as the successor to the 357 and 378, the 365 and 367 were introduced, serving as heavy-duty Class 8 trucks; along with vocationally-oriented configurations, the model line is also offered as a tractor. In 2007, the company withdrew the 210/220 medium-duty COEs, as second-party equipment manufacturers found difficulties adapting to its European-based design. After a 20-year production run, the Model 379 was retired, replaced by the Model 389. Sharing its cab with the 2005-2007 379, the 389 was designed with a longer hood (the longest-ever Peterbilt conventional), upgraded headlamps, and aerodynamic improvements. In 2009, Peterbilt ended production at the Madison, Tennessee facility, consolidating operations between Denton and Sainte-Thérèse. The medium-duty line saw a slight revision; along with adoption of (Cummins-built) PACCAR engines and a redesigned interior, the 335 and 340 were dropped, replaced by the 337 and 348. 2010s In 2010, the Model 587 was introduced as a wide-cab aerodynamic tractor, serving as the successor of the 387. Sharing its cab structure with the Kenworth T700, the 587 (the first Peterbilt with a "5" model designation) adopted a sharper-edged hood from its predecessor, achieving improvements in aerodynamics, forward visibility, and lighting. The Model 382 was introduced as a regional-haul daycab tractor, serving as a shorter/lighter version of the 386/384. In 2011, the Model 210 and 220 COEs made their return. Assembled in the PACCAR facility in Mexicali, Mexico (alongside the Model 320), the 210/220 now used the chassis of the 325 and 330 (only sourcing the cab assembly with the DAF LF), allowing for increased mechanical commonality and simpler adaption of equipment. As before, the model was shared with Kenworth as the K270/K370. The company introduced a design variant of the Class 8 1100-series cab, introducing an "Extended Ultra Daycab" for non-sleeper; the option included a raised roof and extended rear cab wall. In 2012, the Model 579 was introduced as the Peterbilt wide-cab aerodynamic tractor. Replacing the 587 (which remained in production), the 579 served as the flagship model line alongside the "traditional" 389. Debuting an all-new cab design (no longer shared with Kenworth), the 579 improved outward visibility (by deleting vent windows), further improved aerodynamics (with redesigned body skirting and optimized under-body design), and improved serviceability. In 2013, the Model 567 was introduced as a Class 8 heavy-duty truck. Sharing its size and functionality with the 367, the 567 adopted the newer cab design of the 579 (fitting
