Overview

The 2006 Rolex Sports Car Series marked the seventh season of the Grand American Road Racing Association's top-tier sports car racing championship. Sponsored by Rolex, the series showcased high-performance prototypes and grand touring machines competing across North America in a mix of endurance and sprint events.

Organized by the Grand American Road Racing Association, the season featured two primary classes: Daytona Prototypes (DP) and Grand Touring (GT), each with distinct technical regulations and manufacturer involvement. The series emphasized driver skill, team coordination, and mechanical reliability over diverse track layouts and race lengths.

14 races were held from February to October, beginning with the 24 Hours of Daytona on February 4, 2006, a cornerstone event in endurance racing.
The Daytona Prototype class featured custom-built chassis from manufacturers like Riley, Dallara, and Pontiac, powered by engines up to 5.0L V8s.
The GT class included production-based vehicles such as the Porsche 911, Chevrolet Corvette, and Dodge Viper, modified for track performance.
Chip Ganassi Racing dominated the DP class, winning the championship with drivers Scott Pruett and Juan Pablo Montoya securing four victories.
Telcel/Alivod Racing clinched the GT title with Antonio García and Luis Díaz, accumulating consistent top-ten finishes across 12 appearances.

How It Works

The Rolex Sports Car Series operated under a dual-class racing format, combining prototype and GT vehicles on track simultaneously, with separate scoring and championships for each category.

Daytona Prototype (DP): Introduced in 2003, this class featured open-cockpit prototypes with production-based engines and custom chassis, limited to control tires and aerodynamic kits to ensure cost control and close racing.
Grand Touring (GT): Vehicles in this class were based on road-going models, with 500+ horsepower engines and extensive suspension and brake modifications for track use.
Race Duration: Events ranged from 45-minute sprints to 24-hour endurance marathons, requiring multiple drivers and pit strategy.
Driver Ratings: Competitors were classified as Platinum, Gold, or Bronze based on experience, influencing team composition and class balance.
Scoring System: Points were awarded based on finishing position, with 35 points for a win and bonuses for leading laps and class records.
Track Diversity: The series visited 11 circuits, including road courses like Laguna Seca and Watkins Glen, and street circuits like the Grand Prix of Miami.
