Chronology

The MCI 102DL3 and MCI D4500 are identical intercity bus models manufactured by Motor Coach Industries at their plant in Pembina, North Dakota, United States. The 102DL3 was the original designation, used from 1992 through 2001, when the name was changed to D4500. It was the first successful 45 foot coach in service and is among the most popular intercity coaches in North America. The coach uses MCI's special platform integral construction, which has come to dominate the US and Canada markets, allowing high durability and easy maintenance. It has a much longer service life than body-on-chassis coaches. All 102DL3 and D4500 coaches are equipped with diesel engines and are available with full-painted sides or stainless steel lower body.

The MCI 102DL3 was developed from a 1988 Canadian government request to develop a wheelchair-accessible intercity bus. The prototype was apparently developed from the MCI 102C3 with a 102B3 nose and extended to 45 feet 5 inches (13.84 m). A large wheelchair-accessible lavatory was installed in the rear. The prototype was completed in 1990, but couldn't enter service in the US because it was too long, until the 45-foot length was approved in 1991.

Changes were made for the production model. The engine was upgraded to the large new Detroit Diesel Series 60 and received a bigger rear end with powerful radiator and intercooler. The large lavatory and wheelchair lift was removed from the production model, but could still be fitted by request. In the future a lift would be required for ADA regulations.

The production model was named 102DL3 and entered production in October 1992, followed by introduction into service in 1993. Early buyers included Peter Pan Lines, Fullington Trailways, and Horizon Coach Lines. The bus was immediately known for its surprisingly high speed, large size, and the durability of the integral construction. At the time, Greyhound Canada owned MCI, so they tested the model in 1992, but didn't order any until 1995.
