Mazda design chief insists no new RX without rotary engine

Mazda’s global design chief Ikuo Maeda seems determined to convince company officials that the brand needs a new RX model. Maeda, who designed the RX-8 sports car while his father was the creator of the RX-7, says that he will never give up but still, nothing has been decided. What’s for sure is that the next-generation sports car won’t get a fuel-injected Skyactiv engine.

Maeda is convinced that the upcoming vehicle should get a rotary engine because even its name, RX, refers to ‘rotary’. For those who don’t know, the RX-8 was phased out in 2012 due to poor sales and according to Mazda CEO Masamachi Kogai, the company needs to make sure that sales of an upcoming RX model would total 100,000 units per year in order to justify a revival.

The last generation Mazda RX, the RX-8, used a 1.3-liter rotary engine that produced 250 hp and was bolted to a 6-speed manual transmission.

Regarding the performances, the RX-8 was able to hit 60 mph (96 km/h) in 7.2 seconds, while offering a top speed of 224 km/h or 139 mph. If built, the new generation is expected to be much faster than the RX-8 but also more fuel-efficient.

HIROSHIMA, Japan -- Ikuo Maeda, Mazda Motor Corp.'s global design chief, who designed the RX-8 sports car and whose father penned the RX-7, wants to resurrect the signature RX series.

"I will never give up," Maeda told A. "Inside my head, I'm always going over shapes."

Maeda emphasized that nothing has been decided, but added that it can't be done without a new rotary engine. The brand's new fuel-injected Skyactiv engines, despite being clean and sporty, just won't do, he said.

"The name is RX," Maeda said. In Mazda's nomenclature, the R refers to "rotary."

And therein lies the hitch. Mazda's engineers are still struggling to update the brand's compact and powerful, yet fuel-thirsty, rotary engine to meet today's emissions rules.

Mazda retired the RX-8 in 2012, amid slumping sales. Part of the problem is demand. Last year, CEO Masamichi Kogai said sales would have to total 100,000 units a year to justify a revival. But the engine is also a conundrum.

Mazda engineers have been trying to improve the rotary since at least 2007, when the Japanese carmaker unveiled a next-generation design at the Tokyo Motor Show. Plans to use it as the main powerplant in a vehicle are all but frozen, but research continues on the back burner.

Maeda dismissed suggestions that Mazda might jettison the rotary and mount a Skyactiv engine on the next RX.

"Skyactiv is a wonderful powertrain. So it is possible to create a sports car using that powertrain," Maeda said. "If it's Skyactiv, we would just do it in a different vehicle."

Super GT and DTM finally agree joint rules

After many months of negotiation ITR and GTA have finally reached an agreement that will see both DTM and GT500 running to a common rule book known as Class 1. This will allow cars from Super GT to race in DTM and vice versa, IMSA may also host Class 1 races.

The unified rules will see the DTM championship adopt two litre turbocharged engines as currently used in the GT500 category.

‘The top priorities: spectacular cars, a high level of safety and a cutback of operation and development costs. While silhouette and looks are similar to the ones of the latest DTM and Super-GT vehicle generations, it was agreed that turbocharged four-cylinder two-litre engines with a horsepower output of some 600bhp will power the cars from 2017′ the official announcement reads.

The two classes already share a majority of components but this final agreement on a truly common rule book is of great significance. A joint test between the two classes is expected to take place in China in 2015 or possibly in 2016, while at least one joint race with both GT500 and DTM teams taking part is expected to take place in 2017.

Much of the background and further details of the unification talks can be read in Racecar Engineering magazine below.

The prospect of DTM and Super GT cars competing in the same races has moved a step closer after more technical agreements were made to standardise the 'Class 1' regulations around the world.

Talks between organisers and the leading manufacturers from both the German and Japanese-based series' have been ongoing for some time, with chassis and areas of aero being standardised for 2014.

However, from 2017, an agreement has been reached to align the engine regulations, with two-litre, four-cylinder and turbocharged units being used in both series. Furthermore, the American IMSA racing association has announced its plans to adopt a similar format.

As such, it is hoped that DTM, Super GT and IMSA models can race together with minimum modification around the world.

“The agreement between the leading car manufacturers in Germany and Japan is an important milestone on the way to a set of joint, globally implemented Class One regulations, ” said Hans Werner Aufrecht, Chairman of ITR e.V.

“It's up to the manufacturers' to decide if they want to let their Class-1 vehicle race at Suzuka today, at the Nürburgring next week and at Daytona in a fortnight. This possibility provides totally new marketing opportunities for the manufacturers. And the joint name, 'Class One', is an important component, so to speak the cramp that is holding it all together.

“Therefore, I'm delighted that we are going to demonstrate our common ground, in Europe, Japan and the USA, with this distinctive name. All these moves will help us achieving a variety of brands never witnessed before at the highest technical level and consequently, we will provide the crowds even more fascinating motor sport.

“Isn't it a fantastic perspective that spectacular racing cars such as the DTM vehicles can be run all over the world at reasonable costs, in the future?” Masaaki Bandoh, chairman of the Japanese GTA, adds. “The meeting was very productive. We fully agreed on the concept of the common technical regulation. This agreement will create better conditions for car manufactures to participate in the other series in future.”

Mercedes, BMW and Audi currently compete in DTM, while Lexus, Honda and Nissan make up the GT500 class of Super GT

Alejandro Agag outlines plans for second Formula E season

“We hope to have three or four different makers of motors & batteries in the championship for year two." Formula E to become centre for EV development.

Formula E CEO Alejandro Agag has outlined his plans for the second season of the fully-electric FIA Formula E Championship in which he hopes to attract ‘three or four’ manufacturers – reinforcing the series as the centre of electric vehicle development and also help it gain world championship status.

Own powertrains for year two and own batteries from season three

In an interview released on the official Formula E website and social media channels (www.fiaformulae.com), the series boss talks about his plans to move away from the current one-make format and open up the regulations to allow full manufacturer involvement. Teams would then be able to develop their own powertrains for year two in 2015/16 and their own batteries from season three.

"In year two the teams will be able to build their own batteries and their own motors,” said Agag. “They could build their own whole car if they wanted. But the regulations are quite strict and they don’t allow a lot of development in aerodynamics, but they do allow development in motor and battery. I would hope that we have three or four different makers of motors and batteries in the championship for year two."

World championship status

This move would also pave the way for Formula E to make a bid for world championship status with the series requiring the involvement of four manufacturers to become a world championship under FIA rules.

Speaking earlier in the month at the opening Formula ePrix in Beijing Agag said: "There is a condition of a world championship to have a certain number of manufacturers; you cannot be a world championship as a one-make series.

"We hope to attract manufacturers, meet the conditions and hopefully the FIA will grant us world championship status."

R&D platform for EV market

Formula E is the FIA’s new global electric race series designed to appeal to a new generation of motorsport fans. It represents a vision for the future of the motor industry, serving as a framework for R&D and accelerating the general interest in these cars. By encouraging manufacturers to develop their own powertrains and batteries, organisers hope the new technology will filter into the everyday EV market, helping to make electric vehicles more desirable.
