DeltaWing Technology Group is continuing to develop its namesake model into both a GT-class racer and a future, two-seat production car. Both get real-world unveilings at this year's Petit Le Mans at Road Atlanta. While this is their first showing in physical form, the company teased this effort with several mechanical renderings in March.

Now dubbed the Panoz DeltaWing GT, the blue, two-seat road car concept echoes the look of the earlier four-passenger version. However, the front end now comes to a sharper point, and the side pods get a complete redesign. It may not be beautiful, but at least it looks a lot better than the previous patent images. The tweaks also give the revised shape a drag coefficient of 0.26, the company claims. There's still no powertrain under the swoopy bodywork, and Panoz doesn't offer any hints by mentioning hybrid, fully EV, gasoline, diesel and compressed natural gas as potential options.

Meanwhile, the racecar chassis concept offers a tiny hint at what's going on beneath the street-legal version's shell. Some parts for the steering and suspension are a result of developments for the current DWC-13 Coupe. While there are no official plans to begin competing on the track yet, DeltaWing plans to start testing the GT racer by the end of the year. The company is developing it with 350-400 horsepower in mind and a weight of 1,800-2,000 pounds.

DELTAWING TECHNOLOGY GROUP UNVEILS DELTAWING GT CONCEPT

Concept car showcases DeltaWing® design in a new form and one step closer to a highly efficient street-legal two-seat GT car

Company also displays DeltaWing GT race car concept chassis that is the foundation of the street-legal car's underpinnings

DeltaWing Technology Group to conduct real-world testing by the end of 2015

Braselton, Ga., Oct. 1, 2015 – DeltaWing Technology Group today revealed at Road Atlanta a full-size concept of what a Panoz DeltaWing GT street-legal car could look like, as well as a DeltaWing® GT race car concept chassis, providing a glimpse of the fuel and energy efficient DeltaWing® architecture in another form. The display showcases the company's rapid progress toward a new DeltaWing race car and ultimately a highly efficient Panoz DeltaWing® car for the street.

Both are on display Oct 1-3 in the DeltaWing Racing Cars and Panoz exhibit in Road Atlanta's Vendor Village. Road Atlanta is home to the 18th Annual Petit Le Mans powered by Mazda, the finale of the 2015 TUDOR United SportsCar Championship and the Tequila Patrón North American Endurance Cup season.

The Panoz DeltaWing GT concept car and DeltaWing GT race car concept chassis broke cover just six months after DeltaWing Technology Group's March 2015 announcement that it would begin developing a DeltaWing GT race car concept. Development began immediately after the company received 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 analysis showed it could achieve nearly 74 mpg highway and 57 mpg combined.

The team then focused on further refinement of the architecture and design, preparing for prototype development. As a result, the Panoz DeltaWing GT road car design's coefficient of drag in simulation has been optimized and currently is in the 0.26 Cd range.

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. 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

Applying lessons learned through DeltaWing racing

Sports car endurance racing fans are familiar with the DeltaWing. It debuted as the inaugural Garage 56 entry at the 2012 24 Hours of Le Mans and quickly proved it could compete with technology rather than brute horsepower. Today the Claro/Tracfone DeltaWing Racing Cars DWC-13 Coupe competes in IMSA's 2015 TUDOR United SportsCar Championship with about half the weight and aerodynamic drag, half the horsepower, and half the fuel consumption while delivering the same performance as its competitors.

The DeltaWing Technology Group engineering and design team leverages the data acquired through racing and applies it to next-generation projects like the DeltaWing GT. For example, many DeltaWing GT race car concept sub-assemblies like steering and suspension are derived from the DWC-13 Coupe, and what has been learned about the DWC-13's driving dynamics influence the direction of the DeltaWing GT street and race projects. Preliminary DeltaWing GT race car concept targets call for a vehicle powered by a 350 to 400 horsepower engine and weighing about 1,800 to 2,000 lbs, depending on the powertrain.

The goal is to begin real-world testing of a DeltaWing GT race car concept prototype in 2015 to further drive the company's goal of creating both a two-passenger Panoz DeltaWing GT and four-passenger Panoz DeltaWing car for the road. Like the DeltaWing DWC-13 Coupe, the company hopes to acquire valuable data through motorsports but has not announced official plans to race the DeltaWing GT race car concept.
