DeltaWing Tech unveils road car rendering

5 Comments

DeltaWing Technologies Inc. today revealed how the groundbreaking DeltaWing® architecture – a highly aerodynamic and lightweight design currently competing in IMSA sports car road races in the form of the DeltaWing race car – could look as a street-legal, four-passenger car.

The rendering depicts an exciting, aerodynamic car design that evokes motion, energy and speed even at a standstill and is unlike any of today’s road-going automobiles. And yet the innovative DeltaWing® shape is a true form-follows-function design that can significantly reduce aerodynamic drag to help increase fuel efficiency. Another attribute of the shape is considerably less overall mass. When combined with light-yet-strong materials such as lightweight steel, aluminum and advanced composite materials, the result is a car that can deliver any given performance level with significantly reduced fuel consumption and greenhouse gas emissions compared to conventional automobiles.

Intended as a solution for manufacturers facing more stringent fuel economy and emissions standards, the platform offers efficiency benefits whether using new generation smaller and lighter high efficiency gas or diesel powertrains, alternative fuels like compressed natural gas (CNG), or today’s and tomorrow’s hybrid and all-electric powerplants. DeltaWing Technologies Inc. intends to partner with mass-market auto companies that share its vision rather than manufacture independently, thus offering cars with the DeltaWing® architecture to a broad global audience and significantly expanding the design’s efficiency and environmental benefits.

The narrow-track front wheelbase incorporates smaller width tires. The rear-engine design places the center of gravity far to the rear. That results in significantly less weight on the front axles, reducing rolling resistance and further increasing efficiency. Handling is extraordinarily agile, as proven by the narrow front track of the DeltaWing race car competing on America’s most challenging road courses in the IMSA-sanctioned TUDOR United SportsCar Championship.

“Many of the aerodynamic, lightweight and handling benefits of the race car can translate to the street,” said Don Panoz, chairman of DeltaWing Technologies Inc. “We are competing at the highest levels of road racing with half the weight, half the horsepower, and nearly half of the fuel consumption. We believe we can deliver similar results on the street without compromising safety, comfort and performance. We have a formula that’s highly efficient and still fun to drive.”

Panoz also said the DeltaWing race car proves teams do not have to rely heavily on horsepower to be competitive. “Design, technology, efficient use of lightweight materials, lower horsepower and lower fuel consumption is a winning formula. I believe this is the future of motorsports, and key to meeting the next decade’s fuel economy and emissions standards.”

Malcolm Stewart sidelined by knee surgery for ‘extended duration’

The knee injury that kept Malcolm Stewart from mounting up for Anaheim 2 will require surgery and he will be sidelined for “an extended duration” of the Monster Energy Supercross season, according to the Rockstar Energy Husqvarna team.

“I just wanted to give you guys an update,” Stewart said on Instagram. “It’s not the news you guys want to hear, but I took a spill last week and hurt my knee pretty bad to the point that we’re going to have to get surgery done.

“I’m definitely bummed out about it; I felt we were riding pretty good and were just now starting to get the ball rolling, but it is what it is.”

Stewart’s season started with high expectations until accidents in the first two rounds left him 15th in the standings.

He ended 2022 on a high note, finishing a career high third in the Supercross standings. He then missed the start of the Pro Motocross season with another knee injury.

The 2023 season appeared to live up to his expectations. Despite back-to-back accidents, Stewart contended for podiums at both Anaheim 1 and San Diego. He won his heat at San Diego.

“It was very tough to receive the news that Malcolm will need to undergo knee surgery,” Nathan Ramsey, Team Manager for the Husqvarna team said in a press release. “He has worked so hard to be in a position to win races this year and I truly believe he was ready.

“The Rockstar Energy Husqvarna Factory Racing program will support him in every way that we can through his recovery and we can’t wait to get him back on track and back at the races.”

Stewart joins 250 rider Jalek Swoll on the sidelines after he broke an arm in a practice session. Swoll will be relieved by Talon Hawkins beginning this week at Houston, Texas.

A replacement rider has not been announced for Stewart, which means the focus shifts to his 450 teammate Christian Craig, who currently sits 12th in the standings with three top-15s in the opening rounds.
