I found this video on TFLcar. It compares the Chevy Trax, Nissan Juke, MINI Countryman and Fiat 500X. The video focuses on comparing the 500X to the others, but its still a great comparison to watch.
I'll let you watch the video to get the details of the comparison, but I will lay out the engines and transmissions that each vehicle are using. The 2016 500X has a manual transmission connected to a 1.4L four-cylinder engine with FWD. The Juke has AWD and a CVT. It is using a turbocharged 1.6L four-cylinder engine. The Trax uses a turbocharged 1.4L four-cylinder engine. Finally, the Countryman is using a 1.6L, naturally aspirated four-cylinder.
