Nice one
However, he shouldnt need that, he build engines for a living :/
Scary huh..

rx8 are slow lol jks

eg6 ftw hehhheheh

old but nice clip

Both are good cars...but one takes more fuel than the other...thats all...

Tsukuba's straight too long? LOL. It's not long at all.

BTW, you have to remember, it is the AP1 that is nervous at the limit. The AP2 is less. But I have a Best Motoring video showing the difference at the limit between an AP2 and the 350Z. It is a very big difference and what Tsuchiya said, at the limit in a 350Z, you are only 8/10ths committed. In an AP2, you are 10/10ths committed. If he can say that about the AP2, imagine the AP1!

Ummmmm that Tsukuba straight doesn't look long? Take a look here http://www.jasc.or.jp/outline/index.html . It is a 433 metres long straight and is one part of the circuit where faster straight line cars always have a chance to overtake the slower ones.

I also don't agree that the AP1 has such a big difference with the AP2 although obviously AP2 is slightly less nervous. My point was, even when the Japs were driving the AP1 they already unanimously gave it the vote as a top driver's machine with great at-the-limit control ability whereas the local journos bagged it for being too nervous and twitchy. The way I look at it is however, even if the S2000 is twitchy at the limit it actually won't bite like an MR2. Its twitchiness is its advantage because the top drivers can extract the most out of it!



And what hasn't been mentioned yet?

Mazda are actually trying to make Hydrogen rotaries out of the RX-8 platform. Well they already have. So I fail to understand the philosophy behind it as yet, because if rotaries really aren't that fuel efficient then aren't they putting too much effort into the wrong system to showcase their environmental products?

433m is SHORT. You know our favourite Wakefield Park raceway? It's considered a short and tight track. Even so, the main straight is 900m long! Yes, more than TWICE as long as Tsukuba!

The reason why the S2000 is twitchy at the limit even with a suspension revision in AP2 is because of its 50:50 weight distribution. Without electronics to help it, of course it is prone to spinning at the limit. Same case as the MR2, which has it worse because of the rear bias in weight distribution. Being twitchy doesn't mean that you can extract better handling/grip out of it. It means you have less of a buffer to catch it before it spins.

THREE reasons. First, hydrogen is a renewable resource and you can use more of it without getting a slap on the wrist from environmentalists. Second, they were showcasing that the Renesis did not require many modifications to use hydrogen as a fuel, as compared to a piston engine. Third, if they made a hydrogen Mazda2, Mazda3 or Mazda6, it would just be labelled as a greenie car. Using an RX-8 it shows that people can have performance while saving the environment (having your cake and eating it ).

Now i really start to wonder, where did you get your facts from...are you in that field? or you're just stating your opinion???...i'm just curious thats all...

Read the press releases Also, being a chemical engineer helps with fuel/oil details.

Here is the press release on the hydrogen Renesis, if you are interested. http://www.mazdausamedia.com/article...ticle_id=18623

Well Wakefield does have a long straight but that doesn't necessarily make the Tsukuba straight short. Wakefield is tight and twisty at the back but that's not to say it doesnt carry a long straight. Granted the Tsukuba straight is not extremely long but it does already give two cars that are usually very similar enough in straight line performance, the chance to pass the car infront.

As for "Being twitchy doesn't mean that you can extract better handling/grip out of it. It means you have less of a buffer to catch it before it spins."

Well I disagree entirely because the first part of that sentence and the second part do not agree with each other.

Perhaps instead of saying twitchy I should have used the word Agility. I agree that you have less buffer to catch it before it spins, but one must consider that during the transition from 8/10ths to 9 and 10/10ths limit of a car's track ability, that transitional phrase is when additional seconds can be reduced from the circuit time. Hence cars such as S2000, MR-2s and M3s can be driven on the limit but will spit back at you if you are not capable enough to handle them. However, cars like the 350Z are easier at the limit and turns to understeer unless you provoke it to oversteer first. In fact the E46 M3 is similar enough to the 350Z compared to the older versions. They are safer, but ultimately, won't be as fast on the track for a professional driver driving a more agile car.

Bump for more "Who's bigger" posts...

[EZZY]

size matters

So, which part of the RX-8 has F1 technology??? The renesis rotary engine??? I hope not because all F1 engines are piston.

Mazda doesn't even have a F1 team.

No but they had a Le mans team...
