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.->ke148 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,->ke1030 hybrid,->ke147 hydrogen fuel cell and any transverse internal combustion engine including gasoline, diesel->ke1917 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."
