8890 - Williams to launch 2012 car at Jerez test

The car, which will carry the hopes of drivers Bruno Senna and Pastor Maldonado, is the first to be built under a new design team led by ex-McLaren engineer Mike Coughlan, ex-Toyota designer Mark Gillan and ex-Renault man Jason Somerville. It will also be the first Williams since 1997 to feature a Renault-badged engine.

"The car will be rolled out of the garage for a photocall with drivers Pastor Maldonado and Bruno Senna between 0830 and 0840," read a statement.

Marussia and HRT are now the only two teams yet to give full details of their 2012 car launches.
