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 between 68.7 and 87.6 km/h (43-54 mph), and the Turn 10-12 sequence, bottoming between 68 and 78.1 km/h (42-49 mph). The fast half is the flowing middle third — Turns 5, 6 and 8, each held above 119 km/h (74 mph) — and the Turn 13 kink, taken at 164.5 km/h (102 mph) on a supersport 600. Simulated lap times range from 94.37 s (liter bike) to 97.85 s (middleweight twin). All figures are physics-simulation estimates.

The lap opens with a right-hander — 162 m of curved track on a 31 m effective radius, climbing 0.3 m through its length. In the simulation a supersport 600 arrives at 107.2 km/h (67 mph), begins braking 144 m before turn-in, and settles to a 68.7 km/h (43 mph) minimum, one of the slowest points on the circuit. The liter bike carries the same speeds but needs its brakes 162 m out, while the middleweight twin, arriving at 107.3 km/h (67 mph), starts slowing only 108 m before the corner. All three classes exit between 113.1 and 115.7 km/h (70-72 mph). These figures are physics-simulation estimates, not measured data.

Turn 2 differs from Turn 1 in the model's geometry — a wider 50.7 m effective radius, a much shorter 78 m length, and 1.7 m of climb — and it bends left, the first of only four left-handers on the lap. Simulated entry and minimum speeds are 115.7 km/h (72 mph) in, 87.6 km/h (54 mph) at the apex for the supersport 600, with braking beginning 99 m out (99 m for the liter bike, 99 m for the twin). The exit is slower than Turn 1's, with the four-cylinder classes reaching 101.2 km/h (63 mph) and the twin 100.7 km/h (63 mph). All numbers are simulation estimates.

Another quick right, longer than Turn 5 and slightly tighter: 105 m long, 102.5 m effective radius, and a slight descent at -0.8 m. In the model the supersport 600 arrives at 133.6 km/h (83 mph) and brakes 93 m out — notably earlier than for Turn 5 despite the lower entry speed, since the two corners run back-to-back. Minimum speed is 124.7 km/h (77 mph) across all three classes; the twin's braking begins only 63 m before turn-in. Exit speeds reach 133.6 km/h (83 mph) on the four-cylinder classes, 132.2 km/h (82 mph) on the twin. Physics-simulation estimates only.
