't know, some suppliers in the UK are considering 100RON)


macrayz - The RX-8 doesn't have a Wankel. It has a Renesis. The design is as different as DOHC is to pushrod.
 
The RX-8 is not faster around the corners because it can not accelerate out of them becuase lack of torque. There have been many comparisons of these cars and the Z always wins. I have read lap times at button hill raceway and california speedway inner course where the Z lead by several secconds. The Z has better lateral acceleration; .90g versus .88 and a higher slolam speed which dictate cornering ability. The RX-8 is not a true sports car and an embarassment to the RX name the RX-7 fought so hard for. Shame on you mazda and shame on you dking for arguing without facts to back it up. :dunce:

Back atcha, Mr. "you and your wankel".

Not every vacuum cleaner is a Hoover... (although as I type that I realise you may not actually understand that, as it's probably highly regional...)

The Renesis is a rotary, not a Wankel.
