#2 Ice VDA

  • 164' wide  X 3,000' long
  • Ice pad configuration supports accelerated run ups, steering input and braking at higher speeds. Generous packed snow, non-trip run off, is provided on all sides.
  • Safety is maintained during intentional or non-intentional system failure.
  • Lighted for 24-hour test capability.

#3 Packed Snow VDA

  • 600' wide X 3,600' long (50 acres)

#4, 10 & 11 Autocrosses

  • (#4) 40' wide X 1.1 miles long
  • (#10) 40' wide X .9 mile long
  • (#11) 40' wide X .5 mile long w/ 200' R circle
  • Designed for handling; each course varies in its radius of turns (increasing and decreasing) and length of straight-aways. Snow compaction is to customer specifications.
  • Each course was designed with safe run off and maintained with no snow berms.
  • #4 (1.1 mile) is lighted (low level) for 24-hour test capability.

#6 Slush Pool

  • 11.5' wide X 164' long; depth is customer specified.
  • This unique course is operated in temperatures from –30ºC to –7ºC. Vehicles are driven into the heated slush trough and onto course #4 autocross to pickup snow on the underbody components. Adjacent Building #300 supports inspection and photography of underbody snow and ice build up. After completing the prescribed replications, the vehicle(s) can be soaked at ambient or in an AET cold cell, after which effects can be evaluated with a drive and cold inspection in Building #300.
  • Vehicles can be de-iced in AET’s high-pressure car wash for a retest.
