The 2004 and the 2005 Mustangs bridge the gap between the fourth and the fifth generation of America's favorite pony car. From the New Edge Mustang to the S-197 generation, these two specific model years of the Mustang show some of the most drastic changes in recent Mustang history. While the Mustang core does shine through both models, they look entirely like different vehicles.

2004 and 2005 Mustang Exterior Differences

The 2004 Mustang is the last of the New Edge Mustangs, a subset of the SN95 Mustangs that lasted from 1998 to 2004. Their styling stands out amongst the entire Mustang canon. Compared to other Mustang models, the 2004 Mustang is more sloped and less angular, combining the softer look of the Foxbodies and the early S95 models with a tougher and more intimidating look.

The New Edge exterior is a bit of a misnomer; there aren’t too many hard edges on its outside. The hood of the car bends down towards the smaller grille, flanked by thinner and longer headlights. The quarter panels feature side scoops, a feature shared with previous generations of the Mustang. There is also a small quarter window that is seamlessly connected to the main side window.

The 2005 Mustang, on the other hand, is styled after classic models. The grille, which was hardly existent on the 2004 models, was made considerably larger. This also means that the front fascia of the car is less slanted and flatter, again, bringing the Mustang back to its pony car roots. The headlights are circular instead of rectangular. There are also separate turn signal lights underneath the headlights. The rear quarter window is separated from the main window by the B pillar. Both the 2004 and 2005 Mustang share the pony Mustang logo on the center of the grille.

This iteration of the Mustang is visibly inspired by the Mustang’s roots. One of the words frequently thrown around to describe this generation of Mustangs is retro-futuristic, as it captures the classic pony car style utilizing modern design elements. The 2005 Mustang marks the beginning of the S197 body style which continued until 2015.

2004 and 2005 Mustang Interior Differences

The 2004 Mustang’s interior went mostly unchanged. Besides a few minor tweaks here and there, there aren’t any major additions to the inside. This does mean that the interior of the 2004 Mustang looks a bit retro to some. For the most part, the inside is covered in monochromatic plastic, and the instrument cluster and glove box are situated under large swooping lines that continue the curved theme of the New Edge Mustangs. Being honest, this is one of the most underwhelming Mustang interiors out there. Its reminiscent of mid-nineties economy cars, which considering the otherwise impressive performance of the 2004 Mustang, is disappointing. That said, for every potential problem, there is an aftermarket solution.

2004 Mustang Interior

The interior of the 2005 Mustang is quite handsome, especially in comparison to its predecessor. In some places, aluminum replaces plastic, and the overall simplicity of the interior creates a striking and classy look. The steering wheel was given a complete redesign with the three-spoke design and the tri-bar logo on the wheel's center. In a nod to classic Mustangs, the size of the speedometer and tachometer were significantly increased. Additionally, the color of the backlighting for the instrument cluster can be changed to 125 different colors with Ford's optional MyColor system which was introduced on the Mustang with this model.

Visually speaking, there are quite a lot of differences between these two Mustang models. While the Mustang is known for being a versatile line of cars, these two years represent a dramatic shift in the trajectory of the look of the modern pony car.

2004 and 2005 Mustang Special Trims

The 2004 Mustang has unique trim options as well: The revamp of the Mach 1 and the SVT Cobra. The most notable of these is the SVT Cobra which is also known as The Terminator.

This supercharged Mustang can come with the Mystichrome exterior paint package. It’s hard to miss this dazzling paint color, as it seems to change hue depending on how you look at it. In effect, not only is this vehicle very powerful, it is several colors at once.

The 2004 Mach 1 is also a special Mustang. Each Mach 1 comes with a signature stripe painted down the middle and a functional shaker scoop poking through the hood.

Since the 2005 Mustang had to introduce a whole new generation of Mustangs, there weren't as many special versions of this vehicle. The top trim level for the 2005 Mustang is the GT, which comes with grille embedded foglights, an additional rear stabilizer bar, a leather-wrapped steering wheel, and a rear spoiler.

2004 and 2005 Engine Selection

Both of these Mustang generations have their own pool of engines to draw from. The base level V6 engine in the 2005 Mustang gained a small edge over the base level 2004 engine. Concerning raw power though, the V8 2004 engine from the Mach I is slightly more powerful than the 2005 model, whereas the base V8 from 2004 is less powerful. Between all of their options, they are evenly matched concerning raw automotive power.

Which one of these would win in a race though? The quarter-mile for a 2004 SVT Cobra Mustang is 12.9 seconds at 111 mph, and for a 2005 Mustang GT, the time is 13.5 seconds at 103 mph. Similarly, the 2004 SVT Cobra can make the 0-60 in 4.5 seconds when the 2005 GT can make it in 5.1 seconds. All in all, the 2004 Mustang has a decent edge over the following model. This isn’t purely representative of the stock models of both the 2004 and the 2005 Mustang respectively but rather shows that the performance-oriented models were faster in 2004 than in 2005. Regardless of these figures, there are plenty of aftermarket solutions to raise your Mustang’s speed, irrespective of its year or trim.

Sure, numbers only go but so far. Instead of hearing about how these two Mustangs stack up on the track, why don't you watch it happen?
