Dual motors are not new idea, and have brought success in the EV-past. Many years ago when there were few off-the-shelf EV components, Robert Schneeveis built an Electric race car SnoWhite using two 8" ADC Electric motors: http://www.cafeelectric.com/images/Snowhite1.jpg

One of which was a four belted motor EV design mentioned below: http://electric-vehicle-discussion-list.413529.n4.nabble.com/Electric-Salt-Flats-Record-Attempt-tp416927p416929.html Re: Electric Salt Flats Record Attempt Roderick Wilde Sep 04, 2007 I wish Brent all the luck in the world in his attempt! He's a great guy and has done an incredible amount of work towards getting EVs accepted. I was on the "Silent Thunder" team at Bonneville when it did the 132 mph run. I originally built the car and road raced it. After it was purchased by Michael Murphy he had Bob Schneeveis put in the four eight inch ADC motors. It wasn't even breathing hard at 132 mph. The motors were barely warm to the touch after the run. The car just ran out of gearing. - I found a few links for you to explore and ask questions, if you do not get the answers you need: http://www.diyelectriccar.com/forums/showthread.php/dual-motor-differentiali-68527.html The fine-folk at Nedra.com have used dual motors, one example: http://www.nedra.com/100mph_club.html Lowell Simmons June 3, 2011 122.56 mph http://www.nedra.com/photos/100mphclub/black_pearl_800.jpg DC Plasma Lowell Simmons and Black Pearl ET: 11.623 sec. 60 ft: - 1/8: - Event: Test and Tune Track: Palm Beach Raceway Driver: Lowell Simmons Home Town: Miramar, Florida Owner: Miramar High School Class/Voltage Division: HS/A Website http://www.evalbum.com/3547 Specs: Dual 9-inch WarP motors, 300 volts, HTS lithium batteries, Zilla Z2k-HV Nedra has their own discussion group for you to chat with: https://groups.yahoo.com/neo/groups/NEDRA/info Today belting multiple motors together is not as necessary because of inovations/creations like hi-voltage packs powering new motor designs, including the Siamese motor [ https://www.google.com/search?q=Siamese+motor ].
