The Porsche 911 Targa (G) 2.7, produced between 1973 and 1975, represents a pivotal moment in the evolution of the iconic 911. Falling within the G-Series (1974-1977) of the 911, this variant was characterized by its distinctive Targa top – a semi-convertible design featuring a removable roof panel and a fixed roll bar. The 2.7-liter engine, introduced in 1973, was a significant upgrade over previous models, offering increased displacement and power. This particular 150 hp configuration, paired with a 5-speed manual transmission, positioned itself as a desirable entry point into the 911 range, balancing performance with relative affordability. It served as a bridge between the earlier, smaller-displacement 911s and the more powerful, later iterations.

Powertrain & Engine Architecture
The heart of the 911 Targa 2.7 was the Type 911/92 flat-six engine. This 2.7-liter unit represented a significant leap forward from the earlier 2.4-liter engines, offering increased displacement and a more robust design. The engine utilized a Bosch mechanical fuel injection system, a hallmark of Porsche engineering at the time, providing precise fuel delivery for optimal performance and efficiency. The single overhead camshaft (SOHC) design, while relatively simple, proved reliable and contributed to the engine’s characteristic smooth power delivery. The engine’s boxer configuration – with cylinders opposed horizontally – lowered the center of gravity, enhancing handling and stability. The 5-speed manual transmission, a standard feature, provided precise gear changes and allowed drivers to fully exploit the engine’s power band.
Driving Characteristics
The 150 hp 2.7-liter Targa offered a compelling driving experience. While not the fastest 911 variant, it provided ample power for spirited driving on both winding roads and open highways. The rear-wheel-drive configuration and the relatively lightweight construction contributed to a balanced and responsive feel. The 5-speed manual transmission allowed for precise control over the engine’s power, and the gear ratios were well-suited to both everyday driving and more enthusiastic pursuits. Compared to the more powerful 911 Carrera RS, the 2.7 Targa offered a more accessible and forgiving driving experience, making it a popular choice for drivers who prioritized usability and comfort alongside performance. Compared to the later 911 SC models, the 2.7 felt less refined but possessed a raw, engaging character that many enthusiasts appreciate.
Equipment & Trim Levels
The 911 Targa 2.7 was generally well-equipped for its time, though options were plentiful. Standard features included comfortable seating for four, a leather-wrapped steering wheel, and a comprehensive instrument cluster. The Targa top, of course, was the defining feature, offering an open-air driving experience while maintaining a degree of structural rigidity. Interior upholstery typically consisted of cloth or leatherette, with leather being an optional upgrade. Optional extras included power windows, a sunroof, and upgraded audio systems. The trim level was relatively consistent across the 2.7 Targa models, with variations primarily stemming from individual owner specifications.
Chassis & Braking
The 911 Targa 2.7 utilized a robust chassis featuring independent suspension on all four wheels. The front suspension employed a combination of spring struts and wishbones, while the rear suspension utilized a trailing arm design. This setup provided a good balance of ride comfort and handling precision. Disc brakes were fitted to all four wheels, providing ample stopping power. The braking system was unassisted, requiring a firm pedal effort, but offered consistent performance. Stabilizer bars were included at both the front and rear, further enhancing handling stability. The relatively light curb weight of around 2359 lbs contributed to the car’s nimble handling characteristics.
Market Reception & Comparison
The 911 Targa 2.7 was well-received by automotive critics and enthusiasts alike. It was praised for its improved performance, refined handling, and distinctive Targa top. Compared to the earlier 911 models, the 2.7 offered a more sophisticated and enjoyable driving experience. Fuel economy was reasonable for a sports car of its era, and reliability was generally good, although maintenance costs could be significant due to the car’s complex engineering. Compared to other sports cars of the time, such as the Jaguar E-Type or the Chevrolet Corvette, the 911 Targa 2.7 offered a unique blend of performance, practicality, and style.
Legacy
The Porsche 911 Targa 2.7 remains a highly sought-after classic car today. Its combination of iconic styling, engaging driving dynamics, and relative reliability has ensured its enduring appeal. The 2.7-liter engine is considered a robust and durable unit, although regular maintenance is essential to keep it in top condition. Values for well-maintained examples have steadily increased in recent years, reflecting the car’s growing desirability among collectors and enthusiasts. The 911 Targa 2.7 represents a significant chapter in the Porsche 911’s storied history, and it continues to be celebrated as a true automotive icon.
