Title: RX-8 vs RX-7
Post by: Fenix2k on February 15, 2004, 11:30:41 AM
Hey all,

Not sure if this has been posted already or if its in the right place but as someone who has to wait a while before buying his first rotary motor :( :(  was wandering if there was anyone who has either test driven or owns an RX8 that has also owned/driven an Rx7, which is the best model overall??

The 7 should be faster being turbocharged but does the handling balance of the 8 counter this?? Uber confusing!!!:confused:

You ought to watch Best Motoring International #8, where both (plus a MX-5) are taken down the Togue.

Well, I\'ve never driven an 8 but on paper the RX-7 looks the better car. The RX-8 seems very underpowered compared the 7 but Clarkson raved about it on Top Gear. Of course, you gotta love those rear doors of the 8 and the interior is terrific too - loads of gadgets to play with! But overall styling has to go to the 7 - it looks fast even at a standstill. And one of the best rear-ends in the motor-world! The 8 looks a little too much like the Mazda 6 for my liking. Whack a Veilside kit on it and then we\'re talkin\'... :D

Hello and a warm Welcome to from all the MRC team.

l know there are video clips of this out there but during development of the RX-8 Mazda put the last model RX-7 made [Oct 2002] up against the RX-8 around the track at Laguna Seca a Mazda owned track in California and your right they both produced identical lap times!

This is due to the fact that an RX-8 WILL out handle a third Gen RX-7 thus compensating for the power difference.

This has come about due to having to eliminate the \'B\' post the MAZDA engineers made the bodyshell so rigid to compensate that the happy trade off has been a phenomenally good handling car because if you are able to hang your suspension onto a stiff structure it will work PROPERLY.

Hope this helps.

Im still waiting to destroy an RX8 though.  Track, strip or street wherever it likes :bandit

They are aimed at different markets really.

Surely a 7 would outdrag an 8??! (thinking traffic light GP\'s here...)

Cheers for the info.

Clive: how do you think this would compare in a fast road / everyday use situation?? as you dont drive around on-limit all the time (well almost!!) to exploit superior handling, logically this would make the 7 quite a faster road car??

lee i beat you to it!
The other day i was driving down the A13 in the inside lane when i see a blue skirted up rx8 coming down the outside lane, it had a private rx plate. being my sad self i got exicted that there was a fellow rotory on the same stretch of road as me so i put my arm out of the window and waved but this fella totally blanked me, i came out behind him and we were doing about 70 when i see the back of his car drop and peel off from me so into 3rd i went and by the time i got to about 95 i was ready to pass, he stayed in front of me till about 110 then he moved over and i cruised passed, he wouldn\'t even look! ha ha, long live the seven!!!!!!!!!!!!!!!!!!!!:)

Sorry Clive, but this was Mazda propaganda.

Watch Best Motoring International #8 - the drivers have nothing to prove.  On teh track the RX-7 is comfortably quicker than teh RX-8.  On the Togue run (down hill street racing), the RX-7 was faster, BUT the RX-8 was far closer than they expected - all (in both tests) due to the softer suspencion setup on teh RX-8 and the fact they felt the RX-7 was too stiff for the bumps and dips of a road surface.

Yay to Tom! I\'m finding that all the 8\'s I\'ve seen are driven by people who seem a little ignorant to the rotary community and seem very puzzled when I flash them or wave.

As Lee said, they\'re aimed at different markets. :)

Yep, there is a Red RX-8 one in Walton, seen it a few times,now. I have waved to it when driving the RX-2, and the RX-7, but she seems oblivious  :-(((

Ive had the same thing happen, i sat on the inside lane waiting for this RX8 to pass to give him a wave but got totally blanked!
There should be some sort of rotary appreciation test before people are allowed to buy one :D

At least its not just me that gets blanked by all \'8 owners then!! Theres quite a few in Maidstone, not one of which will acknowledge the rotary love!! We\'ve got respect for them! Maybe its cos they don\'t even know their car is related?

I got blanked by a \'7 owner as well the other day, and he was next to me at a set of lights! Silver late (post 96) model with 18s. Git. Think someone should have a word!!!!

I know of two people who tested the acceleration of a standard RX7 3rd gen and an RX8 and up to 140mph the RX8 was still with the RX7!After that point the RX7 pulled away.It is likely on a track that an RX7 would not get above 140mph unless there is a very long straight,which most circuits don\'t have.
I also will back up Clives comment that the around Laguna Seca the RX8 did match the time of the RX7.It maybe that the track was better suited to the rX8 but no 2 tracks are the same.If you tried this exercise on a different track you would get different results.
Kind regards

I gave one a good spanking on the A3 from around 90 mph top 130 but admittedly I was not in a complete stock 7 and yes the 8 driver was trying. I think I will go for a test drive in one soon to see what they are really like for myself.
There\'s absolutely loads of them about which is good for the rotary seen in the UK.

I think that many people who are driving these cars are not of the rotary mind set.I think some are afraid to rev them when they have been run in.
If you keep one in the 7000 to 9000 rpm range you will see that it is a quick car and can get you into high speeds very quickly,it is not so in your face as a 7 because of the 7 having 90% of its torque low down at 2000 rpm.
So get the RX8 singing and you will see.
Kind regards
Carl:D

As by coincidence, hopefulyl tonight a friend will be dropping off a DVD ripping application with me.  As BMI is not avaiable in the UK I will see if I can cut various sections of it and try and find some one to host those vids for me.

It should eb noted that the drivers do like the car, unlike the Z350 which Gansan describes as unfinished.

Totally agree, although I don\'t think it\'s limited to rotary. I found driving the rotary was like driving any NA car with a narrow power band (if I may use such an old-fashioned term) - reminded me of a go in me mate\'s rally car (205 1.9GTi - although add 3000 revs for the Mazda :cool )

In fact that put me off the 350... such a wide torque curve it may as well be a turbo.

The problem is 90% of people don\'t understand torque, power, and gearing, and if you just don\'t get it you won\'t get the best out of an 8. I\'ve ordered my 8 specifically BECAUSE it\'s a total go-kart with short gearing and six ratios! Much more fun to drive than anything else I looked at.

(It\'s similar over in the 300ZX world... "I bought an NA and it\'s slow" or "I bought a 350Z and it\'s slow" and it usually turns out they\'re changing up at 5000 revs.)

I\'d also agree with comments I\'ve seen here... lots of RX8 owners don\'t understand the history and they\'ve bought it as a new car instead of their 3-series or A4 or what have you. I think they\'ll be fed up when they realise they have no torque and low economy, and we might see a few nearly-news around next year in Autotrader. :(

well the 7 in stock form is particularly powerfull over the 8 is it? Though i was under the impression the 8 was a lot heavier and this would slow it down, they\'re faster than i realised.

also isn\'t the 7 a lot easier to get more power from modification-wise??

to add to this old thread, in terms of accelaration, I healthy stock RX7 will do mid 13 second quarters where a rx8 will do late 14s early 15s.
But the rx8 is a stiffer car, but is heavier then the 7, so handling is on par, I think if Mazda made a lightweight rx8 around 1200kg then it would outhandle the 7 and outperform on the track

My mum has a 250ps rx8 (import) running on superplus, so probably 240\'ish bhp in the uk cos of are crap fuel and I had a stock RX7 with a better IC running around 260\'ish first of all. The 7 out handled and out accelorated the 8 everytime - The 8 is dead from 0-5000 rpm where as the 7 has poke from 2500 - My thoughts are the power band in the RX8 doesnt stay long enough.
 
When my RX7 was mapped by carl (HR) pushing 280+rwhp I was side by side with my mates rx8 230 and I was leaving him standing everything time - both was doing 60mph ready to launch and by the time he got to 100 i was dont over 120mph and that is a big difference to me!!

It\'s unfortunate that a lot of RX-8 owners don\'t wave, but then that\'s the price of car selling success, as in the MX-5. I\'m sure their club members hate the fact that loads of people in MX-5s don\'t wave ! I prefer to let people wave at ME !! Or crank their necks so far round their heads following me. hehe

Stock the RX-7 will do the 8, I hear all of the aboves but there are two types of RX-7, the one driven fairly aggressively, and the balls-out "I\'m racing someone" type of driving. An extra 5% concentration makes the 7 so much faster, I\'ve killed DB-7s before cos they got whooped so quick they gave up. And in the second type of driving, with all that torque and roads the way they are, the superior power and weight will leave the 8 behind. Look at an elise, a fantastically handling car. Lighter than a rex, not sure about bhp per ton but even modified ones get killed by an RX-7.

And yes, I\'ve always been opinionated !! lol

And yes I own my own test track. :p (others call it the Nordschleife.... hehe).

owning both cars i think the fd defo has alot more to give than the 8. power and acceration the rx7 takes it. on braking the rx8 takes that one. MPG there realy isint much in the differnace rx8 maby a little better, handeling the rx8 FELLS like it handels better due to it being a good bit stiffer than the rx7 but the 7 seems to hold the road better even tho it feels a bit soft. on the looks front. well thats very easy the 7;)  i love them bith tho.

In any measure of real-world performance (driving on the roads in the UK) there\'s bugger all difference between a 7, 8 and a saxo.  Too low limits, too much traffic and othe rhard objects to bounce off.

Depressing really.
