As we reported last month, Detroit Diesel and Freightliner are ready for ’07 (CCJ, April ’06, p 12).

And at the Mid-America Trucking Show in March, Chris Patterson, president and chief executive officer of Freightliner, announced that Detroit Diesel and Mercedes-Benz duty engines will add between $7,000 and $10,000 to the price of 2007 Freightliner heavy-duty trucks, while Mercedes-Benz engines in Freightliner medium-duty trucks will add $4,500 to $6,000 to the purchase price.

Cummins, meanwhile, announced that its 2007 heavy-duty engines will be available in several new ratings, including a 600-hp rating for its ISX model. Despite emissions changes, Cummins says a full lineup of ratings will be available for the ’07 ISX and ISM, including three new ratings for the 2007 ISX: the ISX 425 SmartTorque, the ISX 485 SmartTorque and the ISX 600.

The ISX 425 SmartTorque, designed for truckload fleets, provides 1550 lb-ft of torque in lower gears, but in higher gears, it produces 1750 lb-ft. The ISX 485 rating operates the same way and is designed for the premium truckload market, while the ISX 600 is designed for heavy-haul applications and owner-operators and features 1850 lb-ft of torque. ISX and ISM engines for 2007 will be available in limited production in the fourth quarter of this year.

Caterpillar’s line of medium- and heavy-duty engines – the C7, C9, C13 and C15 – will continue to rely on Cat’s ACERT technology to meet emissions standards, and will be available beginning in the fourth quarter of 2006.

Cat’s enhanced ’07 ACERT will recirculate a small amount of exhaust gas that has passed through a particulate filter, cooling and mixing it with fresh air before reintroducing it into the intake – a process Cat calls Clean Gas Induction, or CGI.

At the top end, Cat’s heavy-duty 15.2-liter C15 engine features horsepower ratings from 435 to 625, with torque ratings from 1550 to 1850 lb-ft. The 625-hp C15 has a torque rating of 1850-2150 lb-ft.

The 12.5-liter C13 will be available in on-highway, vocational and heavy-duty linehaul configurations. Horsepower ratings range from 305 to 370 and torque from 1150 to 1750 lb-ft, while the 9.3-liter C9 will have horsepower ratings of 285 to 350, and torque ratings from 890 to 1350 lb-ft.

And last, the mid-range 7.2-liter C7 engine will produce 190-300 hp and 520-860 lb-ft of torque at 1440 rpm.

Over at Mack, The MP (Mack Power) 7 will displace 11 liters with six ratings from 325 to 405 hp, and torque ratings from 1260 to 1560 lb-ft. New homes for the MP7 will include the Granite vocational truck and the new Pinnacle. Mack also announced plans to launch the 13-liter MP8 in ’07, with ratings from 415 to 485 hp and torque from 1540 to 1700 lb-ft; and the 16-liter MP10 engine at a future date.

Not surprisingly, Volvo will have a similar lineup – since Volvo Powertrain supplies engines for both Mack and Volvo. The 11-liter D11 will be available in the Volvo VNM and VNL, with horsepower ratings from 325 to 405, and torque ratings from 1250 to 1450 lb-ft. Primary applications will be P&D, LTL and regional distribution.

The 13-liter D13, which replaces the D12, will be available in Volvo VNM and VNL tractors, as well as the VHD vocational truck and tractor. Ratings will be 335-485 hp, with torque levels of 1350-1650 lb-ft. Applications for the D13 include LTL, truckload, linehaul freight and vocational duties.

And the 16-liter D16 again will be available in the Volvo VNL and VT, with horsepower ratings from 450 to 600 and torque from 1650 to 2050 lb-ft. It’s intended for heavy hauling, owner-operators and small, premium fleets.

That’s the latest on what will be available for ’07 models. We’ll bring you reaction from early users in our next installment of “Clearing the Air,” coming up in November.
