This is where I Jr drag raced and raced door cars for a lot of years and I've been out a few times and watched this guy race, he lost to an 07 Vette and an 11 sec EVO but still and incredible showcase of electric power. He's powering the back tires. So here's what I wanna know. Is the any possible way to have an Electric battery to run you at RWD and your engine to run you at FWD? Would it be bad for the front wheels to spin under no power? Or could that work? |

Anything can work as long as the idea is tested and then improved over time with trial and error. |

The va tech hybrid vehicle I saw at the state fair was a rav 4, 4wd. They had an electric motor powering the rear wheels and a turbo charged 2 liter suburu engine up front and a controller to merge the two. The postal vehicle on such amps had custom aluminum drums for the rear wheels and a timming like belt driving them. The easiest way is to find an awd metro, if such a thing exist. Now a guy on my insight forum has a hub motor mounted to the bottom of his car and a pnumatic cylinder to lower and raise it from the road. He uses it to get around where not much power is needed or extra regen on braking and uses the spare tire as his air tank. |

I don't believe there was a 4X4 Metro, .......................BUT........................... the Subaru Justy was based on the same platform and there were millions of those sold with 4X4 set up, and the 3cyl 1.0 engine. I once considered using a Justy and Metro and Sprint to make a 4X4, Turbo, 3cyl, Metro. How cool would that be?

Yeah I guess it would be AWD but I was thinking you could run the two at different times. Here's another idea that's on my mind. What if you could harness the power of your spinning wheel or brake disc to create power to charge the RWD batteries? Kind of like the bicycle that powers the microwave or TV.

My point being that I believe the RWD from a Justy would fit in a Metro. Then you could do whatever you wanted with it. |

What about a geo tracker? Yes I know it is a brick. |

I would think that it would take more energy to convert it into electricity than would be effective. Unless you were going to use it as braking, then yes. |

There is no free lunch or net gain. You can use your motor as a generator to capture energy that would be wasted as brake dust to electronics back into the battery, but less than you would get from accelerating. THe best way to beat the system is to make a hybrid that you charge from home, then you recharge by braking only. This will extend your range a lot. Right now most hybrids use the gas engine to recharge the battery as well as braking. Even though this happens, overall the fuel economy is better than just a gas powered car. The tracker is not very aero at all. Sure making it a hybrid would save fuel economy over the original epa. I guess the real question is, do you want to make your own hybrid or awd metro that is gas electric? I doubt an awd metro would perform the same with an electric/gas setup with electric in rear, gas in front. When I visited a performance shop in DE, they had tons of modified cars that were awd. Here in VA and WVA they are just 2wd. |

Oh ok I hear ya schultz, I see what you mean now. Here is another issue I thought of today, what if you were to installs the batteries to work RWD, What about the ignition you'd have to turn the ignition one click to unlock the steering and power brakes. There would have to be some way to make that work, without starting the engine. |

No 4X4 Metros, and the Subaru Justy sold in North America bears no relation to our cars. The Subaru Justy sold in Europe around 98 - 02 was a 4X4 Swift with Subaru badges slapped on it, 100% Suzuki. There were 4X4 Swifts sold in Europe, basically a '94 Metro with the '98 four valve 1.3 engine and a rear differential and axles. Had two gas tanks with a pump that transferred fuel from one side to the other. None of the RWD components will fit on a Metro, the floorpan was different. There were also a very limited number of 4X4 Cultus's sold in Japan, what we call a GTI, but a higher performance version. Had 112 hp instead of the GTI's 100. |

You would need a speed controller. I would tie it tothe throttle cable and try to match it to the original throttle and set it to match the original motor. THat way it would be fairly equal power wiae for your front does. I would then use a switch to kill the injectors when on electric only. Of course you would need to shift to nutral or hold the clutch in while on electric. You can get some pretty cheap lithum batteries from various chineese vendors that are hit or miss in quality and build a pack that is light weight to power it. Just make sure to buy double the cells you need incase half of them are bad. |

Here is a video of my car in action. As you can see its constantly boosting, charging with engine cut and when it cuts the engine it just lifts the cam lob thingie that transfer the motion to open and close the valves. http://www.youtube.com/watch?v=m1iR2P7r0Jg |
