Is it just me or is having your vehicle shut off at every stop about the dumbest thing they will ever be able to come up with to save fuel? It's on just about every new gas vehicle on the market now.
Why is it dumb? At idle fuel is being burned with no movement. It's wasted fuel. Why not save it?Is it just me or is having your vehicle shut off at every stop about the dumbest thing they will ever be able to come up with to save fuel? It's on just about every new gas vehicle on the market now.
That feature would result in my getting tickets for rolling stops.The cars that have the feature are constantly monitoring multiple parameters. It definitely knows the battery reserve - also monitors engine temperature, ambient temperature, cabin temperature, climate control settings, etc. My Audi won't do the start/stop thing unless the engine is warmed up and stopping the engine won't cause the cabin temperature to dramatically change during the duration it is engaged. Having said that, I live out in the country and having the engine stop every time you come to stop sign or flashing red light where you are only going to be stopped long enough to look left and right is painful.
I have no issue with it when it works perfect, I've had it in a couple of rental vehicles, my sister just bought a Grand Cherokee with it.I have the start stop technology on my F150. There is no delay at all. It starts instantly when you take the foot off the brake. By the time you get the foot to the gas pedal, it's ready to go.
You mean like dumping it down the exhaust to burn off soot in the DEF? I'm not sure the EPA would allow intelligent minds to come up with better ways... Personally, I'm keeping two vehicles that are so old that a electromagnetic pulse attack wouldn't do anything more than cause some static on the radio.There has to be better ways to save fuel.
So one would think that the OEM one should be the cheapest, their certification costs would have been completely amortized when factored into the truck cost being produced at the time when they designed it. They just have to crank out more to supply the replacement market now. So once again, the Green movement spells a major opportunity for "green" for the manufacturer.The cost of replacement cats isn't the materials - it's the certifications to prove to the gubmint that it actually works the way the original did.
Good theory, but I don't think it works that way. The OE (assembly-line) parts are certainly certified. But I don't think Ford allows their suppliers (OEMs) to use the designs & certifications that Ford paid for to churn out replacement parts free - I assume the mfr. still has to either license the design from Ford and share those profits, or come up with a new design (aftermarket) that's a direct-fit, and have that certified.So one would think that the OEM one should be the cheapest, their certification costs would have been completely amortized...
