Aero mode lowers the vehicle to reduce drag and improve fuel economy
The Jeep Grand Cherokee is known for its advanced air suspension system, which enhances its off-road capabilities and on-road manners. The Quadra-Lift Air Suspension system, introduced in the 2011 model, allows the vehicle to adjust its ground clearance according to the driving conditions, improving both efficiency and rugged capabilities.
The Aero mode in the Quadra-Lift system lowers the vehicle by about 0.6 to 0.8 inches (15-21mm) from its Normal Ride Height (NRH) to improve aerodynamics and fuel economy at highway speeds. This reduction in height results in a more streamlined profile, reducing aerodynamic drag and, consequently, improving fuel efficiency. The vehicle automatically enters Aero Mode when it maintains a speed between 62 mph (99 km/h) and 66 mph (106 km/h) for over 20 seconds or if its speed exceeds 66 mph.
The Jeep Grand Cherokee also features an Eco Mode, which is another fuel-saving feature. When activated, Eco Mode optimizes the transmission's shift schedule, lowers the engine RPM, and adjusts the throttle valve diameter to improve fuel efficiency. It also deactivates the Fuel Saver cylinders in V8 models. This mode can improve fuel economy by up to 5%.
In addition to these fuel-saving modes, the Jeep Grand Cherokee offers a Sport Mode, which can also contribute to fuel efficiency. When in Sport Mode, the vehicle is lowered to Aero Ride Height, improving aerodynamics and reducing fuel consumption. This mode also provides a "sportier" feel with reduced body roll.
By utilizing these different modes, the Jeep Grand Cherokee blends performance and comfort, offering a versatile driving experience that adapts to various conditions and priorities, whether it's fuel economy, off-road capability, or a sportier drive.

Sport mode consumes less fuel and produces less gas
The Jeep Grand Cherokee is known for its blend of rugged utility and opulent comfort, largely due to its advanced air suspension system. The Quadra-Lift Air Suspension, introduced in 2011, has been a prominent feature of various Jeep Grand Cherokee models, particularly the Overland and Summit trims.
The Jeep Grand Cherokee comes with four different modes of operation: eco mode on, eco mode off, sports mode, and manual mode. When it comes to fuel efficiency, the eco mode is a standout feature. By pressing the "Eco Mode" button, you can trigger a reduction in the throttle valve diameter, allowing fuel to enter the piston more easily and optimizing fuel efficiency. This mode also adjusts the transmission shift schedule, idle speed, and interactive deceleration fuel shut-off, resulting in improved fuel economy. Additionally, the engine runs at a lower RPM, and the transmission shifts to a higher gear sooner, further enhancing fuel conservation.
While the eco mode is an excellent option for fuel savings, the sports mode in the Jeep Grand Cherokee also contributes to reduced fuel consumption and lower gas production. Sport mode will allow you to have the vehicle in gear with an automatic transmission. This mode is ideal for driving at higher speeds, as it provides a sportier feel and improves aerodynamics. The vehicle will automatically enter Aero Mode when it reaches a certain speed range, typically between 62 mph (99 km/h) and 66 mph (106 km/h), and maintains that speed for over 20 seconds. This Aero Mode enhances fuel economy by lowering the vehicle's height, reducing aerodynamic drag, and improving overall aerodynamics.
The combination of the eco mode and the automatic activation of Aero Mode in sports mode makes the Jeep Grand Cherokee a fuel-efficient and environmentally friendly choice. The specific fuel savings will depend on various factors, including driving conditions, terrain, and overall vehicle maintenance.
