Both patents are dated from March 2015 and are simply titled Street Car. However, the two designs are radically different. One of them (pictured above) is essentially a take on the current DeltaWing racecar. Like the competition version, there's a narrow front end that leads to a bulbous passenger compartment. There doesn't appear to be much rearward visibility from this shape, though – without a few cameras at the back, pulling out of a parking spot could be quite a challenge.
Conversely, the second design (inset) looks far more ready for the road. It features a less extreme take on the narrow front, wide rear shape, and the result is a far less bulging look than the other patent depicts. With mirrors on each side and a split rear window, option two appears far more drivable.
The two patents are only for the overall design, and there's no mention of intended powertrains for either of them, although DeltaWing claims to be at work developing two- and four-passenger road cars. Initial calculations indicate a 1.4-liter four-cylinder making 138 horsepower could allow for combined fuel economy of around 57 miles per gallon.
The DeltaWing road car project has been underway since at least last year. At the time, the company showed a rendering for a four-seat model that blended the style of these two, patented designs.
