the Mid-Ranger became the K300, as PACCAR shifted production to Sainte-Thérèse, Quebec. In 1993, Kenworth opened its facility in Renton, Washington, as its third United States assembly plant. In 1994, the T300 was introduced as the first Kenworth medium-duty conventional truck, adapting the T600 to a lower-GVWR Class 7 weight rating. The Aerocab sleeper was introduced, integrating the Aerodyne II sleeper cab and the drivers' cab as a single unit. In 1996, Kenworth introduced the T2000 as its next-generation aerodynamic conventional. While not directly replacing the T600 and W900, the T2000 was a completely new design (the first from Kenworth since 1961). The first "wide-body" Kenworth conventional, the model shared its cab with Peterbilt, distinguished by its bumper-mounted headlamps. The T2000 was discontinued in 2010. In 1998, parent company PACCAR purchased British truck manufacturer Leyland Trucks, two years after Dutch manufacturer DAF Trucks (the two had been merged as Leyland DAF from 1987 to 1993). Within PACCAR, DAF would develop COE trucks for Kenworth and Peterbilt. 2000s-present: 21st-century trucks In 2000, Kenworth redesigned its medium-duty COE range, with the K300 replacing the MAN-sourced design with a DAF 45 (Leyland Roadrunner) cab. Following declining demand for Class 8 cabovers, the K100E was quietly phased out after 2002 production in North America; Kenworth Australia continuing production of the model line. In 2006, the company released the K500, the largest COE ever produced by the company. Developed primarily for off-highway applications, the K500 combined the chassis of the heavy-duty C500 and the COE cab of the DAF XF; all examples produced from 2006 to 2020 were sold for export. In 2008, Kenworth underwent a modernization of its model line. The T600 underwent a substantial revision to its aerodynamics, becoming the T660. The medium-duty T300 was replaced by the Class 5-7 T170/T270/T370 model family. The low-cab COE made its return, based on the DAF LF. Initially marketed as the K260/K360, the model line was renamed the K270/K370 for 2013. The T660 would be discontinued in 2017. For 2011 production, the T700 replaced the T2000, adopting a larger grille and fender-mounted headlamps. For 2013 production, the T680 was introduced as the third-generation aerodynamic Kenworth conventional, serving as a single replacement for the narrow-body T660 and the wide-body T700. The T700 was discontinued in 2014 while the T660 was discontinued in 2017 (32 years after the introduction of the T600). Sharing the same cab as the
