Navistar offering Allison fuel-efficiency package on medium-duty and vocational trucks

Navistar, Inc. is offering the Allison Transmission FuelSense fuel-efficiency package on its medium-duty and vocational International truck models. FuelSense, available in Allison’s 1000, 2000, 3000 and 4000 series transmissions, automatically adapts shift schedules and torque, maximizing transmission efficiency based on load, grade and duty cycle, without sacrificing performance.

FuelSense features are incorporated in part or completely in three levels: FuelSense Basic, FuelSense Plus and FuelSense Max. All features are available in the 3000 and heavy-duty 4000 series and will be available in the 1000 and 2000 series transmissions later this year.

Cummins 6.7L Turbo Diesel first medium-duty engine certified to meet LEV III standards

Cummins Inc. has received certification for its 6.7L Turbo Diesel from the California Air Resources Board (CARB), meeting the Low-Emission Vehicle III (LEV III) standards. This new standard applies to all vehicles under 14,000 lb GVWR. The Cummins 6.7L Turbo Diesel powers the Ram Heavy-Duty lineup, and is the first medium-duty diesel engine in the 8,501-14,000 lb GVWR segment to be certified to the new 2015 LEV III standards.

Under LEV III, NOx and non-methane organic gas (NMOG) standards are combined into a single NOx+NMOG standard, along with extension of emissions-useful life to 150,000 miles for emissions control systems. LEV III standards also introduce more stringent NOx+NMOG fleet average requirements, which phase in from MY 2015-2022 for all medium-duty vehicles.

These new standards were adopted by the Air Resources Board (ARB) in January 2012.

Cummins began providing diesel engines to Chrysler in 1988, and has shipped more than 2 million engines in the last 25 years.

Volvo Trucks boosts fuel savings with MY 2016 enhancements

Volvo Trucks’ model year 2016 VN series heavy-duty highway tractors will deliver greater fuel savings than previous generation models through an assortment of aerodynamic and powertrain enhancements. Further sculpting of airflow around the exterior and underneath the hood improves fuel efficiency by up to 3.5%. Volvo’s new XE-Adaptive Gearing and Torque Management options can provide fuel efficiency improvements of more than 2.5%.

Enhancements to the bumper, chassis and roof fairings of model year 2016 VN series highway tractors reduce air turbulence around the vehicle exterior and improve airflow under the truck, around tires and the trailer gap. Reducing turbulence and disruptions in airflow from the tractor to the trailer helps improve fuel efficiency.

Building on its XE (eXceptional Efficiency) powertrain packages, Volvo will offer an XE-Adaptive Gearing package to further boost fuel efficiency for operations that go out loaded and return empty or lightly loaded, such as bulk haulers, liquid tankers and flatbed carriers. XE-Adaptive Gearing provides the same benefits for dry van trailers operating under the same conditions.

The system is both a direct and overdrive driveline depending on rear axle load, which the system senses in real-time. When loaded, the transmission locks out the 12th gear and provides the performance and fuel efficiency benefits of direct drive. During unloaded or lightly loaded trips, the driveline operates in overdrive, providing enhanced fuel efficiency and even greater driver comfort.

Customers can select road speed limits for loaded and unloaded portions of the trip, customizing their vehicle speeds to fit operating needs. XE-Adaptive Gearing engine ratings will initially be available for Volvo’s D11 and D13 engines paired with an I-Shift automated manual transmission.

Volvo Trucks is also offering three new torque control features designed to increase fuel efficiency, tire life and decrease driveline stress. The expanded offerings utilize Volvo’s numerous multi-torque engine profiles to provide optimized torque management in multiple operating environments.

2015 Chevrolet City Express achieves 24 mpg city

Chevrolet announced today the fuel economy for the 2015 City Express cargo van. The company’s first entry into the small van segment will offer an EPA-estimated 24 mpg city and 26 mpg highway, resulting in 25 mpg combined.

The vehicle’s 2.0L dual-overhead cam inline-four-cylinder engine matched to a continuously variable transmission allows the vehicle to achieve greater efficiency on the road, especially when driving in the city.

“The 2015 Chevrolet City Express is designed for our customers who are looking for a small, easy-to-maneuver, fuel-efficient, cargo-carrying vehicle,” said Ed Peper, U.S. vice president, GM Fleet & Commercial. “The fuel economy of the City Express will help stretch their dollar at the pump and give them the flexibility to invest the savings back into their business.”

All types of businesses – from florists to food delivery – will benefit from Chevrolet’s service and support, including two-year/24,000-mile (whichever comes first) standard maintenance that helps businesses keep their vehicles in shape and on the job. Read more »
