This cat's out of the bag

| January 03, 2006

I asked about costs. “That varies from engine to engine, from OEM to OEM,” says Keene. “There’s no relationship between our cost increase and the end user’s.”

Our return to the Cat plant was like the entire 100-mile, two-hour test drive: remarkable only in that it was unremarkable. In other words, Cat’s ’07 on-highway ACERT engines, even spec’d with flatlander gears and a nine-speed transmission and pulling heavy loads up long inclines, will perform as well as earlier model Cat engines. If spec’d to its maximum 625 horsepower and 2,050 pounds-feet of torque and matched with the right transmission, rear end and tires, Cat’s ’07 C-15 will likely provide enough pulling power to handle even the heaviest applications over the long term.

The biggest difference is that Cat’s ’07 ACERT engines exceed EPA emissions requirements, so long as low-sulfur fuel is available. There’s no loss of power, weakness or strain. Cat’s modified fuel/air injection and exhaust systems will not decrease their ’07 engines’ performance.
