PEORIA, Ill. – Caterpillar officials are touting 2005 as a banner year in the history of the company, with more than 1.5 million Cat engines on the road today and more than 1.1 million on-highway engines shipped since 1995.

Officials are attributing much of their success in recent years to the response the company has experienced since the introduction of its ACERT Technology. To date there are more than 43,000 companies using over 322,000 vehicles equipped with the technology.

“Developing ACERT Technology involved a huge investment in research,” says Jim McReynolds, general manager, Caterpillar Power Systems North America. “This technology was designed to meet stringent emissions standards without sacrificing performance or fuel economy, and to provide customers greater value now and in the future.”

Caterpillar will unveil its ACERT Technology for 2007 at the Mid-America Trucking Show in Louisville, Ky.

In addition to the company’s success with ACERT, the CAT C-15 was also awarded J.D. Power and Associates’ “Highest in Customer Satisfaction with Vocational Heavy Duty Diesel Truck Engines” in 2005. A Caterpillar engine has ranked highest in the vocational segment all five times the award has been given.
