Although their A1 Grand Prix relationship has come to an agreed end, Carlin Motorsport and Hayanari Shimoda could yet continue working together in 2006.

Carlin was responsible for the A1 Team Japan entry that Shimoda campaigned on three occasions - including the infamous Eastern Creek round which saw the sportscar ace roll the white Lola to destruction - but has since parted company with the driver, as well as putting its A1GP involvement on hold pending the arrival of a replacement.

The parting was amicable, with Shimoda only being contracted for three races, and Carlin team boss Malcolm Swetnam has made no secret of the desire to work together again in future.

"Our deal with Hayanari was only for three races, and he honoured that at the Dubai A1GP round in December," Swetnam confirmed to the official A1GP website. "We may well be involved with Hayanari again later this year, though, as his run in A1GP fired him up to race single-seaters again and he's looking at racing in GP2 or possibly with us in the World Series by Renault."

Any link up between the two parties would appear to be confined to the World Series as, despite rumours of an impending buy-out of an existing entry, Carlin saw its hopes of joining the GP2 Series quashed. The British squad will continue to run two cars in the WS, however, following a race-winning campaign with Will Power and Andy Zuber in 2005.

Shimoda has already tested GP2 machinery this winter, just as he did ahead of the 2005 season, when he narrowly failed to land a ride at Super Nova.
