After Volvo introduced its first ‘downspeeding’ concept with the XE13 powertrain package for the D13 engine, in September 2011, the company is launching two new XE efficiency packages for the 16-liter D16 engine which develops a maximum power of 500 hp with a peak torque of 780 Nm.

The first package was designed for the heavy long combination vehicle segment with GCWs (gross combination weights) of up to 143.000 pounds, while the second package is aimed at tractor semitrailer combinations with GCWs of up to 80.000 pounds.

Ed Saxman, Volvo Trucks drivetrain product manager said, “XE16 directly addresses the needs of two important market segments that historically have had very few fuel-efficient powertrain options. The beauty of Volvo’s XE powertrain is that it delivers the full power and low-end torque needed for higher weight applications while saving fuel by running at a lower rpm.”

For an improved efficiency, the XE16 packages ‘downspeed’ the engine at cruising speeds by 200 rpm or more than traditional specs. The XE16 provides the full torque while running as low as 1,000 rpm to improve low-rpm drivability.

The packages are combined with company’s I-Shift automated gearbox, specialised axle ratios, specific tyre sizes and proprietary software that facilitates communication between Volvo’s integrated powertrain components.
