The Stock Car Chevrolet Tracker will make its first appearance amid the activations of the sixth round of the Stock Car Pro Series, which takes place at the Autódromo Internacional de Goiânia Ayrton Senna, on the 27th and 28th of July. It is the first of three SUVs, from different manufacturers, to be shown. They will take over the Stock Car grid from next year onwards.

The newest Stock Car will be one of the weekend's attractions and will act as a pace-car, leading the grid at Goiânia before the start, in addition to being the protagonist of activations on the track. Days later, the car will be on display and will take to the track during the Interlagos Festival, an event of motor experiences and exhibitions, which will be held between August 9th and 11th at the most famous racetrack in Brazil.

The big news for 2025 in Stock Car is that SUVs will replace sedans after 45 years of history. In the Chevrolet family, the Tracker Stock Car succeeds the competitive Cruze, after eight years and five titles, ending another cycle for the manufacturer, whose legacy on the track began in the inaugural race of the championship, back in 1979. A story that also includes Chevrolet models Opala, Omega, Vectra, Sonic and Astra.

More agile, stable and technological, the Chevrolet Tracker Stock Car is part of the Audace SNG01 project, which has ambitious goals for 2025. “This is an opportunity for us to present the full potential of this new platform, which was developed with advanced engineering resources and suitable for competition, such as the movable carbon fiber wing and 5G connectivity. The purpose is to bring even more competitiveness to the drivers and excitement to the public”, explains Fernando Julianelli, CEO of Vicar, promoter of Stock Car.

According to Enzo Bortoleto, CEO of Audacetech, car manufacturer and technological arm of Veloci Group, Vicar's mother company, a new chapter of the South American motorsport is on the way, as there has never been a project like this in the region. “It took years of work and high investment, integrating different areas, nationalities and cutting-edge companies. From the beginning, with the development of ArcelorMittal special steel, to the incorporation of electronics, engine, gearbox, cockpit and safety systems.”

The Chevrolet Tracker Stock Car's rivals will be the competition versions of the Toyota Corolla Cross and Mitsubishi Eclipse Cross, which will be presented soon.

“The choice of Tracker as Chevrolet's representative in Stock Car is an innovation that reflects the consumer's desire for SUVs, a segment that has recently come to dominate the Brazilian market. Furthermore, the Tracker is the best-selling sports utility vehicle in South America and the competition reinforces the product's successful image”, says Chris Rego, Marketing Director at GM South America.

The sixth round of Stock Car Pro Series 2024 season takes place at the Autódromo de Goiânia, which this weekend celebrates 50 years since its inauguration. The races will start at 3:30 pm on Saturday and 2 pm on Sunday (local time).

Stock SUV brings new silhouette, platform and mechanics

Approved by the Brazilian Automobile Confederation, the new Stock Car 2025 cars were created by Audacetech in partnership with giant stell company ArcelorMittal, the Instituto de Pesquisas Tecnológicas (IPT, or Technological Research Institute) and Serviço Nacional da Indústria (SENAI, or National Industry Services), both acknowledged institutions in Brazil . The development used computer simulation from Siemens and the IPT. Manufactured by Brazilian company Magna Compósitos, the composite bodywork includes carbon fiber, aramid, fiberglass and kevlar. The engine is now turbocharged and 2.1 liters with approximately 500 hp of power, using Brazilian Petrobras Podium gasoline.

The XTrac competition gearbox is sequential and semi-automatic, with six speeds, and is one of the highlights alongside the connectivity provided by the Qualcomm Snapdragon 5G system, with sensing of various car functions. With adjustable shock absorbers imported from Penske Racing, the suspension is independent on all four wheels, equipped with double wishbones (“double A”) and uses a pushrod system. The set of wheels developed in Brazil by Mangels hides the HipperFreios ventilated discs, Cobreq pads (both designed specifically for the Stock Car) and competition calipers from the British AP Racing, operated by six pistons at the front and four at the rear.

Engine and suspension also use competition elements, produced by Brazilian MTR Performance Parts. Specially manufactured for the Stock Car, the steering wheel is from the Dutch company Grid Engineering. The sophisticated cockpit, with a monitor and panel equipped with dozens of functions, has an internal 360-degree camera, which should soon be used in race broadcasts and also in the exclusive mobile application that will be launched by the category.
