The Mansells spent the first day shaking down the car and working with the Beechdean Mansell Motorsport engineers to find a set-up all three drivers could work with. Nigel spent the majority of the first day behind the wheel, before handing over to Leo. Greg completed the day's running in wet conditions.
Leo and Greg shared the majority of the driving duties on day two, before their 1992 Formula 1 world champion father completed a few laps of dry running in the afternoon. The majority of the test, during which Le Mans Series race-winning squad ORECA also appeared, was affected by torrential rain.
Nigel Mansell said: "It's truly brilliant when you can draw breath and say that the test has surpassed every expectation.
"The Zytek-powered car worked pretty flawlessly; I'm so proud of Leo and Greg, the times they got down to in a very short window were very competitive.
"To gel a team in just three and a half months is fantastic and while we know we have a huge challenge ahead, we are so pleased with what has been accomplished here."
