Mansells plan Petit Le Mans outing

He and elder son Leo set the quickest time of their first test of a Le Mans prototype at Estoril last week and Nigel says an all-Mansell line-up for the event at Road Atlanta in October is a possibility.

"It's all down to finance," he said. "There are a lot of opportunities, but we will have to sit down and see what support is available for what programme."

Atlantic Championship racer Leo, 23, set a fastest lap of 1:27.9 at Estoril, in Chamberlain Synergy's Lola-AER B06/10. Former world champion Nigel's best effort was just a tenth slower, equalling the time set by Jamie Campbell-Walter in the Creation-AIM CA07.

"This shows there's life in the old dog yet," said Mansell Sr, 54. "I'm also thrilled with Leo's speed. I never dreamed that we would be competitive straight out of the box.

"This has brought back some fantastic memories for me. These prototypes remind me of Formula One cars of the late 80s and early 90s."

Mansell's younger son, Greg, was also present at Estoril but did not drive because he is still recovering from a concussion he sustained in an Atlantic crash at Mont-Tremblant last month.
