The 1966 Porsche 911 Targa marked a revolutionary moment in automotive history, introducing a fresh take on open-air driving that combined the structural integrity of a coupe with the exhilaration of a convertible. Launched late in 1966, this model debuted the distinctive Targa roof system, featuring a removable panel and a prominent roll bar, setting it apart from traditional roadsters of the era.
Birth of the Targa Concept
Porsche faced challenges in the mid-1960s with evolving safety regulations that threatened the viability of fully open convertibles. The company responded with the Targa variant of its new 911 lineup, first rolling out in December 1966 for spring 1967 deliveries. This design utilized a sturdy steel roll hoop in place of conventional B-pillars, enhancing chassis rigidity while allowing the front roof section to be stowed and the rear plastic window zipped out for full exposure to the elements.
The Targa’s aesthetic captured the swinging ’60s vibe, resembling a modernistic drop-top with practical engineering. It provided implied rollover protection without formal crash-test guarantees, proving popular enough to sustain as a niche model through subsequent decades.
Engineering and Design Highlights
At its core, the 1966 911 Targa featured a rear-mounted, air-cooled flat-six engine producing 130 horsepower at around 95.5 kW, paired with 129 lb-ft of torque. This powerplant propelled the lightweight body—approximately 2,400 pounds—to a top speed of 131 mph, with agile performance suited for twisty roads.
- Chassis and Body: Compact dimensions similar to a first-generation Mazda Miata, with the Targa bar finished in stainless steel for durability and style.
- Roof Mechanism: Hard plastic roof stows easily, zip-out rear window for versatility; neither fully coupe nor cabriolet.
- Interior Details: Genuine wood trim on the dashboard and 356-style gauges with green numerals in pre-1968 models, adding vintage charm.
The five-speed manual transmission amplified driver engagement, making every shift a tactile delight.
Performance Breakdown
Delivering brisk acceleration, the 1966 Targa hit 0-60 mph in competitive times for its class, thanks to the low curb weight and balanced power delivery. The engine revved to a maximum of 6,200 rpm in standard form, with S variants pushing to 6,600 rpm for an extra 30 hp.

Quarter-mile times and precise 0-100 km/h figures underscored its prowess, often likened to a fighter jet’s howl on dyno runs. Early 911s demanded respect, with potential for throttle-brake oversteer if mishandled, though the Targa’s rigidity mitigated some traits.
Driving Dynamics and Ownership Experience
Behind the wheel, the Targa feels shockingly compact and responsive. The rear-engine layout delivers neutral handling on smooth roads, rewarding skilled drivers with telepathic steering feedback. Rev-matching downshifts via the manual gearbox enhance control, especially in spirited driving modes.
Owners praise its fun factor: light weight translates to nimble cornering, while the open roof invites sensory immersion—wind rush, engine growl, and road texture unfiltered. Maintenance focuses on air-cooled specifics like valve adjustments and oil changes, but originality preserves value.
Evolution from 1966 to Modern Targas
The original Targa revived flagging 911 sales and influenced future models. By the 1980s, it paired with the 911SC Cabriolet and Carrera 3.2, persisting into the 964 series. Today’s Targa 4S, like the 2016 version with 400 hp from a 3.8-liter flat-six and all-wheel drive, echoes the stainless roll hoop but adds luxury and PDK automation.
Comparing eras:
- 1966: 130 hp, manual-only, pure analog thrill.
- 2016: 400 hp, AWD, refined yet playful.
The classic remains a benchmark for purists seeking unadulterated Porsche DNA.
