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
