The trade-off was that the luggage space under the coach was largely eliminated, but few public transit operators used that space in normal operation. MCI named the coach the D45 CRT LE for commuter rapid transit, low entry. Because of the extensive changes necessary to the coach, MCI used the development of the D45 CRT LE as an opportunity to develop a second generation of the D-Series coach with new styling and updated systems and components. Those updates began appearing on high-floor coach models beginning in 2020.

Between 2020 and 2022, MCI began to replace more of Legacy models with new models based on the D45 CRT LE. The D45 CRT, a transit coach similar to the D45 CRT LE but with a traditional wheelchair lift instead of the low entry section, the D4520, an intercity coach designed to replace the D4505 and

To address these problems, in 2017, MCI debuted a new version of the D-Series with a low-floor area in the middle of the coach. This area allows passengers using wheelchairs to board much faster than using a ramp, and provides a second door to allow passengers to board and alight at the same time.

Several changes in the industry in the late 1980s and early 1990s led to the development of the D-Series coach. First, was the growing calls to allow 45-foot (14 m) coaches (at the time prohibited by US law), second was that MCI's existing models were designed to use

MCI developed two prototypes to test the various proposed changes. In 1989, the company stretched an existing 102-C3 model to 45 feet (14 m) and in May 1990, in partnership with the
Canadian government, MCI built a wheelchair accessible bus with a

The D-Series was introduced in
February 1992 as MCI's first 45-foot (14 m) motorcoach, enabled by a December 1991 law change that allowed the additional length. The coach replaced the B- and C-Series models, which were equipped with obsolete
