As in the previous year, there were three Touring groups:

• Touring Car (TC) – This class is for smaller sedans and sports cars which are allowed some performance modifications. These front or rear-wheel-drive vehicles may be powered by turbocharged or normally aspirated engines. Examples of cars competing in this category include: Honda Civic Type R, Nissan 370Z, BMW M235iR, BMW M240iR and Genesis Coupe.
• Touring Car A (TCA) – Some of the cars competing in this class are the same as those found in Touring Car. What sets them apart is the minimum amount of modifications that can be made – most changes are to improve the safety of the vehicles. Using turbocharged or normally aspirated power plants, these cars produce between 160 and 185-horsepower.
• Touring Car Race (TCR) – This is an international class which was first introduced in 2014 to address the expense of competing in the World Touring Car Championship. These production-based cars are powered by 2.0-liter turbocharged engines which produce approximately 300-horsepower. Examples of vehicles competing in this category include: Audi RS 3 LMS, Volkswagen Golf GTI TCR, Honda Civic Type-R TCR, Alfa Romeo Giulietta TCR and Hyundai Veloster N TCR. This category has been split into two groups – TCR and TCR Cup. The Cup division was added for gentleman and amateur drivers and cars equipped with a DSG transmission. TCR is for FIA rated Gold, Silver and Bronze drivers.

The TCR and TCA title chases kick off in March at Circuit of the Americas followed a week later by an event at St. Petersburg, Florida. The teams will not participate until late April at Virginia International Raceway. This will be followed by the west coast swing when race weekends will take place at Sonoma Raceway and Portland International Raceway. On the Labour Day weekend, drivers will compete at Watkins Glen International. The penultimate round will be held mid-September at Road America and the finale will take place at the Las Vegas Motor Speedway in October.

TC competitors also begin their season at Circuit of the Americas but do not compete again until late April at Virginia International Raceway. The remainder of the schedule is the same as the TCR and TCA classes. Teams will travel to California and Oregon for races at Sonoma Raceway and Portland International Raceway. Then it is back to the east coast for a weekend at Watkins Glen International. The penultimate events will be at Road America with the championships concluding at Las Vegas Motor Speedway.

The opening rounds for the 2019 TC America championship for Touring Cars took place at the Circuit of the Americas’ twenty-turn 3.4-mile road course. Seventeen drivers were entered in two forty-minute races.
