BETTER PERFORMANCE AND EFFICIENCY TO KENWORTH’S CLASS 8 TRUCK LINEUP
Kenworth Heavy Duty trucks remain popular in the class 8 market as they launch their new T680 line. The new models have all-new engines coupled with the PACCAR TX-12 automatic manual transmission, introduced last month, and DX-40 axles designed to improve fuel economy, smoother driving, increased power, longer maintenance intervals, and easier servicing.
These heavy-duty trucks feature two new MX-series engines with multi-pulse fuel injection, friction-reducing pistons, and smaller yet more efficient turbos. The PACCAR MX-13 generates up to 2.4% better fuel economy and is available with up to 510 HP and 1,850 lb-ft. of torque. The MX-11 provides up to 3.4% better fuel economy and is available with up to 445 HP and 1,700 lb-ft. torque. The updated exhaust after-treatment system lessens particulate and NOx emissions.
According to Kenworth engineers, T680 can go up to 75,000 miles between oil and fuel filter changes. A 12-volt fuel heater comes standard on all engines, making startup easier in severe weather. The engine harness is fully encapsulated to limit electrical corrosion problems and uses fewer connections to the vehicle. The longest guarantee in the industry is for these heavy-duty trucks’ major components warranty, which is five years, or 500,000 miles. The PACCAR TX-12 and the new MX engines are devised to work together with Kenworth’s predictive cruise control that utilizes GPS to check upcoming grades, tweaking the throttle automatically to make the most out of the fuel economy through a process of data gathering processing and precision hardware.
