Every day’s journey is short or long, the real concern is mileage. Traffic has to stop again and again and every time the engine is running, the fuel is wasted. Hero’s i3S Start Stop System has brought a smart solution to this problem. This technology not only improves mileage, but also helps reduce daily spending gradually. So let’s understand how it benefits.

Hero i3S Start Stop System

The full name of the i3S developed by Hero MotoCorp is the Idle Stop-Start System. Its purpose is to prevent fuel waste. When the bike stops for a few seconds in a traffic signal or jam, this system automatically stops the engine.

As soon as the clutch is pressed, the engine immediately resumes. The engine turns on as soon as the throttle rotates in the scooter.It all happens in such a smooth way that the rider does not feel up to the shock. As if the bike itself is understanding when to relax and when to run.

Mileage

Even when the bike is parked and the engine is running, petrol continues to be burned. This is the biggest waste. The i3S system cuts off fuel supply to the engine during idle mode, preventing unnecessary consumption.

This technology proves to be very beneficial in heavy city traffic, where frequent stops are necessary. For those who commute to work daily, these small savings become a significant relief at the end of the month.

Real-World Mileage

Mileage in the real world depends on many things. Traffic, riding style and road conditions. But bikes that get i3S technology, such as Hero Splendor Plus, have 60 to 70 kmpl or more on-road mileage seen in the city.

This figure is felt not just on paper, but in everyday life. Especially when one has to stop at the red light several times every day.

Daily Commuters

If you have to travel 15 to 25 kilometers daily, the i3S system can save a lot in the long run. Think how much fuel saving will happen by keeping the engine off for a few minutes every day. This difference starts to look clear throughout the month. This savings can reach thousands of rupees throughout the year.

Technology

The good thing is that the i3S system is absolutely easy to use. It is also given the option to turn on or off, allowing the rider to control it as per his convenience.

There is no complicated process, no extra hard work. Just ride the bike in the normal way and technology will continue to do its work on its own. In today’s era, when everything is getting smart, it is also important for the bike to be smart. i3S is a strong step in the same direction.
