Casper Posted October 28, 2015 Report Share Posted October 28, 2015 http://insidemazda.mazdausa.com/mazda-news/mazda-new-sports-car-concept/ That thing looks awesome. Sure hope it's turbo'd and not just another N/A piece of crap. Quote Link to comment Share on other sites More sharing options...

redkow97 Posted October 28, 2015 Report Share Posted October 28, 2015 Rotary engines are cool, but didn't the RX-8 struggle to break 20 mpg with a 1.3 liter?? Until they fix that, it's not going to be viable for them to sell. Quote Link to comment Share on other sites More sharing options...

Until they fix that, it's not going to be viable for them to sell.Yes all rotary's suffer from poor MPG. Every RX7 i have owned (80,81,83,88(12a and 13b)) all got around 17mpg city or highway. And they all use oil at a rate of a qt per 1000 miles. Both these issues are why I don't see Rotary's ever being more than a niche car that falls in the gap between muscle and high end sports.

TwiztedRabbit Posted October 28, 2015 Report Share Posted October 28, 2015 I turbo'd my rx8.. prior to that it was 24ish mixed.. after a Cobb tune it was 22ish.. then the turbo and I was around 17 to 18. . But you don't buy a car like thay for gas mileage.. it was seriously the second best handling car I had ever driven. The first was a lotus exige S. Wasn't fast.. of course it wasn't meant to be.. but it handled on rails. 1 Quote Link to comment Share on other sites More sharing options...
redkow97 Posted October 28, 2015 Report Share Posted October 28, 2015 But you don't buy a car like thay for gas mileage.. . Yes, but Mazda's average MPG across their product line has to hit the government standards. Cars like this pull down their average. I have also read some troubling articles about engine wear in rotary applications. They simply 'wear out' sooner (or so goes the criticism).

TwiztedRabbit Posted October 29, 2015 Report Share Posted October 29, 2015 it is true.. the rotary does "wear" quicker.. and actually it has nothing to do with any hard parts of the motor.. in a rotary there is only like 3 main moving parts.. the average piston motor is 40 plus... butthe apex seals on the 2 rotors in an rx8... or total of 6 seals do wear out over time and need replaced..

Tomcat0403 Posted October 29, 2015 Report Share Posted October 29, 2015 According to the press release, they have addressed the reliability, emissions, and efficiency. Rumors have a few thoughts on it. Multiple small engines (4 with 2 turbos), or one engine as a power generator for a hybrid system, or multiple engines for a hybrid as well. Or just could be a solid rotary engine too. Mazda so far has done a great job of moving their concept designs to production cars. I hope they do the same with this one.

Cars like this pull down their average. I have also read some troubling articles about engine wear in rotary applications. They simply 'wear out' sooner (or so goes the criticism).Apex seals are a bastard if they're not cared for properly. If I understand the concept properly, you get carbon build-up on the seals which line the edges of the rotor lobes. Generally speaking that's all burnt-off if you rev the engine out regularly, like one would with a sport bike. However, trying to drive economically tends to let this accumulate which speeds up the apex seal degradation. The engines also heat-soak easily because there's no exhaust 'stroke' to let the cylinder cool off. Quote Link to comment Share on other sites More sharing options...
MichaelS Posted November 4, 2015 Report Share Posted November 4, 2015 Rotary engines are cool, but didn't the RX-8 struggle to break 20 mpg with a 1.3 liter?? Until they fix that, it's not going to be viable for them to sell.It was a 1.3L with 3L V6 HP of course the mileage wasn't going to be great. It wasn't much worse than those V6 cars though if you look. Mazda rotaries are high specific output engines which means no fuel economy. But there are few engines more fun to drive than a rotary. Silky smooth linear power. I still toy with the idea of picking up an 8 with the knowledge I would be rebuilding/replacing the engine fairly quickly. They are just so much fun to drive and have four doors for the other half and kid of course. Quote Link to comment Share on other sites More sharing options...
