The preview

The new 992-generation 911 GT3 Cup makes its racing debut in Porsche’s international one-make cup on the famous street circuit of Monaco. This year’s Porsche Mobil 1 Supercup, now heading into what will be its 29th season, includes eight races run as support to the FIA Formula One World Championship. For the first time, the car’s ca. 375 kW (510 hp) four-litre naturally aspirated engine will run on Esso Renewable Racing Fuel, a blend of fuels predominantly made from renewable, bio-based components. The switch to eFuel, which is based on hydrogen produced using renewable electricity, is planned over the course of the 2022 season. The goal of the cooperation between Porsche and ExxonMobil, who make the e-fuel, is to gain valuable experience in finding pathways towards potential future consumer adoption.

“The Porsche Mobil 1 Supercup heads into the 2021 season with two highlights. We start the season in Monaco for the first time. Given that we aren’t allowed to test on this very special racetrack and the fact that it leaves no room for mistakes is a huge test for the new Porsche 911 GT3 Cup. Plus, this is the first time we’re using the new Esso Renewable Racing Fuel from our partner ExxonMobil. The teams and drivers are super excited. In terms of lap times, the field is extremely close, which was underlined at the tests in Monza, Italy. I think we’ll witness the most gripping season-opener in Supercup history,” says Oliver Schwab, Project Manager Porsche Mobil 1 Supercup.

Larry ten Voorde (Netherlands, Team GP Elite) tackles the Monaco round as the reigning champion. His rivals include last year’s vice-champion Dylan Pereira (Luxembourg) and Porsche Junior Ayhancan Güven (Turkey, both BWT Lechner Racing) as well as the title defenders of the rookie and ProAm classes, Max van Splunteren (Netherlands, Team GP Elite) and Roar Lindland (Norway, Nebulus Racing by Huber). Joining the newcomers is 20-year-old Harry King (Great Britain, Parker Revs Racing), who receives support from Porsche GB as the reigning champion of the Porsche Carrera Cup Great Britain.

Porsche and ExxonMobil are implementing a two-stage strategy in the introduction of renewable fuels in the Porsche Mobil 1 Supercup. This season, the racing vehicles will be powered by a blend of advanced bio-based fuel obtained from food waste products. Additional components are blended in to enable the required fuel properties and combustion behaviour. In 2022, the next step will be to introduce eFuel synthetically manufactured in the Haru Oni pilot facility in Chile. This Esso Renewable Racing Fuel is anticipated to reduce greenhouse gas emissions by up to 85 per cent, when blended to current market fuel standards for today’s passenger vehicles.

The season opening round of the Porsche Mobil 1 Supercup takes off on Sunday (23 May 2021) at 10:20 CEST. Eurosport and Sky Sport along with the streaming service will provide live broadcasts. Fans can also follow the Porsche Mobil 1 Supercup action on TwitterInstagram and Facebook.
