The Porsche 944 Cabrio 3.0 S2 CAT, produced from 1989 to 1991, represented the pinnacle of the 944 Cabriolet line. It was the final iteration of the popular 944 series, offering increased performance and refinement over earlier models. Positioned as the premium open-top variant, the 3.0 S2 CAT benefited from the larger 3.0-liter engine previously found in the 944 S2 coupe, combined with catalytic converters to meet increasingly stringent emissions regulations, particularly in the North American market. The 944 series as a whole was Porsche’s attempt to create a more affordable, front-engined sports car to broaden its appeal beyond the iconic 911, and the Cabriolet version further expanded that reach by offering open-air driving enjoyment.

Powertrain & Engine Architecture
The heart of the 944 Cabrio 3.0 S2 CAT is the M44.41 engine, a 2.99-liter inline-four cylinder powerplant. This engine represented a significant upgrade from the earlier 2.5-liter versions, featuring a larger bore and stroke. It utilized a Bosch Motronic fuel injection system, managing fuel delivery and ignition timing for optimal performance and efficiency. The engine employed a single overhead camshaft operating four valves per cylinder, contributing to its relatively high specific output. The “CAT” designation indicates the inclusion of a catalytic converter, a crucial component for meeting emissions standards. The 5-speed manual transmission was the standard offering, providing precise gear changes and a direct connection to the engine’s power. The engine’s longitudinal mounting and rear-wheel drive configuration were hallmarks of Porsche’s engineering philosophy, prioritizing handling balance and driving dynamics.
Driving Characteristics
The 3.0 S2 CAT offered a noticeable improvement in performance over earlier 944 Cabriolet models. The increased displacement and refined engine management system resulted in a more responsive and powerful driving experience. Acceleration to 60 mph was achieved in approximately 6.7 seconds, and the car could reach a top speed of 149 mph. The 5-speed manual transmission allowed drivers to fully exploit the engine’s powerband, while the rear-wheel drive layout provided excellent handling characteristics. Compared to the 2.5-liter models, the 3.0 S2 felt significantly more capable, particularly during highway passing maneuvers and spirited driving. While not as raw or visceral as the 911, the 944 Cabrio 3.0 S2 offered a refined and engaging driving experience that appealed to a broader audience.
Equipment & Trim Levels
The 944 Cabrio 3.0 S2 CAT came standard with a relatively well-equipped interior. Leather upholstery was standard, along with power windows, central locking, and a basic sound system. Optional extras included a more sophisticated stereo system, heated seats, and a limited-slip differential. The dashboard layout was functional and driver-focused, with clearly marked gauges and intuitive controls. The Cabriolet top was manually operated, although an optional power top was available. The interior trim was generally understated and elegant, reflecting Porsche’s commitment to quality and refinement.
Chassis & Braking
The 944 Cabriolet utilized a torsion beam rear suspension, a cost-effective solution that provided a good balance of comfort and handling. The front suspension featured MacPherson struts with anti-roll bars. Braking duties were handled by ventilated disc brakes at the front and solid disc brakes at the rear. The braking system was generally effective, providing ample stopping power for everyday driving and spirited performance. The chassis was reinforced to compensate for the lack of a fixed roof, ensuring structural rigidity and minimizing body flex.
Market Reception & Comparison
The 944 Cabrio 3.0 S2 CAT was generally well-received by automotive critics. It was praised for its improved performance, refined handling, and comfortable interior. However, some critics noted that the Cabriolet version suffered from a slight loss of structural rigidity compared to the coupe. Compared to the 944 S2 coupe, the Cabriolet offered a more open-air driving experience but at a slight compromise in handling precision. Compared to the base 944 models, the 3.0 S2 CAT represented a significant upgrade in performance and refinement, justifying its higher price tag. Fuel economy was reasonable for a sports car of its era, averaging around 19 mpg in combined driving.
Legacy
The Porsche 944 Cabrio 3.0 S2 CAT remains a popular choice among enthusiasts today. The M44.41 engine is known for its durability and relatively straightforward maintenance. However, like all older Porsches, regular maintenance is essential to keep these cars running reliably. The Cabriolet version is particularly sought after for its open-air driving experience. While prices have been steadily increasing in recent years, the 944 Cabrio 3.0 S2 CAT remains a relatively affordable entry point into Porsche ownership, offering a unique blend of performance, style, and driving enjoyment. Its impact lies in broadening Porsche’s appeal and demonstrating that a front-engined sports car could deliver a truly engaging driving experience.
