Recently IRL put out a new tender for cars.
Lola,
Dallara,
Swift and Delta Wing Group have shown interest.
3 of them have released details:

At the heart of Lola’s presentation to the IRL Board was a carefully considered modern dual body style approach. This concept will provide two ready to race aero performance balanced Indycars that could compete even safer side by side and very close behind one another on all circuits. This would provide a unique focus for drivers, teams and fans alike without technical compromise or advantage and in addition would accommodate a dual engine supply situation if required.
Now, I have a few questions I hope you can answer.
1) What's a dual-body?
2) A dual-engine. Is that 2 engines running at the same time?
This proposal, to me, seems to be very interesting. If the 2 engines running at the same time idea is true. I can see situations for advancing engine usage, such as selectively closing off certain cylinders to increase distance between fuel-stops.
From what I've seen of Indycar, admittedly not much, they do try to stay out for as long as they possibly can and tend to gain many places by doing so.

Safety has been improved with increased resistance to frontal lift and improved yaw stability. Improved raceability also has been addressed in the design with less sensitive aerodynamics in traffic for better overtaking and the reduced incidence of wheel-to-wheel contact.
The cost of the complete package to compete on a variety of racetracks (superspeedway, speedway, short oval, road course and temporary circuits) will be reduced to 55% of the current car cost. Teams will carry much smaller quantities of spares because it requires less parts specific to individual types of tracks, which is another cost saving measure.
I couldn't get a link directly from their site, but their is information there.
The Dallara from Autosport
Swift Engineering gave no information on its car. However they've released images. They appear to have 2 seperate designs. One seems entirely conceptual and one, more realistic.
Delta-Wing are releasing details later.
Here's a comparison picture, to show the difference they're making in the design of the car:
