The NHRA Mello Yello Drag Racing Series rolled into Las Vegas for the inaugural 4-wide Denso Spark plugs NHRA Nationals. This is the first time NHRA has brought the 4-wide concept to the western part of the United States. There is only one other facility that runs 4-wide and it’s located in Charlotte, NC. The concept is that four cars go down the racing surface and the first two to cross the finish line in each quad comes back to race the following round.
