OK. I admit it... I dig green technology. Well I dig all technology, but I digress...
I'm curious how emissions vs. gas mileage balance out. For example: My '88 FJ62 gets about 12 MPG on a good day, but has F.I., Catalytic Converters, and all that good stuff. My 914 gets over 2X that, but has no emissions equipment at all. I'm curious at where the tipping point is: 2 stroke scooter vs. compact car 4 stroke scooter vs. compact car etc... I'm even considering trying to build a junkyard/STF electric motorcycle. I'm poor, but have plenty of time and creativity! Comments? -Aaron |

Carbon In = Carbon Out so better fuel economy = less carbon released to the atmosphere. Your 914 wins the carbon contest.
3-way catalysts have pretty much set all cars up to be pretty clean as far as all the other stuff is concerned. Your 914 loses the "other pollutant" contest by a lot. FWIW , 4-stroke is better than 2-stroke by a long shot ...especially when no catalyst is involved. All bets are off if you have an old Saab 95 (me loves the 3 cylinder 2 Stroke): you're single-handedly killing the planet with that! |
