Lightbulb Bill Caswell Takes 420 HP BMW M3 Electric Pikes Peak Race Car for Test Drive

Quote:
Rally racing's favorite privateer and Pikes Peak veteren, Bill Caswell [of the controversial "Death of BMW's M Brand" Jalopnik article] stopped by the EV West shop to take the electric M3 for a test ride. Ride along with Bill as he takes his first ride in a performance oriented electric vehicle.
EV West took a 1995 BMW M3 and replaced its 6 cylinder 240hp S50 engine with a NetGain DC electric motor and Evnetics Soliton Shiva motor controller, packing 420 totally green horsepowers! [Original Thread and Video]

I believe something to do with electric motors themselves doesn't require them to have as many, but they usually do. The Tesla Roadster, for example, has two gears.

They changed the gearbox to an single-speed gearbox

on wiki you can find:

Quote:
The company previously worked with several companies, including XTrac and Magna International, to find the right automatic transmission, but a two-gear solution proved to be too challenging. This led to substantial delays in production. At the "Town Hall Meeting" with owners in December 2007, Tesla announced plans to ship the initial 2008 Roadsters with their interim Magna two-speed direct shift manual transmissions locked into second gear, limiting the performance of the car to less than what was originally stated (0 to 60 mph (0 to 97 km/h) in 5.7 seconds instead of the announced 4.0 seconds). Tesla also announced it would upgrade those transmissions under warranty when the final transmission became available.[50][52][91] At the "Town Hall Meeting" with owners on January 30, 2008, Tesla Motors described the planned transmission upgrade as a single-speed gearbox with a drive ratio of 8.27:1 combined with improved electronics and motor cooling that retain the acceleration from 0 to 60 mph (0 to 97 km/h) in under 4 seconds and an improved motor limit of 14,000 rpm to retain the 125 mph (201 km/h) top speed.[92] The upgraded system also improved the maximum torque from 200 to 280 ftlbf (270 to 380 Nm) and improves the Roadster's quarter mile times.

Well none from the car itself but plenty from charging it. Unless of course you charge with 100% renewables. Even then technically you need to factor in the emissions from the manufacturing of the renewable device...

Hmm. Then I'm not too sure. Maybe its cost prohibitive to develop something like that?

So awesome!

Regarding gearboxes, etc. Electric motors present a different set of challenges than IC engines.

An electric motor has a very flat torque curve. They generate torque from a standstill all the way to 15k RPM (varies). Ask any gearbox mechanic, and they'll tell you that torque is what breaks gearboxes.

Building a gearbox that can hold up under the stress of such a flat torque curve isn't easy. A gear set needs to be strong to hold up under the torque load, but needs to dissipate heat readily when operating at high RPM. The two engineering needs are in conflict. A bulky gear set is strong, but retains a lot of heat. A lightweight gear set dissipates heat readily, but can't hold up under the torque. I expect we'll see some innovation in gearbox engineering as EV picks up steam in the enthusiast market. Active cooling, exotic materials... you name it, it's coming.

One thing is for sure. There is no reason to think that the trend toward EV means a decline in fun for the enthusiast. To the contrary, I think EVs have the potential to be just as exciting as an IC engine, if not more.
