I read on their facebook page it currently weighs somewhere in the low-mid 2000 lbs. They stated their limit is to not go above 3,000lbs when it's completed.


Weight distribution was around 46/54 (front/back) if I remember correctly.

Here are a couple good quotes from the EV West Facebook page:

"the need to blow tons of air through a racing engine is indeed a serious thing. 265v x 3,000 peak amps is 795,000watts. At 90% efficiency that's an 80killowatt heater that really can't be allowed to get hot. Mind you, that amount of current will be quite intermittent, but there is still alot of unwanted heat possible." - Nabil Ahmad Sean

"Nabil, thanks for the great answer as to why there are blowers on the motor. And to Zack, the final weight right now is 3400 without any carbon doors, hood, etc. The distribution is currently 54 rear, 46 front. In it's current configuration the car has 525 hp, but we're planning a mid-engine version that should top 1000 hp." - EV West


Long range doesn't appear to be the main concern for this Pikes Peak race oriented M3. EV West does have a 100 mile range Ford Ranger on their website. Most EV's I have seen do 40-100 Mile range on average. Great for most daily driving and around town stuff. Long range is still combustible engine territory. EV technology is still quite expensive and has quite a ways to go.



Here is the transmission with the two electric motors:

Hey guys,

Just created an account here to answer any questions about the car. We appreciate the kind remarks, and really dig how the BMW community has treated this project. I'll try to keep checking back throughout the day.

A couple of quick unanswered questions... The range is about 140 miles if you're just driving it like a normal street car. Under race conditions, our preliminary testing indicates we'll get about 40 miles. Pikes Peak is uphill so it will be less than that.

The transmission is a 2 speed Powerglide, like those used in drag racing and circle track. We use an external electric pump to keep pressure in the trans when the motor isn't running so it stays engaged at a dead stop.

The weight is about 400 pounds more than a stock M3, but with a continuous stream of battery improvements, this should fall well below stock M3 weight soon.

We will be racing the car in the Electric Class at Pikes Peak on Aug 12th, against the likes of Monster Tajima (in an electric car) and factory efforts from Mitsubishi and Toyota, so we're sort of the DIY garage under dog effort.
