The new low entry project includes designs for a 32.5-foot, 35-foot, 40-foot and 42.5-foot low floor bus utilizing a T-drive engine configuration. The RTS Extreme design incorporates a similar design philosophy as the RTS Legend, using a welded, modular stainless steel body construction. The major objectives of the new bus design are to meet customer requirements including a more conventional rear centered T-drive engine offering, at a lower cost than comparable competitive products and provide larger engines, no rear facing seats and an increase in passenger seating capacity. The RTS Extreme is a standard rear drive high floor with a lowered middle and front section of the bus. This lowered area allows the benefits of the low floor entry and exit, but also the standard driveline equipment. Management is utilizing a product development program that incorporates a gate approval process.

The program involves stages where prototypes are designed and built and preliminary performance tests are conducted on the durability test track and on select customer routes. Customer feedback sessions will be held and market surveys conducted to ensure key customer acceptance and retention for the new product. The project includes review of documentation and testing data, vendor involvement startup, testing completion, production documentation development, quality standards, prototype builds and final reviews. Millennium Transit's strategy is to partner with a valued customer for the final testing and approval of the design.
