Virginia International Raceway

Alton, Virginia · 5.28 km · 3.28 mi · clockwise

Virginia International Raceway in Alton, Virginia is a 5,277 m (3.28 mi) clockwise circuit with 13 modeled corners and a substantial elevation envelope: the surveyed centerline runs from 112.7 m to 151.3 m, accumulating 57.1 m of climbing per lap. The simulated speed profile splits the lap cleanly. The fast material sits at Turn 2 (NASCAR Bend), which the model enters at 174 km/h (108 mph), through the 124.2 m-radius South Bend sweeper held above 137 km/h (85 mph), and out of Hog Pen, where the downhill exit builds to roughly 158 km/h (98 mph) onto the front straight. The slow heart of the lap is Turn 6 (Oak Tree Curve), where a 20.9 m effective radius pulls the simulated minimum down to 56 km/h (35 mph) while the track climbs about 5 m. Simulated lap estimates range from 121.3 s (liter bike) to 129.8 s (middleweight twin), with lap averages of 145-155 km/h (90-96 mph). All figures are physics-simulation estimates, not measured data.

The lap's first braking event is also one of its biggest. Arriving at the end of the front straight, the simulation begins braking 171 m before turn-in on the supersport 600 — 210 m on the liter bike, which carries more straight-line speed to shed — entering this 30 m-radius right-hander at 104 km/h (65 mph) and bottoming at 68 km/h (42 mph). The corner is essentially flat, with only 0.1 m of elevation change over its 234 m modeled length. Because a long acceleration zone follows, exit speed matters here: the model leaves at 129 km/h (80 mph) on the 600 and liter bike, 125 km/h (78 mph) on the twin. Simulation estimates only.

Madison Avenue opens one of the slowest stretches of the lap. Its 34 m effective radius funnels into one of the tightest sections of the circuit, and the corner gains 2.3 m over 93 m of modeled length. The simulation brakes early and hard — 114 m before the corner on the supersport 600, and fully 162 m on the liter bike — from 147 km/h (91 mph) down to 71 km/h (44 mph). The uphill grade adds normal load on the brakes but limits acceleration afterward; the modeled exit is 71 km/h (44 mph) on all three classes. All numbers are simulation estimates.

The Roller Coaster earns its name in the data: this 48.2 m-radius right drops 6.8 m over 99 m, the steepest descent of any corner in the model. The simulation brakes hard on approach — 147 m on the supersport 600, 183 m on the liter bike — entering at 112 km/h (70 mph) and dipping to 86 km/h (53 mph). Gravity then does real work on exit: despite the modest radius, the modeled exit speed of 106 km/h (66 mph) claws back most of the entry speed. The downhill grade also reduces the available braking and drive force in the model's grade-aware friction budget. Simulation estimates only.
