Transformance Characteristics
The nine-speed automatic transmission in the 2.4-liter Renegade has been criticized by some reviewers for hesitant shifting behavior, which can impact fuel economy. The transmission's programming sometimes struggles to find the optimal gear, particularly in hilly terrain or during passing maneuvers, leading to unnecessary engine revving and increased fuel consumption.
Aerodynamic Considerations
The Renegade's boxy, upright design—while contributing to its distinctive appearance and spacious interior—creates more aerodynamic drag than the sleeker profiles of competitors like the Hyundai Kona or Mazda CX-3. This design choice negatively impacts highway fuel economy, particularly at speeds above 60 mph.
Terrain and Driving Conditions
Like all vehicles, the Renegade's fuel economy suffers in stop-and-go city driving, extreme temperatures, and hilly terrain. However, its off-road orientation means some owners may drive in conditions that particularly penalize fuel efficiency, such as sand, mud, or rocky trails where four-wheel drive is engaged and momentum is inconsistent.
Ownership Cost Projections: Beyond the Pump
While fuel costs represent a significant portion of ownership expenses, a comprehensive understanding of the Renegade's economics requires considering additional factors.
Annual Fuel Costs
Based on 15,000 miles of annual driving (55% city, 45% highway) and the 2018 national average gas price of $2.60 per gallon, a front-wheel-drive Renegade would cost approximately $1,560 annually in fuel. The four-wheel-drive version would cost about $1,625 annually—a $65 difference.
