The 2026 APC United Late Model presented by Castrol championship kicks off on May 9 at Delaware Speedway with a race called the Dayco 100. In late May, the teams make the first of two stops at Flamboro Speedway. In mid-June, the series travels to Peterborough Speedway. On the Canada Day weekend, drivers return to Delaware Speedway for the AC Delco 159. The next race sees the championship make its final appearance at Flamboro Speedway for the London Recreational Racing 125. The Stewart’s Kubota 175 is conducted in early August at Sauble Speedway. Teams return to Sauble for round seven, called the Stewart’s & Kubota 100. Titles are determined on September 26 at Delaware Speedway during the Castrol Great Canadian 300.

The series rules remain basically unchanged from last season. Cars are built to specifications and controls typical of most stock car series. The chassis uses a tube frame with an ABC/Gen 6 body, available as a Chevrolet Camaro, Chevrolet SS, Ford Mustang, Toyota Camry, or Dodge Charger Daytona.

Depending on the engine choice, a car can weigh up to 2,780 lbs. Competitors are required to use crate motors from:

• General Motors GM 604 (Red & Blue Sealed)
• General Motors GM 602
• Ford 347

All engines must be fitted with five seals to prevent illegal alterations to the motor:

• Intake Manifold
• Oil Pan
• Timing Chain Cover
• Left Cylinder Head
• Right Cylinder Head

Competitors use American Racer spec tires on 15"x10" steel rims.

Stopping the cars are steel brakes.

• Front brake rotors must be a minimum of 1.250-inch (1 ¼-inch) thick.
• Rear brake rotors must be a minimum of 0.750-inch (¾-inch) thick.

Bilstein A2 shock absorbers are used to regulate expenses. There are also rules restricting the options for transmissions, ignition components, etc.

To determine the starting order of the race, drivers participate in a qualifying session. The five fastest qualifiers selected starting positions one through five during a random draw. Before each race, the cars receive a technical inspection and are impounded until the start of the event.

A new restart procedure was introduced in 2023 by series officials for the APC United Late Model and Dayco Super Stock divisions called the 'choose rule.' On restarts, competitors may choose their lane. Their selection may be determined by the condition of the track, how many cars are ahead of them, or the handling of their vehicle. If a driver changes their choice after the designated 'choose spot,' they must start from the rear of the field.

The 2026 NTN BCA Bearings Triple Crown returns for the fourth straight year. The three dates for the Triple Crown are Peterborough Speedway on June 13th, Sauble Speedway on August 1st and Delaware Speedway on September 26th. The three-race mini-series has a $15,000 prize fund. First place pays $3,500, second place $2,500, third place $2,000, and fourth through tenth place $1,000.

In 2026, the series introduced a new program for APC United Late Model racers. The Elite Program recognizes teams that commit to competing full-time in the APC Series season and offers extra incentives and benefits.

Round three of the APC United Late Model championship was held at ‘Canada’s Toughest 1/3 Mile Oval,’ Peterborough Speedway. This was also the first contest in the NTN BCA Bearings Triple Crown. Drivers competed in a 175-lap contest.
