The MCI 102D3 and MCI D4000 are identical 40-foot Motor Coach Industriesintercity bus models. Among the most popular coaches in North America, they're manufactured in Pembina, North Dakota, United States. MCI introduced the 102D3 in 1994 to replace the 102B3 and 102C3 models, equipped with obsolete two-stroke engines. The 102D3 was the original designation, used from 1994 through 2001, when MCI changed its name to D4000. The coach uses MCI's 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 102D3 and D4000 coaches are equipped with diesel engines and are available with full-painted sides or stainless steellower body.
Development
MCI developed the 102D3 from earlier 102B3 and 102C3 coaches, which had engine compartment too small to fit the new Detroit Diesel Series 60 engines. These four-stroke engines also powered the larger 102DL3 coaches. MCI added an optional wheelchair lift. In the future a lift would be mandatory under ADA regulations. The 102D3 entered production January 1992, followed by introduction into service with Royal Blue Tours, Chameleon Express, Lemi Tours, Gulf Transportation, and Indian Trails. Later the same year, it entered service with Peoria Charter Coach Company, Eyre Bus Service, Kerrville Bus Company, Greyhound's Texas, New Mexico, and Oklahoma Coaches division, and Trailways of New York. Like its larger sibling the 102DL3, the 102D3 was immediately known for its high speed and the durability of its integral construction, albeit at a smaller size than the 102DL3. Greyhound Canada, which had owned MCI during the development process, introduced the 102D3 in 1995.
