Continuing the expansion of the ST brand, the all-new Ford Explorer ST is the most powerful and fun-to-drive Ford SUV ever. Engineered by the Ford Performance team, Ford Explorer ST uses a specially tuned 3.0-liter EcoBoost® engine projected to achieve 400 horsepower and 415 lb.-ft. of torque. A top speed target for track drivers stands at 143 mph. Ford Explorer ST delivers an engaging driving experience with a quick-shifting 10-speed automatic transmission and standard four-wheel drive with selectable traction control. Available upgrades include an ST Street Pack and an ST Track Pack. Both have 21-inch aluminum wheels with differing levels of performance brakes and feature larger vented rotors, red-painted brake calipers with stainless steel pistons, and larger brake pads for even better stopping power.
