MANNOL is stepping up its motorsport presence in 2026. After a successful run in the GT Winter Series and its confirmed campaign in the GT World Challenge Europe, the MANNOL Mercedes?AMG GT3 from Grupo Prom Racing will also join the International GT Open this season.

The lubricant brand is deepening its collaboration with the Mexican team by adding another high?profile European racing series to its portfolio.
The International GT Open is a strategic fit for MANNOL’s growth in Europe. The series runs on well?known circuits across several key markets where the company has been steadily expanding, giving MANNOL strong visibility in exactly the regions it wants to reach.
Beyond global brand exposure, the program also helps support local sales partners in their day?to?day business.
For years, MANNOL has used motorsport to test and showcase its lubricant technologies in real?world racing conditions. The International GT Open adds another competitive environment where its products can be pushed to the limit and proven.
The 2026 calendar features eight race events, with two 500?kilometre endurance rounds at Spa and Monza, and the remaining race weekends made up of two sprint races each.
The MANNOL?liveried Mercedes?AMG GT3, car number #77, will line up in both sprint and endurance formats. The primary driver will be Alfredo Hernández (MEX), with Stéphane Tribaudini (FRA) joining him for the endurance races.
Pre?season preparations kick off with official testing at the Circuit de Barcelona?Catalunya on 20–21 March. The season launches at Portimão from 17–19 April, followed by a trip to Germany at the Hockenheimring from 11–13 September, before the series concludes in Barcelona from 23–25 October.
