The use of start-stop technology is now available with most new cars and is a prerequisite on eco-friendly models. These systems are occasionally called “micro hybrids” due to their minor fuel saving capabilities. Valeo, one of the companies producing this system, has announced that they will be fitting their second generation start stop technology in PSA Peugeot Citroen group cars by the third quarter of 2010.
This new system is branded “i-StARS” and can be fitted on both auto and manual transmissions. Unlike previous versions of the start-stop system, the system can now cut off the engine even before the vehicle comes to a complete stop, so you can coast to a stand still in silence without burning any fuel. The maximum speed for the system to kick in is anything below 8km/h for auto transmissions and below 20km/h for manual transmissions.
Apart from that, engine re-starts are supposedly “noiseless and with no vibrations” and are effortlessly done in 400 milliseconds. This naturally increases fuel efficiency and reduces CO2 emissions by up to 15 per cent in heavy traffic.
Making it more flexible in its application within different car models, Valeo will offer i-StARS in two variants which would either be the starter-alternator or reinforced starter-based system. This strategy has secured them orders from 10 automakers to fit it within 50 vehicle models.
Valeo plan to fit 1 million Citroen and Peugeot vehicles with their technology by 2013, so don’t be surprised to see the technology in your new Peugeot sometime soon.
Looking to sell your car? Sell it with Carro.
hmmmm…I’m sure they would have thought about it but….
Not having brake servo assistance when cruising to a stop…big hmmmmmm…..
I can understand shutting down individual cylinders but whole engine when the car is still moving??
I wonder how a Prius deal with its brake servo? has an electric servo?
at 8 to 20 km/h you dont need any servo assisted brakes…
THis is really good~~!
Good for the environment ; )
This is creating another problem to solve another problem. Just spend all the money finding a better way to travel will make much more sense than all these.
Couldn’t agree more, it’s even better to spend time n money think of how we should change the way we live in Earth, do we really need to travel to work? Is there a way to design a city without ‘road’ ‘highway’? Of course, they are motivated to design the stop/start system simply for money n business in the name of eco-friendliness.
why did they killed the electric car in the 1930’s anyway?
Hi Jacob,
Don’t think it will reach our Pugs… it has been announced only for HDi versions…

So think you should take that last line out unless you have some insider info that is not published elsewhere…
Mazda i-stop is more advanced than this…
I wonder if it will affect the braking capability.
not really useful in hot climates like Malaysia. We need the aircon running while we are stuck in traffic jams…
what about power steering?
