"We will never give up," says Mitsuo Hitomi, general manager of Mazda's powertrain division, referring to the automaker's long-running investment into the rotary engine. This vote of confidence in Felix Wankel's replacement for displacement will surely come as welcome news to rotor-heads the world over, but that doesn't mean there aren't problems in World of Wankel.

Apparently, the so-called 16X engine, which is the latest take on the pony-keg-sized engine that spins into the stratosphere, is failing to meet emissions requirements set by the engineering team at Mazda, despite the fact that it is 30 percent more fuel efficient than the previous Renesis rotary. Impressively, Hitomi stated that the 1.6-liter 16X is slightly more fuel efficient than the automaker's standard 2.0-liter gas engine.

It would seem that the rotary's well-known thirst for fuel has at least partly been quenched, but until the 16X is tuned to hit its emissions targets we can expect it to stay in the engineering department and off the showroom floor. So, when might we see a new rotary-powered machine from Mazda? "Maybe within two years we can tell you when we will introduce it to the market," responds Hitomi.

Now, let the debate continue as to what kind of body and platform that engine will be featured in...

Mazda RX-8 to exit U.S. market after 2011 model year?

According to "a well placed source at Mazda's North American Operations," Motor Trend is reporting that the aging RX-8 is set to exit stage left here in the States after the 2011 model year. As it is, the rotary-powered sportscar is slated to see the European guillotine at the same time due to its inability to meet Euro V emissions standards.

There are a number of issues that all manufacturers that have chosen to borrow the rotary engine design from Felix Wankel have had to deal with, not the least of which have been poor fuel efficiency, comparatively high exhaust emissions and excessive oil consumption. It seems that these same long-running plagues may kill off yet another fun-to-drive rotary-powered model from Mazda.

Mazda has not made any formal announcements as to the death of the RX-8 or the rebirth of the perennially rumored RX-7 revival. That said, we'd be more than a little shocked if Mazda didn't renew its commitment to the high-revving, barrel-shaped rotary engine wrapped up in some sort of innovative package within the next few model years. We'll see.

Report: Next Mazda RX-7 in development, but don't hold your breath

It's the rumor that just refuses to die. We're not sure if that means there's a lot of truth behind it or it's just wishful thinking, but once again we're hearing that Mazda is hard at work on a new RX-7 sportscar. And while you might think such a vehicle would be as easy as adding a turbocharger to the existing Renesis-powered RX-8 and jettisoning the back seat (or pulling a Kabura with the MX-5's platform), Mazda apparently has much more grandiose intentions for its next range-topping sportscar.

According to Motor Trend, Mazda's oft-talked-about 16X rotary engine is now capable of running on either gasoline or diesel with nary a difference in performance. We have to wonder about the accuracy of such claims, but if true, perhaps running on diesel or biofuels would give Mazda the eco-cred it's aiming for - specifically boosted fuel economy and lower CO2 output. In any case, MT says that Mazda is aiming for something north of 300 horsepower with improved fuel consumption, emissions and oil intake over the current Renesis.

As ever, we're taking a wait-and-see approach to these continuing rumors. As much as we'd love to see a new RX on the scene, we're beginning to wonder if it's ever going to happen. In the meantime, enjoy the photo gallery of the too-awesome-for-words Mazda Furai concept.

Mazda RX-8 to die as RX-7 resurfaces for 2012?

Jeremy Korzeniewski — Sat, 26 Dec 2009 12:45:00 EST

Filed under: Coupe, Performance, Mazda, Rumormill

The rumormill just can't stop churning out stories of an impending Mazda RX-7 revival. We've been hearing that we should expect the rotary-powered sports car any day now... for the last few years. It's still yet to show its smiling face. Still, here we are with another report indicating that the next RX-7 is just around the corner, this time as a 2011 or 2012 model.

Inside Line reports that the birth of the two-seat Mazda RX-7 will mean the death of the current four-door, four-seat RX-8 that's been in circulation since 2004. Furthermore, the gang in Santa Monica says that next-gen rotary sportscar may not up the performance ante of either the last twin-turbo RX-7 or even the current RX-8's 1.3-liter 232-horsepower Renesis engine. This, despite earlier rumors that the latest 1.6-liter 16X powerplant was kicking out as much as 350 horses while still achieving superior fuel economy over its forebears.

Mazda could instead return to the ethos of the first RX-7 from 1979, fielding a lightweight two-seater powered by a new version of the Wankel producing somewhere between 200 and 250 horsepower. If true, we can expect the next RX-7 to cost somewhere around $25,000 and be positioned against cars like the Hyundai Genesis Coupe and the upcoming RWD Toyota/Subaru.

REPORT: Mazda's next-generation rotary needs more work

Though the rotary engine certainly has its fair share of detractors, many who find themselves behind the wheel of a Wankel-powered machine from Mazda fall in love with the engine's zippy and rev-happy characteristics... including this particular blogger, who purchased a new RX-8 back in 2004. Regardless, nobody can deny that the rotary has always been a thirsty little bugger, especially when compared to powerplants with similarly rated displacements.

We've been hearing for the last few years - and seemingly every other time a new rendition of the Wankel engine came to market - that the next version of Mazda's rotary would address complaints about its high fuel consumption and emissions. Perhaps the early projections about the so-called 16X engine were a wee bit premature. According to Seita Kanai, head of R&D at Mazda:

The 16X demonstrated the possibility, but that performance is not good enough. We are doing R&D which will incorporate more new technology... The 16X is more a profile of a rotary still in our concept stage. It needs more evolution.

That really doesn't sound all that confidence inspiring to us. At this point, only time will tell if the 16X will actually be ready for prime time when the long-rumored next-gen rotary-powered car from Mazda hits the scene in 2012 or so.

Rumormill: Mazda RX-7 concept headed to Tokyo Motor Show?

Ever since Mazda revived its Wankel rotary program in 2004 with the RX-8, the internet rumormill has constantly been abuzz with reports of a proper two-door RX-7 variant. The latest such rumor comes by way of Japanese magazine Best Car (via JDM-centric website 7Tune.com), which indicates the new sportscar has a 55% chance of making an appearance at the upcoming Tokyo Motor Show in October.

We understand that Mazda's continual development of its rotary engine technology is likely to bring a displacement boost from 1.3- to 1.6-liters for the next RX model - whatever and whenever that may be - along with the seemingly contradictory qualities of more power, cleaner emissions and lower fuel consumption.

Naturally, Best Car provides a rendering of the supposed RX-7 to go along with the speculation of an October debut. Drawing inspiration from the expressive styling language from Mazda's recent concept cars along with a hearty dose of the happy-go-lucky expression of the current Mazda3. We'll see if there's any truth to this report in, oh, about three months.

Rumormill: Mazda RX-7 still under development, next RX-8 to be called RX-9

Damon Lavrinc — Thu, 12 Feb 2009 20:36:00 EST

Filed under: Coupe, Japan, Tokyo Motor Show, Mazda, Rumormill

The recent news out of Japan hasn't been good for fans of front-engine, rear-wheel-drive two-doors. First came word that Subaru and Toyota were postponing the launch of their boxer-powered RWD coupe, then the S2000 is killed off and finally reports suggest that Nissan has cancelled its Silvia successor. Thankfully, all is not lost. InsideLine is reporting that Mazda is hard at work on another version of the RX-7 and development is underway on the next RX-8, supposedly - and predictably - dubbed the RX-9.

According to IL's (traditionally) unnamed sources, Mazda is working on a 16X twin-rotor Wankel (two rotors, each displacing 800cc), boosting displacement of the current 13B by 300cc and putting out upwards of 270 hp in naturally aspirated guise. Mazda's aim for its next generation of rotary engines is to dramatically reduce emissions and boost fuel economy to the tune of 20%.

Mazda will likely use the same engine to motivate the RX-7, but in addition to offering a traditional manual gearbox, Mazda is developing a dual-clutch transmission with a twist: the DCT will allow drivers to set the exact points where the clutch packs engage for maximum performance on the track.

The RX-7's circuit-friendly cred is enhanced by the report that Mazda engineers are struggling to keep the coupe's curb weight in check. An all-new chassis is being developed that will supposedly eliminate around 220 pounds, bringing the RX-7's weight down to approximately 2,640 pounds.

We're keeping our fingers crossed that both the RX-7 and RX-9 will make an appearance during this year's show season, although the way things are going, we don't expect to see either at this year's Tokyo Motor Show.

Wrenching LeMons: Late nights and flying sparks

Damon Lavrinc — Wed, 19 Sep 2007 18:28:00 EST

Filed under: Motorsports, Etc.

As our October 20th deadline for destruction grows near, we've been making some significant progress on Project LeMons. After the interior was stripped and the hatch removed, Casey and Brad got to fabricating the roll cage out of pilfered pieces lying around the shop. We've got a full hoop mated to a couple of 50ish-degree pipes that tie into the custom rear strut tower brace. Last night, the harness bar was welded in place, along with the plate to mount the door bar to the floor, and although there is a seat sitting in the appropriate place, it's not mounted to anything yet.

Next up: we've got to weld the door bar in (and possibly add another one above it), get the seat positioned and secured, replace the brakes and water pump, and try to find a driveshaft. The good news: while yours truly was running ragged around Frank-town last week, the Modacar crew hooked up a battery and turned the beast over, and according to Brad, "it runs like a champ!" Can we get a "hooraa!"

Oh, and we cut a few holes into the hood to allow some airflow and plan on ditching the front and rear bumpers, and fitting some custom tubing in their place.

Our friend from Shutterflick snapped off some photos for your perusal; you can check them out below.
