Aerodynamic Drafting & Dirty Air
At 190+ MPH on the Las Vegas 1.5-mile tri-oval, aerodynamic drag accounts for over 75% of total engine load. Running within 1.5 car lengths behind a lead car cuts aerodynamic drag by 28%, giving a +6 to +9 MPH slingshot advantage. However, trailing closely in "dirty air" starves the front splitter of downforce, pushing the car toward the outside retaining wall and blistering the right-front tire.
Progressive 20° Banking Physics
Las Vegas features 20 degrees of progressive banking in Turns 1 through 4. Centripetal acceleration exerts up to 2.8 lateral G-forces on the stock car chassis. The low line offers the shortest distance around the 1.5 miles (saving ~45 feet per lap), but the high line lets drivers carry higher exit momentum onto the 1,500-foot backstretch.
Undercut vs. Overcut Pit Cycles
Because fresh Goodyear tires generate over 1.2 seconds per lap in immediate pace improvement, pitting 2 to 3 laps before the competition (the "undercut") can overcome a multi-second deficit. However, 2-tire right-side stops cut pit road dwell time from 9.8s down to 4.2s, making track position paramount in late-race Vegas shootouts.
