DeltaWing has unveiled its radical proposal for the future IndyCar Series chassis, which will be introduced in 2012.

The new company is one of four contenders for the new design, along with existing supplier Dallara and former Champ Car constructors Lola and Swift.

The DeltaWing programme has generated huge anticipation as it was long-rumoured to be the most radical of the concepts vying for the IndyCar deal, and because it is backed by a number of leading teams, having been designed by Chip Ganassi Racing's Ben Bowlby, formerly Lola's chief designer.

The proposal was officially unveiled at the Chicago Auto Show today, having been in development since January 2009. Its striking shape features an extremely narrow front end and wide rear, and tyres largely enclosed by bodywork. Its unusual body style has been designed specifically to encourage close racing and to minimize aerodynamic disturbance in the car's wake.

DeltaWing chief executive officer Dan Partel believes the car could revitalize American single seater racing if it is accepted by the Indy Racing League.

"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," he said. "This radical prototype takes open wheel racing to a new level from both an engineering standpoint and the overall spectator experience."

The DeltaWing is designed to achieve speeds of 235mph with engines with only half the power and fuel consumption of the current IndyCar Hondas, thanks to a large reduction in weight and aerodynamic drag.

"The first prototype car will be powered by a 2.0 litre four cylinder turbocharged engine," said a DeltaWing statement.

"Final horsepower figures will be based on the car's performance on the track, but by using state-of-the-art computer modeling, it is anticipated that the engine will need to produce approximately 300 horsepower to attain the performance targets and will run over 4,000 miles before requiring a rebuild, a dramatic 100 per cent improvement over the current engine."

Partel said the engine characteristics had been developed with environmental concerns in mind.

"We are confident that this car will outperform the current generation IndyCar and do it in a more environmentally friendly way," said Partel.

"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 plans to start testing its first prototype in August this year.

Bowlby added that the new car should also achieve a massive cost reduction for IndyCar teams.

"As we design the DeltaWing prototype, safety, efficiency, value and cost are our main priorities," he said. "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."

Bowlby does not want the DeltaWing to become a spec chassis for the IndyCar Series, and wants multiple chassis builders to be able to enter cars built within the rules framework established by his concept.

"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," he said.

That's not exactly an open-wheel racer any more... but I'd really like to see something like that on tracks. Preferably propelled by engines that are actually production based (thus forcing manufacturers to make better engines for road cars).
 
If Tyrell was still alive in F1, this could be their 2010 racer.

Not even "not exactly"; it just isn't. Just because there's a slit in the bodywork above the wheels doesn't all of a sudden make it open-wheel. The wheels usually have to be, y'know, exposed.

I don't like the design, either. They just put wheels on the sides of an SR-71 mockup and called it a day.

Pretty much what he said.
 
As narrow as that front track is, it looks like it would be more at home on a drag strip instead of a race track. That said, Indy does to ovals, so there isn't much turning. Still seems too narrow.
 
A design like that would not be able to handle a road course very well. Road racing is already half of the season, and likely to increase.
 
Now I'm thinking of the benefits of full sized airplane wings flipped for downforce on F1 cars...:lol:
 
this is for Oval racing right?

i cant see that being very good in corners. i mean the front track is very narrow and so at the wheels, and its a long car.... tight corners = understeer surely?

also, with the wide rear track, if you hit the apex right with the front your gonna be all over the curbs at the back.

oval racing on the other hand.... could work out pretty well.

Looks crazy, which is nice, but as you guys have said, there is no way this can work on a proper race track (that isn't a circle)...
 
Well, considering it probably only weighs half of what a McLaren F1 weighs, and had 627hp. Weighs half as much, has half the power, but it much more aerodynamic, which is needed to battle the exponential drag the higher speeds create, which you would normally need lots of hp to overcome...seems plausible.

Aerodynamics yes, but weight has less to do with top speed. The veyron weighs over 2000kg, almost double the mclaren but it doesn't have double the power.

How stable could this possibly be at 235mph? And how much downforce are they sacrificing by being able to make those kinds of speeds?

Weight has nothing to do with top speed. In order for this car to reach 235 mph with 300 horse power it is going need to have a very low CDa value, and if it is going to have low drag it must be sacrificing downforce or it must have a very small cross sectional area compared to other cars.
