New RX-7 ???

There might already be another thread on this somewhere but...meh
Apparently Mazda have a new RX-7  on the drawing board if not a well advanced prototype somewhere.
A site claimed that mazda is going to use the RX-8 floor pan, although the new RX-7 body will be much shorter and wider than the RX-8. As for the engine, it will apparently have the new renesis with an extra rotar, making it a 1.6lt engine, instead of the 1.3 it is now and should develop between 300 - 320 hp.
Exciting times ahead with the new RX-7 + Supra + R35 Skyline(if it isn't out in Japan already)/350z

Mazda are going back to their roots with this car. It won't be the twin sequential turbocharged monstercar its brother was but will be much more similar to the s1-3 models.
They are aiming for an extremely low weight of 1 tonne and the chassis is based off of the rx8 chassis.
The engine will be a larger displacement renesis twin rotor unit, i'm not 100% sure on the maths but it should be about 1.5ltre (by widening the rotors another 10 mm as mazda have done from the 12a to the 13b)
It will not be released as a forced induction model but rather naturally aspirated. 300hp is easily obtainable but it will definatly be pushing more.

I think we can bet on that it won't have pop up head lights 
When I was in Japan in 2003, I was in a homestay and the father in the family was like the CEO of Continental brakes in Japan, and he hinted then that Mazda were thinking of bringing back the 7.
Should be a very interesting car when it makes its debut.

In what way? RX8 and 350Z are awesome. Sure not as outright fast as their forefathers, but good fun cars.
|
ya agree with what u say. but by the looks of things ppl would be expecting SOO MUCH from the new rx7 that itll be dissapointing. ppl are expecting it to be better than current FD and i think they will be dissapointed.
its not that mazda is gonna make a shit car, its ppl are over expecting

I doubt that they'll be dissapointed because the car will be better than the fd in everyway. The chassis is going to be much stiffer, its lighter weight with more power. Much more tuning potential due to the larger engine. In reality it doesnt have that much to live up to. Sure the fd was a great car but its very dated by todays standards.

Considering the RX8 is as refined as it is, yet when Top Gear tested it around their track it level pegged a BMW M3 for times, I don't think people will be dissatisfied when Mazda applies the same approach, yet makes it faster and more focused, I wouldn't be complaining!

one thing about the rx8 a lot of people dont really know. The ecu tuning done by mazda is VERY very sloppy. Some yanks on the rx8club forum have put on a piggy back ecu, exhaust and have been able to bring out over 300hp reliably. So a 1.6 could theoretically be able to produce 346hp... NA

This would be very conservative tuning to help the very dirty rotary pass emissions standards

actualy the renesis has some funky port setup so that theres no overlap as both intake and exhaust ports are on the same face. Also some thing that runs unburnt fuel back into the intake port so emmissions shouldnt really be that much of a hassle

The Renesis is a markedly improved engine from an emissions standpoint, but they still aren't super clean Aside from the hydrogen powered versions of course

i highly doubt a rotor will ever be "super clean" because piston engines simply have had so much research put behind them and were forced to become clean during the opec oil chrisis and what ensued.
But who cares about crap like that? (no offence to hippys)

|
The website I got the info off said it would be either 1.5lt or 1.6lt. So as its a triple rotar engine, maybe the rotars will be thinner than they are now... making... i guess a 16b instead of another 20b.

in the current issue of speed magazine (the one with the 13b ae86), it ssays very breifly at the start that mazda have given it the go ahead. it also says that the engine will almost definately be a two rotor based on the renesis. capacity will be increased with wider rotors to about 1.6l

theres a crapload of conecept picks but none are official.
Personally, i'd just like to see it look like the mx5 coupe but with rx7 styling cues (pop up lights, large round rear window, and more aggressive styling all round)

In fact, I think you should ALL go out and buy the latest issue of speed magazine, and turn to pages 124 & 125

Mazda said that there are a couple of ways to increase the power in the rotor one is forced induction which mazda said they wont use the other is to add an extra rotor but mazda said that would add undesirable weight to the car the last is to make the rotors bigger which is the preferred option so id say we will be looking at a 1.6 ltr version of the renisys motor.
