309,9 Kgm of tourque, 0-100 km/h (62mph) in just 4,5 seconds, 240 Km/h top speed and 1.500 Km autonomy
Sounds perfect don’t you agree? PML’s Mini concept was unveiled at the British Motor Show this week and it features 4 electric powered motors (one for each wheel) that generate a stunning 640 Hp (160 Hp each). More astonishing is the torque that sums up to a total of…3.000 NM or 308,9 Kgm !!!
According to PML, the all wheel drive electric powered mini needs a mere 4,5 sec (!) to accelerate from standstill to 100 km/h (62mp/h) while it’s top speed reaches 240 km/h (149 mph). PML say’s that athough a production model would be a bit slower (0-100 km/h in 6 seconds) the impressive 1.500 km (932 miles) autonomy will be retained.
Another real cool thing is the fact that the car wears a 250 cc 2 stroke petrol engine attached with a generator that supplies power to the batteries. As the battery level reduces, the rear mounted engine/generator starts to automatically top up the battery. So when you arrive at your destination you simply park the vehicle knowing that when you return the battery will be replenished!
Although the project wasn’t supported by BMW (BMW UK Ltd requested that PML mention that they have no involvement with the project and that such conversions invalidate warranty) PLM hope that a car maker will be interested in the technology.
I on the other hand hope PML can keep it’s promise concerning their systems hugely impressive specifications.

Traction control: Dynamically distributes torque when any wheel is in skid management mode to obtain optimum tractive effort and stability.
Steering sensor: Optional addition to provide feed forward input to traction control system. Allows driver intent and wheel alignment to influence vehicle stability and tractive effort functions.
Vehicle attitude, yaw and gyroscopic sensors: Optional addition to provide further stability inputs to traction control system. Allows vehicle orientation and direction (if different from steering wheel implied direction) to be accounted for in determining optimum tractive effort distribution.
Differential/torque share functions: Standard feature incorporated within each wheel to allow optimum speed and torque share when cornering. Minimises tyre scrub and power wasted energy.
Efficiency optimisation: Dynamic management of power delivery to wheel ensures best use of available power. Accounts for motor related efficiency variations across speed and torque ranges.

I wonder how much it cost in production form?
all i see is a picture of a mini... lets see proof!!! post a video clip!!
Want more about the braking system. Seems some sort of mechanics would be necessary to stop the car while traveling at 150 mph.
what's the curb weight ?
If the big companies are not interested on this project. How much $$ do you need to raise to start a limited project? maybe an excentric millionaire is reading this blog also...
It's ok... but this is much much cooler http://www.teslamotors.com

never use imageshack.us it sucks, use photobucket.com
yeah, use photobucket.comm, please repost the pics, im very interested to see them
I've heard of a braking system on coaches and buses that uses electromagnetism to (quite efficiently) act as a non-mechanical brake... although I'd be interested to see how it copes when parked on a hill
i hate yellow frogs.
frogs?
Yeah but who cares it is a Mini, dont get me wrong if your gay or your a soccer mom, or a gay soccer mom it is the car to have well that or an H2, lol...
20kW from the generator attached to a 15kW engine ?!?
Yeah, right.
http://www.dansdata.com/danletters171.htm
gives a writeup of all the problems with that design.
its just a bad idea.
I think dan should take a look at the company website instead of reading some 3rd party site and taking it as absolute truth, he also seems to do some word play or at least he doesnt read the article correctly.
To me there does seem to be something wrong with the 640hp and 0-60 in 4.5 seconds issue.
Seems like the car must be really heavy, or it's not actually getting 640 hp to the wheels.
The 20kw rating on the generator is not what is generates, but what it's capable of generating if you input 20kw of mechanical power.
My guess is that the 4 160hp electric motors on the wheels can generate 160hp each if you input 160hp of electric power to each wheel. However it's my belief that the whole system is not able to input that amount of power for an entire 4.5 seconds, and therefor the lack of expected acceleration.
My buddy Austin loves this Mini. He is a bit large for it... but sucks a mean schlong. So, do you think it would be a good car for him still?

How far can this car travel on one charge
Proves technology exists right now to go electric and reduce oil demand for auto propulsion.
