Porsche GT4 e-Performance test vehicle used to develop new ExxonMobil thermal management fluid
ExxonMobil has revealed a new Mobil 1 three-in-one thermal management fluid developed for all-electric racing. The company’s latest product has been engineered specifically for use by the Porsche GT4 e-Performance – a concept race car with a unique cooling system.
With a drivetrain capable of delivering a peak output of up to 800kW (1,104ps), the Porsche GT4 e-Performance is viewed as an important test vehicle for the future of all-electric racing. Its advanced direct oil cooling system counteracts thermal derating, ensuring the GT4 e-Performance can maintain constant power output in race mode for up to 30 minutes.
Equipped with 900V technology, the vehicle’s battery can be charged from 5-80% in 15 minutes. When used in a race scenario, the equipment places considerable stress on the Porsche’s thermal management system. This has been overcome through the collaborative development of the Mobil 1, three-in-one thermal management fluid.
“Our long-term collaboration with Porsche allows us to push boundaries, both in terms of combustion engine lubrication and fluids for emerging EV designs like the Porsche GT4 e-Performance,” said Tobias Klande, technology solution professional at ExxonMobil’s European Product Technology Centre (EPTC) in Hamburg. “This new Mobil 1 fluid shows how, together, we’re testing and developing new concepts under the toughest conditions to find e-mobility solutions for the commercial production of tomorrow.”
“We now have a single Mobil 1 thermal management fluid that we can use across all three components of the cooling system, helping to reduce overall system weight,” explained Rüdiger Klutinus, a Porsche HV engineer. “It helps optimize power delivery during acceleration and recuperation, extend battery life and enable faster charging during breaks to help increase track times. It also delivers enhanced e-motor durability and power electronics efficiency, providing sustained power for longer.”
