Would this work for a hybrid vehicle?

protokatie:
Is it just me, or does it strike others odd that my 1994 Geo Metro gets the same gas mileage as these new fangled hybrids? Too bad I got rid of the Metro... Miss that car, and its suprisingly powerful 3 cylender engine... They should bring it back!

Ummon:
Does it strike one as odd that Tucker got 28mpg in 1950 from a full ton car?  When I was in high school, I used to try to think up crazy ways one could...at least sorta....but not really of course....design a veritech fighter. Some things are silly. Some things are happening and you can just sit back. And some things haven't happened because somebody didn't want them to. Where are you in this? This topic now officially belongs in PnR.

That did strike me as odd, so I just did a little searching and found your numbers are a bit off.  The Tucker was able to get 24mpg under perfect conditions, but the factory tests showed it only got 20mpg at 50-55mpg.  That still is very impressive milage for the size and age of the car, but not all that unusual.

Has toyota made the prius available as a plug-in yet?  I thought someone had kits to do so...

you have got to be joking. I had a big old Renault and it weighed about 800kg. It's counterparts today really do weigh 1600kg. My tiny Honda already weighs 1200kg.

i guess it depends what you consider 'big'. my type 3 vw is 880kg. heavier than your 'big' renault. but i wouldnt consider a type 3 to be big. if we only talk about small cars then surprisingly, you arent far off the mark. i searched for a vw golf as an example. looks like the first models weighed between 800 and 900 kg. the latest weighs 1447kg. but we tend to still think of larger cars as normal in australia. i looked for ford falcon as an example since they are a popular australian family sedan. the first model, the XP, from the 60's (which looks friggen awesome in the 2 door model  8)) weighed 1170kg, while the latest model weighs about 1700kg. which is obviously not double. regardless, i still dont see the significance of that. you design the system around what the car weighs...

Well that's what I meant. You said they should use a 40hp petrol engine. That's not going to be enough to move a 1200 to 1700kg car.

well, it WAS a ballpark estimate. im quite pleased with my guesses so far, although i was surprised by the low power of the prius engine. 40hp WILL move a 1700kg car however, depends on how fast and how quickly you want to go. you'll be able to do over 100km/h in it. i think in the future we'll learn that we don't need to accelerate like a top fuel dragster to get to work or go shopping...
