Wow, you can really see the weight transfer when turning at speed.. I would love to have a translation.

Good Comparison.

The Eunos Cosmo is an awesome car, would love to get one.

Presumably a 20B Cosmo? If so hardly fair on the drag test! Actually I'm surprised it was so close!

If they went around the track a few times the Soarer would have won, as the Cosmo would have had to stop for gas again, and again, and again...

Nice clip.

I should have learnt Japanese.

The Soarer is really in its element with high speed driving like that.

Yes the 20b Cosmo is fast, will about always beat the Soarer down the 1/4. The 13b Cosmo would be a bit slower though.

More power in a probably lighter car. Of course the 20B fails in economy, refinement and reliability, and the Cosmo is pretty average looking, so the Soarer is still going to be the better GT. Pleased to see it was so very close on both the drag and the track.

Funny how the drivers kept reaching for the gear leaver! :-)

The cosmo is less shaky around the track, plus their fuel economy isn't that bad when driven normally, it's only when you stomp on it that rotaries drink.

Still with the K's I do, I'd be replacing the apex seals yearly - bugger that.

Watch from 5:30 - drivers keep reaching down to the gear selector even though both cars are autos - perfect example of conditioned response!

I agree, they are a typical Mazda Eunos, an attempt at a refined vehicle but don't really hit the money that well. God knows why they went for a Rotary... stupid in my opinion.

The TT Soarer they tested is just better on all levels, bit of a no brainier to what is better.

Look closer, they are not just reaching down but manually shifting the auto.

Perfect example of how to be in complete control of the vehicle.

The driver of the mazda is overdriving it and going slower than the car is capable of, I think you will find it would actually be a notch faster than a soarer both in stock form around a race track either way not a great deal in it.

How many kms a year do you do. Apex seals have a life of anywhere from 100,000 to 300,000km pending on how well the engine is looked after.

Was hard to tell with the image being so blurry, but with the headphones on you can hear the car shift so you are right.

Maybe possible to get to 100,000 on a N/A rotary without cracking it open, but my workmates turbo 13B was every 30-40,000KM. Admittedly he drove it pretty hard, but he also took very good care of it. I'm around 35,000 a year at the moment. I've never heard of a rotory of any make or model making 300,000KM without new apex seals - probably possible if you drive it like a nana and service it every weekend though.

Plenty of rotary fans that will argue that point.

I know of guys that have highly modified Rx7 with turbo engines that regularly do track work and have engines last considerably longer than that.

My uncle's RX3 had a very hard life don't know exactly how many kms (he had it from new and sold it a few years back) but the car was completely worn out and the only good part left was the engine. He used to rev it beyond the rpm warning which was about 11,000pm and when he changed gears the revs were still above the rpm warning estimated around 14,000pm gear changes.

The only down side to a mazda is the cost of parts, their prices for common service and replacement parts are 4-5 times as much as Toyota, Nissan, Holden ect.

He was a fussy bugger - first sign of reduction in compression and it was tear the motor down and replace all the seals. Also had a turbo timer with a ridiculous delay on it. He'd park in the car park, come up the stairs, log into the network, get his coffee, and the damn thing would still be farting away in the car park.

I guess the lack of experienced rotary experts would be another problem. Most common garages wouldn't want to touch them. Mind you, seems that you guys in Aussie get that problem with any Jap import anyway.

A little beyond my knowledge but I was under the impression that the seals would work perfectly then fail suddenly so no slight drop in performance but I could be wrong.

For performance applications there are better seals they are slightly more expensive than the orginals and have proven to be reliable with massive amounts of HP, track work.

What kills the seals is heat get them too hot even a little bit just once and they will be stuffed.

Another problem is that many Rotary owners use Synthetic oils in them which most will quickly accelerate the degradation of the seals and require rebuilds within less KM's.

I think some of the aftermarket seals have a reputation for wearing unevenly which can lead to degradation in compression. Basically they are just a big blade shaped thing, so I guess if the blade doesn't have a 100% straight edge on it, gasses will escape around the rotor lobe. Supposedly Mazda's OEM seals are more resistant to this kind of thing.

Catastrophic failure is apparently a problem too, I've read of seals crumbling and damaging rotors and housings, though again it seems to be mostly with after market seals as the factory ones are softer and don't do much damage even if they do fall apart. Don't know anyone that its happened to though.
