CATERPILLAR’S ’07 LINEUP

Cat’s 2007 C15 engine

There are four models in the 2007 Caterpillar on-highway engine line — the C7, C9, C13 and C15 — all equipped with ACERT technology. They’ll be available to order beginning in fourth quarter 2006, and Cat says there will be no loss — and in the case of mid-range, a gain — in fuel economy.

The 7.2-liter C7 truck engine provides ratings of 190 to 300 hp at 2200 rpm, with 520-860 lb ft of torque at 1440 rpm. The C9 now provides heavy-duty power with increased displacement – to 9.3 liters. Including a Cat integral brake, its ratings go from 285 to 350 hp at 2100 rpm in truck trim, with torque from 890 to 1350 lb ft. A new common rail fuel system optimizes performance and is claimed to increase fuel economy by up to 4% over previous models.

The new C13 is available in on-highway vocational and heavy-duty linehaul configurations. At 12.5 liters it delivers 1150-1750 lb ft of torque at 1200 rpm, with vocational truck ratings of 305-370 hp and linehaul truck ratings of 380-470 hp. Cat says the new vocational C13 will provide higher torque, better response, improved driveability, automatic transmission compatibility, and higher
compression braking.

The 15.2-liter C15 can still be had with 625 hp and 1850/2150 lb ft of torque at 1200 rpm. Other ratings start with 435 hp at 2100 rpm, with torque ratings of
1550-1850 lb ft.
