The 2017 D45 CRT LE added a low-floor section mid-coach for faster wheelchair boarding, plus a second door so passengers can board and alight at once.

The D-Series debuted in February 1992 as MCI's first 45-foot motorcoach, enabled by a December 1991 law change that allowed the extra length.
Rivals
Same body, same money, other badges — tap any card to flip.

The H3-40 followed the articulated H5-60 in 1989 as a 40-foot rigid-body H-Series coach.

A widely used Prevost coach built 2002-2009 in the thousands; about 5,500 remain on North American roads (estimate). About 5,500 on North American roads today (estimate).

Prevost's best-selling generation, built 14 years for coach lines and conversions; around 7,500 in North America (estimate). About 7,500 on North American roads today (estimate).

Prevost released the H3-45 in 1994, after 45-foot buses were legalized.

With the 2023 update of the Prevost H3-45, the shorter H3-41 was discontinued, leaving the H3-45 as the only H-Series bus in production.

A 1960s-70s intercity coach with a few thousand built; very few survive unconverted, so about 150 are left (estimate). About 150 on North American roads today (estimate).

The CX45 was introduced in 2013 for the 2014 model year as a redesigned C2045, and a 35-foot CX35 followed in 2015 to compete with the MCI J3500.

Many MCI coaches like the MC-9 survived millions of miles of commercial use and went on to second careers with churches, or as motorhome conversion shells.
