AAA answers questions about engine stop-start technologies
The idea of stopping an idling engine automatically, whether in traffic, parked and waiting, or otherwise not moving the vehicle, is not new. The technology has been around since the 1980s and has become very popular in Europe and parts of Asia. Until recently, however, it was not something offered on vehicle models sold in the U.S.
Truckers know this technology as "anti-idle shutoff" and have become accustomed to it as anti-idling laws and fuel savings become important to their industry. In passenger cars, however, the idea has only recently come to American shores. Lux Research recently predicted that more than eight million cars with stop-start tech will be on the roads in this country by 2017, so anti-idling systems are expected to become much more commonplace here.
With that, AAA Insurance has issued a few answers to commonly asked questions about this new technology. Before we get into those, however, let's look at what stop-start is and why it's being included in cars today.
What Is Stop-Start?
Stop-start is a generic name given to a host of branded technologies that all do the same basic thing: turn the vehicle's engine off when it is idling for too long. The engine is automatically started when the situation changes. For example, a vehicle stops at a light and after a few seconds, its engine shuts off. When the driver presses the accelerator again after the light changes to green, the engine automatically starts again and the vehicle moves.
