You would think as long as transmissions have been made for ICE's it would be a no brainer. But with instantaneous maximum torque, no flywheel, no wind up, no buffering or delay whatsoever, just bam, full power -- it turns out to be a serious challenge to make them last. The high power and instant torque of high performance electrics just tears 'em up. Avoiding the added cost, complexity and lowered efficiency they've been as you say, throwing out the transmission, for a single speed reduction gear.

A 150ft-lb torque motor puts out 50% more power at any speed up to 80 if top speed is 80 instead of 120. I'd rather see a 0-60 time of 4 sec in the 0-80 gear shiftable to a 0-120 gear, or just single speed of 0-90. A 2-speed tranny is not a technical challenge! As for the Volt vs Karma, you can't really compare a 400 HP true sports car to a 150 HP sedan, but if economy is much better with the Volt that will further define two totally different markets, like the Accord Hybrid vs Prius. The Accord gave performance with no improved economy and bombed as a product. Dr. Mark Why do these cars both throw out the transmission.
