Oliver Jarvis will make his full World Series by Renault debut this weekend, having received a last-minute call-up from the Carlin Motorsport-affiliated Victory Engineering squad.

The Briton tested a World Series car last winter after winning the UK Formula Renault title, but opted for a year of Formula Three with Carlin instead of taking too big a step up the ladder. Having finished as runner-up to Mike Conway in the British series, however, the reigning McLaren Autosport BRDC Young Driver of the Year will make his WSbR debut in the season finale at Barcelona's Circuit de Catalunya.

The 22-year old, who tested with the Interwetten.com and KTR teams at Paul Ricard last December, replaces Victory regular Hayanari Shimoda, who was unavailable to drive at the season finale.

"This weekend will be a steep learning curve for Oliver, as it will be his first outing for a while in a World Series Car and first ever at Barcelona," team manager David Lowe admitted, "Obviously, it is great experience for him, and the main aim will be for him to learn about the car and the circuit."

Jarvis isn't the only alteration to an already much-changed WS entry this weekend, however, with Eurointernational again taking eth opportunity to tinker with its line-up, bringing in Spanish F3 regular Nil Monserrat in place of Britain's Richard Keen, who stepped down from the ride at the last minute. Monserrat, a relative unknown to most race fans outside of Spain, will become the tam's tenth different driver this season when he lines up alongside British F3 point-scorer Alberto Valerio.
