1993 The 1993 Ford Mustang SVT Cobra was launched during the 1992
Chicago Auto Show. It was the premier vehicle of Ford's newly established SVT division, designed to showcase SVT's hallmarks. The exterior of the 1993 SVT Cobra was similar to that year's GT model with differences explained below. The upgrades featured a Ford small block engine#302| "5.0"
V8 engine, rated at a power output of at 4,600 rpm and of torque at 4,000 rpm. According to
Road & Track, the Mustang Cobra could complete a 1/4 mile in 14.5 seconds at a trap speed of . Acceleration from zero to took 5.9 seconds. The drivetrain received an upgraded transmission, rear disc brakes, and for the first time on a factory Mustang, 17-inch unidirectional wheels.
Engine The 1993 SVT Cobra's
short block (cylinder block, crankshaft, rods, and pistons) was carried over from the GT model. SVT engineers added the following performance items: • Cylinder heads — The GT-40 "High Flow" cast iron heads were installed. They were milled for 62.5 cc combustion chambers. The valves measured at the intake, and at the exhaust. The valves are actuated by Cobra-specific 1.7 ratio roller rockers, constructed of aluminum, and produced for Ford by Crane Cams. • Intake manifold — The Cobra upper manifold was unique to the 1993 Cobra and had a diameter round throttle body opening, diverting air into (8) round staggered ports, each in diameter. The lower manifold was identical to the GT-40 manifold used by Ford Racing; it redirects airflow to a rectangular port configuration as needed by the cylinder heads. • Camshaft — The cam is of the hydraulic roller type (same as the GT). However, the Cobra cam has unique specifications of intake/exhaust lift, (209°/209°) duration at , and a lobe separation of 118.3° • Air/Fuel Delivery — The increased airflow and fuel consumption of the Cobra required these upgraded components: Larger (compared to the GT) 24 lb/hr fuel injectors,
MAF meter, throttle body, and matching
EGR plate handle the increased air-intake of the motor. A specially calibrated X3Z
EEC-IV engine control unit runs the system. • Accessories — The crankshaft pulley diameter decreased by 14% (as compared to the GT) in order to under-drive the
alternator (automotive), air-conditioner, and
smog pump, all to increase the power output. The water pump pulley was also decreased in diameter by the same amount in order to preserve the ratio of the pump's speed, and thus coolant flow. These smaller accessory pulleys necessitated a shorter serpentine belt. • Exhaust — To extract the maximum amount of power from the Cobra's powerplant, Ford engineers used tuned mufflers with lower restriction (as compared to the GT). While the factory headers and H-pipe remained the same, the tailpipes were similar to that of a Mustang LX 5.0 L (Sport) model in that they had straight stainless steel tips (instead of turn-down tips on the GT). This is because the Cobra had a revised rear fascia, allowing (unlike the GT) for an exposed dual exhaust.
Drivetrain The Borg-Warner World Class T-5 transmission received an internal upgrade compared to the standard World Class T-5. This consisted of custom gearing for the first to third gears (which were reduced by 10% and hardened) while the fourth and fifth (hardened) gear was the same as standard T-5s found in the LX/GTs. The holding capacity of the Cobra's clutch was increased by way of a higher clamping force pressure plate using the same 10-inch diameter as the GT/LX.
Suspension • The Cobra shocks and struts were sourced from
Tokico and specifically valved for the car by SVT. The springs are linear-rate springs, which were slightly softer than the GT's progressive rate springs. The Cobra also features a smaller front
anti-roll bar, as well as stiffer bushings in the rear upper control arms.
Exterior Styling The Cobra featured a more subdued styling than the GT.
Paint and Interior Trim The 1993 Cobra was available in four exterior paint choices, as shown in the table below. Interior color choices were opal gray cloth, black cloth, and opal gray leather.
1993 SVT Cobra base prices Cobra R The 1993 Cobra R was the first of three special Cobra R models produced. The "R" designation stood for "Race" and as per the name, the cars did not have a radio, speakers, wiring and antenna, air conditioner, foglights, sound deadener, rear seat, rear safety belts, rear carpeting, and roll-up cargo cover, among other items. The car had
power steering, but no other power assist options. It has roll-up windows, manual door locks, and manually-adjustable mirrors. The manually-adjustable Opal Gray cloth bucket seats from the Mustang LX were lighter than the GT/Cobra sport seats, and a piece of thin gray carpeting secured by Velcro covered the bare hatch and rear seat area. The deletions reduced weight by 450 pounds, but this was somewhat offset by the necessary addition of heavy-duty hardware needed for competition. To stiffen the chassis, a strut tower brace was installed to tie the cowl together, and a pair of V-braces (used on all 1983–1993 Mustang convertibles) attached in an X-pattern tied the subframes together. The Cobra R featured Eibach springs that were too stiff for the street, but designed for a racetrack. The Cobra R also had adjustable Koni shocks and struts. The car also featured 13-inch Kelsey-Hayes vented rotors in front and 10.5-inch vented rotors in the back. According to Neil W. Ressler, the executive director of vehicle engineering for Ford Motor Company at the time and one of the founding fathers of SVT, the 1993 Cobra R's brakes
"were the most expensive brakes ever fitted to a [production] ''Mustang. I bought the brakes for the R model out of my engineering budget. I wanted big brakes, and we didn't have them. The program couldn't afford it. Unbeknownst to the higher-ups at Ford, I spent like $2,100 per car to buy those big brakes. But the last thing I wanted was a fast car that didn't stop. We ended up putting good brakes on all those
[Cobra R] vehicles."'' The same 5.0 L V8 from the Cobra was used in the Cobra R. However, the radiator was sourced from what was, by this time, two discontinued Fox-Platform mates: the
Seventh-Generation Lincoln Continental and the
Lincoln Continental Mark VII powered by the
BMW M21 Turbo
Diesel Engine, with a purge tank having been added to this Radiator for improved cooling. A power steering cooler (located behind the left foglight bezel) and an engine oil cooler were standard. The Cobra R wheels were actually the optional 17x8-inch five-lug wheels from the soon-to-be-released 1994 Mustang GT, but were painted gloss black and featured chrome lug covers. The standard tires were Goodyear Gatorbacks. To give the car better front-end geometry, lower control arms from the 1994 Mustang were fitted. Contrary to SVT's stated wishes, many Cobra R models were purchased by private collectors and never actually driven, but several competed successfully in the
International Motor Sports Association (IMSA) Firestone Grand Sport Series and
Sports Car Club of America (SCCA) World Challenge Class B Series. Of the three Cobra R models produced, the 1993 model had the benefit of being the lightest and the smallest. A total of 107 Cobra R models were produced, and all were painted in Vibrant Red Clearcoat. According to Ford's announcement on April 7, 1993, the Cobra R was produced to take the Fox-bodied Mustang out in grand style, a "best of the last" model. According to SVT, the Cobra R can accelerate from zero to in 5.7 seconds and achieve a top speed of .
