1986-1989 Porsche 911 Cabriolet (G) 3.2 Carrera CAT (218 Hp)

The Porsche 911 Cabriolet (G) 3.2 Carrera CAT, produced between 1986 and 1989, represents a pivotal point in the evolution of the iconic 911. This variant, part of the G-Series (1974-1989) and specifically utilizing the 930.25 engine code, was the final iteration of the original 911 silhouette before a significant redesign. It bridged the gap between the earlier, more raw 911s and the more modern 964 generation. The “CAT” designation refers to the catalytic converter, mandated in many markets during this period to meet increasingly stringent emissions regulations. Positioned as a premium offering within the 911 Cabriolet range, the 3.2 Carrera CAT provided a blend of performance, refinement, and open-air driving enjoyment.

Technical Specifications

Powertrain & Engine Architecture

The heart of the 911 Carrera CAT is the 3.2-liter flat-six engine, designated the 930.25. This engine represented a significant refinement over its predecessors, benefiting from Bosch Motronic fuel injection and improved cylinder heads. The 3.2-liter displacement was achieved through an increased bore and stroke compared to the earlier 3.0-liter engines. The engine’s boxer configuration, with horizontally opposed cylinders, contributes to a low center of gravity, enhancing handling. The Motronic system precisely controls fuel delivery and ignition timing, optimizing performance and emissions. The engine produces 218 horsepower at 5900 rpm and 194.72 lb-ft of torque at 4800 rpm. The standard transmission for this model was a 5-speed manual, although a 4-speed automatic transmission was available as an option, though less common and generally considered to diminish the driving experience.

Driving Characteristics

The 911 Carrera CAT with the 5-speed manual transmission delivers a classic Porsche driving experience. Acceleration to 60 mph takes approximately 6.1 seconds, and the car can reach a top speed of 149 mph. The engine’s torque curve is relatively flat, providing usable power throughout the rev range. The rear-engine layout and relatively short wheelbase contribute to a unique handling characteristic – a tendency towards oversteer, which requires skilled driving. The steering is precise and communicative, providing excellent feedback to the driver. The optional automatic transmission, while offering convenience, noticeably reduces performance and alters the car’s handling balance. Gear ratios in the manual transmission are well-spaced, allowing for spirited driving on both winding roads and open highways.

Equipment & Trim Levels

The 911 Carrera CAT Cabriolet was well-equipped for its time, though options were plentiful. Standard features included leather upholstery, power windows, and a basic sound system. The interior design was functional and driver-focused, with analog gauges providing essential information. Optional extras included a limited-slip differential, sport seats, a more powerful sound system, and air conditioning. The Cabriolet featured a fully automatic, electrically operated soft top, providing open-air driving enjoyment. Interior trim options included various leather colors and wood veneer accents.

Chassis & Braking

The 911 Carrera CAT utilizes a robust chassis with independent suspension at all four wheels. The front suspension employs McPherson struts and wishbones, while the rear suspension features a multi-link setup with trailing arms. This configuration provides a good balance of ride comfort and handling performance. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. The braking system is not equipped with ABS as standard, though it was available as an option. The car’s relatively light weight (approximately 2756 lbs) contributes to its agility and responsiveness.

Market Reception & Comparison

The 911 Carrera CAT was well-received by automotive critics, who praised its performance, handling, and overall refinement. It was seen as a significant improvement over earlier 911 models, offering a more civilized driving experience without sacrificing the car’s iconic character. Compared to the earlier 3.0-liter Carrera, the 3.2-liter engine provided a noticeable increase in power and torque. Compared to the later 964 generation, the G-Series 911 offered a more raw and visceral driving experience. Fuel economy was reasonable for a sports car of this era, averaging around 16 mpg in city driving and 26 mpg on the highway. Reliability was generally good, though maintenance costs could be high due to the car’s complex engineering.

Legacy

The Porsche 911 Carrera CAT (G) 3.2 remains a highly sought-after classic car today. Its combination of performance, style, and historical significance has made it a favorite among collectors and enthusiasts. The 3.2-liter engine is known for its durability and relatively straightforward maintenance. However, like all classic Porsches, regular maintenance and careful attention to detail are essential to keep these cars in top condition. The Cabriolet version, in particular, is prized for its open-air driving experience and timeless design. Values for well-maintained examples have steadily increased in recent years, reflecting the car’s enduring appeal and growing collectibility. The 911 Carrera CAT represents a high point in the evolution of the original 911, and it continues to be celebrated as a true automotive icon.
