Major truck and engine manufacturers have brokered a truce with California’s plan for phasing out sales of Classes 4-8 diesel-powered trucks in a landmark deal with state regulators.

The Truck and Engine Manufacturers Association filed a federal lawsuit May 27 alleging that California environmental regulators have failed to give manufacturers enough lead time to meet the state’s new, more rigid emission standards.

NASHVILLE, Tenn. — Engine makers, two of whom also build heavy-duty trucks, emphasized the powerful role of telematics in delivering customer support as they announced service-related features.

Before leaving town for Thanksgiving, House Speaker Paul Ryan reaffirmed his stance that federal regulators relax their rulemaking until the start of President-elect Donald Trump’s administration.

Fleet-tracking companies Teletrac Inc. and Navman Wireless announced a new telematics platform that combines their two product lines into one offering for customers. 

Telematics provider Geotab introduced a telematics device, Go Rugged, intended for harsh outdoor environments and developed for fleets with industrial heavy-duty and service vehicles.

Volvo Group’s two North American truck making units, Mack and Volvo, said they are offering the option to link their remote diagnostic systems with communications services from Omnitracs with the goal of providing fleet managers with more information on safety and operations.

Magtec Products Inc. announced that it has formed a new venture to integrate its anti-theft and driver-management software with major global telematics providers.
