The former Sauber and Manor Formula 1 racer took part in a multi-day endurance test with the Porsche Penske Motorsport team at Sebring, Motorsport.com has learned.
News of the try-out comes at a time when it appears that Porsche still has a vacant seat in its planned 10-driver line-up across the Penske-run factory team’s twin assaults on the FIA World Endurance Championship and the IMSA WeatherTech SportsCar Championship next year.
