Last Minute call for questions
Submitted by SuperUser on Wednesday, June 18, 2003 - 9:48am

RotaryNews has been invited to the Short Lead press preview and launch of the RX-8, Tomorrow (Thursday June 19th) at El Torro Marine Air Base in Irvine. The program will include an in-depth look at the return of the rotary engine as well as ample time to experience the true essence of RX-8 through an autocross and a scenic ride and drive through Southern California.
We would like to, once again, put out a call for questions about the RX-8, and more importantly the Rotary engine in general. We'll try to get these questions answered for you by the Mazda staff on hand at the event.
Click the "Add a Comment" link below to ask a question. One question per comment, please (you can post many questions, but split them up into many replys). And remember this is an "RX-8" launch, and a look at the RENESIS, so keep questions on track.

We haven't heard much about the engine management system/ECU on this car. Any details on that would be nice.

what is the reason for the discrepancy between the current EPA figure of 18/24 mpg and the earlier mazda estimate of 20/30 mpg? Is this a manifestation of a different type of testing?

If a larger displacement twin rotor or triple rotor is in the future of the RENESIS and fuel consumption is a concern, can Displacement On Demand (expected in the C6 Vette) be implemented in the rotary engine?

Is an Exhaust Gas Recirculation Valve Required on the Renesis for the RX-8 to pass emissions regulations? What kind of emission reduction systems are used on the RX-8 in general?

Thanks,
Brett

Dealers charging premiums even to "pre-sale" customers
author:
No Rotor
date:
December 31, 1969 - 4:00pm
Some of the Mazda dealers here are charging their RX-8 "pre-sale" customers a large premium on top of the MSRP - even though the pre-sale customers put down a deposit on the RX-8, sight unseen, BEFORE the MSRP was announced. I don't feel that this is a fair way to treat the most loyal Mazda customers. What is Mazda's position regarding this practice?

In the concept Mazdaspeed RX-8, will forced induction or different engine size (i.e. 90mm wide rotors) play a role in providing more power to the special edition?

RPM

Hi,

One of the reasons I am going to purchase an RX8 is due to a high RPM limit. What are the limiting factors in raising the RPM limit and redline, and why hasn't mazda trumped on this fact in advertising?

Thanks,
Joe

Another Turbocharger Question
author:
No Rotor
date:
December 31, 1969 - 4:00pm
This website previously carried a quote by a Mazda engineer at a previous press event as saying something to the tune of "the RENESIS was built for boost."

However, speculation on the boards seems to focus on wider rotors being the preferred power upgrade for the engine.

What exactly did he mean by the quote, and is it still viable?

Yet Another Turbocharger Question
author:
No Rotor

Can you speculate whether light-pressure forced induction at the lower rpm range would lead to a different driving profile, thereby leading to better fuel economy?

Will there be any factory support of any kind for race/street modification by tuners and single customers? By support I mean information made available.

1/ Early on, there was an implication that the side exhaust ports were ceramic coated inside - is this still in the design?

2/ Again early on, the RENESIS was proposed as 287hp, the unofficial Japanese limit - the 300z etc 'competition' are still there, but the '8' falls short, why?

Thanks, Ray.

One of Car & Driver's critisisms of the RX-8 was a lack of mid-range power. Is there any plan to address this issue?
