Porsche Sport Challenge is the largest amateur–professional racing series in Russia, founded by Oleg Kesselman.

Launched in 2011 as a competition for members of Porsche Club Russland, the series has grown into a national championship where anyone who dreams of racing can line up on the same starting grid with experienced drivers.

In 2015, Porsche Sport Challenge became a support race for the legendary Deutsche Tourenwagen Masters (DTM), marking an important milestone in the series’ development.

Since 2023, the series has been rebranded as GT CUP and opened its doors to GT4 cars from other manufacturers. The general partner of the championship is Sber Pervy Bank.

Each race weekend attracts up to 5,000 spectators and turns into a vibrant motorsport event — featuring thrilling races, racing simulators, mobile test drives and entertainment programs for the whole family.

The company’s extensive experience in motorsport allows it to successfully deliver events of any scale — from local races to international rally raids.

A striking example of such cooperation is the project with TANK Russia, which involved participation in the international Silk Way Rally in 2024 and 2025.

Kesselman Motorsport took full responsibility for the project, including vehicle preparation, logistics, driver training and on-event support for participants competing under the TANK brand.

The results speak for themselves: for two consecutive years, drivers in TANK 300 vehicles not only secured podium finishes but also claimed overall victories in the GRAND TOUR category, confirming the team’s high level of preparation and professionalism.

Together with Mazda Russia, Kesselman Motorsport launched a project of accessible amateur racing, open to virtually anyone interested in motorsport.

Qualifying rounds of the Zoom-Zoom Challenge were held in many cities across Russia in the format of car control competitions, with finalists advancing to races on professional racing circuits. Winners were awarded prize trips to legendary European tracks such as Nürburgring Nordschleife, Spa-Francorchamps and Zandvoort.

Over time, the Zoom-Zoom Challenge evolved into full-scale racing championships — first on identical, race-prepared Mazda MX-5 cars in the Mazda Sport Cup, and later into the winter racing series Mazda Ice Race.
