hhmmm

ok coupers, thinking caps on:

what do you think the systems weighs?
After looking at the 2002 conversion on the web site, those are some big batteries at I'm guessing 75-125lbs apiece....so if the systems basically weighs the same as the M30 set-up, (engine +fuel tank etc), costs 15-20k (my guess) to convert car to 800hp! and never going back to the pump ($60-$80 a tank depending on where and what kind of juice you prefer etc)....

... would you consider it? (power would be fun, but I would miss the m30 sound, smell & charm)

ok, back to work everyone
;-)
 
I don't think this car is meant to be practical or a daily driver. The goal is to make the fastest electric car.

I was thinking a flux capacitor conversion would be good, but maybe this could be an interim solution.

I was thinking more of an oscillation overthruster:

Has anyone asked what sort of stiffening an e9 chassis would require to handle 800hp?

The 1/2 hour video segment is very informative. Certainly a cottage industry to keep an eye on. Nice mix of shapes being converted to EVs.

I'll take the P-car 904

ok .....really getting back to work now

;-)
 
Mike Pethel is just no ordinary geek trying to save the world with his electric car. He is a true car guy and a total BMW enthusiast. He told me he wants to pump a 1000hp out this coupe. Great guy, great story. He says he loves to go up next to a Ferrari or Porsche and just blow their doors off....all with a car that makes no noise...LOL!

It's not the horsepower that twists the chassis, it's the torque. An electric motor has a very different torque curve than an ICE. Some dyno charts for an electric Porsche, note that torque is basically maxed out at 0 rpm.

Sure. Horsepower is the product of torque and rpm. The chassis has no idea of what rpm the engine/motor is turning - it just "feels" the torque. So whether peak torque is pumped out at 0 rpm or 6,500 rpm doesn't change the forces applied to the chassis by that torque.

So to re-phrase my comment, I'm still curious how a humble 9 chassis handles the torque required to smoke the tires as shown on the video.
 
I'd forgotten about the oscillation overthruster...

There's something very appealing about the builder's aims on this one, -as shown in that link. Sort of more mad scientist-hobbyist than hot rodder. Nice to see a coupe utilized as the platform too in a non-precious way.

I'd be curious to see more detail on torque and strengthening issues like others, but makes you wonder about simple, viable power in the 3-400HP range with some lighter batteries in a few years. Especially if they were arranged in a balanced way under hood and in trunk rather than in the cabin. And at some point, someone is going to provide appropriate digital sound effects for retro-fit use if only to avoid running over pedestrians with their quiet supercar.

Clearly not period correct, but cool in a gee-whiz! sense.
 
A little bird told me to watch out for a photoshoot and Car of The Month feature very soon.

Believe it or not it's a slightly tamer version of what it once was.
 
I love the quote that he bought the coupe as to have a car "I can work on for the rest of my life" Kinda' say's it all in my book. We all love fiddling with drivetrains and modifications to our own liking....at the end of the day it is the shape and iconic style of the vehicle as well as exclusivity. This guy is a brother and cult member for sure. Can't believe the half shafts don't blow apart....
 
I am always a little amused that electric cars are "green". They always forget to mention that the power plant that feeds their battery charger pollutes quite a bit.
 
economies of scale

Well, the key concept here is economies of scale: 1 big power plant that feeds n electric cars is more efficient and pollutes less than n gas engines.
 
Often overlooked is the fuel used and resulting pollution along with the toxic effect on the environment of mining and smelting the nickel etc for the batteries which are eventually disposed. I submit that the net effect after all considered is more favorable to the environment with an efficient gas powered prius-sized car than the actual prius polluting someone else's back yard. But this reality doesn't fit the green template.

OK. Let me switch to fuel operated laptops, cellphones, and lights in my home...

I think that spreading the impact away from the place of consumption is good even if the net is the same.

Now, hybrids that just increase gas mileage are terrible, and this smart contrarian explains why:
