The designs have left the engine largely uncovered, letting the fans get a better view of them. Swift's director of motorsports, Casper Van der Schoot, explained that; "Our wind-tunnel tests have shown the engine cover has very little effect on aerodynamics compared to most other components on the car. We saw an opportunity to showcase the engine and other ‘jewelry' while preserving efficiency with a much smaller fairing.”

Swift has also been working on ways to improve passing and help the fans in the stands to understand what is going on in real time. Towards that end, Swift's concepts include the 'mushroom buster' - an aero device at the rear of the car that breaks up the mushroom-shaped areo wake, aiding any following cars in closing up. They are also working on a concept called 'Swift lights', a strip of 1 millimeter thick display light that will tell the fans how much throttle is being used, when the driver is on the brakes, and so forth.

Here are a few of the concept drawings:

Swift Engineering has provided chassis for several racing series over the past twenty-seven years, including the CART series from 1997-2000. They are currently the sole chassis provider for the Toyota Atlantic Championship.

I am still looking for drawings of Lola's IndyCar submission. The Delta Wing concept is due to be revealed to the public on Wednesday - I should have an article with images of it on Thursday.
