I was surprised by what I found yesterday.
Well you got me thinking, so yesterday I asked my wife to trade cars with me. She drives a 2018 GM product with start/stop. I used the timer on my phone to keep track of how much time it was engaged. On my 6.2 mile drive to work in the morning that takes about 20 minutes the start/stop was engaged for 4:52. Assuming the drive home is similar or more congested, that’s 10 minutes right there. Lunch break to hit the Burger King drive through, evening trips to drop off and pick up my kid from baseball practice, I can easily see 20-30 minutes a day of wasted idling time. I had no idea it would be that much.
Correct my math if I’m wrong. If I spend 20 minutes a day, 5 days a week idling, .3 gallons per hour, that’s roughly half a gallon a week. 50 work weeks in a year, 25 gallons of gas per year.
Remember, start/stop technology is only about using less gasoline at the pump and reducing automotive tailpipe emissions. Talking about gas prices, manufacturing emissions, and repair costs are clouding the original goal.
