Today we will talk about the Start Stop System, which is a system designed to make the optimum use of the fuel in Start-Stop conditions. In 1980s Volkswagen Polo and the Fiat Regta were the first cars to flaunt this new technology which forwarded to Volkswagen Golf in 1994, VW Lupo and Audi A2 3.0 L. Though initially the technology failed to impress many drivers due to its high cost, it was later accepted whole heartedly.

Talking about the Indian manufacturers, the Mahindra & Mahindra has used this technology in Mahindra Scorpio, Bolero MaxiTruck and will soon re-introduce it through its to-be launched Mahindra Xylo Micro Hybrid


What Is Start Stop System?

The Start Stop system is based on a simple principle of not burning the fuel when it is not required. The system automatically detects occasions during your drive when the vehicle is idle & stops the engine thus conserving fuel. Thus it aids in attaining better fuel efficiency & reducing running costs.

How Start Stop System Works?

  • Vehicle has come to halt due to traffic signal/jam, is in neutral gear.
  • The engine will shut down automatically after 10 seconds. Just before stopping, the indicator in the cluster will blink indicating the engine is going to stop shortly.
  • The indicator will glow on your instrument cluster indicating the engine has stopped due to stop start device.
  • Once the Signal turns green, press the clutch pedal & engine starts immediately.
  • The indicator on the cluster goes off indicating that engine has started again & you are ready to drive on with the vehicle.

A few lakh rupees. The technology certainly has value for money and do hope that other brands consider it an important part for their products as well.

  1. Where can I get this (start and stop system), will it be available with my car dealer? will they be able to fit it into my car?

  2. what if the car is descending a hill.. in a neutral gear..
    this device will stop the engine and if there’s a sharp turn ahead or a possible obstacle.. the driver won’t have the time to react?
    this tech will work only in city conditions, right?
    if no..
    plz explain in deep.

  3. @kaddy
    I guess engine is turned off only when car is not moving, another thing, please never drive in neutral when going downhill, it can be really dangerous anyways, you should try using some optimum gear with clutch fully released. It will help in slowing down the car more quickly when you release the accelerator (engine braking).

  4. What if I want my car to be turned on in netural gear..
    for instance im sitting in my car, putting my AC on…??
    den what??

  5. I would like to know if the technology -Start Stop system can be fitted in my Wagon R. f yes, How much will it cost –


  6. during starting also the engine takes more fuel, so on city traffics, is that a better idea to stop and start continuously?

  7. Agreed with Sudeesh,
    An engine needs more energy for start/stop rather than letting it idle for just 10 more seconds. Also, I do not want my AC to go off in sweltering summers of India or the CD player to reset the song.
