no mazda stops the engine, and then restarts without the starter. they claim 10% fuel savings

My car would start with a 9ms injector prime pulse, that's about all the extra fuel used during starting, so that's what, 1/4 second worth of idle fuel?
as for reliability, that doesn't look like much more than another bunch of code in the ECU, it should be more reliable than starting with the key if you think about it. It looks like a strange bumpstart sequence.

if you stop the engine in the right place, with fuel in the cylinder, firing the spark plug will get it moving enough to run (as those of use with haltechs know!)
i guess the trick was stopping the engine in the right place everytime

Its pretty cool actually, neat idea. You could never do that with the RX8 though, they'd have to call it the iFlood or iPushStart
