My recommendation to Mazda for 2007 RX8

What do y'all think? I came up with these after spending countless hours reading reviews and online forums. I was researching the new RX8 'cause I wanted to buy one. But I found these flaws.



Offer the following features as standard features on the 6-speed automatic
o Limited-slip differential
o 18-inch wheels and tires
o Larger front brakes
o Sport-tuned suspension
Fix the horrible fuel management for better mileage per gallon
Fix the oil burning issue
Fix the tricky uptake on the clutch for the 6-speed manual transmission
Increase the horsepower and torque figures to match with that offered on the manual version
 
Ill address this is the same order you put it out :

1) if you make more things 'standard options' you raise the base price of the vehicle, so less people can get into the market, even on the low end....so you lose sales as you price the car out of the maket.

2) Limited slip is standard an the automatic with everypackage but the base model, I know you suggested it be standard on all models, but again it affects the price point. At leasts its not the 350z where you dont get LSD on the base auto or manual.

3) Pretty much the same as above. Standard on all but the base.

4) Also same as above standard on all but the base.

5) Yet again standard on all but the base.

Part of the thing with the LSD, 18 inch wheels, big brakes and sports suspension. A Lot those things come standard on the base 6speed so people can get a cheap platform to go racing. They are not standard on the auto cause mazda wants to price the auto to be cheap so that people who just want the looks of the car can get into it. Not a lot of auto buyers are after performance.

6) The fuel management is not really an issue, I dont know much on the auto, but on my 6speed I get ABOVE the epa estimates. 20-22mpg city and 24-25 on the highway. There are owners that get as much as 28mpg on the highway. Yes the car isnt as economical as far as fuel consumption as a piston engine of similar power, that is just part of the trade off of getting the car with a rotary engine. I gladly trade the 5mpg more I used to get with my miata for the extra rear seat and the power band from the rx8. Every car is gonna have its good and bad points. Mazda has done a lot of work with new ECU software since the car came out to help power and economy. Personaly I feel that the power of the 6spd is pretty good for the quality of the suspension and brakes, its all balanced. If you were to just dump more money into the motor without looking at the rest of the car it would feel unbalanced IMO.

7)This statement makes me feel that you might not know much about the rotary engine or the rx8. All rotary engines are designed to burn oil. Its part of how they work. The only way to lubricated the apex (corner) seals in the motor is to put some oil in the combustion chamber.....and because of that some oil will be consumed. You cant change that.

8) Tricky update of the clutch? Im not sure what you mean. My miata as well as other cars I have driven had heavy aftermarket clutches. Maby thats why the rx8 clutch feels so easy to me. The clutch is very light and slips easily...something I dont like, but I think it would make it very easy for first time manual drivers, or people who tend to have trouble starting from a stop in a manual. I generaly bring the revs up to about 1200-1500 and slip the clutch for about 1sec and im away and the clutch if fully disengaged. I have seen many other drivers that have trouble with the fast reving of the engine and slip the clutch from 2-3k rpm to get started. Ouch!

9) This is something we could all debate all day. My car dyno'd (stock) 165whp on a mustang dyno and 185 on a dyno jet. Both these put the crank power at about 220-230. The trap speed of the car (95mph) also suggests (for the weight of the car) that the power is around 220-230. Tha is pretty close to the revised HP number. Also as my dyno was done in close to 95*F weather with high humidity and the car was hot from driving to the dyno. I think the power figures are pretty accurate. Maby your one of the people that are just not happy with the power even if it is 238hp or whatever. I dont know what to tell you. I think the car stock has good power for what it is. The rx8 is not a sports car.......like an vette, 350z, gto, ect. It is in the category of 'sports-touring' or 'grand-touring'. Its a sporty car yes....but you have to remember, mazdas Idea wasnt to make a car that would be a top of the pack performer. It was to build a reliable and functional car that could be fun to drive and still take the family on vacation. It put the rotary motor in the car to help get people back on the rotary bandwagon and see that the engine is a good platform to build off of. That way down the road if they do come out with another rotary sports car.....people will be interested and not slump it off as another car with that 'problem rotary motor'. That is my thoughts. If I wanted a sports car I would have gotten a used 02-04 Z06 corvette, I wanted a fun to drive, functional car that could go on road trips and put around town....but still be a nice ride at an autox or track event. Its a good platform to build off of....and its downright sexy!
 
Also as far as MPG (since MPG and HP are the 2 biggest topics when talking about the RX8) :

Almost NO cars on the road get their EPA miliage. Why is this? Part of it is driving style and part of it is how the tests are done. I get MORE than the epa estimates....its a toss up.

The EPA miliage is off, thats for sure, for most people, because of the way traffic actualy moves in the city, and using air conditioning, and lots of stop/go traffic, ect.....miliage is less than EPA.

I only use the EPA miliage to compare cars, if car A) get 30mpg and car B) gets 38mpg .......then I will say that givien the same conditions car B will always be more efficent. Dont expect to get the miliage.

I tend to have little idle time ( I dont drive in traffic ) and while I cruise at the same speed as everyone, I start from a stop slower.

Friends have switched cars with me and I get higher miliage than them in their car, and they get less than me in my car.

Just by changing your driving habbits you can get 2-4 mpg more EASY.

Sure I would like the MPG to be more than 22mpg, but Its better than the 14-16 some people get. 40 bucks to fill up takes me 300 miles. Im ok with that, cause I understood that coming into ti.
 
Very well said KYLiquid. To me the car is perfect and I still love it. I never get bored of it. Zoom zoom!
 
ok a real idea for 2007

release the mazdaspeed RX8 and stick in a turbo :)

Have you driven any RX-8, or are you merely BSing based on what you've read?

Drive the car and let us know what you think. You'll forget about your arguments and suggestions.

Becides, you're too late. Mazda's already done with the '07 RX-8 so you won't make a change...you wouldn't make a change anyway...
 
the manual 8 just has more power from the way its ports are laid out correct? I could see them doing that for th eauto but everything else falls under what KY said.

In the US for the 2004-2005 RX8 we get 2 cars :

4speed automatic with a 4port 2rotor engine
6speed manual with a 6port 2rotor engine

The 4port motor had a lower redline (cause the trany couldnt handle the 9k rpm redline of the 6port motor and the 4port didnt make power up there anyway. The 4port motor was geared for more TQ and less HP.

Starting with the 2006 model you can get the RX8 with a 6speed automatic using the 6port 2rotor motor. This version of the automatic bumps the power up to 210hp, but it is still lower cause of the cars lower redline. So the trany will survive.

The automatic wont get anymore powerful unless they build a trany that can handle the super high RPMs...and I dont see that happening.
 
the automatic on the rx8 sucks anyways. click the upshift paddle and wait a few seconds, then it goes into gear. its weaksauce
 
don't forget to tell your mom to redline her auto 8 daily Roy. The motor NEEDS to be revved to stay strong and healthy :)

Now this may sound like a retarded question beings that I dont knwo squat when it comes to the rotary engines, but why rev the engine for it to stay in good condition? Or your BSing or does this have to do with the oil burning/lubrication issue. P.S. I didnt know the rotarys burned oil due to the lubercation... I almost bought a 88 rotary car (wasn't a rx7 but some other mazda car with a porche looking from end on it) but didn't because I didnt know enough about the engine.

no BS'ing here, it is well known in the rotary world that rotary engines are designed to be revved, and should be run through its whole rev range regularly to keep all the mechanisms operational and reduce chance of carbon buildup inside the engine.

use a motor oil with low ash content to further reduce chance of carbon buildup.

btw that '88 rotary car' that looks like a Porsche IS a RX-7, it's a second gen RX-7, the F&F RX-7 is the 3rd gen....

You have to rev these things? Dammit.... why didn't anybody tell me that about my FB?!!?!

very funny dan. (poke)

I was just doing a google search on the car but couldn't find one that looked like the car... Whats a good way to tell if the engine is any good in that rx-7... btw itsa n/a car thats been gutted.... also would the int be pretty easy to get as most of its either trashed or or missing? Irc it had round headlamps

Yep it was the Rx-7. I own one.

Yup, terrible. I use the auto-stick instead of the paddles when I have to drive an auto 8 on the road, luckily it's a rare occurance(we rarely have them in inventory because no one wants such a car).

But hey you still get the shift beep at the redline with the auto. LOL
