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 161 km/h (100 mph), through the 92.9 m-radius South Bend sweeper held above 118 km/h (74 mph), and out of Hog Pen, where the downhill exit builds to roughly 150 km/h (93 mph) onto the front straight. The slow heart of the lap is the Turn 8-10 complex around Madison Avenue, where a 13.3 m effective radius pulls the simulated minimum down to 44 km/h (27 mph) while the track climbs about 5 m. Simulated lap estimates range from 125.3 s (liter bike) to 133.0 s (middleweight twin), with lap averages of 143-151 km/h (89-94 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 153 m before turn-in on the supersport 600 — 186 m on the liter bike, which carries more straight-line speed to shed — entering this 36.5 m-radius right-hander at 123 km/h (76 mph) and bottoming at 74 km/h (46 mph). The corner is essentially flat, with only 0.1 m of elevation change over its 249 m modeled length. Because a long acceleration zone follows, exit speed matters here: the model leaves at 159 km/h (99 mph) on the 600 and liter bike, 153 km/h (95 mph) on the twin. Simulation estimates only.

Madison Avenue opens the slowest stretch of the lap. Its 13.3 m effective radius is the tightest on the circuit, and the corner gains 5.1 m over 198 m of modeled length. The simulation brakes early and hard — 129 m before the corner on the supersport 600, and fully 177 m on the liter bike — from 130 km/h (81 mph) down to a lap-low 44 km/h (27 mph). The uphill grade adds normal load on the brakes but limits acceleration afterward; the modeled exit is 118 km/h (73 mph) on the faster classes, 116 km/h (72 mph) on the twin. All numbers are simulation estimates.

The right-hand middle segment of the Madison Avenue complex carries the same modeled parameters as Turn 8: a 13.3 m effective radius, a 5.1 m climb, and 198 m of length. The simulation's speed trace repeats accordingly — braking begins 129 m out on the 600 and 177 m out on the liter bike, entry is 130 km/h (81 mph), the minimum sits at 44 km/h (27 mph), and the exit reaches 118 km/h (73 mph). At this radius the model is entirely traction-limited, which is why the 90 kW supersport and the 150 kW liter bike post the same corner speeds; only their brake-zone lengths differ. Physics-simulation estimates throughout.
