Yesterday, I was nearly run over by a car, not an electric car mind you, but if it were I'd be just as dead. I was walking my bike across an intersection of a 3-lane, one-way street. This idjut came barreling about 30+ mph beside 2 lanes of stopped traffic and wizzes past another 100' to the stoplight. I paid heed to a hunch that this was an idjut behind the wheel coming.

You Green Car guys just don't get it! Like any standard automaton, you like your rolling metal isolation chambers to go fast, care little who gets in the way, and clueless about the car infestation. The best future car is the one that need be driven less. Get with it, or get out of the way.

I'm skeptical about in-wheel electric motors. Maybe this Mitsubishi model will put to rest the question of well or how poorly they perform.

Speak for yourself!

Can the genset alone power the vehicle? This would be needed when the battery dies.

The EV discussed by Mitsubishi President Masuko would not have a genset, so if the battery dies you walk.

The Concept-CT hybrid which Mitsubishi showed in Detroit early this year had a 1.0L, 50kW 3 cylinder engine. The ICE is powerful enough to sustain highway speeds up a grade, but by itself would not provide good acceleration. In normal operation the battery would never fully discharge and would thus always be available to provide a boost during acceleration. If the battery truly died (e.g. failed), the car might still be able to operate in "limp-home" mode.

Hi Neil and Rafael,

An alternative to large standard brakes would be small standard brakes and resistors. This is what is used on Diesel/Electric locomotives. The smaller brakes would problably be neccassary if the brakes are wheel mounted along with the motor. The the motor regen current is switched to the resistors, and and a cooling fan for the resistors during braking with full battery. The other brake configuration would be to have brake shafts (no longer drive shafts) to a big central brake at each axle.

The electric-gas hybrid is around the corner. Think about this: The Tesla electric car prototype is only 2500 lbs and has a range of 250 miles. Zero to sixty in less than 5 seconds. The batteries alone are a little over 1000 lbs of the total weight of the car. The electric motor is only 70 lbs and has a steady state power output of 185 KW (248 hp). Now picture this:
Take the same car and instead of 1000 lbs of lithium batteries, use 400 lbs (181 Kg) of the A123 Systems lithium-ion batteries. At 4 hp per Kg, there is more than enough juice to feed the electric motor at max power (727 hp max). Saving 600 lbs in batteries will put this car at only 1900 lbs. Add a high efficiency, low power (40 Hp) diesel engine or high compression Atkins engine with a 50 Hp electric generator and the total weight should still be below 2200 lbs. This will give you a range of well over 100 miles in electric mode and 40 hp of electricity would propel this light, aerodynamic car well over 70 miles per hour in any highway

I am so sick of all the clowns talking about the Tesla as if it were not a chalatans's trick. They didn't repeal the Law of Conservation of Energy or the Laws of Thermodynamics. What the Tesla people claim is flatly phoney! And there is nothng but one or two crude prototypes to back the Tesla claims.

Does the prototype go fast? Yes. So what? I don't believe the other claims. They haven't done anything that a thousand others haven't done; and their results are completly different.

Got some calcs that will prove your point?

And if they come out next year and work will you admit you're the Gull of BULL?

I have reservations about wheel motors. Designers of high performance cars, motorcycles, and mountain bikes spend a lot of effort and money to minimize unsprung weight. Putting the motors in the wheels is the exact opposite of what a race car builder would do. How are these things going to ride and handle? Also, the wheel is a horrendous environment for a motor. What happens when you drive through a deep puddle?

Look for all-electric running gear--Bose adaptive electromagnetic suspension, light weight, efficient in-wheel motors, electric brakes. If you don't like the unsprung weight, put the motor and brake disc inboard, with u-jointed half-shafts to the wheels.

Electricity is cheaper and cleaner than gasoline.

Bicycles are good! Velomobiles are good! Electric cars are good! Regardless of human or electric power, weight and drag reduction are the key. It is time to stop hauling 5,000 lb. of steel to get 1 quart of milk.

I think we will see a clean, green future, if we live long enough. Taking money away from people who build gas guzzlers won't be easy.

I am encouraged that $3.00 gasoline may have broken the floodgate that held back the future.

Ni-Mh battery pack of Prius (which is a miracle of performance and durability), makes use only of 1/3 of its claimed energy capacity – to assure long life and safety of battery operation. Whatever numbers you hear from battery producers – divide specific power in half, specific energy in three, travel on one charge in five, and multiply fast charge time by ten. This rule of thumb is established in 40+ years of EV commercials.

I like that one company using lithium energy batteries and ultracaps. If they can make the batteries last longer doing this, it could change things.

The key is the battery!
We know Ni-cad (like in the Prius) uses barely a fraction of the batteries capacity so as to extend battery life. And we know Li-ion is dangerous in a laptop, so how are 1000 3v cells going to work in a car!
Li-ion is inherently unsafe - now put it in a car crash and you have a recpie for disaster.
I don't know why car companies don't do a deal with Valence technology. Not to plug them too much but they have a battery that's better than Li-ion battery that's safe under ALL "stress" conditions! and a life of >2000 charges too 90% charge capacity (compared to <600 for li-ion) If a car company could get onboard with 10000 units+ then they'd get the cost down too.

I drive a plug-in electric that provides a battery with a motor built into each wheel. It has 20 mile roundtrip capacity at 5-8 mph which is completely adequate for a wheelchair. Soft tires suffice in lieu of shocks & springs. For basic transportation we can't expect or want every thing.
For Mitsubishi I say: "Keep it Simple S,,,," Do not confuse car concepts with essential transport. If we want a car, we can either buy or rent one when needed.

- i need to buy a control unit for mivec 1.6 4g92 16.v how much it will cost

- i need to know it the control unit of the mivec fto 2.0 can work on the 4g92 engin and if it works it will give me more power and how much illl gain hp and how much the price

- i want to let my car so fast and high acceleration over 250 tourq tell me what can i do
