From Ford press: Ford Expedition combines bold Ford Truck design, functionality and toughness with high levels of interior refinement for consumers who need the flexibility of a full-size SUV. For 2010, Expedition safety and capability both get a boost as Ford’s exclusive AdvanceTrac with RSC is joined by standard Trailer Sway Control.
Trailer Sway Control works in conjunction with AdvanceTrac with RSC to detect trailer sway through the motions of the vehicle and take measures – such as applying precise braking and reducing engine torque – to bring both vehicle and trailer under control.
AdvanceTrac with RSC delivers a level of performance that competitive stability control systems can’t match. Unlike competitors systems, AdvanceTrac with RSC uses a second gyroscopic roll rate sensor to determine the vehicle's body roll angle and roll rate.
If the unique roll rate sensor detects a significant roll angle, the system applies additional countermeasures — such as applying brakes to one or more wheels or reducing engine power — to enhance vehicle rollover resistance. Expedition is powered by Ford’s tough truck-proven 5.4-liter Flex Fuel V-8 engine. Flex Fuel (FFV), a standard feature in 2010, gives consumers more options at the pump. With three valves per cylinder and variable camshaft timing, the 5.4-liter engine delivers a balance of refinement and muscle. Rated at 310 horsepower and 365 ft.-lbs. of torque, Expedition can tow up to 9,200 pounds, for the best tow rating in its class.
With a wider gear ratio, Expedition’s six-speed transmission has smaller steps between gears than a typical four-speed automatic and offers improved shift quality, faster acceleration and improved fuel economy.
