This months Race Car Engineering has its "Class of '98 GT Special Report".  In it an interesting technical description of the Toyota GT-One.  I put this graphic together based on the information in the Race Car Engineering article because for me, pictures speak way louder than words.

"Air flowing under the nose of the car is split above and below the leading edge of the flat floor.  The air flow over the upper surface of the floor is diverted laterally by the sides of the tub, and exhausted through large scavenge vents in the side body panels behind the front wheels.  Airflow over the top surface of the nose is fed to the side-mounted water coolers and turbocharger intercoolers through ducts formed in the doors" (Race Car Engineering, V8N7 August 1998).

The concepts Toyota is using is similar to that on the BMW LMP '98.  But instead BMW utilizes the airflow coming from the underbody to feed a cooler.  The Toyota takes air in for its coolers via intakes either side of the cockpit.  All pretty complicated aerodynamics if you ask me!  According to Dave Lynn, "With all the gaping holes on the Toyota its a little hard to tell what air is going where!".  Couldn't have said it better!

This image is out of the August/September 1998 (#19) issue of  Race Tech Magazine and better illustrates the Toyota GT-One's nose underbody packaging.
