other International product lines, the 9370 was renamed the International 9300. For the first time, a set-back front axle configuration was offered. For 1990 the 9400 was introduced as the first aerodynamic conventional from International, using a set-back front axle and a sloped hood. While less radical than the Ford Aeromax or the Kenworth T600, the 9400 offered skirted fuel tanks as an option. In 1993, the 9200 was introduced (a shorter-hood version of the 9400); the set-back axle version of the 9300 was dropped. In 1992 the luxuriously appointed 9400 Midnight Eagle Limited Edition was introduced; offered only with the Caterpillar 3406 diesel engine it had a leather interior with wood trim and a fully color-coordinated exterior. In 1997, the 9100 was introduced; produced largely as a daycab. For 1997, International gave the 9000-series (outside of the 9300) a mid-cycle update, with a redesign of the grille, front bumper, and headlight surrounds. For 1999, the 9300 (derived from the 1971 Transtar 4300) was replaced by the 9900, pairing a squared-off long hood design with headlights faired into the fenders. Third generation (i-series; 2000-2017) Previewed by the 1997 update to the 9000 series and the 9900, for 2000, the International heavy truck range underwent their most extensive redesign since 1971. While sharing its underlying aluminum structure, the firewall of the cab was moved forward (enlarging the drivers compartment). In place of the previous two-pane flat glass, a single-piece curved windshield was fitted, along with cowl-mounted wipers. To improve outward visibility, the cowl was lowered (along with the lower half of the door windows); vent windows were deleted. The third-generation 9000 series was denoted with an "i" suffix; as with its predecessor, it shared its cab with the Paystar severe-service trucks (renamed the Paystar 5000i). The model line consisted of the 9100i (112-inch BBC), 9200i (112-inch BBC), 9400i (120-inch BBC), 9900i (120-inch BBC), and 9900ix (130-inch BBC). Sold primarily for regional use, the 9100i was offered only as a daycab (no sleeper). In contrast to the rest of the sloped-hood model line, the 9900i and 9900ix were configured with straight hoods, and the 9900ix was offered only with premium Eagle trim. During the 2000s and early 2010s, International began to pare down the models of the 9000 series in favor of newer designs based on the NGV cab. After the 2002 model year, the 9100i was dropped (effectively replaced by the
