An analysis of the Deltawing’s viability showed a four seat version would reach close to 74 mpg on the highway.

DeltaWing Technology Group, Inc. 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.

The study 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 also meet the 2025 CAFE standard.

Those ratings are based on a version powered by an internal combustion, 1.4-liter gasoline engine.

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 other variables.

Technically, the Deltawing can be powered by any current technology available, be it conventional gasoline or diesel, or hybrid, electric or hydrogen.


“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.”

The company also stated 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.
