In the midst of an on-going revitalization of the iconic Western Star brand, the company has introduced a new auto hauler package on its 4900 model. It sports a low 101.5-in. ground-to-top-of-cab height without needing third-party modifications to the cab roof.

The only power option is the Cummins ISX15 engine with ratings from 400 to 600 hp and up to 2050 lb ft of torque. A horizontal aftertreatment system is standard.

It’s now available to order with a BBC of either 123 or 132 in. in daycab or sleeper configurations. The company says there are no compromises to the full-height headroom or sleeper access. Available sleeper options include 40-, 54- and 68-in. models.

On the daycab you get a 190-gal fuel tank matched with a 13-gal DEF tank. Uniquely, this model has its batteries situated in the cab. Tanks max out with the 68-in. sleeper model, offering 250-gal fuel capacity and a 23-gal DEF tank.

The in-cab three-battery setup — arranged under a specially designed seat — is actually offered on any Western Star daycab and up to 40-in. sleeper models equipped with DD13 and ISX engines. It frees up scarce chassis space, with battery cables routed through the floor and under the deck, while reducing the vibration stress that’s common with frame-rail mounting.
Among other features, you’ll have a 40-gal hydraulic tank on the auto hauler.
