Dragon Dave 1 Posted April 5, 2014 Report Share Posted April 5, 2014 I had an idea and at first my friends said it was crazy but after a bit of a google search, I think this might be possible and not as expensive as I first thought. So I thought I would offer it up here for discussion. The basic idea is to fit electric motors to the back wheels, giving the car 4wd. Each of these motors (Yasa 750 Axial Flux) produces 75kw cont. power (200kw peak power) and 400 nm Torque (800 nm Peak power). The car would still drive the front using the VR6 engine and would have the back powered with the electric motors. The power supply for the motors would come from a rechargeable battery pack and would work in a similar way to an ERS system, charging when braking and using the power to assist in accelerating. When driving at normal road speeds, the car would have double the MPG and if you drive at the track, you could have twice the power! Here is a link to the Yasa motor http://www.yasamotors.com/products/yasa-750/ There is a youtube video of a hybrid kit that is very similar. This kit is designed to operate at speeds of less than 40mph but I don't see why you would have to limit yourself. They say the kit cost $3,000..... seems pretty cheap to me. Here is a link to the video http://www.youtube.com/watch?v=kiQaCJOWTrY this kit is designed for efficiency but I'm thinking of performance. Another company have done a similar thing to a Corvette http://www.greencarreports.com/news/1088309_hybrid-corvette-is-now-real-with-773-horsepower These people specialise in electric motors, inverters, batteries and associated parts for hybrid motorsports http://www.zytekautomotive.co.uk they sell kits like this http://www.zytekautomotive.co.uk/products/electric-engines/motorsport-ers/ weighing a total of just 38.3 kg ..... You would probably need a Formula 1 budget for this kit but your paying for the low weight. This company makes custom packages too! At the moment this technology is going to be very expensive but a few years and I think it will become more affordable! What do you think? Link to post Share on other sites
Daverse 175 Posted April 5, 2014 Report Share Posted April 5, 2014 You would be better (And easier to control) running independent motors in all 4 wheels. And because they run a single solenoid you could do you the speed to could do in forward as you could in reverse.Would make parking fun!Sent from my GT-I9300 using Tapatalk Link to post Share on other sites
