    GM to Offer Stop-Start on Most of Their Lineup By 2020


    • Your future GM vehicle will likely have a Stop-Start system

    General Motors is planning to expand the use of start-stop systems across most of their range by 2020 in an effort to improve fleetwide fuel economy. The plan will see at one powertrain combination offered in a vehicle to have this system. Stop-start systems work by turning off the engine when the vehicle isn't moving. When the driver removes his/her foot from the brake, the engine will kick back on.

     

    This move comes as the EPA will start handing out credits towards compliance with corporate average fuel economy standards to automakers who use this system in their vehicles next year.

     

    "Everyone will end up adding start-stop. Now there's a benefit in the EPA cycle, which there wasn't a few years ago. GM's new nine- and 10-speed automatic transmissions have been engineered from the beginning to incorporate start-stop. That will make it much easier and much smoother. That's what's been the holdup. First it was a regulatory issue, then it was a hardware issue," said AutoPacific analyst Dave Sullivan.

     

    GM spokesman Tom Read tells Automotive News that vehicles equipped with the stop-start system will use absorbent glass mat batteries (AGM) and tandem solenoid starters to enable faster and smoother restarts.

    a friend took me in his 14 malibu for a ride and it had start stop......worked pretty well.  

     

    All that said, I WANT A SWITCH TO TURN IT OFF IF I WANT.....

     

    reasons- 

     

    winter (i don't care that it turns itself off at a certain temp)

    when your car ages and may have trouble running, why would you want something that deliberately shuts off the car

    continual stop and start is hard on vehicle components and fluids, turning off start stop would reduce wear

     

    Not being able to turn off the start / stop = federal overreach

    Your final point about reducing wear is exactly backwards and out of date. The GM system keeps the oil pressurized, The engine fires nearly instantly with direct injection, and in the case of the BAS system, the regular starter is not used.

    Wonder how well it will hold up over time...

     

    Thinking it should last 200k like the rest of the car....

     

    In the eAssist systems, it's just a giant alternator that can also be a 15 horsepower electric motor, attached to the crank pulley via a thicker than normal serpentine belt.  The technical difference is so minor..... it's nothing to worry about.  The current start/stop system is just the old eAssist system with a smaller battery and smaller alternator/motor which doesn't assist the engine during acceleration.

     

    Given all of GM's other troubles over the past 10 years, the fact that we've heard basically nothing bad about the reliability of eAssist should tell us something. 

     

    That said... this announcement sounds like a different setup than the eAssist in that it runs through the transmission instead, making it more of a traditional starter.

    That is very good to know.

     

    Although I would still appreciate a switch to be able to turn it off. And if the system is as seamless as they make it sound, then I'll never turn it off.

    It takes about half a day to get used to it.... and that was even on the jittery Benz version.

    same here, it should be user control.

    Let me make this clear from the start I am not a fan of the start stop.  I too wish for a delete button. 

     

    Now let me get to the truth about the system. GM has one of if not the best system out there. It is smooth and is pretty much not noticeable unless you really are looking for it. [Even I have to admit my reluctance is petty] 

     

    The cars today get up to temp in the matter of a mile or so and will get to temp even faster moving ahead. Fast warm up is key to lower emissions and that is a focus of all companies. 

     

    The system has proven durable in the older cars and trucks with it. While rare they have not seen any major issues. 

    Wear is a falsehood by those who really are not up on the system or systems out today. 

    The delete button is much like the Skip shift. It has to be on full time to be considered by the EPA to get the MPG listed. Now with that said I would not be shocked if Jet or Hypertech may make a OBDII plug in that may defeat the shut down if you so choose. GM will not fight them on it in the aftermarket. 

     

    The only real negative is if something does go out it could be a bit pricey to replace but on today's cars most things are pricey. But even then how often have you had to replace a starter lately. I have had going on 30 cars over the years and only had two go out on late 68 and 70 Chevy. 

    It has gotten to the point where cars may run longer but when they do wear parts out their worth is less than the value of a change of a cam belt or other mechanical issue anymore. I suspect the used car market may be in for some changes with high mileage hybrids and higher tech cars in need of repair. 

     

    Many will be parted out and may lead to even more salvage parts being sold by dismantlers.

     

    As for the stop start it is seen where most companies will have it on 75% or more of their cars from most MFG. The deal is you are going to get it no matter if you like it or not.  

     

    At some point these will become the norm and we may notice more the cars that do not shut off than the ones that do.

    Yeah, kinda what I figure as well. GM does not always tend to be on the forefront of stuff, but tends to make sure it is right and solid when it comes out....

    yup, and despite all that, like a traction control switch, it still would be desired to have the control to turn it off.

    I am so glad the 2016 Spark has a switch to turn off the traction control to enable more epic burnouts and a better chance of continued forward motion in deep snow, sand or mud.

    I would definitely weigh it as a negative in any future purchase.

     

    Well by then it will be like Seat Belts as you may not have many options otherwise.  

     

    This is an industry wide deal and it is going to be found nearly everywhere.

    The bottom line is legally they will have to have it with no defeat switch to count as a EPA boost to MPG. 

     

    No different than the skip shift on the Vette. 

     

    Now I can see a plug in for the OBDII that could disable it. The after market will provide what the MFG can not do. 

     

    In other words don't get worked up over it as there will be a work around. Besides by the time you buy one they may be very common and well sorted. I hate it too but I have seen these dilemmas come and go many times. 

    Good god the people got their panties in a wad over cars with Fuel Injection when it came out. It was Oh my god we will never be able to modify them again. Well Look around now.

    I hope there is an off switch as well.

     

    These are good for time you sit a long time at a red light, or sit in a fast food drive through or something like that when you are doing mostly sitting.  But they they start shutting the ending off for 2 seconds at a stop sign they get annoying.

    I had a '16 Malibu in Ohio last week, the start/stop was pretty smooth and unobtrusive.   Though in really hot weather it would be annoying to have the A/C cut in and out.

    On the Malibu, if you set the AC to Max, the Start/Stop will be minimized

    Good to know. I was never able to shut off the ventilation completely. I could set it to floor or dash vents or both, but never neither. But that's another issue...

    The AC in the stop starts I have been in never were an issue. The only real noticeable thing was the tach dropping and a little jump on start up that is no longer an issue. 

    The first one I drove on a truck I was expecting it to feel like the car stalled and it never did. That was long ago too and the newer systems are much better and only getting better. 

    Like I said I am not a fan but I can not bad mouth it because it does work.

      200 MPH plus EV, Do we care?
       
      Yesterday April 13th 2017, Lucid sent out an email about how their near production test car hit a top speed of 217 mph at the Ohio's Transportation Center banked oval test track. Many of us that follow the industry know that Tesla limits their auto's to 155 mph.  Lucid is on record that they intend to meet the needs of the high-speed cruising market of Europe and Middle east. Simulations can only go so far on a computer and then you have to put rubber to the road. This allows the engineers to monitor and tweak everything from the power train, suspension, body fluidity and so much more. This will allow them to review the data, make adjustments and come back later to push the limit even higher.
      We know that Lucid is planning on a $60,000 dollar 400hp, 240 mile range RWD EV with the top model being a six figure AWD 1,000 HP and 400 miles of range on a super dense battery pack.
      This begs the Question, other than the few places you can push this kind of Speed, Does it matter any more if an auto can go over 100 plus mph?
      This question comes from seeing so many auto's that are now breaking that 6 second 0-60 speed showing they have the torque and hp to maintain the speed needed for daily driving.

      There are still a lot of unanswered questions concerning the sale of Opel/Vauxhall to PSA Groupe. A fair number deals with Buick as a number of their products (including the new Regal) are intertwined with Opel. GM executives say this will not affect Buick's lineup down the road.
      “The sale of Opel will have no impact on the fresh new lineup Buick is building out,” said Duncan Aldred, GM’s vice president of global Buick and GMC during the launch of the 2018 Regal this week.
      “This is very much part of our portfolio plan,” said Mark Reuss, GM’s executive vice president of global product development, purchasing, and supply chain to Car and Driver. “As we said, Opel and the engineering/production piece of this is very much intact for all of our global platforms. So, you know, no impact.”
      While the deal isn't fully finished yet, Reuss claimed that issues relating to products would be settled before the final transfer takes place. Reuss said he didn't know "of a specific agreement" when asked about if GM would pay PSA Group for engineering work done by Opel. 
      In related news, Automotive News Europe reports that Opel would continue to build Buick vehicles beyond 2019 in its German factories.

      Last week saw the PSA Group (parent company of Citroen and Peugeot) purchasing Opel and Vauxhall from General Motors for $2.3 billion. This move would make the PSA Group the second-largest automaker in Europe. We already know some of the plans that PSA Group has for their new brands such as setting operating profit targets of 2 percent in 2020 (jumps to 6 percent by 2026) and the next-generation Opel/Vauxhall Corsa being the first new product developed with PSA. But as we alluded to in the original news story, there are a lot of questions that remain unanswered such as possible job cuts or what happens to Buick and Holden as they share products with Opel. I have been doing a bit of thinking on these and some other questions. The end result is this piece.
      1: Will there be job cuts and plant closures?
      In 2016, PSA Group employed 172,000 people worldwide. With the acquisition of Opel and Vauxhall, they will be adding close to 42,000 workers (the majority of those from Opel). The number of plants will also increase to 28 due to this purchase. Sooner or later, PSA Group is going have to make cuts. During the press conference announcing the deal, PSA Group CEO Carlos Tavares said the company “would honor existing labor agreements and closing plants is a “simplistic” solution.” That may be true for now, but this might change within the coming years. Some analysts believe PSA Group will close two to three plants within five years.
      The most likely place where the closures and layoffs could take place is in Great Britain. The reason as we talked about in a story back in February deals with the decision made by British citizens last year with leaving the European Union.
      “By leaving, the country would lose access to the EU Single Market which guarantees unconstrained trade across the member states. It would mean various countries would be leveraging tariffs on British-made goods, making production in the country less competitive.”
      Former British member of parliament and business secretary Sir Vincent Cable outlined how bad this decision looks for Vauxhall in a recent interview on BBC Radio 4.
      There could be a way that the British Government could at least stall the possible closures. Back in October, the British Government worked out a secret deal with Nissan to keep them investing in British car production at their plant in Sunderland. This deal caused an uproar as the details were kept as many believed the British Government would be handing over money to keep Nissan happy. But sources told British newspaper The Independent back in January that the deal had no mention of money.
      It could be that the British Government could do something similar for PSA Group to keep jobs, but it is too early to say if this will happen or not.
      2: Will this affect PSA’s plans of entering the U.S.?
      Probably not. Let’s remember that PSA Group is working through a ten-year plan that may or may not see the return of the Citroen and Peugeot, along with the introduction of DS to the country. Already, the first part of this plan is gearing up for the launch of a car sharing service next month. There is also extensive research going on into the U.S. marketplace. 
      But could there be a possibility of Opel or Vauxhall vehicles being sold here? It would not be surprising if there isn’t talk about this at PSA Group’s HQ. But there is a slight complication to this idea. As part of the sale, PSA Group cannot sell any Opel vehicles developed by GM anywhere in various markets outside of Europe (China and U.S. for example) until they transition to PSA platforms. That means a number of models such as the Astra, Insignia, and Mokka are out of the question for the time being. If Opel was chosen to be one of the brands PSA would sell in the U.S., they might not have a full line of vehicles to sell due to this clause.
      3: What does the future hold for Buick and Holden?
      If there are some losers from the sale of Opel, it has to Buick and Holden. Buick has found some success with Opel products as the Encore (rebadged Mokka) has become one the best-selling models for the brand. Holden is getting a shot in the arm as the Astra will hopefully help their fortunes in the compact space, and the new Commodore (rebadged Insignia) has a tough task ahead of it with living up to an iconic name. For the time being, Opel will continue supplying models to both brands. It is what happens in the future that many are concerned about.
      During the Geneva Motor Show, GM President Dan Ammann said something very interest to Australian journalists about the future of Holden’s products.
      This makes sense as the Astra was only launched and the Commodore is getting ready to go on sale. But I wouldn’t be surprised if talks begin very soon about this very topic. The same talks are likely to begin at Buick soon where they face the same issue for the Regal and Encore. Our hunch is Buick might have the easier time of two. The Encore would continue on since it shares the same platform as the Chevrolet Trax. As for the Regal, it could leave Buick’s lineup once the next-generation model runs its course.
      4: Does GM lose anything with this deal?
      There has been a lot of talk about how much money will be freed up from the sale of Opel/Vauxhall for GM, along with making a bit more profit. But it comes at a cost that could hurt GM down the road. The recent crop of compact and midsize sedans from GM owe a lot to Opel’s engineering knowledge. Vehicles that excel in driving dynamics and fuel economy are worth their weight in gold when it comes to the European marketplace. As we know, one part of why GM went into bankruptcy was the lack of competitive small and midsize cars that got good fuel economy. Opel would prove to be GM’s savior with this key knowledge.
      Right now, compacts and midsize sedans aren’t selling as consumers are directing their attention to crossovers and SUVs. This is due in part to lower gas prices. But sooner or later, the price of gas will go back up and cause many to go back to smaller vehicles. With talk about GM scaling back on their small and midsize car lineup, this decision could have consequences down the road. Plus with Opel out of the picture, GM doesn’t have someone it can rely on to get these models back to the forefront. We can hope GM’s North American office has learned some stuff when working with their European counterparts.
