Cd 0.075 (the impossible just took a little longer)

At the "Fuel-Efficient Vehicles-Now!" website,aerodynamics appendice,table of photos and drag coefficients,at the top of page,is the pac car II Shell Eco-Marathon competition winner.They claim Cd 0.075 for the car.A few years ago this would have been the claim of a madman! At the pac car website,they offer the "shape" of the car in CAD form for 100 Euros.----------- This is remarkable! Contemporary wisdom had it that Cd0.10 was the lower limit for a vehicle on the ground.----------------------------------- The web address(lets see if I can do this without screwing it up) is ETH - PAC-Car II - Welcome to the PAC-Car II website! This really raises the bar for aero-modding potential.
