What Is 2017 Trans-Am Series

Overview

The 2017 Trans-Am Series celebrated a major milestone—the 50th anniversary of one of America's oldest and most iconic road racing series. Originally launched in 1967, Trans-Am returned in 2017 with a modernized structure while honoring its heritage of muscle car competition.

The season emphasized close, production-based racing across multiple classes, drawing teams and drivers from across North America. With events held at renowned circuits such as Road Atlanta, Watkins Glen, and Laguna Seca, the series offered high-speed action and technical challenges.

• TA class featured heavily modified V8-powered American coupes like the Ford Mustang and Chevrolet Camaro, producing over 700 horsepower.
• The XGT class included high-performance grand tourers such as the Porsche 911 GT3 and Dodge Viper, modified for track endurance.
• SGT class was designed for slightly less modified sports cars, including the Chevrolet Corvette and BMW M6, with strict balance-of-performance rules.
• The GT class catered to amateur drivers, using production-based vehicles like the Ford Mustang GT and Dodge Challenger SRT.
• TA2 class became the most popular category, featuring spec Chevrolet Camaro race cars with sealed 470-horsepower engines to ensure fair competition.

How It Works

The Trans-Am Series operates on a multi-class racing format, where different vehicle types compete simultaneously but are scored separately based on class performance. Each race weekend includes practice, qualifying, and a 100-mile or 100-minute main event.

• TA Class: The premier division features tube-frame race cars with bodywork resembling production models. These cars produce over 700 horsepower and are built to Trans-Am-specific technical regulations.
• XGT Class: Reserved for high-performance exotic cars like the Porsche 911 GT3 and Dodge Viper, these vehicles undergo safety and aerodynamic modifications but retain factory engines.
• SGT Class: Designed for advanced amateur teams, this class includes modified versions of the BMW M6, Chevrolet Corvette, and Audi R8 with power outputs around 600 horsepower.
• GT Class: Entry-level for drivers using near-stock versions of the Ford Mustang GT and Dodge Challenger, with safety gear and minor performance upgrades allowed.
• TA2 Class: The most competitive class, featuring identical Chevrolet Camaros with sealed 7.0L V8s producing 470 horsepower, ensuring close racing through technical parity.
• Scoring System: Points are awarded based on finishing position within each class, with bonuses for pole position and leading laps, following SCCA-style regulations.
