“A dark horse, which had never been thought of, and which the careless St. James had never even observed on the list, rushed past the grandstand in sweeping triumph.” Beautiful words from the quotable Benjamin Disraeli, and inspiration for the name of the latest Mustang to come from Saleen’s stable. Due to the car’s name it may sound like our title is a clever play on words, but the truth is our seat time was limited to the passenger seat.

We can’t blame Saleen for being careful with the car – the 2009 620-hp Dark Horse Mustang you see here is the first one off the assembly line and is the only one built so far. To their credit, Saleen did take us out to Willow Springs Raceway outside of Los Angeles for some flying laps, so we were able to experience the full capabilities of the car’s performance. Saleen will build only 25 of the Dark Horse Extreme Edition Mustangs, all 25 units will be painted black with a flat black exterior graphics, navigation system, leather steering with alcantara inserts.

“The Dark Horse provides the capability of extreme horsepower and provides the detailed look our customers expect. By merging the Super Shaker with the Extreme powertrain we have created a no compromise solution for people looking for both performance and classic Mustang looks,” states Marc Musial, Chief Powertrain Engineer.

The Dark Horse provides 620HP with 600 ft.-lbs of torque with Speedlab SuperShaker option supplying exclusive styling while enhavncing performance . “The vehicle takes advantage of the ram effect into the SuperShaker air box,” states Dan Agnew, Powertrain Engineering Manager, “It increases pressure in the air box, which adds boost by 0.5 psi and holds air charge temperature relatively constant even with the higher boost.”
