When the NHRA Mello Yello Drag Racing Series’ best drivers line up to race at the Dollar General NHRA Four-Wide Nationals fueled by Full Throttle at zMAX Dragway April 19-21, fans can expect plenty of adrenaline-packed racing at the world’s only four-lane, all-concrete drag strip.

The greatest spectacle in drag racing brings three days of excitement unlike anything else in sports, with the fastest-accelerating machines on the planet unleashing a nitro-fueled assault on the Bellagio of drag strips.

Here are some essential facts about the fourth-annual Dollar General NHRA Four-Wide Nationals, by the numbers:

Nearly 40,000 horsepower will roar to life on each Top Fuel and Funny Car run at the Dollar General NHRA Four-Wide Nationals. The four-wide action packs almost as much punch as an entire 43-car NASCAR Sprint Cup Series field.

Fans come from around the world to see the NHRA’s best Top Fuel, Funny Car, Pro Stock and Pro Stock Motorcycle drivers battle for Wallys at zMAX Dragway. In 2013, fans will come from 44 states and nine foreign countries, including Germany, Finland, Sweden, England, Brazil and Australia, to witness the excitement of a four-wide frenzy.

In preparation for April’s Dollar General NHRA Four-Wide Nationals, track crews will paint almost six miles of retaining wall at zMAX Dragway.

Safety-Kleen, the facility’s waste management provider, will recycle 3,000 gallons of used oil, solvents and fuels at the three-day event, along with all of the oil filters, oily rags and aerosol cans used throughout the weekend.

Top Fuel dragsters and Funny Cars accelerate from zero to 100 mph in less than 0.8 seconds and reach top speeds in excess of 300 mph. The current NHRA Top Fuel national speed record of 332.18mph was set by Spencer Massey during last year’s Four-Wide event.

Each nitro methane-powered Top Fuel dragster and Funny Car burns between 11 and 12 gallons of fuel per pass. At that rate, these monster machines would need nearly 50 gallons to travel just one mile.

Each pair of Goodyear tires on a Top Fuel dragster or Funny Car costs about $1,500, and must be replaced on average every three to four runs.
