idle stop systems save fuel by shutting down a vehicle's engine automatically when the car is stationary and restarting it when the driver resumes driving. Especially in urban areas, drivers often let their car's engine idle at traffic lights or when stopped in traffic jams. Switching off the engine to stop it idling in these situations enhances fuel economy by about 10% under Japan's 10-15 mode tests*1.

thats all fine and dandy when the car kicks on while its fairly new and tuned.. imagine that after its like 10 years old and all outta wack.

It'd have the get up and go of a s5 N/A with its 6ports out of wack, exhaust out of wack, spark plugs out of wack, ect. ect.

i think you are supposed to lease cars like that

EW LEASING..

actually i betcha it would turn into the idling stop system. it just wouldnt restart...

lol

meh shut it down to one-cylinde ror something, dont stop all the motion, plus doesnt it use more gas to fire up the engine then to idle it?

It doesn't for a diesel though....and somehow back in the 90's that pertained to a gas engine somehow. However the prius/insight both have systems that shut off the motor whilst sitting still..additionally so you dont hear it turning back on (for the insight at least) they send a conterracting sound through the sound system which makes starting the motor have no sound at all!

yea ive driven prius' that i thought i stalled because the electric motor kicks in and the car goes dead silent.
