2005 Ford Mustang GT: Ultimate Guide

2005 Ford Mustang GT

2005 Ford Mustang GT

The 2005 Mustang GT was all new like the rest of the Mustang range. The Mustang GT came in two options packages: the Deluxe and the Premium. Muscular new engines gave the Mustang stronger performance.

The 4.6-liter all-aluminum V-8 had three-valve heads and was good for 300 horsepower. It had an aluminum block so weight was down 75 pounds  versus the prior cast-iron design. Add 40 more horsepower than the 2004 engine and take away that kind of weight and you saw a big improvement in overall performance and not just in a straight line. 0 to 60 mph for the 2005 GT is over in 5.1 seconds and the quarter mile took 13.7 seconds at 103 mph.

The Mustang GT comes standard with a rear spoiler, but a spoiler delete option is available. 17″ wheels are standard. A TREMEC five-speed manual transmission is standard, but for the first time, a five-speed automatic transmission is available.

Two sets of wheels were available on the GT for 2005. Standard was a revised set of Torq-Thrust replicas that had proved to be so popular on the New Edge generation Mustang. Optional was split spoke bight machine finished alloy that replicated the look of the 2003 Mustang concept car. Both sets of wheels were 17×8-ich alloys that were wrapped with P235/55ZR17 Pirelli all-season performance tires. Tire size on GT’s actually got narrower and half an inch taller. This was done to fill out the large wheel wells of the S197 enhancing the 2005 Mustang’s muscular looks. Chassis engineers also wanted a balanced ride and handling feel and chose the narrower and taller tire to enhance ride comfort.

Behind the new wheels was a new braking system with disc brakes at all four corners. The GT was outfitted with aluminum dual piston floating calipers clamping on a large 12.4-inch ventilated disc that was also 30mm thick. At the rear the GT got single piston calipers and larger 11.8-inch vented rotors. These new front and rear brakes represented the largest set of binders ever installed on a factory mainstream Mustang.

To help give the driver additional control during panic stops GT’s came equipped with a new four-channel anti-lock braking system enhanced with electronic brake force distribution. This system automatically adjusts braking pressure to the wheels that could use it more effectively thus enhancing stability and shortening stopping distances.
