That depends on the vehicle. If it's an ICE with a manual transmission, and you can get it moving fast enough, you can pop the clutch to start it. Back in the day, with a ~dead battery, I'd park on a hill. Even without a hill, 2-3 people can generally just push.
- mwilliaams 7y agoAnd what percentage are manual transmission vehicles these days? Probably less than 1
- nraynaud 7y ago90% of southern Europe?
- rocqua 7y agoWhy just southern Europe? Here in West Europe there is still a vast majority of manual transmission.
- mirimir 7y agoTrue. But some of us still like them. I'm not hard core enough to have a pre-computer vehicle, though.
- macintux 7y agoSome models it’s much higher, but overall definitely single digits in the U.S. Europe has a much higher take rate on manuals.
- dividedbyzero 7y ago>>90% in Germany
- wolrah 7y ago> That depends on the vehicle. If it's an ICE with a manual transmission, and you can get it moving fast enough, you can pop the clutch to start it. This depends on just how dead it is on newer cars. If it's able to run the electronics but just unable to crank enough to start, this can work. If it's dead enough that you can't unlock the doors it's probably also dead enough that the fuel pump, ECU, etc. aren't going to be able to do their thing. Carbureted vehicles can be bump started from flat dead for the most part, but EFI and especially direct injected vehicles need some electricity to operate.
- mirimir 7y agoGood point. I should have noted that I've only done that with a 60s VW Bug. Just to see, I have turned off and restarted my ~10 year old Civic, going down a hill. But not with the battery disconnected. Maybe I'll try it. Not now, though. Edit: And upon reflection, maybe not. Because I'd have to pay someone to reset the computer. Edit: But wait a minute. If the vehicle is moving downhill, and you engage the clutch in first gear, the engine will be turning. And even if it's not firing, the alternator will also be turning. So you should have enough power for the computer, ignition and fuel pump. Or am I missing something?
- drfuchs 7y agoCareful! Shutting off the ignition will lock the steering wheel on older cars.
- ryacko 7y agoThat’s called powered steering.
- mirimir 7y agoIt depends on the vehicle. Power steering can either be electric (EPS) or mechanical, with a compressor that's belt-driven off the engine. My Civic has rack-and-pinion steering with EPS. When the engine is off, it's still steerable, but there's no power assist. But you don't want to turn the ignition lock all the way off, because that does lock the steering wheel.
- jacobush 7y agoDon’t do it with battery disconnected, it can cause the voltage to go too high and you may fry things. Back in the day only bulbs, nowadays who knows.
- mirimir 7y agoThanks. I'm not going to try it.
- userbinator 7y agoInterestingly enough, early automatic transmissions also allowed this, since they had a rear pump that could build up enough hydraulic pressure to power the rest of the transmission without the engine running first: http://oldcarmanualproject.com/manuals/Buick/1953/Owners/images/07_jpg.jpg http://oldcarmanualproject.com/manuals/Buick/1953/Owners/ima... This feature disappeared in the early 60s for cost reasons.
