The decision to can Subaru’s WRC programme was taken in Japan on Saturday evening (13 December) - just days after the team’s entry for the 2009 WRC series was submitted to the FIA.
The decision was taken by Subaru’s parent company, Fuji Heavy Industries (FHI), partly as a result of the economic downturn but also because it was felt Subaru had achieved its sporting and marketing objectives.
At a press conference in Tokyo this morning the president of FHI, Mr Ikuo Mori, underlined the reasons for the withdrawal, saying: “We have achieved our initial objective to improve the brand recognition. And also given the unprecedented economic situation deterioration, it was necessary to review our investments. These are the main reasons.”
Mori said there was a desire within FHI to see Subaru back in the WRC but this was unlikely to happen in the short term. “If we can be allowed, we want to continue - especially for the fans,” he said. “The possibility of a Subaru car back in the top category of WRC in the future is not zero, however for this moment there can be no assumption of a comeback.
“Reaching the decision has been an extremely difficult task, not least because of the countless Subaru fans that have supported our cars for so many years. We would like to express our sincere appreciation for our fans' strong and loyal support worldwide. They will remain an invaluable treasure for us,” he added.
Mori denied that alterations to the WRC technical regulations in 2010 or a rumoured deterioration in the working relationship with Prodrive had any impact on the decision. Prodrive representatives flew to Japan this morning to begin the process of winding up the contract, which was due to expire at the end of 2009.
A statement issued today by FHI read: “FHI has participated in the WRC together with Prodrive over the past 19 years to pursue its goal and philosophy in motor sports activities to enhance Subaru brand awareness by showing that Subaru vehicles offer safe, comfortable and pleasurable driving no matter the weather or road conditions, featuring Horizontally-Opposed engine and the Symmetrical All-Wheel drive system as its core technologies, and to transfer results of race-tested technical improvements into Subaru passenger vehicles.
“FHI considers it has achieved its original target in WRC participation. However, while considering positioning the WRC activity in Subaru branding strategy towards the future, our business environment has been dramatically changed due to the quick deterioration of the global economy. In order to optimize the management resources and to strengthen further the Subaru brand, FHI decided to withdraw from WRC activities at the earliest timing.”
