Kenworth features new natural gas mixers trucks at World of Concrete

January 30th, 2013 | Posted in News


Kenworth’s newest engine offering and latest vocational product line for ready mix operators and construction businesses will be on display at the World of Concrete Show February 4-8 at the Las Vegas Convention Center.

Kenworth’s World of Concrete booth (C5602) features a lineup of five Kenworth mixer trucks, including two natural gas vehicles. The new 2013 PACCAR MX-13 engine makes its trade show debut at this year’s show. The new 12.9-liter engine offers a range of 380 to 500-hp and 1,450 to 1,850 lb-ft of torque. The high end horsepower and torque ratings are an increase over those previously offered for the 2010 PACCAR MX engine, which the PACCAR MX-13 replaces in 2013.

The new engine is available for the Kenworth T800 and W900 typically selected by vocational customers, in addition to Kenworth’s T660, T680 and T700 aerodynamic trucks for over-the-road applications. At the show, the PACCAR MX-13 will be displayed in a Kenworth W900S mixer rated at 380 hp and 1,450 lb-ft of torque and equipped with an Allison 4500RDS 6-speed transmission and Con-Tech mixer body.

Two Kenworth mixers – a T440 and W900S – with natural gas engines will be in the booth. Both vehicles are specified with the Cummins Westport 8.9-liter ISL G engine, Allison 4500RDS 6-speed automatic transmission and McNeilus mixer body. Rated at 320 hp and 1,000 lb-ft of torque, the ISL G uses a maintenance-free, three-way catalyst and is 2010 and 2013 EPA and CARB compliant without the use of selective catalytic reduction (SCR) technology or a diesel particulate filter (DPF).

The remaining two Kenworth mixers are a T800 short hood and W900S. The T800 short hood has a PACCAR MX engine, Allison 4500RDS 6-speed transmission and Beck Industrial mixer body. The W900S is a California lightweight spec mixer with a Cummins ISL9 engine rated at 380-hp and 1300 lb-ft of torque, an Eaton RTO14909ALL 11-speed transmission and McNeilus mixer body.
