Since Nissan split with the DeltaWing program in 2013, Don Panoz and his team have (understandably) accused Nissan of copying the racecar’s unique design for use on the Nissan ZEOD RC racecar and the 2013 Nissan BladeGlider Concept. Since it looks like the hopes of getting Nissan to cease and desist such activities aren’t going as planned, DeltaWing, instead, will try to beat the Japanese automaker at its own game.

DeltaWing Technology Group, parent company behind the DeltaWing team, announced today a plan to build a street car that uses the same narrow-front-track design as the racecar. The company is looking at both two- and four-passenger versions, which will initially be powered by a 138-horsepower four-cylinder engine. DeltaWing is also keeping other propulsion systems in mind, including electric, hybrid, hydrogen fuel cell and any transverse internal combustion engine including gasoline, diesel and compressed natural gas (CNG).

There is no indication yet as to when such a car could become reality, but with as many problems (and general lack of success) as the DeltaWing had on the track in its three years of racing, there will be a long road ahead for a street-legal version. That being said, the attached press release does indicate that prototypes are currently in development for real-world testing.

Why it matters

According to computer models, such a road-going version of the DeltaWing racecar would return unadjusted EPA fuel economy estimates of 74 mpg on the highway along with a combined rating of 57 mpg. DeltaWing Technology Group says that this would be enough to meet the stringent 2025 CAFE standards today, and if it were made available today, would make it "America’s most fuel efficient internal combustion engine vehicle."

Press Release

DeltaWing Technology Group, Inc. today released the results of an independent engineering analysis of a four-passenger road car concept based on the patented DeltaWing® narrow front track vehicle architecture that showed it would achieve an unadjusted EPA fuel economy rating of nearly 74 mpg Highway and over 57 mpg combined rating. If it was available today, those figures would not only make it America’s most fuel efficient internal combustion engine vehicle, it would meet the 2025 CAFE standard today.

Indeed, those ratings based on an internal combustion, 1.4-liter gasoline engine would make the DeltaWing® four-passenger model even more fuel efficient than all of today’s available hybrids.

Through a board-level relationship with the International Council on Clean Transportation (ICCT), DeltaWing Technology Group recently commissioned Meszler Engineering Services to model fuel economy performance of a four-cylinder, 138-horsepower DeltaWing® four passenger automobile. Meszler’s proprietary computing model calculated from all available data points including weight, power, drag coefficient, frontal area, rolling resistance, and many more.

The efficiency and performance of the DeltaWing® vehicle architecture can be defined as a “green technology multi-tool.” The architecture can accept virtually any current or future transverse engine powertrain and deliver significant fuel savings and green benefits when compared to traditional vehicle designs. The DeltaWing® platform also can be fitted with all-electric or hybrid powertrains; today’s smaller and lighter high-efficiency gas, diesel and compressed natural gas (CNG) engines; and even tomorrow’s hydrogen fuel cells. As a result, it can:

Reduce EV range anxiety and help put more EVs on the road, further reducing emissions and helping improve air quality
Further extend a diesel-powered vehicle’s already impressive range
Reduce emissions from gasoline-powered vehicles by up to 42 percent
And even extend the range of hydrogen fuel cell-powered vehicles

“I’m very pleased to see how this objective testing validates and even exceeds our initial estimates,” said Don Panoz, DeltaWing Technology Group chairman and CEO. “This key milestone allows us to immediately move forward with our plans to build prototype two- and four-seat DeltaWing® vehicles and begin real-world testing.”

Brian Willis, DeltaWing Technologies’ newly appointed vice president, Engineering and Design, will lead the development of two- and four-seat DeltaWing® road car prototypes, as well as the testing program.

Willis is no stranger to Panoz and racing. His 27-year career includes stints as senior designer for Williams Grand Prix Engineering Ltd., director of engineering for Élan Technologies’ motorsports division, chief engineer for Panoz Motorsports, and technical director for Audi Sport Japan, winners of the 2004 24 Hours of Le Mans with the Team Goh Audi R8. Most recently, he was director of technical services for Multimatic Inc. in Canada.
