Over the past few years there have been several trends in vehicle components, laws and standards. These trends are going to shape the future of fire apparatus, and their effects will be both good and bad.

On the positive side, these trends will produce apparatus that are safer, more effective and less harmful to the environment. On the negative side, some of these same trends also will result in apparatus that are more expensive, more difficult to maintain and less varied in options. Here’s a brief look at what fire apparatus buyers might expect in the next few years.

Engines. Buyers don't have to look any further than next year to see one significant trend that will have a major impact on apparatus — and on all diesel-powered vehicles. The 2007 diesel engine emission laws are expected to require larger cooling systems, more exhaust components and special fuel and oil. All of these changes are expected to add cost and restrict the use of certain options. Maintenance procedures will include periodic cleaning of particulate filters with specialized, and expensive, equipment. In 2010, an even tougher emissions law takes effect and will require further changes to diesel engines.
