The International Newport Series is a series of cabover trucks that were produced by International Harvester and its corporate successor Navistar. Introduced in 1981 as the replacement for the Transtar II COE, the final Newport COEs for North America were built in 1998.

First generation (CO9670; 1981-1988)

For 1981, International Harvester introduced the CO9670 cabover to replace the Transtar II CO4070 in production since 1974. Sharing its doors with the Transtar 4300, the C09670 featured a wider cab, and larger windows and windshield. The trapezoidal grille used on all large International cabovers since 1965 was redesigned to include the headlights.

In place of the massive Cummins KT450 and Caterpillar 3408 engines included on the Transtar II, the CO9670 was powered by the smaller-displacement 855 cubic-inch N-Series Cummins diesel. In twin-turbocharged configuration, the engine produced 475 hp.

In 1989, Navistar updated the CO9670, rebranding it the International 9600.

Second generation (9700/9800; 1988-1998)

For 1988, Navistar redesigned the Newport-Series cabovers, allowing for the addition of a set-back front axle version. Although visually similar to the 9600 from the axles above, the 9700 was given many aerodynamic enhancements, including lower body skirting, an enhanced front bumper, and faired-in front turn signals. The front-axle configuration allowed for a complete redesign of the interior, allowing for a completely flat floor; Navistar was the first American manufacturer to market a cabover truck without an intrusion from the engine separating the driver and passenger seats, allowing walk-in access to the sleeper compartment. As an option, Navistar offered a sleeper compartment with a roof extending above the front seats.

Third generation (9800i; 1999-2015)

Following the discontinuation of the Newport Series in the North American market, Navistar continued cabover production by sending the tooling for the model line to Brazil. Outside of Brazil, the 9800i was exported throughout South America, with right-hand drive production exported to Australia and South Africa. In 2015, production of the 9800i was halted.

In August 2017,[1] the truck was still sold in South Africa.
