Yes you can drive economically. Renegade Night Eagle (Diesel 2L 140 PS 4x4).
AC off 60 % highway 40% city. Cruising speed 100 kmh (62 mph) on the highway -> 5.3 l / 100km.
The Renegade is the best car I ever had.
Not got the auto, but have 2.0l Diesel 4x4 140 6 speed manual. Just over 7000 miles now & averaging 47.4mpg. My driving is a mixture of short runs, town driving & some long runs on motorways or A roads.Don't believe the hype, UK 2.0 Diesel auto here getting 37 mpg 5000 miles in (I do about 1500 a month)
When I mentioned it to the dealer service manager he laughed & said he'd heard of someone getting 24mpg!
