New Jersey Motorsports Park - Thunderbolt
Millville, New Jersey · 3.50 km · 2.17 mi · clockwise
Thunderbolt, the longer of the two road courses at New Jersey Motorsports Park in Millville, runs 3.5 km (2.17 mi) clockwise through fourteen numbered corners. The circuit is nearly flat: elevation in the model spans just 18.4 m to 24 m (60-79 ft), with 16.4 m (54 ft) of total gain per lap, so grip and line rather than gradient define the rhythm. The simulation's speed profile splits the lap cleanly in two. The slow half is the Turn 1-4 complex opening the lap, where minimum speeds sit near 74.5 km/h (46 mph), and the Turn 10-12 sequence, all pinned at 77.6 km/h (48 mph). The fast half is the flowing middle third — Turns 5, 6 and 8, each held above 112 km/h (70 mph) — and the flat-out Turn 13 kink, taken at 169.5 km/h (105 mph) on a supersport 600. Simulated lap times range from 90.39 s (liter bike) to 94.54 s (middleweight twin). All figures are physics-simulation estimates.

- Length: 3.5 km (2.17 mi), 14 corners, run clockwise
- Elevation range: 18.4-24 m (60-79 ft); 16.4 m (54 ft) total gain per lap — effectively flat
- Simulated lap time (physics estimate): 91.62 s supersport 600, 90.39 s liter bike, 94.54 s middleweight twin
- Simulated average speed: 137-138.8 km/h (85-86 mph) for the two four-cylinder classes
- Fastest point in the model: Turn 13 kink, 169.5 km/h (105 mph) minimum with no braking
- Slowest corners in the model: Turns 1-4, each bottoming near 74.5 km/h (46 mph)
- Eleven of the fourteen corners turn right, matching the clockwise direction

The lap opens with a long right-hander — 329.9 m of curved track on a 36.6 m effective radius, climbing 2.8 m through its length. In the simulation a supersport 600 arrives at 137.5 km/h (85 mph), begins braking 129 m before turn-in, and settles to a 74.5 km/h (46 mph) minimum, one of the slowest points on the circuit. The liter bike carries the same speeds but needs its brakes 177 m out, while the middleweight twin, arriving at 137.7 km/h (86 mph), starts slowing only 87 m before the corner. All three classes exit between 113.1 and 114.1 km/h (70-71 mph). These figures are physics-simulation estimates, not measured data.

Turn 2 mirrors Turn 1 almost exactly in the model's geometry — the same 36.6 m effective radius, a nearly identical 335.9 m length, and 2.7 m of climb — but it bends left, the first of only three left-handers on the lap. Simulated entry and minimum speeds match the previous corner: 137.5 km/h (85 mph) in, 74.5 km/h (46 mph) at the apex for the supersport 600, with braking beginning 129 m out (177 m for the liter bike, 87 m for the twin). The exit is slightly quicker than Turn 1's, with the four-cylinder classes reaching 119.9-120 km/h (75 mph) and the twin 117.6 km/h (73 mph). All numbers are simulation estimates.

A 293.9 m right-hander on the familiar 36.6 m radius, gaining 2.9 m — the largest single-corner climb on this flat circuit. Because Turn 2's exit leads almost directly into it, the simulation shows a compressed approach: entry is only 101.1 km/h (63 mph) for the supersport 600, yet the model still begins shedding speed 171 m before turn-in (218.9 m on the liter bike, 129 m on the twin), reflecting braking that starts back in the preceding section. Minimum speed again sits at 74.5 km/h (46 mph), with the twin fractionally lower at 74.4 km/h. Exits match Turn 2: 119.9-120 km/h (75 mph) for the fours. These are physics-simulation estimates.
