A normal day, a normal weekend

It was a normal weekend from Barcelona, ​​another normal day at home, a typical day in the administration of Rotay Power Crew, is a laborious task for one person, involves a tough management and dedication, it is normal that sometimes remain me pending things.

I was just reviewing notifications on social networks, while searching information for a new article for the blog and was there, a notification (another) pending read.

All right! It seemed a message and this time was no spam, great. It was a message of Adam, he wanted to show a video of the images they recorded in normal weekend of racing at Phillip Island.

The video speaks for itself, Mazda RX7 of all generations, different Rx8 that would give anyone a heart attack only with their sound and a lot of cars running background rotating track circuit, Phillip Island is that on a normal day. Here in Barcelona, ​​you usually look surprised if you see a rotary drive down the street, as scarce as unicorns.

So I want to thank Adam their contribution and all people fond of video, photography, fans and car owners who contact me providing all kinds of material for Rotary Power Crew. I leave the video, enjoy it to the highest quality with headphones, the sound worth it.

Meeting the RX Vision


Today we get to see the next chapter in Mazda’s love affair with the rotary engine: it’s called the RX-Vision, revealed today at the Tokyo Motor Show.

A time to rejoice then, that there’s still room for freedom of expression in an increasingly homogenised car industry. The RX-Vision is a two-door, two-seater sports coupe that previews a successor to the RX-8 – and will bring back the RX-7 name for the fourth time in Mazda’s history. If it can overcome the financial and technical hurdles to actually make it to the showroom, that is.

“Will it be called RX-9? Well, all previous RX-7s have been two or 2+2 seaters and the RX-8 was a four-seater, so what would that make RX-9? A six-seater? This concept is a two-seater so you can imagine which number fits best,” Kiyoshi Fujiwara, Mazda’s head of R&D told us at the Tokyo show.

The RX family’s front-engine, rear-wheel drive formula is untinkered with, but what’s under the hood is box fresh. It’s a “next generation” rotary engine christened SKYACTIV-R that Mazda says addresses the three perennial stumbling blocks for Wankel engines: economy, emissions and reliability.

Fujiwara wouldn’t be drawn on specific numbers, but he did say this: “If we are able to mass produce this car, then maybe a Porsche Cayman is the right comparison, but like the MX-5 we want to make it lighter.”

Now we’re getting somewhere. A standard Cayman has 271bhp, a Cayman S 321bhp, so let’s split the difference and assume Mazda can extract 300bhp from its new rotary. It would need to weigh in the region of 1,300kg to undercut the Cayman by 100kg – enough for 0-62mph around the five-second mark.

To reach those heights turbocharging seems likely. “I can’t go into details, but we believe turbo is one of the options we can look at for rotary,” said Fujiwara. “At this moment we’re not working on a rotary hybrid system,” he added. And what of CO2 and NOx emissions? Fujiwara claims “it will be at the same level for an equivalent standard petrol engine.”

At 4389mm long, 1925mm wide and 1160mm high it’s slightly shorter, a fair bit wider and a whole lot lower than the RX-8, although the 2700mm wheelbase is identical. The concept wears 20-inch rims wrapped in 245-section tyres at the front and 285 at the rear.


The styling conforms neatly with the minimalist Kodo design language already deployed across the entire Mazda range – further hinting at its production readiness. But whereas the MX-5 is all built around a compact and lightweight philosophy, the RX-Vision gets to stretch its legs a bit. As you’ll no doubt spot, it’s absolutely gorgeous.

Clearly, Mazda doesn’t do things like everyone else. It’s shunned turbochargers in its small SKYACTIV petrol engines, kept the MX-5 alive and kicking despite shrinking roadster sales globally and has demonstrated an unwavering commitment to the rotary engine since the early 60s – the only major car maker ever to do so. And just when you thought a rotary engine couldn’t possibly meet modern emissions regulations, it’s gone and pushed the boundaries again.

And in a moment of impressive product planning symmetry, it’s been 12 years since the RX-8 arrived, the exact same gap between the third-generation RX-7 and the RX-8. Clearly the time is ripe for Mazda’s next halo model. It also attached this slogan to the teaser video: “This model represents our dream. But we don’t want it to stay a dream forever.” Sounds pretty unequivocal to us.

Big question is, when exactly will the new RX-7 arrive? Launching in 2017, to coincide with the 50th anniversary of the first rotary-engined Mazda, is something Fujiwara “would dearly like to do” if he could, but it sounds a little soon. Although he “already has a solution for technical issues,” the more pressing issue is making the company more financially robust, and less Japan-centric. Only then can it cut loose and do what we’re all screaming for – turning the RX-Vision into a reality.

Mazda keeping rotary fans on ice

Mazda’s new chairman has provided the strongest hint yet that a rear-wheel drive rotary-powered sports car will once again grace its showrooms.
Speaking to Australian journalists in Hiroshima, Seita Kanai would not rule out the development of a second model based on a version of the new rear-drive platform that will underpin next year’s fourth-generation MX-5.
Mazda revealed the rear-drive SKYACTIV chassis architecture that will underpin the new MX-5, which will be revealed this year before going on sale globally in 2015, and an all-new convertible from Fiat.
At the time, the company’s global sales and marketing chief Masahiro Moro confirmed the platform was scalable and could therefore form the basis of other models, but refused to elaborate.
When asked if the new MX-5 platform could be used for another sports car such as a born-again rotary coupe, Kanai-san said with a smile: “Too much good question. I cannot answer.”
Interestingly, the only other question for which he provided the same answer in a wide-ranging interview concerned the ‘CX-3’, which is widely expected to be revealed later this year.
While the all-new Mazda2-based compact SUV is tipped to become Mazda’s seventh global model in 2015, speculation of a belated replacement for the long-lamented RX-7 has bubbled since Mazda discontinued its four-door RX-8 ‘coupe’ (pictured) in 2012, leaving Mazda without a rotary model.
Mazda has restated its commitment to the rotary numerous times, most recently via its newly appointed corporate communications chief Hidetoshi Kudo, who was previously Mazda’s product strategy chief and this week said: “We have no intention of stopping development of the rotary engine. It’s part of our ‘challenging convention’ spirit’.”
Mazda has also revealed a new-generation larger-capacity twin-rotor engine dubbed the 16X and said it will apply its SKYACTIV engine technologies to the reciprocating Wankel engine in order to overcome fuel and oil consumption issues that plagued the RX-8.
However, it remains unclear whether the rotary engine has a future at Mazda beyond its application as a scaled-down 330cc single-rotor range-extending engine/generator, as seen in the Mazda2 plug-in hybrid test prototype. But that hasn’t stopped widespread reports that Mazda will use the occasion of the rotary engine’s 50th anniversary in 2017 or the RX-7’s 40th birthday in 2018 (two years before Mazda’s centenary in 2020) to introduce an all-new rotary sports car, possible badged as the RX-9.
The Japanese brand says that as the producer of more rotary-powered models than any other car-maker it has a duty to continue its custodianship.
The first rotary engine was patented in 1929 by German engineer Felix Wankel, who licensed the technology to Mazda and German car-maker NSU, which evolved into the Audi brand after it produced the rotary-powered Ro80 in 1977.
Mazda built almost 812,000 two-seat RX-7 coupes between 1978 and 2002, and more than 192,000 four-seat RX-8s between 2003 and 2012, notching up more than a million rotary sports car sales since the Cosmo Sport rotary in 1967.
Mazda refuses to reveal how many engineers are currently officially devoted to rotary vehicle development, but points out that such important projects can come together quickly with enough enthusiasm, as evidenced by the original MX-5.
Mazda’s first roadster began as an “offline” project without official permission at the hands of a small number of Mazda enthusiasts, ironically at a time when the US success of the RX-7 negated the need for a second performance model.
A full-size clay model was developed from sketches in 1984, before a running prototype codenamed P729 was shown to 350 people at California’s Anaheim stadium in 1986.
“Eighty per cent of them said they would purchase the car if it cost $US17,000 as an average and with that information in hand we went to top management and the CEO told us to immediately build it,” says Shunji Tanaka, the chief designer of the NA MX-5.
“Suddenly the priority of the product became very high and within 15 months we brought it from prototype to job one with no change to design.”
For now though, Mazda says its current priority is the new MX-5, which celebrates its 25th anniversary this year.
“No, not at this moment,” said Mazda’s global sales and marketing chief Masahiro Moro, when asked about the prospect of a second rear-wheel drive sports car.
“Our mission is to make the MX-5 very successful. After that we move towards the next stage but our current mission is purely how can we make the MX-5 successful.”

Mazda Eunos Cosmo

The Eunos Cosmo is the pinnacle of rotary technology. Mazda simply did not compromise when designing what is arguably the ultimate vehicle in their automotive history. With it’s legendary rotary engine now available in 3 rotor form, the Cosmo was designed with the sporting affluent in mind, & to exceed all their expectations.

Jaguar, BMW & Mercedes luxury coupe’s were the targets Mazda aimed for, & when released onto the Japanese market in 1990 the Cosmo easily outshined the best of them with styling years ahead of it’s time. Introduced aswell was Japan’s first factory fitted G.P.S.S (Global. Positioning. Satellite. System) & touch screen system to take the Cosmo well into the next decade. Motoring journalist throughout the world made pilgrimage to Mazda,s Hiroshima headquarters to test drive Japan’s most technically advanced car. Reports such as “Rotary masterpiece” & “Japanese Jaguar” were features of prominent motor magazines from the U.S & Europe.

Manufactured between 1990 & 1996, Mazda kept production at a selected rate to ensure the maximum build quality possible. A consequence of this being the price premium buyers were forced to pay in order to enjoy it’s prestigious status. Mazda Australia investigated the sale of the Cosmo back in 1990 but were deterred by the expected $110,000 price tag to have it on Australian roads, aswell as being a couple of years behind in setting up the luxury Eunos sales channel.

In order to advance on the level of motoring the Cosmo is reputed for, Mazda surveyed buyers of the previous HB series Cosmo coupe (82-88) to find the luxury interior with it’s “advanced” features was an important factor in deciding to purchase the car. The “wrap around” cockpit of the JC Cosmo has been designed to cater for the personalised tastes of such buyers with the quality of the optional leather interior matching the best of many a European marque. The top level “Type-E.CCS” model with it’s touchscreen “Car Control System” handles most of the cars system’s at the touch of a finger & real “Milano” wood graces the dash to add the required prestige.

20B-REW 3Rotors Engine

20B-REW 3Rotors Engine

Mazda’s famous rotary engine has been steadily improving since their original L10 Cosmo from the 60’s. The Cosmo’s heart has been enlarged from the well known 2 rotor 13B to the 3 rotor 20B which shines as the ultimate example of a production rotary engine. It’s the worlds first series production engine employing a twin “sequential” turbo system & has resulted in an amazing level of torque from it’s 1962 cc capacity. With over 390 nm available from as little as 2200 rpm, the 402 nm peak at 3000 rpm drops by less than 10% at the 7000 rpm Redline. Mazda’s rated power of 206 kW is at the Japanese power limit, but careful questioning of officials found the real figure to be around the 220 kW mark. How does it work ? The primary turbocharger receives the full benefits of exhaust gas from all the rotors to spool faster, thus improving low speed torque & eliminating lag. The 2nd turbo whilst spinning is still yet to provide any boost. At a pre-determined speed the 2nd turbo comes “on-line” to add full boost. The result is effortless performance combined with the rotaries natural smoothness & flexibility.

The triple mode automatic transmission is superbly matched to it’s luxury coupe image. The press of a button gives a choice between “normal” & “power” mode, the latter increases responsiveness to the accelerator position aswell as holding the gear longer before the next upchange. The “hold” mode gives manual control. A great feature for demanding driving aswell as the added safety benefit of 2nd gear take offs giving greater traction during slippery conditions.

With a clean slate to start from. Mazda engineers have designed a truly remarkable chassis to provide the form & function demanded of this high performance coupe. Safety has been well catered for with the use of carefully designed crumple zones & safety impact bumper bars front & rear. ABS is standard for all 20B versions a capable of returning the 1500+ kg of the Cosmo to a full stop in amazingly short distances. Suspension is fully independent with the “E-type” rear incorporating twin dampers. Progressively sprung to give sure footed handling & control. Stiffer spring rates & dampers for the “type-S” show it’s performance advantage over “type-E” versions.

Mazda updated the Cosmo for the 93 model with the addition & omission of a new version to reflect tastes of the series I buyers. The series I thus runs from 1990-1992 with the series II from 1993-1995. Changes to the exterior were minimal but trim levels did get altered.
