Grand Prix Dynamics & Line Optimization

Apex & Telemetry Racing Line Analyzer

Simulate cornering physics, trail-braking, apex clipping, lean angles, and exit drive. Compare aggressive vs wide lines to discover winning lap-time deltas.

Corner Setup

Entry Straight Speed 308 km/h

Braking Point Marker 118 m before corner

Lighter marker = later braking, higher trail-brake demand.

Apex Geometry & Clipping Late Geometric Apex (+14%)

Negative = Early Apex (tight entry); Positive = Late Apex (better drive).

Loaded baseline telemetry. Tweak braking marker or apex bias to simulate line variance.

The Geometry of Late Apex

Sacrificing minimum apex speed to rotate the machine early allows earlier throttle pickup. At Spielberg Turn 3, late apexing straightens the corner exit, translating into +6 km/h down the straightaway.

Kamm's Friction Circle & Lean

Tire grip is finite. Under heavy trail-braking, longitudinal brake force consumes grip, requiring lean angle reduction. Maximum lean (64°) occurs at zero longitudinal braking load.

Micro-Sector Telemetry Deltas

A racer losing 0.08s at entry can recover 0.22s on corner exit. The net micro-sector delta determines whether an overtake sticks or leaves the rider vulnerable to a cutback.
