In 2008, BC Transit and Ottawa's OC Transpo issued a Requested for Proposal for heavy-duty, mid-size buses from the major bus manufacturers. These companies either had no interest in producing such a bus or did not have capacity. As a result, Grande West was founded that same year, led by businessman William Trainer. The company built key partnerships with BC Transit and tailored their proposed bus designs to the agency's needs. Grande West worked closely with management and engineers with BC Transit to understand requirements and specifications of the Vicinity. The company initially targeted the niche demand for green, compact buses in the North American market with their 27.5 foot bus. In October 2011, BC Transit placed an initial order for 15 Vicinity-model buses valued at $3.8 million. The first Vicinity buses were delivered on August 30, 2013 While the buses were designed by Grande West, they were manufactured in Yangzhou, China by Yaxing Motor Coach. Grande West went public with the initial public offering at the end of 2013. In 2015, Grande West entered a non-binding letter of intent with Weichai Power to explore the possibilities of mutual bus development under the Weichai Group. The objective is to increase sales and distribution in North America. At the time of the LOI, Weichai Group was already part of the manufacturing process as they provided assemblies and the uni-body frame. Final assembly is located in Aldergrove. The Vicinity buses meet theBuy America requirements in the United States allowing the sales of buses to government public transit agencies. This allows Alliance Bus Group, the exclusive distributor for the US, to bid on all public transit projects in the United States. The deal with Alliance Bus Group was finalized in May 2015 with the first orders placed four months later for 50 30-foot buses. Along with the Buy America requirements, the Vicinity 30 foot model passed the Altoona Testing Program in Altoona, Pennsylvania. All new bus models used for mass transitrevenue service and purchased with Federal Transit Administration funds must complete an Altoona Test.
