    Closer Look at Start/Stop Technology

    Looks like we will see this in 2018. I wonder how it will effect the hotter climate owners and use of AC.

    I also can't attach a You Tube video. I try and it just sits there and will not post it. Any idea's?

    Some of the new fords have this as well. My only problem is that (at least as far as the Ford start/stop goes) is that you no longer can control your steering wheel while the cars in 'stop' mode. I can only imagine left turn accidents due to it...

    But if they can get it right, hey - better fuel economy is great!

    The new 1.6T engine that Opel designed is a start/stop engine. As long as you have electrical power, the Cruze will turn it's wheels relatively easily. Our steering is electric.

    It's freaking annoying in most cars. If I'm not driving a hybrid, I'll shut my engine off, thank you very much.

    My friend has a 2005 V6 Hybrid Accord - essentially a start-stop "mild hybrid" system that can run off 3 cylinders and engages the engine as soon as you let off the gas. Honda did something BRILLIANT and ran an electric variable displacement AC compressor. When the engine shuts off, it kicks the compressor down to a lower displacement and keeps running the AC. Airflow is a bit reduced, but it still stays cold.

    ...they're assuming (emphasis on 1st three letters!) the engine instantly restarts every time...ain't gonna happen as engines accumulate miles, age, wear & tear...especially in colder climates.

    ...totally DUMB approach in DESERT locations (>100F) where A/C already (where is R22 Freon when you really need it?) is lousy and gets worse at idle?!?!

    Even R22 struggles in my home AC in the summer here when it's in the 90s. "Oh yeah, it's working fine. Everything checks out." I'm pretty sure it shouldn't be losing a battle when the thermostats at 74 and it's 77 inside.

    I miss good old R12. You could freeze meat on the AC vents in my house growing up 20 years ago.

    Electric steering should cure this problem?

    Most start/stop systems include the ability to get the car moving from a stop while the engine is restarted. Basically it replaces the car's 1st gear.

    Yes, because it can still produce pressure without the engine running unlike a engine driven pump.

    The stop/start in a friend's 2005 Civic Hybrid works just fine 8 years later.

    EPS is great since it uses a electric motor for assist, not an engine-dependent pump. So it's possible to have some assist with the engine off. Our Cruzes don't, though. The steering is feather-light at speed anyhow, so it's not a big deal.

    Learn from the mistakes of others, so when you err it can be in new and interesting ways.
