The person who took these pictures claimed that they saw a bit of black smoke coming out of the exhaust pipes when the mule tried to speed away from them.
I spotted this prototype Jeep Wrangler. He noticed I was taking pictures and started to drive away very quickly. As he started to pull ahead of me I noticed a bit of “dark” smoke come out of the exhaust. Could this be the 3.0 Ecodiesel Wrangler? They are using LED headlights on this model.
