Dodge Charger police car – Click above for high-res image gallery

Let's face it, for most police cruisers it's a hurry up and wait kind of existence. A study by the police in Ottawa, Canada found that most cruisers sit with the engine idling for about 6.7 hours out of every 10-hour shift. The problem is that modern police vehicles are crammed with gear like radios and computers and also need working climate control systems. As a result, it simply isn't practical to shut them off all the time because they need power. Of course, more of the time, the cops also don't need the full power of a running V8.

The Ottawa police installed anti-idling technology in two patrol cars for a year-long test and found that fuel consumption was reduced by more than 10 percent. These weren't just basic start stop systems like those found on many European cars. The $2,000 system includes auto-shut-off for the main engine, extra batteries to operate the electronics and a small engine for heat and charging. Considering the low mileage that operational cruisers are likely getting, the 10 percent savings adds up to a pretty significant chunk and the payback takes only 18 months.

      The prime reason CO2 emission rights are just 15 Euro/MT: there is so much potential for low cost projects like this. Unfortunately, EV's don't qualify yet (ever?).

      OT: the Dutch highway patrol used topless Porsche 356/911's, and appropriate clothing. Because those cars were capable of driving in reverse for miles and miles without overheating...

      Sounds like a step in the right direction, but they really should ramp up hybridizing cruisers. That would save fuel while stopped and while cruising around.

      I don't see a downside to hybrid systems other than cost; they can often times perform better than their ICE counterparts, and they eliminate idling while still providing ample power on tap.

      I'm surprised the Ottawa Police had the brains to tryout a system like this but not to be aware of the new license renewal process of the MTO.

      This doesn't make me like them anymore =)...

      Or, at least use Stop/Start technology.

        Start stop alone won't do much of anything for the police. They NEED to have the vehicle running at idle in order to power all of their electronics...having additional batteries or a generator that consumes less fuel and emits fewer emissions would be a step in the right direction.

      Havis, which is the manufacturer of the partitions in police cars and other equipment, makes a product like this called the Havis IdleRight. It's also under $700 for the module and wiring harness.

      You guys know if there's a diy kit for stop start tech? 90% of my driving is mostly city (for now, until i get this career of mine). I wanna put it in a honda fit.


      No, I don't want a prius, I want to own something and I don't want to keep a prius for more than 5 years.

      I work on the railroad and NS has installed engine shut off devices on many locomotives. If the train doesn't move for a specified amount of time the engine shuts down.

      Why only 10% saving??

      If they idle for 6.7h a day, you'd think they save at least 25% no?
        • 4 Years Ago
        I'm surprised it's as high as 10%. An idling engine shouldn't be drawing much fuel.
      • 4 Years Ago
      Reduces emissions, saves fuel, payback time in just 18 months, and apparently it's a fairly simple retrofit ... seems like a no-brainer to me.

      I was wondering when somebody would finally start paying attention to this. Hybrid cop cars for this exact reason seemed like an absolute no brainer to me. I wonder what they used for the engine and for the battery? I'm guessing it's just a deep cycle lead acid or something.

      I see. That's actually a pretty smart idea, if not a little ghetto-rig. Much better to idle 1 or 2 cylinders than 8... :)

      Who had the brilliant idea to park the police car in front of a donut shop?

        Or in a handicapped space.
