Mazda Furai Concept

14/1/2008 - 14:38(EST) Furai is the sort of car that could only come from a company that incorporates the “Soul of a Sports Car” into everything it builds, but with an eye toward the future and the environment through the use of renewable fuels. Driving toward sustainability, Furai was initially tuned to operate on 100 percent ethanol fuel, the first time a racing three-rotor rotary engine has been fueled by ethanol. Research continues in earnest with partner BP into other renewable and future fuels, including ethanol gasoline blends like E10.

On any given weekend, there are more Mazdas and Mazda-powered cars road-raced in North America than any other brand of car. This is because every Mazda sedan, coupe and sports car really is developed with the highest possible dose of the company’s trademark Zoom-Zoom – truly the Emotion of Motion.

However, Zoom-Zoom is more than simply vehicle performance. The look and style that is Zoom-Zoom can best be seen in previous NAGARE-based efforts, including the Mazda Nagare concept that debuted at Los Angeles in 2006; Mazda Ryuga, which was first shown a year ago in Detroit; Mazda Hakaze, which appeared in Geneva last year; and Mazda Taiki, the star of the 2007 Tokyo Motor Show.

“Nagare” is how Mazda’s future models will sustain the Zoom-Zoom spirit by exhibiting their strong affinity for motion. Manufacturers commonly showcase design studies with little or no intention of actually using the theme presented. Mazda’s approach is the opposite: All of the Nagare concepts, including Furai, help evolve this evocative surface language for future use. Every vehicle Mazda sells embodies the soul of a sports car to achieve a true Zoom-Zoom dynamic character.

Nagare is how this celebration of motion will be portrayed on interior and exterior surfaces in future models. Instead of form following function, the two merge as one. Franz von Holzhausen, Mazda North American Operations’ (MNAO) Director of Design and the person who lead the team that created the Furai, explains the concept behind the concept, “We were looking for a way to bridge the gap between Mazda Motorsports and the production vehicles in our lineup.

The mindsets of road-car and racing car fans are quite different, so the purpose of Furai is to find a meeting point for these disparate interests.” He continued, “Furai achieves this by purposely blurring boundaries that have traditionally distinguished the street from the track. Historically, there has been a gap between single-purpose racecars and street-legal models — commonly called supercars — that emulate the real racers on the road.”

Track cars are, by their competitive nature, ill-suited for practical highway use, as well as generally far from road-legal. Some supercars visit the track on occasion, but they are primarily road cars not properly equipped for racing. The aim of Furai is to bridge this gap. That said, Mazda neither intends to race Furai, nor is it a supercar the company plans to build and sell in the near future. Rather, Furai is a design study that lives between those extremes. Without the restrictions imposed by serial production models, and with the freedom of an autoshow environment, Mazda is using the opportunity to evolve the company’s Nagare design theme one more step closer to reality.

Instead of mimicking racecar components and design elements in a road car – the strategy preferred by supercar manufacturers – the “Mazda way” was to begin this project with the real McCoy: a Courage C65 chassis that earned its stripes during two seasons of LMP-2 endurance racing in the American Le Mans Series (ALMS). This sports car was successfully campaigned under the MAZDASPEED Motorsports Development banner by B-K Motorsports during the 2005 and 2006 seasons. Drivers Jamie Bach, Guy Cosmo, Elliott Forbes-Robinson, and Raphael Matos piloted the car to one victory and a total of nine podium finishes in 15 ALMS events. B-K finished third in championship standings both years; Bach and Cosmo were co-Rookies of the Year in 2005.

“Anticipating future rules changes in the ALMS, we created a new closed cockpit which would be more appropriate for a future production model,” said von Holzhausen. “The major element we did not change is the 450-horsepower RENESIS-based R20B three-rotor rotary engine that provides Furai ample Zoom-Zoom. The ultimate Mazda in our minds is rotary powered; as a company, we have no intention of abandoning that valuable asset. When people think of the very best sports cars in the world, the rotary powered Mazda RX-7 is always on that list.”

The Furai concept serves as a turning point in the Nagare developmental process. While the four previous concept cars explored different ways to express Mazda’s emerging design philosophy and to explore an aesthetic, this one is all about function – every last texture and detail serves some functional purpose. In essence, the Furai creative process boiled down to guiding air over and through the body in fruitful ways. To prove that this concept goes far beyond static aerodynamic analysis, Mazda’s design, motorsports and R&D teams worked together to construct Furai as a 180-mph rolling laboratory to demonstrate its functional capabilities on demand.

“The basic proportions of contemporary race cars are every designer’s dream,” enthused von Holzhausen. “Furai is less than 40-inches high but nearly 80-inches wide.” While Furai strikes an incredibly strong presence, the real beauty of the project – and it’s most valuable asset as a real-world test-bed – is in the details that von Holzhausen and his team incorporated:

- The body surface provides ample opportunity to feature core design elements such as aggressive headlamps and Mazda’s trademark five-point grille.

- The headlamp trim pieces function as guide frames to help cancel aerodynamic lift.

- High-pressure zones just above the front wheels are relieved to serve the same end.

- The air flow package takes air moving under the front of the car and guides it inside the body to the engine-cooling radiators.

- Nagare textures incorporated in the side surfaces feed air to the rear brakes, the oil cooler and the transmission cooler.

- An under-car diffuser that begins rising aft of the cockpit helps draw the volume of air flowing through the heat exchangers and engine bay out the rear.
