The group were treated to rain, hail, fog and even occasional sunshine as they worked on the brand-new car.
Three weeks after the very first outing, Citroën Racing continued progression of its 2017 Globe Rally auto in the south of Portugal. Faced along with a number of weather conditions, Kris Meeke and Stéphane Lefebvre racked up the miles throughout four days of testing.
After holding the very first test in the south of France, Citroën Racing headed for Portugal and the Algarve for the second session of progression testing for its 2017 Globe Rally Car. The group were treated to rain, hail, fog and even occasional sunshine as they worked on the brand-new car. Prior to contesting Rally de Portugal along with the Abu Dhabi Total Globe Rally Team, Kris Meeke/Paul Nagle and Stéphane Lefebvre/Gabin Moreau were busy behind the wheel of the prototype made by the Versailles Technical Centre.
It was a important moment due to the fact that some components took a long time to manufacture.
“We were actually fairly pleased to have actually these variable conditions due to the fact that they meant we could test various set-ups and assess exactly how the bodywork stood up to being loaded along with mud,” explained Laurent Fregosi, Citroën Racing’s Technical Director. “throughout the tests, we have actually several objectives. Obviously, we hope to inspect the reliability of the various components. The mileage done by each portion is noted down to guarantee it tallies along with the specifications. However our job is likewise focussed on looking for performance and driver comfort.”
After graduating in Engineering at INSA Lyon, Laurent Fregosi joined Citroën Racing in 1995, as soon as the ZX Grand Raid dominated the Dakar Rally. He has actually therefore worked on every rally programme because the Xsara Kit-Car. Appointed Chief Engineer, Chassis, in 2005, Laurent took over from Xavier Mestelan-Pinon at the begin of the year. Involved for over a year on the 2017 programme, the brand-new Technical Director reflected on the origins of the car.
“Seeing our Globe Rally auto finish two long test sessions on demanding surfaces devoid of encountering any sort of serious troubles is rather delightful and merely benefits for those that have actually been functioning on this project for over a year,” emphasized Laurent Fregosi. “As always, we began by drawing up a set of specifications, based on the FIA regulations and the Brand’s marketing goals. Once we had selected the base model, we retrieved the CAD data in order to define the layout of the main components: engine, transmission, fuel tank, spare wheel, etc. The design of the roll cage stemmed from all of these volumes also as the regulatory placement of the crew.”
Called on to develop the very first drawings, the design office after that went to job on designing each part: “The approach is constantly the same: design hard-wearing, light components, whilst implicitly looking to adjust and reduced the centre of gravity. The crews, also as the engineers and technicians that will certainly be operating the car, were asked to offer their opinion. We still need, for example, to boost the removal of portions that are most likely to be replaced in service.”
“As ever, the job done factored in the experience acquired over the last twenty years or so at the highest degree of Globe rallying. However we likewise added to our knowledge base by completing examinations along with a DS 3 WRC progression mule,” revealed Laurent Fregosi. “Having reasonable the rate of its progression in 2014, we wanted to attempt out a couple of brand-new solutions for the future. We used a Citroën C-Elysée WTCC engine, which meant the auto immediately possessed the very same electricity degree as we’ll see next year. We likewise tested the most recent suspension systems.”
Once approved by the Computation Design Office, the drawings were handed over to the various workshops (transmission, suspension-steering-brakes, electronics, plastic components, etc.) to manufacture the portions then match the sub-assemblies.
Packed in to much less compared to a month, the assembly of the very first prototype involved the efforts of various teams: “It was a important moment due to the fact that some components took a long time to manufacture. In the workshops, the technicians adopted a just-in-time approach, so that we would certainly be all set on schedule. Even though we have actually already completed two test sessions, we’ve only merely begun the journey.
Analysing the data and driver feedback helps us to make the technical definition whilst deciding on the most efficient solutions. As the very same time, we are likewise preparation a second car, which will certainly be shortly used for testing on tarmac. This iterative means of functioning – which affects all of areas, from the chassis to the engine, including the transmission and the aerodynamics – will certainly keep on until we should obtain homologation of the auto for the 2017 Rallye Monte-Carlo. That point appears so far away, and yet it’ll be here Prior to we understand it!”
