WOOHOO! page 8!
The first RX-7 was ~2300lbs. The current fully loaded MX-5 weighs 2500 lbs
And I don't think a pure sports car is out of the question. The "barren" MX-5 when it first came out in late 80s didn't have all the gadgets the competitors had or the horsepower, but it was a smash. The first RX-7 was the same way. It just has to be enjoyable and priced right.
You are just not going to see a 2600 lbs RX-anything from Mazda. The lightest RX-7 ever made was about 2600 lbs and that was in the mid-80's. With all the new safety features that are required today (and even more in 2-3 years) and creature comforts that the general public (and their collective buying power) demands you just aren't going to see it.

Others rely on more HP, bigger displacement and more structure for better performance and higher stiffness.... increasing weight, and diminishing the performance of all that fancy engineering and more power.
High strength steel, alumiinum, and plastics combined with single-minded engineering dedication can reduce weight if applied correctly, of course at a cost in $$, but it's plain to see that Mazda is feverishly working in that direction.

Exactly what is the weight of the new Mazda 6? And how much lighter is it than the old one? Does anyone know at this point?
I'll bet the new car will be marginally lighter, around 60 lbs or so. Mazda can then say bigger yet lighter.

Its was only last month that an Australian Dealers Service guys where I once worked said that the RENESIS and Rotary is dead, because all of the "so called" reliability issues with the RENESIS...that is it. This was from a Service Managers meeting hosted by Mazda Australia which is Owned by Mazda Japan.. Their words that Mazda was pulling the plug not mine.
Whatever Mazda does in the near future any so called "larger" engine will have to have a lot more than "extra HP" going for it, and then there is the production and tooling cost for another so called "clean sheet design".
It is a huge financial gamble and I am just not sure if it will pay.
Its is the price of crude which also concerns me.
Interesting times ahead...the rumored new RX-8 next year IMO will have little change to the Engina...

I think it's the price of crude that Mazda is counting on to ensure the rotary's success. As the only engine capable of running on Hydrogen and gasoline they are working to develop a platform that will make them the front runner in a multi-fuel economey.

i pwn therefore i am
How do you figure? You haven't seen anything yet. The RX-7 was always as fast as it's competition despite far less power. An Evo isn't all that. At well over 3000 lbs (3200 lbs???), even a 2800 lb competitor wouldn't need nearly the power level. Then consider that it probably would have comparable power and I just don't see what the issue would be. It might not win off the line but that's the real advantage of all wheel drive. It wouldn't take very long to catch up.

The Hydro Hybrid RENESIS promoted by Mazda Japan (RX-8) at the moment has around 50% less (HP) power than when running on everyday gas and a Hydro Tank Mileage Range of about 100 Ks or 60 Miles.!
I would think that at least 50-60% of all vehicle manufacturers would have to have hydro fueled passengers cars in the pipeline for any viable investment in Hydro Stations.....
Just to add one thing....I am as keen as most for Mazda to continue with their Rotary as there is nothing as unique as a rotary powered car.

That POS does not share the "design language" from any other Mazda concept. You photoshopped it, didn't you?

I'm looking forward to this release. I'm doing a couple mind experiments trying to picture how the 'long' stroke will increase its dimensions and in what area. First guess is same width with an overall larger rotor, longer combustion face, wider housings for the slightly larger path it will be riding which eguals a taller engine.
I'm thinking this will have more travel time between next combustion cycles which will lead to more energy from the first combustion to transfer (aka more torque), but this will most likely lead to a lower redline. Figure the disp up around 16% i'd guess the redline to drop to about 7500.
But who knows, i could be an idiot.
