We’ve already seen pictures of Oreca’s new 05 LMP2 coupe and now the car is out and testing ahead of its first public appearances at the ELMS and FIA WEC tests at Paul Ricard later this month.
The first completed car, the chassis bound for KCMG’s FIA WEC programme, turned its first laps at Paul Ricard yesterday, Stephane Sarrazin taking the wheel for the first track action, with testing currently due to continue both today and tomorrow with initial results reported as being very promising.
Having reviewed all of the different settings, the afternoon was then dedicated to a specific work on aerodynamics.
There were no mechanical problems which gave the engineers and mechanics a very productive session.
“It’s a solid car, I very quickly felt comfortable at its wheel” explained Stéphane Sarrazin. “The car has a consistent behaviour and is easy to get familiar with. It’s very agile in the sinuous sections : it’s nice for a driver to have a car that is so reactive. The ORECA 05 has an impressive finish. All of ORECA’s experience is there, particularly in the way everything was thought out. Technically speaking we did not have a single issue ; that allowed us to work well. The car is now born, that’s for sure. It’s always a nice thing to be involved in the first laps of a new prototype. I enjoyed it so much.”
The new Oreca is 1900 mm wide, as opposed to most of the current LM P2 which are 2000mm wide, twith other work having been undertaken in the design stage on weight distribution.
“The ORECA 05’s first test day is a positive one” says David Floury, ORECA’s Technical Director. “We went through the entire programme and the session was enriching. The contribution of a driver like Stéphane Sarrazin is very appreciated. His positive feedback is comforting in terms of the decisions we made both technically and regarding ergonomics. Of course there’re always some details here and there to sort out, but what we’ve witnessed throughout this first shakedown bodes well. The ORECA 05 has already demonstrated the qualities that we were expecting. We now have to refine all of that, collaborating with our customer-teams. Actually KCMG and ORECA worked hand-in-hand on that first day. That’s a way to strengthen our relationship and work more efficiently. It’s very important to us. Generally speaking we’re very happy to see ORECA’s new prototype take to the track for the first time. The car’s finish and the quality of those first tests show the progress we’ve made since the ORECA 01 and ORECA 03. We’re continuing on improving at all levels as a manufacturer.”
Assembly of the second chassis, to be entered by Thiriet by TDS Racing, is under way.
