Who Knew? – Mazda Rotary Engine Still Alive

Mazda rotary engine technology lives on. Since the last rotary powered RX-8 sports car was retired in 2012 there has been much speculation on when we would see another Mazda rotary engine in production.

In 2017 Mazda celebrated the 50 year anniversary of the first rotary powered production vehicle. Even though rotary power had been benched, research and development has continued to refine the technology and adapt it to other fuel sources including diesel and hydrogen.

Kenichi Yamamoto who led the effort to mass produce the rotary engine passed away in December 2017 at age 95. Known as the architect of the Mazda rotary he directed development in the 1960’s and later became Mazda’s president in 1985 and chairman in 1987. In addition to his many accomplishments with rotary while president he paved the way for production of the Miata.

A teaser in 2015 at the Tokyo Motor show of a RX-9 concept car fitted with a Skyactiv-R rotary engine has kept hope alive for fans that another rotary sports car may be on the way. There is confirmation that rotary research continues and rumors from development managers that a next generation rotary engine sports car is in the pipeline.

Who Knew? Mazda Keeping History Ready to Drive

Who knew that underneath Mazda’s Research and Development facility in Irvine, California there is a basement full of historic Mazda vehicles. Not too surprising that Mazda would preserve a museum of heritage cars, but these vehicles are not there just for display, they are maintained to be ready to drive.

For those who enjoy tinkering on classic vehicles, to be in charge of keeping Mazda’s Heritage Collection of about 80 cars road ready would be a dream come true. Mazda Motorsports Engineer Randy Miller has this dream job of curator, restoration artist, race car engineer, fabricator and maintenance mechanic.

Randy’s dad helped him work on his own cars that led to an automotive degree. After some time at Mazda’s service shop he became a R&D engineering technician that led to a full-time position with the Heritage Collection.

Who Knew? Mazda Design and Bread Making – Similar Hand Crafting

Mazda continues to push to make its vehicles stand out from the crowd. Allowing its designers to have more freedom than most manufacturers to inject life and soul into the vehicles they are creating. It is a philosophy Mazda calls KODO – soul of motion.

At Mazda’s Master Craft event in Los Angeles the similarities between Mazda design clay modelers and artisan bread makers became apparent. Unlike other car companies who only use computers in new vehicle design, Mazda’s modeled-by-hand design using clay is present in every step of the design process. Using clay models rather than computers and mathematics can make a car’s crisp exterior lines seemingly disappear, evoking emotion through its more fluid form instead of being “boxy and boring.” Artisan bakers agreed that “Like clay modeling, we shape every loaf by hand. It’s all about scale, shape and creating an out-of-this-world product.”

Mazda uses more clay than any other manufacturer in its KODO design process. KODO design is about “creating cars that embody the dynamic beauty of life – cars that visually suggest different expressions of this energy”. While the initial digital design model visualizes the fine details and specific materials of a vehicle, it is the sculpting from clay that brings it to life, something Mazda believes is impossible to replicate digitally.

Who Knew? – Mazda Instills KODO in New Concept Cars

Mazda recently unveiled two concept models, the Mazda KAI CONCEPT and the Mazda VISION COUPE at the 45th Tokyo Motor Show. The new models are a continuance of Mazda’s new design philosophy: KODO – Soul of Motion. A philosophy to use design to breathe life to a car and make it more than a means of transportation or a mass of metal.

Mazda intends to go forward into future model designs with goal of bringing energy and rhythm to create even more elegant cars. The Mazda KAI CONCEPT compact hatchback features the next-generation SKYACTIV-X gasoline engine and advanced SKYACTIV-Vehicle Architecture. It boasts refinements in all areas of dynamic performance to produce a dramatically quieter, more comfortable ride and an enhanced performance feel. The KODO design features muscular, solid proportions and the use of reflections over the body sides to bring it to life.

Who Knew? – Mazda’s Sustainable Earth by 2030

Mazda has a goal to create a future in which people and cars coexist with the Earth. This long-term plan for technology development, which they are calling Sustainable Zoom-Zoom 2030, includes innovative technologies and a partnership with Toyota.

The vision includes perfecting the internal combustion engine, reducing carbon dioxide emissions, and introducing electrification technologies.

Mazda has reinvented the gasoline engine, being the first to successfully use compression ignition and a supercharger to increase engine efficiency by 30 percent and torque by 10 to 30 percent. This technology allows this gasoline engine to outperform diesel fuel efficiency while also lowering emissions.

Who Knew? – Mazda Rotary Engine Lives On

Who knew? – It’s the 50th anniversary of the Mazda rotary engine. Mazda is the only carmaker to mass-produce and bring to market the rotary engine. Had it not been for the uniqueness of the rotary engine, there would probably be no Mazda. In the 1950s and 1960s, Japan’s Ministry of International Trade and Industry wanted to streamline the number of carmakers. Thinking that bigger manufacturers would be more likely to compete with US and European heavyweights, Mazda was afraid they would be vulnerable to a forced merger.

But a carmaker pioneering a bold new type of engine would be much more likely to maintain its independence. The unconventional rotary engine appealed to fans and offered a distinct reason to buy a Mazda. The successful introduction of the rotary-powered Cosmo Sport in 1967 launched Mazda as an influential carmaker.

Who Knew? – Mazda Engine Cuts Fuel Use by a Third

Mazda will soon introduce a new engine that uses technology that will increase fuel economy by 30 percent. The technology called homogeneous charge compression ignition has been studied by many manufacturers, but Mazda will be the first to overcome the quirks and put it into production.

The SkyActiv-G direct injection gasoline engine uses compression ignition to boast efficiency combining the advantages of gasoline and diesel technologies. Most production gas engines have a compression ratio of 10:1 to 12:1. This engine has an exceptionally high 14:1 ratio, allowing it to squeeze more energy from every drop of fuel.
