It honestly depends and is seemingly random, Tory used to have a b20200 from 2014-15 that still used the huddled winding motor as well as 2013-14 b20200. There are some from 2012 that use the larger capacitor motor so its completely random. Some of the cool colors from 2014-15 still use the huddle winding motor despite me having a 2013-14 cool colors with the 8-pole motor. It appears the only huddled winding motors left in 2013-2015 were the ‘supreme’ motors
