The introduction of the “New Edge” Mustang in 1999 also heralded a new era for the SVT Cobra. The 1999-2004 Cobras were notable for their independent rear suspension (IRS), a feature unique within the Cobra lineup. Powering these models was an upgraded 4.6L DOHC engine, boasting 320 horsepower (239 kW) and 317 lb-ft (429 Nm) of torque. However, the initial 1999 Cobra models faced issues in delivering the advertised power, leading to a recall and a temporary halt in production for the 2000 model year. Ford addressed these concerns by revising the intake manifold, exhaust system, and computer components, resulting in an estimated 15 horsepower increase. The 2001 Cobra marked the return of this iconic model, retaining the same power rating but with the earlier performance problems effectively resolved. Despite its smaller displacement and lower compression compared to GM’s LS1 engine found in the Camaro Z28, SS, and Pontiac Trans Am, the 4.6L DOHC Cobra engine held its own in terms of power output.
While the 2001 Cobra shared a significant number of components with its 1999 predecessor, several key changes and refinements were implemented. These updates spanned various aspects of the vehicle, from the engine block to interior and exterior styling cues. Let’s delve into the specific differences that set the 2001 Cobra apart.
Engine Block and Cylinder Heads
One of the most significant changes under the hood of the 2001 Cobra was the engine block. The 1999 model utilized the highly regarded Teksid block, known for its strength and durability. However, for the 2001 Cobra, Ford transitioned to the Windsor Aluminum Plant or WAP block. While the WAP block served its purpose, it is generally considered to be less robust than the Teksid block. Interestingly, some 2001 Cobra models did receive the Teksid block, either as factory installations or as replacement engines, adding a layer of complexity for enthusiasts and collectors. Furthermore, the 2001 Cobra featured newer revision cylinder heads, although specific details on these revisions compared to the 1999 model are not extensively documented, it signifies Ford’s continuous refinement of the engine.

Interior Enhancements: Seats and Trim
Stepping inside the 2001 Cobra, noticeable upgrades in the interior distinguished it from the 1999 model. The seats were specifically designed for the Cobra, featuring a distinctive combination of leather and Alcantara inserts. This suede-like microfiber material added a touch of luxury and enhanced grip for occupants, a step up from the standard Mustang seats found in the 1999 Cobra. Beyond the seats, the center console and trim elements were redesigned, contributing to a more modern and refined cabin aesthetic in the 2001 Cobra. Even the emergency brake received attention, with a leather “boot” added to cover the console opening where it protruded, a small but appreciable detail.

Exterior and Styling Refinements
The exterior of the 2001 Cobra also received subtle yet impactful changes. The rear bumper proudly displayed “COBRA” lettering, replacing the “MUSTANG” designation seen on the 1999 model. Similarly, the rear badge on the trunk lid was simplified to “SVT” instead of the “SVT Cobra” badge of the 1999 version, creating a cleaner look. While both the 1999 and 2001 Cobra models shared the same 17×8 silver powder-coated aluminum wheels, the 2001 Cobra offered an additional option of polished wheels in the same style, providing buyers with more customization. Headlights on the 2001 Cobra transitioned from a chrome background to a black background, often referred to as “smoked” or “tinted” headlights, although the lens itself remained clear and identical to the 1999 model. This darker headlight treatment gave the 2001 Cobra a slightly more aggressive and contemporary appearance.

Transmission and Drivetrain Upgrades
Significant mechanical upgrades were implemented in the drivetrain of the 2001 Cobra. The T-45 transmission used in the 1999 model was replaced with the Tremec 3650 transmission in the 2001 Cobra. The 3650 offered improved strength and shift quality, better suited to the Cobra’s performance capabilities. Furthermore, the IRS half-shafts and differential were upgraded from 28 splines in 1999 to 31 splines in the 2001 Cobra, enhancing the robustness and durability of the rear drivetrain components, especially crucial for handling the Cobra’s power and IRS system. The spoiler was also redesigned, although the specific visual differences are minor and less prominent compared to other changes.
Minor Instrument Cluster and Audio Updates
Rounding out the changes, the 2001 Cobra incorporated subtle updates to the instrument cluster. The color of the odometer digits was slightly altered, and the instrument cluster lighting color also experienced a minor change. While these are very minor cosmetic tweaks, they contribute to the overall evolution of the model. Finally, the CD player was upgraded to a 6-disc unit in the 2001 Cobra, providing enhanced audio entertainment compared to the single-disc unit in the 1999 model.
Conclusion: The Refined 2001 Cobra
In conclusion, the 2001 Cobra represented a significant step forward from the 1999 model. While both shared the core DNA of the “New Edge” SVT Cobra, the 2001 Cobra addressed the initial performance concerns and incorporated a range of improvements and refinements across its engine, interior, exterior, and drivetrain. These changes solidified the 2001 Cobra as a desirable and capable performance car, building upon the legacy of the SVT Cobra lineage.
