Christmas rush brings bumper to bumper race cars

[MultiMatic]

Christmas rush brings bumper to bumper race cars to this wind tunnel every year and this year is no different . Speaking to an aquaintance today who had been there with a non nascar car team , he said it was all Ford Cup teams ahead and behind them with plate cars. I have been told about half of all the nascar teams use this tunnel.
