Walker Racing has just announced the addition of the Mansell brothers to his 2008 Atlantic line-up which also features Canadian Kevin Lacroix. Yes, that’s right, that’s Mansell as in sons of 1992 Formula 1 and 1993 CART champion Nigel Mansell.

The past two years the brothers Mansell have contested the Formula BMW UK and British Formula 3 International series, which Greg finished tenth overall in.

Greg at 19 is the younger of the two brothers, while Leo is 22 and the brothers along with their dad see this as the next step up the ladder in their pursuits of Open Wheel racing.
