Auto Start/Stop Coming to US MINIs

According to sources inside MINI familiar with future product features, the US market will finally see an auto start/stop system for both manual and automatic transmissions. The first version of auto start/stop made a European debut in 2007 and since then MINI USA has been interested in adding the feature to US bound cars.

The reason for the delay is two fold; there’s been little incentive since the EPA doesn’t recognize such systems in an overall efficiency index and the bigger concern is that the system isn’t free. Again, according to those same sources it adds over $200 per car, thanks to the beefier starter motor, the added electronics and programming. MINI USA couldn’t absorb that cost and didn’t want to pass it on to the consumer. But as BMW has moved to add the technology to almost it’s entire fleet, that price is rapidly decreasing as volume of the system is increasing. Likewise things are changing in the US that make the technology more relevant to the way the EPA measures efficiency- there is an added benefit to automatic transmissions with the current EPA test procedure. This makes a much stronger argument for bringing the system stateside.

We expect the system to debut with the next generation MINIs – the first (the F56 hatch) set to debut in the fall of 2013 as a 2014 model. After that MINI will roll-out other derivatives (the five door hatch, the convertible, Clubman etc) that will all share the technology. Other MINI models such as the Countryman should see the system added over the lifecycle as well.

The system will work identically to the current set-up, which is the second generation of the system. On the manual the Auto Start/Stop function switches the engine off automatically when the car comes to a stop, such as at intersections and in traffic when the car is placed in neutral. When the clutch is depressed to shift into a gear the engine reignites. The manual setup will also feature a shift point display in the cluster that advises the driver of the most efficiency-enhancing moment to change gear and the proper gear to be selected.

On the automatic, the system engages (ie the engine turns off) when the driver comes to a complete stop while in “D” and pressure is applied to and remains on the brake. To start the car again the driver simply lifts their foot off the brake (as they would normally) and the engine seamlessly engages.

The system protects the engine by not allowing the start/stop function until the car is up to proper operating temperature. Likewise it won’t engage if the ambient temperature is too hot or cold or if the demands of the climate control are not being met. The system is able to be turned off manually, detects stop and go traffic (disengages) and can be overridden by turning the steering wheel or relaxing pressure on the brake pedal.

It seems all a bit backward to US that the EPA hasn’t had the forsight to change it’s system of measuring to include such systems. It’s pretty clear that auto start/stop saves fuel (and potentially a lot of it) in commuting situations. It’s nice to know that MINI will finally be taking the initiative (as BMW has). We have long term experience with the European version of the system and have seen the fuel economy gains.

    is there a detailed explanation on how exactly this works? I can’t imagine my engine having to restart 20 times during a short stop and go commute in NYC. how is this a good thing again?

      It saves a not insignificant amount of fuel.

      The system only kicks in under certain circumstances. For example, if you come to a stop light, put in the clutch, shift into neutral, then let off the clutch, the system will shut off the engine. Put the clutch back in to shift into first and the engine will have started again before you finish shifting and are ready to move. Meanwhile you weren’t idling that while time. You can also turn the system off.

        how does it know when to do it on an A/T car?

          Aurel – explained in the 5th paragraph down in the article. I had a Honda Civic hybrid loaner once with the auto start/stop and it was pretty seamless. come to a stop, it shuts the engine off, take your foot off the brake and it starts right up.

        • Aurel

          thanks. i missed that. not sure how this is a good thing though …

        • BimmerFile_Michael

          In city driving it saves a good amount of fuel. We have had the system in our cars since we moved to Germany last year and we have run the numbers and for something that is truly non-evasive and that does not impact performance one bit it saves a good 3-5% of fuel which is truly savings at the pump here and it helps emissions as well.

        • http://www.facebook.com/people/Scott-Eaves/100002517570191 Scott Eaves

          For probably the first time ever, I’m in agreement with you. I’m glad it’s coming to the US. This will definitely help save on fuel.

        • BimmerFile_Michael

          @facebook-100002517570191:disqus See there is a first for everything! All kidding aside, I think you may have agreed with me more than you think ;)

    • Mysticeti

      This sort of tech has been used for many years in hybrids and I’ve yet to hear of any complaints. Far from it, the additional peace and quite is most welcome (in addition to the savings at the pump).

  • AstonM

    What happens to your a/c? If you are in stop-and-go traffic in PHX AZ for an hour, where reported temp is easily 118* (higher on the highway in traffic for sure,) what is going to happen to the cabin temp of your car? It’s a challenge for a passenger to wait in the car long enough for a petrol fill-up with the engine off around here, let alone face an afternoon commute without a/c. I really hope no one gets the bright idea to make auto start/stop mandatory.

    • les

      In our BMW, if the temp is over 90 the auto stop start won’t shut the engine off. If below 90 then the engine shuts off, everything else stays on. The a/c continues to blow, but it’s not cooled. Tolerable, but not cooled.

    • BimmerFile_Michael

      Not be a a pain but if you read the post it would have answered your question…

      “The system protects the engine by not allowing the start/stop function until the car is up to proper operating temperature. Likewise it won’t engage if the ambient temperature is too hot or cold or if the demands of the climate control are not being met. The system is able to be turned off manually, detects stop and go traffic (disengages) and can be overridden by turning the steering wheel or relaxing pressure on the brake pedal.”

  • otter

    I have seen override devices that claim to disable the start/stop in a manner that eliminates the need to deactivate it every time you start the car (assuming even that will be an option). Provided that a device like this actually works and doesn’t cause issues with the car or its warranty I guess I could live with start/stop being on the car; however, if it is not possible to disable the system in a manner at prevents it from coming on every time I start the car it becomes a deal breaker for me.

  • 2013 JCW

    So the 2013 JCWs won’t come with auto start/stop as mentioned in the World Premier: 2013 JCW MINIs on May 18, 2012?

    Off-topic-is Bimmerfile still up and running? No new articles in 2 weeks it seems.

    • http://bridger.us/ Gabriel Bridger

      Odd – we’ve had stories everyday since them. Can you tell me what you’re seeing and what on?

      • Hoover

        I noticed this, too. When you click on the link from the MotoringFile page to the BimmerFile page, it goes to a story from July 31. I refreshed and nothing happened. I typed in http://www.bimmerfile.com and the new posts showed up. Weird.

    US backwards about new things? Shocking!
