DeltaWing Entering GT, Eyeing Future Showroom Debut

Coming soon to a track near you, DeltaWing will bring its signature design to the GT class, and eyes set on the showroom down the road.

The latest racing variant is expected to demonstrate on the track “that with far less horsepower than many of today’s best sports cars, a two-seat performance car based on the DeltaWing® architecture would deliver the same performance, yet with previously unimagined fuel economy and efficiency.”

The GT will, like the DWC13 Coupe campaigned by DeltaWing Racing Cars, be a coupe using weight distribution to its advantage, thanks to its narrow nose and wide backside putting 30 percent up front, the rest in back. The project won’t interfere with the team and its efforts in IMSA’s TUDOR series.

Meanwhile, that same basic design forms the basis for two- and four-passenger prototypes that could lead to a road-legal version of the DeltaWing. Preliminary data suggests the design would net “an unadjusted EPA fuel economy rating of nearly 74 mpg Highway and over 57 mpg combined rating,” adding that if one could buy a DeltaWing from the showroom today, they would have a vehicle that was not only the most fuel efficient conventionally powered vehicle in the United States, but would also meet the 2025 54.5 mpg standard. The ratings are for a DeltaWing powered by a 138-horsepower 1.4-liter engine placed in the four-passenger variant.

Aside from traditional ICEs, the company says the prototype could be fitted with hybrid, diesel, CNG, hydrogen and electric power, with results ranging from better range for diesel, EV and FCV versions, to a 42 percent reduction in emissions for gasoline models.

    It's hard to believe that any consumer vehicle built off of this platform would perform adequately on front impact crash tests, especially the offset crash.

      What would be a 'narrow offset' for any other car would be a near-miss with this. If the body shape is 'slippery' enough, such a collision would definitely move this car to the side but could well eliminate the 'hook and twist' effect of such conventional vehicles. It would likely peel off the rear wheel and leave the car burning off energy much more slowly in a slide; saving the passengers from the high-G deceleration with associated high-G sideways velocities which tend to cause more injuries than full-frontal ones. Take another look at how racecars are built. They're meant to peel off energy by peeling off pieces in a high-energy crash. Now look at how all our street cars are built--to absorb that energy rather than deflecting it. Which is really safer, a 200+ G deceleration from 65 to 0 in milliseconds or a 40-G deceleration that takes 5 seconds or more?

  • GregLocock Not interested at all. Apparently I've got Apple car play but I've never used it in 3 years. The built in nav is ok.
  • Corey Lewis Probably worth about what they're asking, given its condition. The color combo isn't a desirable one, they look sharper in non-beige shades. Like two-tone green, maroon, navy, or gray. The end of the time when MB built its cars properly. No shame in turning up in a clean W126, they'll always command respect.
  • Lou_BC Another way to look at this is the upgrading of hardware and software. ...............The average length of car ownership is 10 - 12 years ....................The average lifetime ownership of a cell phone is 2.5 years. ................................................................... My phone will remain up to date, my vehicle won't. Especially if you buy a new "end of run" model.
  • TheEndlessEnigma "...we could be seeing a foundational shift in how Americans and car buyers see Stellantis products." yeah, I view Stellantis products as being off the cross-shop list. Stellantis is doing an excellent job of killing the Chrysler and Dodge brands and turning Jeep into something it isn't.
  • 2manyvettes 495 hp in a base C8 is more than enough. 800+ hp in a ZR1 is not worth the extra $60k (plus dealer markups). Unless the buyer is going for bragging rights. I remember when the C7 Grand Sport came out, and a reviewer got his hands on one and put it on the track at Lime Rock. His conclusion? Save yourself $15k and skip the Z06 and get a Grand Sport.
