Kenworth is please to announce the launch of its new Vehicle Electronic Control Unit [VECU] for North America 2.1 meter products.  The VECU enhances the core electrical architecture of Kenworth’s 2.1 meter platform, providing expanded vehicle functionality to further meet the needs of customers in areas such as MX PTO functionality, driver-assistance programs and advanced driver controls.  The new VECU electrical architecture is an evolution on the technology used in the current Cab Electrical Control Unit.  The controller will be expanded in both software capacity and signal input/output.  All North American 2.1 meter base models will come standard with VECU starting in October.


Kenworth is pleased to announce the availability of Dana 172 series axles.  These axles replace the Dana 170 series axles, and, according to Dana, provide increased durability, reliability, and efficiency while reducing weight.  The 172 series axles feature design improvements on the rear axle housing/carrier interface, internal gearing improvements and increased torques capacity for certain applications.  The Dana 172 rear axle uses 10 pints less lube than the Dana 170.

WABCO has released a new 500k baud rate camera for its OnLane Alert System in T680 and T880 models.  The camera replaces the 250k baud rate camera.  OnLane Alert is a camera-based warning system that helps vehicles avoid unintentional land drifting.  The system utilizes a camera mounted near the top center of the windshield to monitor and calculate the vehicle’s position within the lane.  When OnLane Alert detects the vehicle crossing land markings without the turn signal being activated, the system sounds an audible warning.  This alerts the driver to take a corrective action to prevent potential collisions or run-off-road accidents,

Beginning August 1, 2019 Phase 2 of the Federal Motor Vehicle Safety Standard 136 , Electronic Stability Control, becomes effective for all tractors with a Gross Vehicle Rating greater than 26,000 pounds.  This phase implements for both U. S, and Canadian chassis.  Phase 1 of the standard took effect August 1, 2017 for 6×4 tractors.  Phase 2 will include all other tractors, including 4×2, 6×2, tridems, and lift axles.  Any tractor featuring a single axle with an engineering assigned GVWR of 29,000 pounds or more is excluded.  Full trucks and gliders are also excluded.  To ensure chassis will be manufactured in time to meet the August 1, 2019 requirement, Kenworth will implement Phase 2 of the standard for trucks scheduled July 1st, 2019 and beyond.

Dana Spicer’s S140 single-reduction single-drive axle is now standard equipment on medium duty models T270 and T370.  The T270 features the S17-140 rated at 16,000 pounds while the T370 is spec’ed with the S21-140 rated at 21,000 pounds.

Kenworth announces the expanded availability of the WABCO OnGuardActive Collision Mitigation System and WABCO SmartTrac Electronic Stability Control to K270 and K370 models.  Automatic Traction Control is now part of the standard WABCO Electronic Braking System and will be included with all K270s and K370s moving forward.  OnGuard Active and Electronic Stability Control both require Automatic Traction Control.  The OnGuardActive Collision Mitigation system supports drivers with collision warning and autonomous brake application to help avoid or mitigate collisions.  OnGuardActive applies braking on moving, stopped and stationary vehicles and also provides maximum speed reduction up to -3.5m/s2 to minimize impending collisions.


Kenworth Truck Company has made its second natural gas announcement of August announcing the availability of the Cummins ISX12N near zero NOx emissions natural gas engine for the T680, T880 and T880S models.  The ISX12N is certified by the Environmental Protection Agency and the California Air Resources Board.  The engine meets CARBs optional low NOx standard of 0.02 g/bhp-hr which represents a 90 percent reduction from engines operating at the current EPA NOx limit of 0.2 g/bhp-hr, the company says. ” The Cummins Westport ISX12N provides an excellent, very low-emissions solution for fleets and truck operators that order the Kenworth T680, T880, and T880S for line haul, regional haul, vocational and refuse applications,” says Kurt Swihart, Kenworth marketing director.  In addition to offering ultra-low emissions, Kenworth says the ISX12N engine features a closed crankcase ventilation system, unique maintenance free three-way catalyst, on-board diagnostic capability and engine control module with excellent durability.  The Kenworth T680, T880 and T880s offer the 12-liter ISX12N ratings with 400 hp and 1,450 lb-ft of torque.  The engine can operate on compressed natural gas and liquified natural gas as well as renewable natural gas, which offers additional reductions in GHG emissions.  RNG is produced from the decomposition of organic waste from such sources as dairy farms, landfills, and urban waste treatment plants, the company says.
