Algorithmic
Neutrality
Opticars formulas are designed to isolate performance vectors from marketing noise. By normalizing disparate units (Force, Mass, Currency) into a dimensionless 0-1 range, we achieve absolute comparison parity.
Pure Performance
The ultimate measurement of physical capability. Neutralizes weight and rewards efficiency across all dynamic vectors.
Bang For Buck
The Great Equalizer. Calculates raw performance points delivered per 10,000 units of currency.
Trackday Potential
Aggressively penalizes mass and rewards cornering stability (G²) and aerodynamic efficiency (Cx).
Daily Commuter
Focuses on economic sustainability, reliability, and practical utility for everyday life.
Family Trip Score
Prioritizes volume (Boot & Seats), range (Tank Size), and reliability for long-distance comfort.
How /cars Sorting Works
The engine first scans the *current results* of your search to find the minimum and maximum values for every attribute. Your score is relative to the competition in your view.
Every variable (HP, Price, Cons) is converted to a 0-1 range.
score = (value - min) / (max - min)
The engine automatically detects if "Higher is Better" (e.g. HP) or "Lower is Better" (e.g. Price). If lower is better, the score is inverted (1 - score).
Finally, the engine applies your custom weights from the sliders. Each normalized score is multiplied by your weight, summed, and averaged to produce the final sort order.
