Study: Adaptive Cruise Control Can Cut Fuel Usage by 7%

The use of adaptive cruise control (ACC) can reduce fuel consumption by as much as 7%, according to a study by Volvo Car Corp. and researchers from the U.S. National Renewable Energy Laboratory.

The analysis tracked the fuel efficiency of Volvo cars operating with ACC and those without the technology on 18,500 trips near the carmaker’s headquarters in Gothenburg, Sweden. The results were published in the Institute of Electrical and Electronics EngineersIntelligent Transportation Systems magazine.

The study notes that ACC, which gradually slows speed to that of the preceding vehicle, is a building block for autonomous driving. Future advances, such as vehicle-to-vehicle communications and platooning, likely will further smooth traffic flow and boost fuel economy, the authors say.
