Volvo’s 2007 engine family will include the new 10.8-liter D11, the 12.8-liter D13 that’s a stroked D12, and the updated 16.1-liter D16, and the company says they’ll deliver fuel economy equivalent to current engines. Cummins ISX engines will also be available in Volvo VT and VNL trucks next year through at least 2010.

While there have many detail changes compared to the current D12 and D16 motors, all three models will continue to use cooled
exhaust gas recirculation (EGR) technology with the addition of diesel particulate filters (DPF) made by Fleetguard, a Cummins subsidiary.

A key difference will be the price – at a press conference during the annual meeting of the Technology & Maintenance Council in
Tampa, Fla., Volvo said that the price increase for its trucks next year will be $7500 to cover the massive amount of work that’s been
done to meet the ’07 requirements, including new technology for the engines, exhaust aftertreatment systems, cooling system
enhancements, and changes to electronic engine controls.

The D11 will be available in the Volvo VNM (medium hood length) and Volvo VNL (long hood) models. Rated from 325 to 405 hp, with torque from 1250 to 1450 lb ft. At just 2175 lb, it will suit weight-sensitive applications and local/regional haulers.

The D13, a re-worked D12, is for VNM and VNL tractors, as well as the VHD vocational machine, with 335 to 485 hp and torque levels from 1350 to 1650 lb ft. It weighs 2250 lb.

The big D16, first introduced here in 2005, has been updated to next year’s emissions standards. The D16 will again be available in the Volvo VNL and Volvo VT but its top 625-hp rating has been dropped. For 2007, it will be available with 450 to 600 hp, and torque from 1650 to 2050 lb ft. The D16 weighs 3070 pounds.

Oil-drain intervals for the new engines are, depending on duty cycle: up to 30,000 miles for the D11; up to 45,000 miles for the D13;
and, up to 50,000 miles for the D16.

On the serviceability front, the ’07 particulate filters will need to be removed and cleaned at 150,000 miles or better, a job that will take
about 90 minutes, Volvo says. The new EPA demand for crankcase ventilation is met by a centrifuge ‘filter’ that will need no
maintenance.
