Thought this might be of interest to some of you following CAT's decision to stop supplying engines to the on-highway market.

First Look At Navistar’s MaxxForce 15
March 23, 2009
Navistar gave the first look at its new MaxxForce 15 diesel engine at the Mid-America Trucking Show. Contrary to some reports, the engine is not simply a rebadged Caterpillar C15, though it does borrow significant componentry from what had been Cat’s flagship truck engine until the Peoria, Ill., company announced its withdrawal from the truck engine business in mid-2008.
The new engine, which is expected to be available sometime in late 2010 or early 2011, will be available in ratings from 435 to 550 hp with maximum torque ratings as high as 1850 lb. ft. With a 15.2 L displacement on a bore and stroke of 137 x 171 mm, it will adhere to Navistar’s no-SCR strategy and instead rely on cooled EGR to meet the stringent 2010 EPA emissions standards.
Caterpillar’s components will provide much of the structural and mechanical foundations. Specifically, the MaxxForce 15 will incorporate the cylinder block, crankshaft, camshafts, connecting rods and cylinder head from the C15. Navistar will add a second-generation common rail fuel system that can deliver injection pressures as high as 31,800 psi, twin series turbochargers and electronic controls, all of which are already used on its MaxxForce 13 diesel, the company said.
Navistar demonstrated a running engine in a truck at Mid-America and said other units were running in test. The engines will be assembled in Huntsville, Ala., where the company builds several of its MaxxForce diesel models.
