Mazda Rx 8 With 1300Cc Engine?

machan though the engine capacity is 1.3, it s very powerful. it is a Renesis engine, and gives u a power more than 200hp.

They are called Wankel rotary engines...Renesis is just the name Mazda calls their newer generation of the rotary engines.

hi..looks like u are interested on the rx8 :yahoo: u will get to know a lot of details about the rx8 if u read these old threads,they have most of the answers for your questions.....according to the following threads rx8 will be a superb car only if she is treated as she should be

if you're thinking of buying one, might i suggest not looking at this from a regular 1300 piston engine. because, that's what one would jump to compare it with, it you're new to the concept of rotary. to be frank:

1. its not the same fuel consumption as you might expect from an inline 1300cc engine

2. its not the same tax bracket. RMV taxes it at 2600cc, so you have to pay laksiri tax.

3. its nowhere near as easy as maintaining (or not, rather) of an inline. parts need to be swapped a little more frequently than the inline.

but that being said, rotary's are amazing things. quite a novelty to own one. all the design cues on the RX8 are rotary based. from the seat headrest holes, to the foglight covers to the rear stop light...

Not all models of RX-8 gives you power over 200 bhp but even the lowest powered models come close, so not a big deal.

Rotary engined cars are a different animal to drive as well as to maintain, if you apply conventional (driving as well as maintaining) to it - it wont really respond well.

One thing to note for someone who might inadvertently stumble in to the allure of RX-8 is that Mazda had to discontinue RX-8 in 2011 (spirit R) due to economies - the car could not be sold in EU due to fuel efficiency (and some other parameters) not meeting strict EU criteria. So we actually don't hv any Mazda rotaries selling at this moment (I can't think of any other major rotary make selling atm, but that's just me) until 2017, when they will hopefully revamp the RX-7.

Most local specimens of RX-8 on auto shift might do 5-7 km/l with later models yielding better consumption's than pre-2007 models.

So if you're happy with that and thrive on high RPM's, then this is probably a good investment - specially if you can get hold of a spirit-R model which are limited in supply but with better looks and fuel economy which might give you a better re-sale value (or antique value in 2060, being the last production model of RX-8 rotary!).

I'm looking for one .. then again my company pays for the fuel! :D

my best mate has an RX8. It is a 2003-2004 model I think. The type S with a 6 speed manual. I've had the pleasure of driving it both in Colombo and outstation several times and it's an absolute blast to drive. Superb handling, well weighted steering....and the sound of the rotary when revved...boy it does put a big smile on your face! Light as ever, so once you rev it past 6000 rpm the car truly comes into its own. Clutch and gearbox is a bit clunky and heavy so it takes a while to get used to, especially in Colombo traffic

Its very thirsty, but the problem is the suspension in that car is way too stiff for lots of our roads. I don't know if it's an inherent problem with RX8's but the car bottoms out with 4 averaged sized adults. I know my friend has had to replace the shocks and the mounts a few times, and the latest issue was the steering rack when the EPS stopped working. Driving on potholed uneven surfaces is very uncomfortable in that car. Mind you, I am used to stiff suspension as my daily driver has 18 inch wheels and sports suspension but the RX's ride is too hard for Colombo roads to the point you almost feel you're destroying the car!

He's also had a few electrical problems and cooling issues, which he has found difficult to sort out despite spending a lot of money and going to specialists.

Again I am not discouraging anyone from buying the car. My friend may have been unlucky. It's one of the most fun cars I have driven. Just make sure it's properly checked out and you need to have some deep pockets to sort out any potential issues if you are buying an older car. There are lots for sale at the moment.

Why exactly 2600CC?

Why exactly 2600CC?

I have no clue how the RMV came up with that number, short of guessing that the blokes had a chat over some tea and vadai and thought, "let's double it so it falls under the tax bracket. It has to be a lak-Siri car if it does only 6kmpl no?? And sport car no?" Etc etc

Rwd raises some important point. Had no idea it had inherent suspension issues. Our roads however are improving by the day, so it may not be a bad thing. Just ask VVTi... He jizzed himself many times driving to the east coast yesterday

I think they came up with the 2600cc figure by taking into considering the actual chamber volume rather than swept volume, since two individual combustion spaces are created inside of one rotation of the rotor.

I think you're spot on. Infact EU regulators treat it the same way iirc.

Isn't stiffer suspension an issue (or a positive for some) in all Mazda's? I hv driven only one RX-8 and it didn't feel any stiffer than my Axela. It improves handling a lot - just not on our roads.

(but the roads are getting better, aren't they?)

I like stiff suspension too. But the RX 8 suspension is definitely way stiffer than the axela. The two are non comparable. The car my friend has is the Type S with 18 inch wheels and stiffer shocks. Maybe you drove the normal version? i know our roads are better now but its still very uncomfortable. Even a slightly uneven surface at high speed can cause the car to bottom out, especially when there are 4 adults in it.

I drove it to Kitulgala and back 2 months ago. So decent roads but not billiard smooth. Whilst I enjoyed taking the bends with confidence, the car kept bottoming out whenever I hit a bump on those unevenly carpeted roads. So I had to slow down significantly. I had a blast driving it but that put a dampener on the whole experience. My friend had to do some suspension repairs soon after.

Within 3 rotations (1080 deg) each face of the rotor produce one power stroke. So the actual displacement during 1080 deg rotation is 1.3x3 = 3.9l

To compare it with the 4 stroke piston engine where all cylinders complete a power stroke in 720 deg, we need to divide it by 1.5 ( = 1080/720) which result in 3.9/1.5 = 2.6l. So the RMV is correct in this sense.

From Wikipedia: https://en.wikipedia.org/wiki/Mazda_Wankel_engine

Ironically, road tax for the RX-8 in Singapore is less than that of a corolla. It is purely based on the 1.3l capacity

Yep, a normal 2007 auto - and it really didn't feel any stiffer than my 2005 Axela on Colombo roads and while it felt low, it didn't bottom out anywhere with 2 people in it. So obviously, they hv tuned it much stiffer in the Type S.

I recently came to colombo and was surprised how bad the roads there are compared to here in Kandy! :o

It's very good on patrol machan. because it's got a 1300cc engine no. it does about 11.732km/l in colombo. you can pump 1000 rupees patrol and drive 70km before patrol light switches on. after that you can drive for another 70km with the patrol light on. outtasion it does about 15.325km/l.

thanks for the reply machan. one of my friends own a 2007 rx8 , 1300cc aswell, he says its pretty bad on fuel consumption. i dont know what exactly he meant by bad, but im guessing its lower than 10-12 km/l range ?

All you really need to know is this; The RX8 is not the sort of car anyone concerned about fuel consumption should look at. THAT IS NOT THE POINT!
