GB&I, which has won the last five Seve Trophy events, took four of the five fourball matches Friday at the Saint-Nom-La-Breteche course in Paris.
Simon Dyson and Jamie Donaldson defeated Miguel Angel Jimenez and Pablo Larrazabal 2-and-1 in the day's first match while Darren Clark and David Horsey finished 1-up on Nicolas Colsaerts and Matteo Manassero.
The Seve Trophy is an every-other-year event pitting golfers from Great Britain and Ireland against a team of players from the European continent. It was first contested in 2000, which ended in Continental Europe's only victory.
It is named for Spanish golfing great Seve Ballesteros but this is the first competition since Ballesteros died.
