the FE/RE-Series transit-style buses). During the mid-2000s, IC began an overhaul of its product line. For 2005, the International 3300 was introduced as a cowled-chassis variant of the International 4000-series (DuraStar), becoming the first completely new cowled chassis from International since 1979. In 2006, IC produced its first small school bus, the 30-passenger BE200. In place of a cutaway van chassis, the BE adopted a lower-profile version of the 3300 chassis. Externally similar to the CE, the smaller BE was designed with a flat-floor interior. To comply with 2007 EPA emissions standards, IC buses adopted MaxxForce diesel engines for 2007, including the MaxxForce 7 6.4L V8 and the MaxxForce DT 7.6L I6. For 2008, to improve engine ventilation, the FE was given a wider grille, with the BE and CE adopting the redesigned front bumper of the International DuraStar. In April 2009, IC Corporation changed its name to IC Bus. Commercial bus production During its existence, the commercial product offerings of AmTran had been strictly derived from its school bus bodies, consisting as a small portion of its sales. In 2006, IC launched an expansion of its product range. Alongside the existing commercial derivatives of the BE, CE, and RE, the company introduced buses based on a cutaway-cab version of the International DuraStar. The HC was a range of shuttle buses; the LC was a paratransit bus with a low-floor configuration. 2010s For 2010, IC underwent an overhaul of its product line. The FE-series (which entered production in 1990 as the Ward Senator, later becoming the AmTran Genesis) was discontinued, leaving the RE as its sole transit-style bus offering. At the other end of the size spectrum, IC introduced two cutaway-cab buses derived from the International TerraStar truck. Slotted below the HC, the AC was a commercial shuttle bus, while the AE marked the first cutaway-cab school bus produced by the company. While using a smaller truck line for a donor chassis, the AE was offered in a higher seating capacity than the BE, up to 36 passengers. In a branding change, from 2010 onward, Navistar badged the International 3200 (the cutaway-cab version of the DuraStar) as an IC, regardless of body manufacturer. The IC "wing" logo was revised slightly in 2013 for 2014 production (with Navistar script added to the emblem and to the rear bumper).
