Mazda RX7

Mazda RX7

The Mazda RX-7 was introduced in 1978 as replacement for the Savanna RX-7. The sports car joined the company’s lineup as the second vehicle to feature a Wankel rotary engine, being sold alongside the Cosmo luxury coupe. Initially powered by a 1.1-liter unit, the first-generation RX-7 received a larger, 1.3-liter engine rated at 133 horsepower later in its life. In 1983, two years before the second-gen model was introduced, a turbo version of the 1.1-liter delivered as much as 163 ponies. A redesigned model followed in 1986. The 1.1-liter engine was dropped, while the 1.3-liter version received a turbocharger of its own. Power ranged between 146 and 202 horsepower, although the latter was only offered between 1989 and 1991. 1992 marked the introduction of the third-generation model and a hefty update to the already proven 13B rotary engine. Output now began from 252 horsepower and went up to 276 in the third-generation’s final years. The RX-7 was axed in 2002, as Mazda was working on the RX-8. As we move into 2015 and toward a completely redesigned Miata MX-5 , more and more rumors about Mazda’s plans to revive the RX-7 nameplate as a successor to the RX-8 and develop a new, high-performance rotary engine are starting to surface.

According to new from Autoweek, it appears Mazda has a new RX-7 in the works with plans to power it with the famous Wankel-type rotary engine. Although it’s not fully signed off on yet, the Japanese automaker is working on the preliminary designs as you read this.

The overall design seems to hinge on one major aspect: lightweight. It is said the new RX-7 will share its platform and underpinnings with the all-new MX-5 set to debut at next year’s Chicago Auto Show. With a targeted curb weight of only 2,400 pounds, the MX-5 will be a featherweight. Comparatively, the RX-7 is said to be slightly larger, yet only weighing 2,800 pounds.

Rumors surrounding the powertrain reveal some uncertainty within Mazda’s engineering department. It’s unclear if a twin- or triple-rotor setup will be used, but according to one source, it’s likely to remain a twin-rotor setup. Displacement is said to be roughly 600cc per rotor, making the twin-rotor design a 1.2-liter engine. Targeted output levels are said to be 250 horsepower.

It appears Mazda has penciled the RX-7 for a 2015 or 2016 launch date with an expected price of around $30,000. That price lands the RX-7 smack between the more expensive Porsche Cayman and the less expensive Subaru BRZ /Scion FR-S twins.

An interesting tid-bit of notoriety: Mazda’s chief designer is Ikuo Maeda, the son of the original RX-7’s designer. Though his family blood runs through the car, he says it will not be a retro design, nor will it feature too many of Mazda’s current design language.

It’s been just a little over a month since GRID 2 hit shelves and the racing game has turned out to be a rather enjoyable diversion from our everyday lives.

It still doesn’t hold up to Gran Turismo or Forza Motorsports , but it’s the newest racing game out these days and as such, deserves our full attention. But if there’s one thing about the game that disappoints us, it’s the relative lack of some spicy aftermarket racecars ; a problem that Codemasters addressed with the release of a new DLC, called the Super Modified Pack.

As the name evidently suggests, the Super Modified Pack will feature four beastly racecars, including an 890-horsepower R32 Skyline GT-R , a 5ZIGEN Honda Civic Super Modified, and fully customized takes on the Subaru Impresa WRX STI and Mazda RX-7 .

That’s four belligerently powerful custom-tuned Japanese racecars that could be yours for $5.99 on Playstation 3 or 480 Microsoft Points (around $6) on the Xbox 360.

Sounds like a good deal to us.

We haven’t heard any details on a possible Mazda RX-7 successor for quite some time now, but new details have surfaced on the internet suggesting that such a rotary-powered successor to the RX-7 could be offered as a competitor for the next generation Nissan Z.

The new RX-7 will sit atop the current Mazda lineup and, unlike the RX-8, it will not come as a four-door coupe. It will, however, again come in the same front-engine, rear-wheel-drive layout.

Rumored to be called RX-9, the new sports car will likely be powered by a new rotary engine developed by the company and is set to be put into production within the next five years. This RX-9 will likely be initially offered in naturally aspired version, but a turbocharged version is also a possibility.

According to Mazda officials, a final decision hasn’t been made just yet because the company wants to investigate the economic situation before deciding if to offer the new sports car or not.

We’ll keep an eye out and let you know when we hear more details.

Mazda RX7

The RX-7 was one of the coolest sports cars produced by Mazda from 1978 to 2002. It was then replaced by the RX-8 - a model that did not experience the same kind of love as did the RX-7.

Skipping right past the one that may have been better left on the drawing board, Mazda has decided to bring back the RX-7 in 2017, marking 50 years since the introduction of Mazda’s first rotary-engined car, the Cosmo Sport. This same year will also mark 15 years since the RX-7 was dropped from the line.

According to Mazda Motor Corporation’s Sports Car Chief Nobuhiro Yamamoto, the new generation RX-7 will be lighter, less complex, and will deliver a greater emphasis on driver involvement. However, he also said that the new RX-7 won’t exactly follow the lead of the previous RX-7. It will be built on the same platform as the next-generation MX-5 , but will feature a a stretched wheelbase to accommodate a pair of small rear seats.

The new RX-7 will most likely be powered by a naturally-aspirated version of the new 16X rotary engine with an output of about 300 HP. A turbo version is also a possibility, but will occur later in the RX-7’s life.

As for the price tag, Mazda hopes to keep it somewhere in the same area of the Nissan 370Z, which starts off at about $33,000.

Mazda may end Wenkel engine

When the RX-7 hit near supercar status in the 1990s, the Rotary engine was a thing of beauty and Mazda had all but perfected it. The only remaining downfall was the fuel required to keep the rotors inside the engine spinning. This fuel consumption, plus a restructuring of Mazda’s U.S. market, led to the deletion of the RX-7 and its perfected rotary following the 1995 model year.

When the rotary engine made its way into the sexy, yet fairly flabby, RX-8 in 2004, the rotary enthusiast clamored over its 238 horsepower without any turbo. However, hiding in deep within the engine was its biggest sore spot, a puny 159 pound-feet of torque that sucked up a gallon of gas after only about a dozen miles. Through the RX-8’s life, Mazda refused to turbocharge the 1.3-liter rotary and the new Renesis rotary engine was effectively to blame for the RX-8’s disappearance following the 2011 model year.

This all brings us to today, as Mazda finally closes the chapter on the RX-8 by rolling the final rotary engine off of its production line and into a special edition Mazda Spirit R, which is only available in Japan. This closes one chapter in the life of the rotary engine, as Mazda has no plans to develop a replacement for the failed RX-8, despite rumors of an RX-9.

Even if the rotary is to make a comeback in the future, it will likely not come back as a gasoline engine. We would likely see it used in a gasoline/hydrogen hybrid system, as Bloomberg is reporting that Mazda is currently testing out how this Wankel works on hydrogen.

As much as we once loved the rotary engine, we think it is time to put this old dog down and let us remember the good old days of the 255-horsepower, 217 pound-feet of torque twin-boosted 1.3-liter rotary. The only way we could agree with bringing the rotary back is in a turbocharged sports car platform, like this engine is intended.

When Mazda first introduced its Wenkel engine in 1961, the automotive world was set alight it. Soon after, many manufacturers clamored to build their own. This engine was an automotive Gibraltar, no matter the challenges it faced, the Wenkel soldiered on. These challenges came from every angle from new emissions standards in 1970 to an oil crisis three years later, in addition to innumerable engineering issues. Mazda cultivated their Wenkel engine and planted it in their sporty RX-7 and it was an instant hit. Even when the RX-8 emerged as a successor to the RX-7 in 2001, the Wenkel heart beat on. Now as the RX-8’s production run is scheduled to end in 2011, a steady stream of rumors about the current Wenkel engine’s successor have flown past our desks.

First, we are going to ask all Mazda fans to take a deep breath. Okay, now that that is taken care of, we have some bad news according to Ward’s Auto Mazda is considering putting the new engine development on hold. The reason for this cutback was that at this time of economic woe, Mazda was looking for a way to reduce expenses and apparently this new engine program is very expensive.

We hope that even as the bean counters are clamoring about diminishing profit margins, Mazda continues to develop this engine. It provides the RX-8 and it’s successor with fantastic high performance and, in the era of pretty and almost all identical cars, Mazda offered a unique take on a sports car. We all hope that Mazda comes to their senses and keeps this iconic power plant.

The fact that Mazda is well into their plans to terminate the current RX-8 sports car is common knowledge at this point. However, if eliminating their only rotary-powered vehicle is in the works, why is the company still working on their Wankel engine?

There are whispers fluttering around that Mazda may be working on a new sports car model with the help of none other than Audi . Audi just released their A1 hatchback-based e-tron concept, which features a 254cc Wankel range-extender located beneath the trunk floor, so these latest rumors suggest that the two will be getting into bed together on a new rotary sports car featuring similar technology.

Mazda’s next sports car was originally thought to be the RX-9 , but recent news has gotten people thinking that Mazda may be working on a successor to the RX-7 instead. Whichever model they choose to roll with, Inside Line is reporting that Mazda’s next rotary sports car will hopefully achieve just 130 g/km of CO2 compared to the 299 g/km of the current RX-8. Other features of the new sports car may include micro-hybrid technology, auto stop/start, lightweight materials, and laser ignition - which eliminates the use of spark plugs, ultimately making it easier to seal the Wankel’s trochoidal combustion chamber for improved efficiency and reduced hydrocarbon emissions.

Now that the clock has finally run out and just hours away from the first showing of Fast Five - the fifth installment of the Fast and Furious franchise - we felt like it’s the right time to give proper respect to the characters that have made this movie franchise as fun as it has been since the first movie came out in 2001.

And if you think that we’re talking about resident leading men, Vin Diesel and Paul Walker, guess again. This list has very little to do with them, or their other co-stars for that matter, but more so about what they were driving during the first four movies. Yes, dear friends. This is a list to honor the Top 10 cars of the Fast and Furious franchise!

Do take note that we compiled this list based on our opinions so if you have any sort of reaction on the cars we chose and the number we gave them, you have the floor in the comments section to let us hear about it.
