Eaton Corp. announces Volvo Trucks will now offer the SmartAdvantage Powertrain in all VNL Series models in order to maximize fuel efficiency in linehaul and regional haul applications. In addition to lighter weight and increasing the driver pool with smooth, automated shifting, this powertrain is designed to enhance the time spent in a diesel engine’s most efficient RPM zone helping to reduce fuel consumption, Eaton says.
“Partnering with North American truck manufacturers to deliver integrated powertrain solutions is a key part of Eaton’s strategy,” says Tim Sinden, president – North American Truck Operations at Eaton. “Eaton has a long history of providing our fleet customers with enhanced, optimized powertrain choices, and we believe this new offering for Volvo’s VNL Series will be well received by the marketplace and professional drivers.”
The SmartAdvantage Powertrain for Volvo combines a Fuller Advantage Series Automated Transmission with the Cummins ISX15 engine with SmartTorque2. This package has been embraced by customers since its launch last year while receiving industry accolades as a top new product. Delivering fuel economy improvements between 3 and 6 percent, Eaton says more than 80 customers have taken delivery of trucks with the SmartAdvantage Powertrain or have orders pending, with many confirming that their expectations in fuel economy improvements have been met or exceeded under real-world operating conditions.
“Volvo Trucks is continuously looking for fuel efficient solutions for our customers,” says Wade Long, director, product marketing, Volvo Trucks. “The SmartAdvantage is one opportunity in the Volvo product offering to allow customers to ‘downspeed’. Downspeeding provides additional fuel savings for every 100 RPM we can reduce engine speed.”
Eaton says a new Precision Lubrication system represents one of the most important upgrades in the Fuller Advantage Series. The system reduces the oil churn energy losses found in traditional transmissions by nearly 33 percent. With less heat being generated, the Fuller Advantage Series transmissions do not require a cooler and corresponding lines and fittings. The result is less preventative maintenance is required while engine fans cycle less, further reducing horsepower demand, the company says.
In addition, small-step technology enables downspeeding in overdrive and efficiency in direct drive. Optimized shifting is based on grade, vehicle weight, engine torque and throttle position.
Significant weight savings – up to 82 lbs. with no sacrifice to strength – has also been achieved with the new Fuller Advantage Series transmissions. A thin-wall cast-iron main case design is complemented by the strategic use of aluminum for the shift bar housing, auxiliary section cover and range cylinder.
Eaton says all Fuller Advantage Series transmissions have a standard warranty of 5-years/750,000 miles. The Advantage Series clutch is warranted for 3 years/350,000 miles (563,270 km). Extended protection plans are also available.
