Future trends in engine displacement

What is the future of engine displacement?

Overall Power Needs

The debate on engine displacement will continue as trucks and engines continue to evolve to meet changes in regulations. Greenhouse gas emissions standards are pushing both truck and engine manufacturers to develop products that use less fuel.

Vehicle improvements are likely to reduce overall power engines need to provide, but engine technology selection will continue to influence optimal displacement.
