Finally!I've been saying for years that all non-hybrid, non-electric vehicles should at least have stop-start anti-idling technology. We've had the technology to do it for a long time, fuel savings would more than pay for the upgrade, and air quality improvements in cities - where there is a lot of vehicles pointlessly idling at red lights and in traffic - would be significant.
And now, a Ford representative is saying that they are "going to be aggressive rolling [stop-start] out". About time! I hope other automakers will follow suit.
When a vehicle equipped with a start–stop system reaches a standstill, the engine automatically stops running and resumes again when a sensor detects the driver's foot is lifting off the brake pedal.
Nair said it would not be difficult to install the system on Ford's current car and light-truck models.
"It's not a major tear-up to do it," [Raj Nair, Ford's global product development chief] said in an interview here at the Los Angeles Auto Show. (source)
Right now, the Ford Fusion EcoBoost 1.6-liter (pictured above) is the only non-hybrid model available with stop-start. It's a $295 option, but the company estimates that it could save customers about $1,100 in fuel costs over 5 years (obviously, that depends on how much you drive, how much of it is in the city, etc).
Using Ford's number, that's $220 of savings per year. So the technology would pay for itself in a bit more than 1 year and then save you money for as long as the vehicle is on the road. Not even considering the environmental benefits, the financially sane thing to do is to get it.
In fact, there wouldn't even be any financial pain in the first year. Because most people pay for their vehicles over many years, the $295 cost would be spread out. Over 5 years, that would be $59/year, which is less than the $220 fuel savings. So your monthly expenses would actually be lower with the stop-start option!
