Ford and several third-party companies have offered many modified versions of the highly popular Mustang since its creation in 1964 in order to cater to specific portions of the marketplace outside of the mainstream.
Most variants include both performance upgrades, and unique cosmetic treatments that are typically minimal to maintain the familiar appearance of a stock Mustang.
After debuting at the 1963 Watkins Glen Grand Prix, the Mustang II had a short lifespan as a show car before being relegated to the task of "test mule".
For the first time in the Mustang's nearly 40-year existence, the scoop is a fully integrated design element that creates a triangular opening, and flows forward along the chamfered lower body line.
Notable design changes from the base model included GT-R wheels, Brembo brakes, Pirelli slick tires and a more aggressive look.
"[3] In addition to selling the Mustang in North America, Ford saw the importance of marketing the sporty car overseas as well, especially to American military personnel.
All references to the Mustang name, including the steering wheel hub, side nameplates, the grille, and rear fuel filler, were blanked out, replaced by the words "FORD" only.
For '68, the HCS became a hardtop only and borrowed the front foglights, sidescoops, and Shelby rear end treatments as to not to be confused with the Challenger Special of 1968 that only came with a standard tail housing.
The SCS package also included five new colors: "Vail Blue", "Aspen Red", "Winter Park Turquoise", "Loveland Green" and "Breckenridge Yellow".
The Mach 1 was also equipped with 3.55:1 rear gears, making it capable of very low 13-second 1/4 mile ETs and ~106 mph trap speeds with an experienced drag driver.
Power came from an updated and heavily modified version of Ford's 2.3 L OHC inline four-cylinder engine, featuring a new computer-controlled fuel injection system, and an intercooled turbocharger.
Power output for early units was 175 hp (130 kW), very good for the day, giving the vehicle a stout 0–60 mph (97 km/h) time with the aid of a factory installed Hurst shifter.
The package was offered in Performance Red, Black, Silver, White, and Zinc Yellow, which appeared only on the Spring Feature cars in 2000 and returned in 2001.
The package was available only on GTs and included the following features: Special 17" X 8" bright machined 5-spoke wheels and performance tires 35th Anniversary body-color hood scoop 35th Anniversary body-color side scoops Twin black stickers on each side of hood scoop with color-keyed GT lettering Black "MUSTANG" bumper inserts Production Totals: ( compare years ) Total VIN VCT Body Sub-Total 214,239 P40 Coupe V6 121,026 P42 Coupe GT 32,321 P44 Convertible V6 41,368 P45 Convertible GT 19,224 P45 Spring Feature Mustang 3,091 P47 Coupe Cobra R 300[clarification needed] In 2001, Ford partnered with Warner Bros. to offer a special version of its GT with the Bullitt nameplate, honoring the 1968 390 fastback model driven by Steve McQueen in the 1968 movie Bullitt which became famous for its high speed chase scene.
In addition, a new intake design, high-flow mufflers, and special underdrive pulleys helped increase the power to a conservative 265 hp (198 kW), though many owners report numbers closer to the 270-275 range.
This broader torque curve makes itself known at the drag strip, as these special edition Mustangs could cover the 1/4 mile in 2-3 tenths of a second quicker and about 2 mph (3 km/h) faster than regular GT.
17-inch American Racing Torq-Thrust style rims, wrapped in 245/45ZR performance rubber by Goodyear, were reminiscent of those on the car driven by McQueen in the movie.
Exterior features include uniquely finished 18" Torq-Thrust style wheels and removal of the decklid spoiler and all badges except for the faux gas cap, which is replaced with a Bullitt-specific unit.
The first factory Mustang open-element air filter, unique exhaust that mimics the sound of Steve McQueen's GT 390 Fastback and ends in 3.5-inch tips, and new engine programing raise horsepower to 315 (up from 300).
Performance-wise, the Bullitt came equipped with the Gen 3 Coyote V8 but with the intake manifold, throttle body and airbox from the Shelby GT350 that helped the engine to produce an additional 20-horsepower over the GT at 480.
Beginning in 2007, Ford and ESSENCE have partnered with Susan G. Komen for the Cure to create the Circle of Promise campaign, which aims to increase breast cancer awareness in African-American women.
The entire production is believed to have been done in 35 batches starting March 5, 1984 and ending in April 1984, there was one final Anniversary Mustang Convertible (TBI/CFI Automatic) Produced on June 12, 1984.
As an $895 option available in both Standard and GT editions, coupe or convertible, it consisted of 40th Anniversary badging, enhanced interior with "40th Anniversary" floor mats, painted folding exterior mirrors from the Cobra models, a tan cloth convertible top (instead of canvas), Arizona Beige painted "Bullitt" wheels, and Arizona Beige stripes on the hood, trunk and lower bodysides.
These select Mustangs were converted to street, road racing, and drag cars in Shelby's plant at Los Angeles International Airport.
The Ford 4.6L V8 was upgraded with an Eaton supercharger, a new intake manifold, high performing fuel injectors, an air-to-water intercooler and a lighter flywheel (on the manual transmission only).
Stage 1 options included leather seats, Jack Roush-autographed gauge cluster, and billeted aluminum pedals and shift knob.
A cold-air kit, underdrive pulleys, rear wing, Sidewinder custom side stripes, and some minor computer tuning added slightly over $5,500 to the price of a standard Mustang GT.
In 2000, prior to the introduction of the Q400, the Steeda GT was given the front splitter, which helped keep the newer New Edge Mustangs planted on the ground, and became a popular aftermarket addition.
The 4.6L V8 in the Q400 was modified with a Vortech (or Paxton) centrifugal supercharger, K&N Filter, Ford Racing Performance Parts (FRPP) 70 mm (2.8 in) throttle body, and an HD aluminum radiator.
It comes equipped with a 5.0L Modular V8, producing 500 hp (373 kW) and 530 ft·lbf (719 Nm) of torque, thanks to a Steeda/MagnaCharger supercharger system with an intercooler, a 62 mm (2.4 in) twin-bore throttle body, a Steeda/SCT air meter, 60 lb (27 kg) electronic fuel injectors and a Steeda Intake Kit.
