I'm not a fan of these systems, mostly because my air conditioning stops or slows down when the car turns off and it's almost always needed where I live. They are fairly undetectable otherwise in most new cars that have them and I really can't see a safety concern. However, those systems can usually be turned off if you prefer each time you start your vehicle. With regard to motorcycles, I'm not sure how they would be able to work with a manual transmission. So, unless the market is moving towards mostly automatic transmission motorcycles, I don't think we'll have to worry about it for quite a while.

My safety concern primarily has to do with such devices on motorcycles, not cars. However, I agree about the air conditioning problems that would occur in warmer climates. Where I live in Texas, air conditioning can be needed from February to November.

I find the concept of sitting on a dead motorcycle in traffic to be rather alarming and definitely not safe.

 

Mine turns back on when cab temp gets higher than set.......wife's car is the same, both 2019 Ford

 

Well, in the never ending sun of Southern Nevada, that would mean the car would never turn off. But they do. Including my brother's brand new F-150. It's just so freaking hot here, and even when it's not, the sun is so intense that the cabin heats up instantly.

Then hit the button that turns the system off

 

Those systems must be hard on the starter motor.

 

One would hope they redesigned the starter in a car to survive this, but who knows.
In the motorcycle system described in his article it's different, not using a conventional starter but using the generator to also crank the motor, it's interesting, check it out.

 

Those vehicles still annoy me when I get them in the shop.

I've noticed features on new cars can be turned off, but several features have to be turned off everytime the ignition key is cycled.

Even my AT is affected by that. Torque control can be turned off, but it's on after ever ignition cycle. I can however leave it on its lowest setting in a user program mode, so that my 'work around', close enough to off as I can get it.

My pickup has a Park Assist feature like that. I hate it. I wish I could make, off, unless I turn it on instead which I'd never do so, off, permanently would be fine. I'd remove the fuse if it didn't affect something else.
Then you also have some 2 cylinder bikes that turn the rear cylinder off at stops. I don't much care for that either.

 

I've barely heard of start stop systems on cars/trucks. You stop at a red light and your vehicle engine can automatically stop. The idea is to save fuel. When you take your foot off the brake or press the accelerator, the vehicle immediately re-starts. Hmmm.

Now in a thread on this forum (See Post #7) there is a mention of a motorcycle start stop system, although apparently not much in the USA as of now. Here's an article about the Honda system: Honda system

Maybe I'm stopped at a red light on a start stop system equipped bike. I've picked out a spot to move to if somebody behind me fails to notice the red light and the brake lights on my bike and is going to run into me. The car approaching me has a driver checking phone messages and is about to hit me. Will the start stop system give me enough time to move and stay alive? Hmmm.

That would be a concern unless it started up really quickly, I'd have to see it in action.
I think this might be more practical on a hybrid vehicle that gets going on battery as the engine is starting. Hmmm.. I've seen plenty of electrics but have there been any hybrid motorcycles? That might be interesting...

 

The danger of such a system on a motorcycle should be obvious but then we are talking government regulations, and in the never ending quest to make everything compliant with economy and being green, the safety of some of these ideas do not seem to have been part of the equation. As someone who does a lot of driving with many different vehicles each day I can say there are many that do have the button to turn that system off, but there are those that do not. I have found if I am coming to a stop, red light, if I nudge the shifter into neutral just before stopping, or brake the vehicle in such a way as to have almost no pressure on the brake system but just enough to hold the vehicle in place, the engine will not stop. Or if while sitting at the red light, quickly take your foot off the brake pedal and then press it back down, the engine will immediately restart.

 

Current versions are better than the Cadillac 4,6,8 of the 80's

 

Thats not saying much

 

The 8-6-4 was while moving

 

And it was a POS

 

Most people had that system locked out so it would only stay in V8 form.

Depending on electronics is never a good thing.

 

I know what you mean but the reality is that I don't think there has been a car or motorcycle built in the last 40 years or so that doesn't depend on at least some electronics to run.
My 1978 Honda which will kickstart and run without a battery still has a very basic electronic ignition, I think it's the first year without points, so that's about the cut off year.

 

If they had 2 engines in there and they only kept spinning one of them it would work. Shutting down a cylinder and still spinning it at thousands of rpm using the other cylinders that are still working, that's just silliness.

" he sued GM
over the problems. Never did find out how he made out." they went bankrupt didn't they.

 

.... Shutting down a cylinder and still spinning it at thousands of rpm using the other cylinders that are still working, that's just silliness....

My 2017 Corvette will go into a 4 cyl mode when I have the car in "Eco" mode (which is like, never) and there is low demand on the motor. It does work. On the couple of longer freeway trips I've taken in it, 7th gear and Eco mode produced spectacular gas mileage for a 465 HP, 6.2 L V8.

Big Honda generator and electric motors on every wheel, then you can have the worlds only all wheel drive electric Vette that runs out of gas after 8 hours

 

The early versions on cars were a bit dangerous as you had to turn the key to get it started but my x just bought a Honda CRV I think it is and to start you just take your foot off the brake and press the accelerator. It adds about 5mpg in the city

My new scooter has it and instead of regular starting that has to be done with the rear brake pressed all you do is turn the throttle so it is slightly quicker response than starting with the engine cold. I like the system.

Opinions vary

 

Neighbour down the road has a Prius. Gas and electric motors. Adds about 100 mpg around our Island and in the city. UK
