Indianapolis-based DeltaWing LLC has become the latest contender to unveil its vision of the future for US open-wheel racing, after taking the covers off its radical IndyCar design at the Chicago Auto Show.

Initial work on the concept was started from a clean sheet by Briton Ben Bowlby at Target Chip Ganassi Racing just over a year ago, and aims at realigning America's premiere racing tradition with current automobile industry and consumer trends, DeltaWing has called on technological innovation to return racing to cutting edge relevance in the search for extreme performance with less environmental and financial resources. It's unveiling follows those from rivals Dallara, Lola and Swift.

"Today marks a fundamental shift in how race fans and the general public will view all racing cars in the future; this is a game changer" said CEO Dan Partel, "This radical prototype takes open-wheel racing to a new level from both an engineering standpoint and the overall spectator experience."

The car also marks the next step in the industry's dedication to becoming more environmentally responsible. DeltaWing has identified that this marketplace trend can be applied to the IZOD IndyCar Series and has developed this concept car using the most advanced American technology.

By targeting reduced aerodynamic drag and lighter weight, the DeltaWing design achieves record breaking on track performance with only half the engine power of its recent predecessors. The unique vehicle design provides optimum and consistent distribution of loading for the Firestone Firehawk tyres, which are specifically developed for the dynamic characteristics of the DeltaWing racer.

The futuristic form aims to appeal to a younger demographic audience who is increasingly in search of technological innovations to solve the requirement for sustainable personal mobility. DeltaWing LLC will design, engineer and supply a running prototype by August 2010.

Revolutionary from every angle, the design features an ultra-narrow front track to saves weight, while fairings for the tyres reduces aerodynamic drag and prevents wheel interlocking. The Delta plan view shape provides undisturbed airflow to the downforce generating ground effect underbody venturi located beneath the car's centre of gravity just ahead of the widely spaced rear wheels, while highly efficient downforce, produced with negligible wake, ensures minimal loss of aerodynamic performance for a trailing car, thus enhancing the on-track overtaking spectacle.

Uncluttered side view with rearwards driver location provides for the IRL-mandated sponsorship opportunities while, according to the constructor, also adheres to 'true single-seater appeal'. The highly prominent tail fin replaces the conventional inverted aerofoil in order to broaden the 'yaw stability envelope' without inducing aerodynamic drag on straights.

"We are confident that this car will outperform the current generation IndyCar and do it in a more environmentally friendly way," Partel continued , "Auto racing has always
been a powerful marketing tool for propelling new technology into the hearts and minds of consumers. This new car was specifically designed to be more closely aligned with the new reality of automobiles that are arriving on the road today. Consumers are choosing cars that provide impressive performance capabilities but with greater fuel efficiency. This prototype IndyCar features those same characteristics, making it much more relevant to the public and the auto industry. It is our goal to make participation in the series highly attractive to the automobile manufacturers as well as the fuel, technology, information and entertainment corporate sectors."

DeltaWing anticipates the final car will weigh a massive 50 per cent less than the current generation Dallara IndyCar and crucially, generate only half of the aerodynamic drag. This combination requires substantially less horsepower to generate speeds of over 235mph while delivering a 100 per cent improvement in fuel efficiency.

"Our goal is to have our first prototype on the track in August," Partel confirmed, "We look forward to an exciting development project with the Indy Racing League to
ensure that all of their requirements are met for DeltaWing to become the next IZOD IndyCar in 2012."

The first prototype car will be powered by a two-litre, four-cylinder turbo-charged engine. Final horsepower figures will be based on the car's performance on the track, but by using state-of-the-art computer modelling, it is anticipated that the engine will need to produce approximately 300 horsepower to attain performance targets and will run over 4000 miles before requiring a rebuild, a dramatic 100 per cent improvement over the current engine.

"The DeltaWing Concept is more than just a new and exciting racing car; it is about creating a platform that moves racing into the new era of information entertainment", Bowlby commented, "Once we have successfully production engineered and manufactured the first generation of team cars, those cars will form the beginning of a constant evolution formula.

"Our intention is to publish the entire design detail via the DeltaWing website where access will be available to everyone and so provide a unique participation opportunity and insight into the engineering world of modern racing cars. Just as we hope to see multiple engine suppliers with different configurations and displacements, we also hope to create a framework that will allow us to see a varied and ever changing grid of racing machines in a sustainable, cost controlled and high value manner. We will be unveiling these plans once the prototype is up and running.

"As we design the DeltaWing prototype, safety, efficiency, value and cost are our main priorities; the goal is that more teams and drivers will have the opportunity to compete in the IZOD IndyCar series. At this point we anticipate a complete car with engine will sell for $600,000."
