In 2003 MMAL gained approval from MMC to create Mitsubishi Research and Development Australia (MRDAus) with a budget of $30 million. MRDAus was to be the fourth global Mitsubishi Research and Development Centre. MMAL's proving ground at Tailem Bend was to be upgraded including the addition of a high speed oval and numerous other proving ground facilities and the Testing and Proving group's laboratories at MMAL headquarters in Tonsley Park was also to be upgraded. MRDAus was originally tasked with completing Mitsubishi 380 Testing and Proving prior to the start of volume production. MRDAus also negotiated substantial job share for the testing and proving of the PS41L, the codename for a stretched 380 for the US market. Unfortunately with the financial woes facing MMC globally and the cancelling of the PS41L program MRDAus was unable to reach its full potential. In late 2004 after expanding to 90 personnel the MRDAus expansion was halted before the 380 was even launched. A security fence around most of the expanded Tailem Bend site was almost completed and the earthworks for the high speed oval had begun when work was halted in 2004.
